THE SOY HYPE IS RIGHT. In the last few years, we are constantly reading about the seemingly endless benefits of soy products. When a food is touted in every health and nutrition column, in newspapers, magazines, and the internet, the extravagant claims are usually of questionable authenticity. But not so with soy. Epidemiological studies have shown a correlation between the consumption of soy foods and low rates of certain diseases, including coronary heart disease, hormone-dependent cancers such as breast, prostate and colon cancer, osteoporosis, and problems associated with menopause and menstrual irregularities.

Soybeans are legumes that are rich in phytoestrogens, plant-derived non-steroidal compounds that possess estrogen-like biological activity. It is the isoflavone component which is believed to provide many of the health protective effects. Isoflavones are a class of phytoestrogens that influence estrogen receptor binding, function as antioxidants, modulate sex hormone binding globulin, and exert anti-proliferative, anti-angiogenesis, and many other health promoting actions. The three main isoflavones present in soy are genistein, daidzein, and glycitin.

Epidemiological evidence suggests that populations consuming soy in fairly high amounts have lower coronary heart disease mortality. Possible mechanisms that may affect the cardiovascular system and atherosclerosis include inhibiting platelet activating factor and thrombin formation, lowering triglycerides and total cholesterol, improving arterial elasticity and inhibiting LDL oxidation.

Soy isoflavones may help prevent the development of osteoporosis at different stages. A bone-conserving action is considered to result from the direct estrogen receptor-mediated action of genistein on osteoblasts and their precursor cells. Independent of the estrogenic effects may be the enhancement of calcium absorption and retention.

A significant body of research, including epidemiological, in vitro, and animal studies, suggests that soy isoflavones may help to reduce cancer risk, specifically breast, prostate, and colon cancer. Several mechanisms have been proposed and researched include inhibition of enzymes whose actions promote cell differentiation through their effects on growth factor stimulation, inhibition of angiogenesis, and stimulation of sex hormone binding globulin.

Isoflavones are reported to exert a balancing effect on reproductive hormones in both pre- and postmenopausal women. It appears that they exert mild agonistic (estrogenic) and antagonistic (anti-estrogenic) effects, depending on the level of endogenous estrogen present. Isoflavones possess weak estrogenic activity and compete with the most potent endogenous estrogens at the receptor site, thereby reducing the total estrogen burden on the body. In this respect, the isoflavones are regarded as exerting anti-estrogenic effects.

Conversely, as natural estrogen production declines with the onset of menopause, isoflavones may help to offset this decline through their estrogenic effects. This hormonal duality is part of the reason these compounds seem to exert such a range of health effects. Theoretically, problems associated with estrogen imbalance, such as endometriosis, cervical dysplasia, breast cancer, menstrual irregularities, and symptoms commonly seen with both premenstrual syndrome and menopause, may improve with soy isoflavone intake.

Due to recent industry developments, however, one no longer must eat soy foods to get isoflavones. Several companies are now marketing soy/isoflavone pills. Given America’s proclivity for pills, it is not surprising that the supplement industry has capitalized on the excitement over the hypothesized health benefits of isoflavones. There are numerous reasons for promoting soy foods, rather than soy pills.

One is that there are other phytochemicals in soy foods, such as phenolic acids and saponins that may exert beneficial effects and that are not present in significant amounts in the pills. Two, for most people, incorporating soy foods into the diet will lead to a diet lower in saturated fat and cholesterol and higher in fiber. Three, there are potentially critical differences in isoflavone composition between the soy pills and soy foods. Four, limited dose-response data are available. Five, though results of human intervention studies remain inconclusive, there is concern that isoflavones in pill form may exert a stimulating effect on breast cancer.

Though several lines of evidence, including in vitro, animal, and human research indicate that phytoestrogens have direct beneficial effects on the arteries and bones, may reduce the risk of certain forms of cancer, and might help alleviate menopausal symptoms, the exact amount of isoflavones needed for these benefits is unknown. Finally, it must be recognized that researchers are only beginning to understand the effects of phytoestrogens. Studies have not yet clarified whether it is isoflavones in the soy foods or other components of soybeans acting alone or in conjunctions with isoflavones that are responsible for the health benefits. The health implications of these differences need to be researched and addressed.

The importance of good nutrition continues to be acknowledged as one of the key components of an individual’s well-being. Though maintaining an optimal weight is as important as the nutrients selected, it is considerably more difficult to achieve. What has become evident is that “diets” compound the problem rather than resolve it. As the dieting population implements restrictive and unsustainable plans, their weight ultimately continues to soar. The concept of dieting must be replaced with a comprehensive program that incorporates strategies to resolve food problems, nutrition education, meal planning, behavior change and physical activity if Americans are going to succeed in long-term weight management.

The relationship between cancer and nutrition is complex and multifactorial. Nutrition may play a major role in the development and progression of tumors, and conversely, not only may the neoplastic process have a detrimental effect on the nutritional status of the patient with breast cancer, but so too can the treatment modalities used to control the disease.

The nutrition management of the patient with breast cancer depends on the presence or absence of active disease, recent medical treatment, weight status, and nutrition status. The management of nutrition problems in the malnourished breast cancer patient is similar to that in other cancer patients. Obesity and weight gain, however, are more commonly seen and are a significant health risk among patients with localized breast cancer as well as those with advanced disease.

Since obesity and the risk for breast cancer increase with age, interventions that encourage weight control may influence cancer survival rates. Furthermore, obesity (25% or more over optimal weight for height) is a significant prognostic factor for those with the disease. Obesity is associated with increased estrogen production secondary to increased peripheral aromatization (i.e., the production of estrogen in fat cells). Consequently, the estrogen-sensitive tissues of obese women are exposed to more stimulation than those tissues in leaner women. The effect is significant because ovaries no longer contribute to the production of estrogen. The prognosis for these women is adversely affected by obesity. Weight gain may also be one of the most distressing side effects since it may significantly affect their self-esteem when it is superimposed on a change in body image due to the loss of a breast and/or other toxicities associated with breast cancer therapy. Because of the high frequency of weight gain, its psychological impact, and its associated health risk, efforts to control obesity and weight gain are strongly recommended.

The exciting news is that what you eat may interfere with the many stages of the cancer process. Evidence continues to mount indicating that there are hundreds, perhaps thousands, of phytochemicals (chemicals synthesized by plants) that may slow down, stop, or even reverse cancer development. More specifically, foods that can interfere with the metabolism and absorption of estrogen may present a unique mechanism to discourage breast cancer. Other mechanisms include inactivation of mutagens and carcinogens, increased excretion of carcinogens and toxic chemicals, scavenging active oxygen radicals, reducing damage to DNA and cellular membranes, and impeding or retarding the proliferation and promotion process of cancer. Though the influence of food upon cancer is complicated, not fully understood, and entwined with many other factors, your diet may make a significant difference.

The holiday season, along with holiday weight gain, sneaks upon us every year. With all the yummy food, it is hard to say no to the delectable treats found in stores, at the office, and at home. You may be thinking that eating a cookie and gaining a few pounds during the holiday season is not a big deal but studies have shown that people do not lose the weight they gained during this time. Here are a few ways you can prevent seasonal weight gain.

Holiday parties are one of the main reasons for weight gain since there is food galore. Mingling plus eating can lead to overeating quite quickly. Avoid this by not arriving hungry to a party. If it is a potluck or hors d’oeuvre format, you can eat a light meal beforehand so you can sample some food but not eat too much and you will not appear rude. If it is a holiday dinner, eat a healthy snack beforehand to manage your hunger.

Focus on other things than food when you are at a holiday event. Use the time to catch up with friends and family members you have not seen in a while. You might even play with the children for a bit, running around with them is a good way to burn calories. Limit your alcohol consumption as well. It is not just because of the calories drinks contain but also to maintain control. Drinking can cause you to lose your resolve and lead to more eating. If you feel out of place without a drink in your hand, sip on water (flat or sparkling) from an attractive glass.

Take your own delicious but healthy dish or treats with you when you go. That way you can be sure the food you eat is what you want and is good for you. Your host and other guests will certainly appreciate it. For additional tips and tricks to maintaining your healthy lifestyle during the holiday season, seek the help of a professional dietitian nutritionist.

Are you ready to become the best you possible? Nutritional Consultant Nancy Mazarin can help! Whether you are facing a medical challenge, weight management issues or just want to improve your healthy, eating right and completing proper, regular exercise will result in overall better health. Here are some reasons why you should find a physical activity you enjoy today:

It Makes You Happy

Studies confirm there is a direct relationship between exercise and an increased release of feel-good hormones. In fact, people who exercise regularly also have a lower risk of depression. Although our culture tends to emphasize medical interventions for almost every problem, exercise is a behavioral treatment that can naturally improve your health over time.

Improve Life in Bed

Regular exercise can boost your active activity in bed – keeping your muscles active promotes hormone production, and more muscle mass means more stimulation and hormone production, which helps both men and women maintain their sexual functioning. Additionally, exercise can help with your not so active bed activity – sleep.

Boost Your Brain, Fight Dementia

Both your intellectual skills and your memory benefit from regular physical activity. Free flowing, increased oxygen to the brain boosts intelligence and your ability to carry out everyday activities. Although we don’t know for certain that exercise can slow or prevent Alzheimer’s, signs point to that it helps, and regular activity helps preserve the neurons in your brain which is an advantage should you ever develop the disease.

Most one-size-fits-all weight loss programs are unrealistic and rarely result in sustained weight loss and maintenance, and can even actually be detrimental to your health. True weight loss success comes from slowly incorporating sustainable changes into your daily routine. We’ve compiled some tips to help you get started today:

Drink Water

As simple as it is, most people can’t seem to get enough. Drinking plain old water will help keep your full and is a vital part of any conditioning program, as it keeps your body happy and aids in every aspect of your body’s functions. Although it is possible to drink too much water, as long as you don’t drink more than a gallon per day you should be fine.3

Eat Whole Foods

Instead of heading towards the pantry for a snack, try to open the fridge more often. Whole, unprocessed foods, like fruits, veggies and whole grain products, are considered low-density foods and should make up about 80 percent of your diet. High-density foods, like butter and candy, provide a sweet taste but not much sustenance. Eating mostly low-density foods is a really easy way to keep your weight in check without feeling like you’re starving yourself.

Be Realistic

Don’t expect too much too soon. It’s taken you a long time to build up the habits you have now, it will take time to change them.
