Finasteride as a Chemopreventive Agent in Prostate Cancer - Medscape,

prostate cancer"
Diabetes Linked to Alzheimer's Disease - WebMD, 6/26/07 -

ACE inhibitors and
ARBs can be said to be useful in
preventing or delaying progression of nondiabetic patients into type 2 diabetes"
An Evidence-Based Me dicine Approach to the Appropriate Selection of
Supplementation with Omega-3 Fatty - PowerPak.com, 6/1/07 -
"Fish oils EPA and DHA appear to result in different
physiologic effects than their precursor, the plant-derived ALA.12-14
Biosynthesis of EPA or DHA from ALA is limited. Although dietary consumption of
ALA alone will prevent EFA deficiency, emerging scientific evidence indicates
that for optimum health or body function, the fish oils EPA and DHA should also
be ingested regularly, either from dietary or supplement sources. Use of ALA
supplementation alone, even with high dose or long-term consumption, does not
result in lowered triglyceride concentrations seen with EPA or DHA, nor does it
demonstrate similar in vitro susceptibility to oxidation of LDL cholesterol"

effect. Whereas PIO-treatment increased total HDL particle concentration and
size, ROSI-treatment decreased them; both increased HDL cholesterol levels"

chemicals—including various flavonoids and
resveratrol—missing from other alcoholic beverages"

died. In another study, mice who took resveratrol lost weight, increased
metabolism and doubled their exercise endurance"

Michigan, estimated that a pill mimicking the effects of calorie restriction
might increase human life span to about 112 healthy years"
