Lycopene stops the progression of BPH

Benign prostatic hypertrophy is estimated to affect half of men in their 50s,
increasing in prevalence to up to 90 percent of men age 80 and older. In this
newly published study researchers of the University of Hohenheim in Stuttgart
enrolled 40 men with biopsy-confirmed BPH (Benign Prostatic Hypertrophy) and
a serum prostate specific antigen (PSA) concentration of greater than 4.0 micrograms
per liter. The men were randomized to receive 15 milligrams of lycopene per
day or inactive placebo for six months. Prostate specific antigen was measured
in blood samples drawn during screening, and after one, three, and six months.
Prostate volume was determined via digital rectal examination and prostate weight
by trans-rectal ultrasonography.
Supplementation with the carotenoid lycopene slowed the growth of the prostate
in the men. After six months, men who received lycopene experienced a decrease
in PSA levels, while those who received the placebo experienced no change. Prostate
enlargement progressed in the placebo group but prostate size remained the same
in those that received lycopene. Although both groups reported improved BPH
symptoms following the trials, a greater effect was report by men who received
lycopene. The study is published in the January, 2007 issue of the Journal
of Nutrition.
Yale University; Cocoa clearly improves blood flow hemodynamics and
function of the arteries
In a six-week trial, healthy adults were given 8 ounces of cocoa, 8 ounces of
cocoa with sugar, or placebo each day. The scientists from Yale University’s
Yale Prevention Center used high-frequency ultrasound after each serving to
check blood flow progress. The results were clear; improved blood flow resulted
from both cocoas but was better in the sugar-free cocoa. This could improve
or help prevent high blood pressure and cardiovascular disease. The paper was
presented recently at the annual American College of Cardiology scientific meeting
in New Orleans.
