Study: Vitamin D may boost heart health during weight loss

May 25, 2009 10:27 pm

Supplements of vitamin D may improve cardiovascular health during weight loss, without impacting on how many pounds are shed, suggests a new study.Supplements of vitamin D may improve cardiovascular health during weight loss, without impacting on how many pounds are shed, suggests a new study.

“The results indicate that a vitamin D supplement of 83 micrograms/d does not adversely affect weight loss and is able to significantly improve several cardiovascular disease risk markers in overweight subjects with inadequate vitamin D status participating in a weight-reduction program,” wrote the authors, led by Armin Zittermann from the Clinic for Thorax and Cardiovascular Surgery in Bad Oeynhausen.

With obesity rates still high – not only in developed countries but also, increasingly, in newly wealthy emerging markets, there is considerable attention to ways to trim down waistlines. The results of the new randomised, double-blind, placebo-controlled trial indicate that vitamin D supplements may be useful as a means of boosting heart health during weight loss.

The details on D

Vitamin D refers to two biologically inactive precursors – D3, also known as cholecalciferol, and D2, also known as ergocalciferol. The former, produced in the skin on exposure to UVB radiation (290 to 320 nm), is said to be more bioactive.

While our bodies do manufacture vitamin D on exposure to sunshine,
the levels in some northern countries are so weak during the winter months that our body makes no vitamin D atall, meaning that dietary supplements and fortified foods are seen by many as the best way to boost intakes of vitamin D.

In adults, it is said vitamin D deficiency may precipitate or exacerbate osteopenia, osteoporosis, muscle weakness, fractures, common cancers, autoimmune diseases, infectious diseases and cardiovascular diseases. There is also some evidence that the vitamin may reduce the incidence of several types of cancer and type-1 diabetes.

Study details

Zittermann and his co-workers recruited 200 healthy overweight people with average 25(OH)D levels of 30 nmol/L (12 ng/mL) and randomly assigned them to receive either placebo or vitamin D for one year. All the subjects also participated in a weight-reduction program.

At the end of the study, 25(OH)D levels increased in the D group by 55.5 nmol/L, but by only 11.8 nmol/L in the placebo group. Furthermore, a 26.5 per cent reduction in levels of parathyroid hormone (PTH) were observed in the D group, compared with 18.7 per cent in the placebo group. “High blood concentrations of parathyroid hormone […] are considered new cardiovascular disease risk markers,” explained the authors.

Improvements in triglycerides levels were also observed in the vitamin D group, with a 13.5 per cent decrease noted compared with a 3.0 per cent increase in the placebo group.

Finally, levels of the marker of inflammation TNF-alpha decreased by 10.2% per cent following vitamin D supplementation, compared with 3.2 per cent in the placebo group.

“The beneficial biochemical effects were independent of the loss in body
weight, fat mass, and sex,”
noted the researchers.

On the downside, the researchers noted that participants receiving the vitamin D supplements did experience an average 5.4 per cent increase in their levels of LDLcholesterol.

Bowel Obstruction after Weight Loss Surgery

May 18, 2009 3:00 am

Bowel obstruction describes a condition in which the normal flow of gastrointestinal content is either completely or partiality blocked. This could be caused by medical conditions or medications, otherwise known as an ilius. A common example of this is seen in patients that are taking pain medications or narcotics. Another common condition is post surgical scar tissue, or adhesions.

bowel-obstruction-01

These will cause a point around which a twist of the bowel will cause a compromise of the blood flow to it and eventually result in “dead bowel”. Just
imagine what would happen if you were to place a tight rubber band around a finger? In a very short period of time, the blood supply to the finger is
compromised and if it is not quickly restored then it will result in the loss of a finger.

One of the problems with the diagnosis of bowel obstruction is that there is no absolute set of studies, such as X-ray, Cat-Scan, laboratory studies
that will be diagnostic in all cases. This is even more so in patients that have had weight-loss surgical procedures. The anatomy is modified after all weight-loss surgical procedures. This varied anatomy means that there are instances that the expected findings of bowel obstruction are not present, or there are findings that are highly suspicious for bowel obstruction if the treating physician is acutely aware of the altered anatomy.

The most critical issue regarding the treatment of bowel obstruction is early diagnosis and treatment. Blog with CT Scan images here.  Further pictures of bowel obstruction here.  

The treatment options are also different when treating a patient with bowel obstruction if they have had weight loss surgery. There are non surgical treatments that may be attempted for partial bowel obstruction (such as the nasogastric tube) that will be useless in post gastric bypass or duodenal switch patients. This is because in the duodenal switch and the gastric bypass operation, the anatomy is altered so that a partial segment of the gastrointestinal track has only limited access to outside. This means that the only way to decompress that segment is by surgery and not the naso-gastric tube.

Lactose Woes Pregnancy after Gastric Reduction

May 04, 2009 9:58 pm

Lactose intolerance is a set of symptoms resulting from the body’s inability to digest the milk sugar called lactose. Lactose is commonly found in dairy-based foods and is digested in the intestines by the enzyme lactase. The production of gas and the presence of fluid create the cramping and digestive distress that are the symptoms of lactose intolerance. Yogurt, although made from milk, is often well tolerated by people who have lactose intolerance because yogurt bacteria produce their own lactose-digesting enzyme of actase. If you have a strong reaction to lactose, you will have to become an avid labelreader. Look for words, such as whey, lactose, nonfat milk solids, buttermilk, malted milk, margarine, and sweet or sour cream. Some breads, dry cereals, cookies instant soups, breakfast drinks, and milk chocolate contain small amounts of lactose. The good news is if you are lactose intolerant after surgery it is because the area in your small bowel where lactase is secreted has probably been diverted over to the bile-containing channel. In time, your intestine may adapt by producing lactase enzymes again—if not you can always take Lactaid, a lactase supplement with your food. Hard cheeses like cheddar, low fat cottage cheese and yogurt may be tolerated better. Milk and ice cream may be tolerated the least. Remember that lactose is a milk sugar and we ask you to stay away from sugar during your weight loss period.

We can all make small changes that increase our daily physical activity. By adopting a more active lifestyle, we reduce the risk of chronic disease and have an enhanced quality of life: walking 3 to 4 mph, carrying baby up stairs, swimming moderate effort, using stairs instead of elevator, general house cleaning, walk to lunch, golfing while carrying the clubs, go shopping (walking, not buying) play on playground with your kids, dance to the radio, ride a bike to friends house, crawl around with your kids, walk your dog, baby-sit your grandchildren, play sports (don’t watch), mow the lawn, walk at the beach (don’t lay) wash your car (instead of the car wash), gardening, surf the water not the web, bag your own groceries and carry them out to the car, at work, take a walking break instead of a coffee break, volunteer at a local daycare community center.

As patient who are getting past or close to their 18 month to 2 years post-op
anniversary they may start thinking of getting pregnant. What every potential
mother to be should consider is: Has my weight loss stabilized? Have I had my vitamin levels checked and have I followed up with my weight loss surgeon before attempting to conceive? Is my OB/GYN aware of my weight loss urgery procedure and do they have experience with patient who has had weight loss surgery? Have I informed my surgeon of who my OB/GYN is? These are all important questions to consider and resolve before getting pregnancy as a post weight loss surgical patient.

Due to the nutritional imbalances that may follow all weight loss surgical procedures it is imperative to make certain that your weight loss has stabilized and you have made it past your 18-month to 2 years postop anniversary. During the weight loss period a patient is in a negative nutritional balance not getting enough calories are absorbed to support the patient’s own weight and therefore would not be able to support the addition of a growing healthy fetus. There is a possibility of birth defects if you become pregnant prior to weight stabilization and your 18-month to 2-year anniversary. The decision absolutely needs to be discussed with your weight loss surgeon prior to any attempts to conceive.

After all the above questions have been dealt with and resolved and you have been cleared by your surgeon to attempt to conceive there are extra steps needed for a post weight loss surgery pregnancy. We will inform you of these steps during the decision process with your surgeon. You always have to keep in mind that you anatomy has been changed and how your body works also has been changed. You should also start your preparation to become pregnant several months prior to attempting to conceive. You will need to be more diligent with follow-up with your OB/GYN and your weight loss surgeon during your pregnancy. Our office will work closely with your OB/GYN in your monitoring your lab work and the progression of your pregnancy

Drug Interactions Herbal Remedies

May 04, 2009 12:23 pm

Drug Interactions with Herbal remedies:

Today, one of the fastest growing supplements is the herbal remedy. Experts estimate that approximately 60-70% of the population in the United States is using some form of herbal products. What is concerning about this figure is that only a small portion of the people using herbals are communicating that fact to their health care provider. The majority of people using herbals are unaware of the potency and the interactions that herbals can have with many prescription and non-prescription medications. There are many medications that are derived from plant or herbal products such as digitalis, morphine and several anti-cancer medications. These medications easily achieve toxic levels and have very strong effects. Plant and herbs are not necessarily harmless supplements or treatments. Patients need to be aware that there is a potential for interactions with other medications and it is imperative to let your health care providers know what type of supplements or treatments you are taking over the counter.

Below is a list of a number of herbal products and their interactions with other medications both prescription and nonprescription. It is not an inclusive list and therefore anyone taking an herbal supplement or treatment should do research and always let your health care provider know what you are taking.

Patient follow up….

Follow up of patient that we have operated on takes different forms. They include review of the laboratory studies that ordered, follow up office visits, and communication with your other health care providers to name a few. None of these however are suppose to replace the routine office visits. We are very much aware of the long distances that some patient have to travel to come for their office visits. Then there are times that more time is spent waiting in our office for a relatively short visit. I can not however emphasize the importance of the a face to face office visit.

The lab results that are sent to our office are reviewed as they are received. When abnormal labs are noted appropriate measures are taken, including sending out letters that explain the abnormalities noted with recommendations that may include prescription medication. The prescriptions are also included. More frequently than not the lab results are received in our office in batches. This is why some patients receive their letters describing the deficiencies noted in their labs not all at once.

One last note regarding the follow up. We strive to be accessible at all time to patients and to their health care providers alike. We can be reached either via phone at 661-725-4847, or via email info@dssurgery.com . Every single inquiry, be from patient or another health care provider is responded to in a prompt and timely fashion.

Normal Bone Anatomy and physiology

The bones in the skeleton are not all solid. The outside cortical bone is solid bone with only a few small canals. The insides of the bone contain trabecular
bone which is like scaffolding or a honey-comb. The spaces between the bone are filled with fluid bone marrow cells, which make the blood, and some fat
cells.

You can see the difference yourself at the grocery store meat department. Here is a photograph of a T-bone steak Below is a close-up picture of a piece of the pelvic bone. It was put into a special kind of xray machine which gives lots of details.

The photograph is used with permission from Dr. Yebin Jiang from University of California, San Francisco.

If all the bones were solid, think how heavy they would be. It would be hard to run! The next page is about the cells inside the bones.

normal-bone-anatomy-02

There are three special types of cells that are found only in the bone. These cell names all start with “OSTEO” because that is the Greek word for bone.

normal-bone-anatomy-04

are large cells that dissolve the bone. They come from
the bone marrow and are related to white blood cells. They are formed from two or more cells that fuse together, so the osteoclasts usually have more than one nucleus. They are found on the surface of the bone mineral next to the dissolving bone.

are the cells that form new
bone. They also come from the bone marrow and are related to structural cells. They ave only one nucleus. Osteoblasts work in teams to build bone. They produce new bone called “osteoid” which is made of one collagen and other protein. Then they control calcium and mineral deposition. They are found on the surface of the new bone.

When the team of osteoblasts has finished filling in a cavity, the cells become
flat and look like pancakes. They line the surface of the bone. These old osteoblasts are also called . They regulate passage of calcium into and out of the bone, and they respond to hormones by making special proteins that activate the osteoclasts.

are cells inside the bone. They
also come from steoblasts. Some of the osteoblasts turn into osteocytes while the new bone is being formed, and the osteocytes then get urrounded by new bone. They are not isolated, however, because they send out long branches that connect to the other osteocytes. These cells can sense pressures or cracks in the bone and help to direct where osteoclasts will dissolve the bone.

Splenda Contributes to Weight Gain

March 09, 2009 9:16 pm

This article was taken from consumeraffair.com

A new Duke University study finds that the artificial sweetener Splenda contributes to obesity, destroys beneficial intestinal bacteria and may interfere with absorption of prescription drugs.

It’s the latest in a continuing round of studies, claims and counter-claims pitting artificial sweeteners against the powerful Sugar Association, the lobbying group for the sugar industry, which financed the Duke study.

McNeil Nutritionals, which manufactures Splenda, said the study’s findings were “unsupported by the data presented” and said Splenda may be safely used “as part of a healthy diet.” The study is scheduled to be published in a forthcoming issue of The Journal of Toxicology and Environmental Health. An advance copy appears on its Web site.

A Minneapolis-based group called Citizens for Health said the Duke study demonstrates that Splenda is a health threat. The group, headed by attorney Jim Turner, has been collecting consumer reports of side effects supposedly caused by Splenda.

“The report makes it clear that the artificial sweetener Splenda and its key component sucralose pose a threat to the people who consume the product. Hundreds of consumers have complained to us about side effects from using Splenda and this study … confirms that the chemicals in the little yellow package should carry a big red warning label,” said Turner.

Turner’s group has filed a petition with the U.S. Food and Drug Administration (FDA) calling on it to review its approval of sucralose and to require a warning label on Splenda packaging cautioning that people who take medications or gave gastrointestinal problems avoid using Splenda.

“The new study makes it clear that Splenda can cause you to gain weight and lose the benefits of medications designed to improve and protect your health. The FDA should not continue to turn a blind eye to this health threat,” Turner said.

In February, a study published in Behavioral Neuroscience cites laboratory evidence that the widespread use of nocalorie sweeteners may actually make it harder for people to control their intake and body weight.

McNeil and the Sugar Association have been waging war in the courts and the public arena for years. In 2004, the association sued McNeil, claiming it had misled consumers by claiming that Splenda was “made like sugar, so it tastes like sugar.”

Splenda’s main ingredient — sucralose — is manufactured. The process involves the use of a sugar molecule but there is no sugar in the finished product.

The Duke study was conducted on rats over a 12-week period. A lead researcher, Dr. Mohamed B. Abou-Donia, said the Sugar Association had no input into the study’s findings.


In the February study, psychologists at Purdue University’s Ingestive Behavior Research Center reported that compared with rats that ate yogurt sweetened with sugar, those given yogurt sweetened with zero-calorie saccharin later consumed more calories, gained more weight, put on more body fat, and didn’t make up for it by cutting back later. Authors Susan Swithers, PhD, and Terry Davidson, PhD, theorize that by breaking the connection between a sweet sensation and high-calorie food, the use of saccharin changes the body’s ability to regulate intake. That change depends on experience.

Problems with selfregulation might explain in part why obesity has risen in parallel with the use of artificial sweeteners. It also might explain why, says
Swithers, scientific consensus on human use of artificial sweeteners is inconclusive, with various studies finding evidence of weight loss, weight gain or little effect.

Because people may have different experiences with artificial and natural sweeteners, human studies that don’t take into account prior consumption may produce a variety of outcomes.

Three different experiments explored whether saccharin changed lab animals’ ability to regulate their intake, using different assessments — the most obvious being caloric intake, weight gain, and compensating by cutting back.


The experimenters also measured changes in core body temperature, a physiological assessment. Normally when we prepare to eat, the metabolic engine revs up. However, rats that had been trained to respond using saccharin (which broke the link between sweetness and calories), relative to rats trained on glucose, showed a smaller rise in core body temperate after eating a novel, sweettasting, high-calorie meal. The authors think this blunted response both led to overeating and made it harder to burn off sweettasting calories.

“The data clearly indicate that consuming a food sweetened with no-calorie
saccharin can lead to greater body-weight gain and adiposity (fat) than would consuming the same food sweetened with a higher-calorie sugar,” the authors wrote.

The authors acknowledge that this outcome may seem counterintuitive and might not come as welcome news to human clinical researchers and health-care practitioners, who have long recommended low- or nocalorie sweeteners. What’s more, the data come from rats, not humans. However, they noted that
their findings match emerging evidence that people who drink more diet drinks are at higher risk for obesity and metabolic syndrome, a collection of medical problems such as abdominal fat, high blood pressure and insulin resistance that put people at risk for heart disease and diabetes.


Why would a sugar substitute backfire?

Swithers and Davidson wrote that sweet foods provide a “salient orosensory stimulus” that strongly predicts someone is about to take in a lot of calories.
Ingestive and digestive reflexes gear up for that intake but when false sweetness isn’t followed by lots of calories, the system gets confused.
Thus, people may eat more or expend less energy than they otherwise would.
The good news, Swithers says, is that people can still count calories to regulate intake and body weight. However, she sympathizes with the
dieter’s lament that counting calories requires more conscious effort than consuming low-calorie foods. Swithers adds that based on the lab’s
hypothesis, other artificial sweeteners such as aspartame, sucralose and acesulfame K, which also taste sweet but do not predict the delivery of calories, could have similar effects. Finally, although the results are consistent with the idea that humans would show similar effects, human

Susan E.; Davidson, Terry L. Behavioral Neuroscience. Vol 122(1), Feb 2008, 161-173.

Animals may use sweet taste to predict the caloric contents of food. Eating sweet noncaloric substances may degrade this predictive relationship, leading to positive energy balance through increased food intake and/or diminished energy expenditure. These experiments were designed to test the hypothesis that experiences that reduce the validity of sweet taste as a predictor of the caloric or nutritive consequences of eating may contribute to deficits in the regulation of energy by reducing the ability of sweet-tasting foods that contain calories to evoke physiological responses that underlie tight regulation. Adult male Sprague-Dawley rats were given differential experience with a sweet taste that either predicted increased caloric content (glucose) or did not predict increased calories (saccharin). We found that reducing the correlation between sweet taste and the caloric content of foods using artificial sweeteners in rats resulted in increased caloric intake, increased body weight, and increased adiposity, as well as diminished caloric compensation and blunted thermic responses to sweettasting diets. These results suggest that consumption of products containing artificial sweeteners may lead to increased body weight and obesity by interfering with fundamental homeostatic, physiological processes.

Vitamin D Found To Stimulate A Protein That Inhibits The Growth Of Breast Cancer Cells

March 06, 2009 9:44 pm

Chistakos, a professor of biochemistry, has published extensively on the multiple roles of vitamin D, including inhibition of the growth of malignant cells found in breast cancer. Her current findings on the vitamin D induced protein that inhibits breast cancer growth are published in a recent issue of The Journal of Biological Chemistry. Previous research had determined that increased serum levels of vitamin D are associated with an improved diagnosis in patients with breast cancer. Prior to the current study, little was known about the factors that determine the effect of calcitrol on inhibiting breast cancer growth, she said. During the study, Christakos and coauthor Puneet Dhawan, Ph.D., examined the protein involved in the raction that can reduce the growth of vitamin D in breast cancer cells. “These results provide an important process in which the active form of vitamin D may work to reduce growth of breast cancer cells,” said Christakos. “These studies provide a basis for the design of new anticancer agents that can target the protein as a candidate for breast cancer treatment.”

Women should go for the broccoli when the relish tray comes around during holiday celebrations this season.

While it has been known for some time that eating cruciferous vegetables, such as broccoli, cauliflower, and cabbage, can help prevent breast cancer, the mechanism by which the active substances in these vegetables inhibit cell proliferation was unknown — until now.

Scientists in the UC Santa Barbara laboratories of Leslie Wilson, professor of biochemistry and pharmacology, and Mary Ann Jordan, adjunct professor in the Department of Molecular, Cellular, and Developmental Biology, have shown how the healing power of these vegetables works at the cellular level. Their research is published in this month’s journal Carcinogenesis. “Breast cancer, the second leading cause of cancer deaths in women, can be protected against by eating cruciferous vegetables such as cabbage and near relatives of cabbage such as broccoli and cauliflower,” said first author Olga Azarenko, who is a graduate student at UCSB. “These vegetables contain compounds called isothiocyanates which we believe to be responsible for the cancer-preventive and anti-carcinogenic activities in these vegetables. Broccoli and broccoli sprouts have the highest amount of the isothiocyanates. “Our paper focuses on the anti-cancer activity of one of these compounds, called sulforaphane, or SFN,” Azarenko added. “It has already been shown to reduce the incidence and rate of chemically induced mammary tumors in animals. It inhibits the growth of cultured human breast cancer cells, leading to cell death.” Azarenko made the surprising discovery that SFN inhibits the proliferation of human tumor cells by a mechanism similar to the way that the
anticancer drugs taxol and vincristine inhibit cell division during mitosis.
Mitosis is the process in which the duplicated DNA in the form of chromosomes is accurately distributed to the two daughter cells when a cell divides.

Hundreds of tiny tube-like structures, called microtubules, make up the machinery that cells use to separate the chromosomes. SFN, like the more powerful anticancer agents, interferes with microtubule functioning during mitosis in a similar manner to the more powerful anticancer drugs. However SFN is much weaker than these other plant-based drugs, and thus much less toxic. “SFN may be an effective cancer preventive agent because it inhibits the proliferation and kills precancerous cells,” said Wilson. It is also possible that it could be used as an addition to taxol and other similar drugs to increase effective killing of tumor cells without increased toxicity.

Calcium May Cut Cancer Risk

Calcium May Cut Cancer Risk

Higher Calcium Intake May Reduce Risk of Colorectal and Other Types of Digestive Cancers
Here’s yet another reason to bone up on calcium. It may help reduce your risk of cancer. A new study shows that older men and women who got the most calcium from food and supplements had a 16% lower risk of colorectal and other cancers of the digestive system than those who got the least calcium.

Among women, those cancer-fighting benefits were even stronger. Women who got the most calcium from food and supplements had a lower risk of all cancer and a 23% lower risk of cancers of the digestive system than those who got the least.

Calcium is already known to boost bone health, but researchers say previous studies on calcium’s effect on cancer have produced mixed results.

“Our study suggests that calcium intake is associated with a lower risk of total cancer and cancers of the digestive system, especially colorectal cancer,” write researcher Yikyung Park, ScD, of the National Cancer Institute and colleagues in the Archives of Internal Medicine.

Calcium May Lower Cancer Risk

The Institute of Medicine recommends 1,200 milligrams of calcium per day for men and women over age 50. Dietary guidelines also call for adults to eat three cups of fat-free or low-fat dairy foods, such as milk, yogurt, and cheese to meet their daily calcium needs. This does not include conditions or diseases that my limit the absorption of the Calcium such as weight loss surgical procedures.

One 8-ounce serving of skim milk or yogurt contains about 300 milligrams of calcium. Other nondairy sources of calcium include beans, broccoli, spinach, and other green, leafy vegetables.

In the study, researchers analyzed data from nearly 300,000 men and 200,000 women 50 to 71 who participated in the National Institutes of Health-AARP Diet and Health Study. Participants answered a questionnaire about the foods and supplements they ate, and cancer rates were linked through state cancer registries over seven years of follow up.

The results showed that total calcium intake was not associated with a lower risk of cancer in general in men, but women who got up to 1,300 milligrams of calcium per day had a lower risk of cancer overall.

However, total calcium intake from both food and supplements was linked to a lower risk of colorectal cancer and other cancers of the digestive system in both men and women.

Men who got the highest levels of total calcium per day through food and supplements had a 16% lower risk of these cancers than those who got the least amount per day. Women who get the most calcium per day had a 23% lower risk than those with the least reported intake per day.

Researchers conclude that “our findings suggest that calcium intake consistent with current recommendations is associated with a lower risk of total cancer in women and cancers of the digestive system, especially colorectal cancer, in both men and women.”

Opinion and Commentary: The above two articles that were taken from internet sites, reflect the continues and ever evolving nature of the science behind most of the recommendations made.
Just imagine the treatment of a patient with a disease process. Almost certainly the surgical and medical treatment that may have been recommended years ago may not be an option today.
This is why it is important for us, providers and patients alike to continue to stay vigilant with our surveillance of our health condition and adapt to any pertinent information that may have an impact on it. One of the most commonly asked question is about the type and the amount of the calcium that patients are required to take.
The issue of the types of the calcium supplement is discussed in great length in the FAQ section of our website (dssurgery.com, weightlossinla.com). The table outlines the differences between the types. The bottom line is that for most patients there may not be much of a difference as long as the patients are consistently taking them. There are cases however when we have recommended one type or another.
The most recommended dose is 2000-3000 mg per day in divided dose. Before some of you start calling or emailing us as to how come you were told to only take 1500 and not 2000, remember what I said earlier in this section that this is an ever evolving field. If you have taken 1500mg in divided doses and have had your yearly lab work with no further recommendation from us, do not make any changes unless instructed so.
The other most common concern regarding the calcium, is its relationship with kidney stones. Most common Kidney stone is Calcium Oxalate in post weight loss surgical patients. The treatments Does not include cutting back on Calcium. Calcium Oxalate search of our website will provide further detail.

Berry Compound Reduces Aging Effect

February 09, 2009 11:00 am

In a new study, aged laboratory animals that ate a diet rich in the berry and grape compound pterostilbene performed better than those in a group that did not eat the enriched diet, scientists with the Agricultural Research Service (ARS) have reported. Pterostilbene reversed measurable negative effects of aging on brain function and behavioral performance.

Neuroscientist James Joseph, psychologist Barbara Shukitt-Hale and colleagues at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston, Mass., collaborated on the study with chemist Agnes Rimando of the ARS Natural Products Utilization Research Laboratory in Oxford, Miss. For the two-part study, the researchers wanted to determine if pterostilbene would be effective in reversing the effects of aging on mature rats.

For the first part of the study, they tested seven stilbene compounds in cell cultures and found that pterostilbene was the most effective at preventing oxidative stress. For the second part of the study, they fed aged rats one of three diets: control, or control adjusted to include either low or high concentrations of pterostilbene. The results indicated that in aging rats, pterostilbene was effective in reversing cognitive decline and that improved working memory was linked to pterostilbene levels in the hippocampus region of the brain.

The study results are the latest in a series of ARS cell culture and animal model studies published in the last decade that shed light on relationships between various dietary components and brain function while aging. The authors noted that there are additional berry compounds showing similar
potential, which they continue to investigate in animal and cell models. The researchers followed protocols approved by the Frederick, Md.- based Association for Assessment and Accreditation of Laboratory Animal Care International and a Boston, Mass.-based Internal Animal Care Review Committee.

The study was published recently in the Journal of Agricultural and Food Chemistry.

Avocado

January 12, 2009 6:55 am

Avocado- Can I have some?

“Avocados Are Not Just a Pretty Face, They’re Good for You, Too.” According to a in the LA Times, a “functional food” is defined as one that helps maintain a healthy physique and improves the body. Now that’s a little vague, but primarily this definition is being used to single out those foods that seem to be naturally blessed with combinations of phytochemicals that may help fight certain chronic diseases such as cancer and heart disease. Now avocados have been elevated to “functional food” status. According to the director of the UCLA Center for Human Nutrition, avocados include a cholesterollowering agent and are said to act as an antioxidant. Although naturally high in fat (monounsaturated like olive oil) they can be added to diabetic and heart-healthy diets. Avocados have more potassium than a banana and contain almost 10 % of an adult’s daily requirement of iron. They are low in sodium, and provide good quantities of betacarotene, vitamins B6, C and E, folic acid and copper. Because they are a vegetable product, they have no cholesterol. The average avocado contains 112-177 calories depending on size and type. A slice of avocado on a low-fat cracker can provide extra protein as well. Bon Appetite!!

CALORIES = calories per minute for a 150 pound individual

Total calories burned = (W/150) x C x M

Where:

W = Your weight in pounds

C = Number from table above for specific activity

M = Number of minutes activity performed

Example: If a 180 pounds male swims for 30 minutes, the total calories burned are:

Calories = (180/150) x 8.3 x 30 = 299 calories

 

How much water is enough?

Most of us do not adequately hydrate our bodies, especially in the summertime and after we work out. This is critical for our post-op patients. To find out how much water you really need: take your weight, divide it in half and divide by 8.

Example:

A 300lb person — divided in half = 150 divided by 8 = 18 ½ glasses of water/ day.
A 150 lb person, divided in half = 75 divided by 8 = 9 glasses water/day.
Drinks containing caffeine and alcohol will only dehydrate you more.
