DHEA is supposedly used to increase testosterone production, preserve youth, protect against heart disease, cancer, diabetes, and osteoporosis, invigorate sex drive, facilitate lean tissue gain and body fat loss, enhance mood and memory, extend life, and boost immunity to a variety of infectious diseases (including AIDS) 1. Continual use can lead to physiological or emotional drug dependency. This often causes cyclical dependency on "uppers" (amphetamines) or "downers" (barbiturates) (barbiturates blunt or tranquilize the "hyper" state brought on by amphetamines).
2. General side effects include headache, tremulousness, agitation, insomnia, nausea, dizziness, and confusion, all of which negatively impact sports performance.
3. Prolonged use eventually requires more of the drug to achieve the same effect because drug tolerance increases; this may aggravate and even precipitate cardiovascular and psychological disorders. Medical risks include hypertension, stroke, sudden death, and glucose intolerance.
4. Amphetamines inhibit or suppress the body's normal mechanisms for perceiving and responding to pain, fatigue, or heat stress, severely jeopardizing health and safety.
5. Prolonged intake of high doses of amphetamines can produce weight loss, paranoia, psychosis, repetitive compulsive behavior, and nerve damage.
-Beyond meeting the three basic nutrition needs for survival, hunger satisfaction, and preventing adverse effects, functional foods, and their bioactive components promote well-being, health, optimal bodily function, and reduce disease risk.
-Primary physiologic targets include gastrointestinal functions, antioxidant systems, and macronutrient metabolism.
