Variety of Foods: The Good and the Bad

Variety of Foods: The Good and the Bad
You will thrive best if you can learn to eat an array of fresh, natural foods to get the wide range of nutrients that are necessary for vibrant health.

Different foods provide different nutrients, so the greater variety of nature’s bounty in which you partake, the better health you will enjoy.

Eat an abundance of fruits and vegetables and try new ones every chance you get.

Look for brightly or deeply colored varieties as they are high in anti-aging antioxidants.

Variety is also important when choosing animal protein sources. Red meat poultry, nonfat dairy, whey protein, seafood, and fish all have very different nutritional profiles.

Try not to eat the same type of meat or fish day in and day out.

A mixture of protein sources will supply you with an array of healthful nutrients and still help you to avoid the over-consumption of potentially toxic substance that may be present in specific meats or fish.

For instance, tuna is fine once or twice a week, but if you ate it every day, you might end up accumulating toxic amounts of mercury.

Lean red meat is great in moderation, but when eaten in excess you might absorb too much iron, saturated fat, and heterocyclic amines (carcinogens).

Lean chicken breasts are low in fat but don’t have the beneficial omega-3 fats found in fish and seafood, or the high zinc levels of red meats.

Variety, however, have a dark side. The dramatic rise in America body weight over the past twenty-five years is paralleled by a line documenting the number of new man-made foods introduced into the diet over the same time period.

They are often advertised as low fat, low carb, or vitamin-fortified, but nearly all of these synthetic, caloric-dense delicious new foods are designed to entice us into overeating.

A whole host of designer “fat free” highly processed foods were gobbled up by the American public as it packed on pounds of fat tissue faster than grain-fed cattle in feed lots.

The Importance of Adequate Fiber Intake

The Importance of Adequate Fiber Intake
The importance of adequate intake of fiber to the improvement of health is demonstrated by some of the physiologic effects exerted by its various components. Particularly noteworthy are the hypoglycemic and hypolipidemic effect of soluble fiber. Slowing the absorption rate of carbohydrate can be very helpful to the diabetic in regulating blood glucose levels and lowering serum cholesterol levels presently appears to have significant benefit in the prevention of atherosclerosis.

Adequate fiber intake has been implicated in control of various gastrointestinal disorders, including diverticular disease, gallstones, irritable-bowel syndrome, inflammatory bowel disease, and constipation. It was suggested that fiber, especially wheat bran, is effective in the treatment of constipation; but evidence for the effectiveness of fiber in control of the other diseases seems equivocal. Nevertheless, populations with high fiber intakes have a lower incidence of these gastrointestinal disorders.

A generous fiber intake appears to be beneficial to some individual in their efforts at weight control. The bulk provided by fiber may have some satiety value, so that high fiber foods possibly reduce the hunger pangs associated with caloric restriction while simultaneously somewhat reducing nutrient utilization. The anti-toxic effect of fiber is a physiologic role often overlooked. Results of studies on experimental animals, particularly growing rats, have shows the protective effects of selected fiber supplements against a variety of toxic agents.
