Diet powders, or meal-replacement powders, are usually protein-based drink mixes that are combined with water, milk, or juice. They’re intended to be a quick and nutritious alternative when you can’t get a “real” meal.
Diet powders have long been a source of nutrition and protein for athletes, weight watchers, and bodybuilders, but are now formulated for everyday use as well. Continue Reading »

Fewer than half of Americans realize there are two types of dietary fat that actually help their hearts, a new survey shows.So, while many have heeded the warnings about the cardiovascular dangers of trans fats and saturated fats, the American Heart Association (AHA) now thinks people need to pay more attention to the cardiovascular benefits conferred by polyunsaturated and monounsaturated fats.

Green Tea for Weight Control

Why do dieters use it?*
Some dieters say that green tea promotes weight loss.
What do the advocates say?*
Green tea is a good choice for people on a weight-loss program because it can help them to lead a healthier lifestyle. For example, substituting green tea for coffee with cream and sugar not only saves calories but also supplies a lot of healthful substances, such as polyphenols and flavonoids, that can help improve one’s overall health.
Green tea contains a small amount of caffeine, so it serves as a mild appetite suppressant as well. Continue Reading »
Benefits of High Fiber Food
Posted by admin on 06 Sep 2007 | Tagged as: Diet, Food
While the current American diet averages only about 10 grams of dietary fiber per day, intakes of 25 to 40 grams of fiber per day are linked to a reduced risk of developing a host of chronic diseases, including cancer, heart disease, and gastrointestinal conditions. High-fiber diets have also been suggested to protect against obesity.
Fiber falls into two general categories—water-soluble (found mostly in oats, fruit, and legumes) and water-insoluble (found mostly in grains and vegetables). As each type of fiber has different benefits, most people on high-fiber diets are generally advised to increase their intake of foods that feature both soluble and insoluble fiber. Continue Reading »
Dietary Prevention: Cardiovascular Disease
Posted by admin on 30 Aug 2007 | Tagged as: Cardiovascular Disease, Diet
Preliminary evidence has linked high salt consumption with increased cardiovascular disease incidence and death among overweight, but not normal weight, people. Among overweight people, an increase in salt consumption of 2.3 grams per day was associated with a 32% increase in stroke incidence, an 89% increase in stroke mortality, a 44% increase in heart disease mortality, a 61% increase in cardiovascular disease mortality, and a 39% increase in death from all causes. Intervention trials are required to confirm these preliminary observations.
Moderate alcohol consumption appears protective against heart disease. However, regular, light alcohol consumption in men with established coronary heart disease is not associated with either benefit or deleterious effect.
A high intake of carotenoids from dietary sources has been shown to be protective against heart disease in several population-based studies. A diet high in fruits and vegetables, fiber, and possibly fish appears protective against heart disease, while a high intake of saturated fat (found in meat and dairy fat) and trans fatty acids (in margarine and processed foods containing hydrogenated vegetable oils) may contribute to heart disease.
In a preliminary study, the total number of deaths from cardiovascular disease was significantly lower among men with high fruit consumption than among those with low fruit consumption. A large study of male healthcare professionals found that those men eating mostly a “prudent” diet (high in fruits, vegetables, legumes, whole grains, fish, and poultry) had a 30% lower risk of heart attacks compared with men who ate the fewest foods in the “prudent” category.
By contrast, men who ate the highest percentage of their foods from the “typical American diet” category (high in red meat, processed meat, refined grains, sweets, and desserts) had a 64% increased risk of heart attack, compared with men who ate the fewest foods in that category. The various risks in this study were derived after controlling for all other beneficial or harmful influencing factors.
A parallel study of female healthcare professionals showed a 15% reduction in cardiovascular risk for those women eating a diet high in fruits and vegetables - compared with those eating a diet low in fruits and vegetables.
