However, the risks of using a high-protein diet with
carbohydrate restriction for the long term are still being studied. Several
health problems may result if a high-protein diet is followed for an extended
time:

Some high-protein diets restrict carbohydrate intake so much
that they can result in nutritional deficiencies or insufficient fiber, which
can cause health problems such as constipation and diverticulitis.
I've heard the term
"functional foods," but I don't know what it means. Can you explain?
Functional foods are foods that have a potentially positive
effect on health beyond basic nutrition. Oatmeal is a familiar example of a
functional food because it naturally contains soluble fiber that can help lower
cholesterol levels. Some foods are modified to have health benefits. An example
is orange juice that's been fortified with calcium for bone health.
Of course, all foods are functional because they provide varying
amounts of nutrients and energy to sustain growth or support vital processes.
However, functional foods are generally considered to offer additional benefits
that may reduce the risk of disease or promote optimal health.
Currently no legal definition exists for functional foods. The
Food and Drug Administration (FDA) regulates claims that manufacturers make
about functional foods' nutrient content and effects on disease, health or body
function. The FDA regulates these types of foods according to whether a food is
considered to be a conventional food, a food additive, a dietary supplement, a
medical food or a food for special dietary use.
If you want to try functional foods, choose wisely. And keep in
mind that while functional foods may help promote wellness, they can't make up
for poor eating habits. Your best bet is still to eat a balanced and varied
diet.
