IN THE NEWS FISH COMBATS HEART DISEASE Omega-3 fatty acids can slow the progression of fatty buildup in the arteries of patients with heart disease, according to a German study in the April 6 issue of the Annals of Internal Medicine.
Researchers determined eating 1.5 grams of omega-3 fatty acids daily for two years can slow fatty buildup. They recommend eating fish twice weekly or taking fish oil concentrate to help prevent secondary coronary heart disease.
Dr. Clemens von Schacky of the University of Munich, Germany, followed 223 patients with coronary artery disease for two years. At the beginning of the study, researchers used angiograms to document the extent of the blockage in patients’ heart arteries. Then, half the patients received 1.5 grams of fish oil daily, while the other half received a placebo.
Of the 80 placebo patients who completed the study, 36 showed mild progression of fatty buildup in their arteries, five showed moderate progression, and seven showed mild regression of heart disease.
Among the 82 patients who received fish oil, 35 showed mild progression, four showed moderate progression, 14 showed mild regression, and two showed moderate regression.
VITAMIN E CAN PROTECT AGAINST STROKE Even modest amounts of vitamin E are protective against ischemic stroke, according to research shared at the annual meeting of the American Academy of Neurology in April.
Research conducted at New York’s Columbia-Presbyterian Hospital showed that taking vitamin E supplements can reduce the risk of a stroke by 53 percent. Forty-six percent of subjects in the study took vitamin supplements.
Ischemic stroke is caused by a clot or arterial disease blocking blood flow to the brain.
GREEN TEA GOOD FOR INHIBITING BLOOD VESSEL GROWTH A study featured in the April 1 issue of Nature reinforces green tea’s already positive reputation.
Swedish researchers at the Karolinska Institute in Stockholm determined that green tea contains a compound called epigallocatechin-3-gallate (EGCG), which helps inhibit blood vessel growth. Researchers believe this could be useful in preventing tumors from forming new blood vessels, which are necessary for their survival.
Other studies have shown EGCG blocks an enzyme needed for cancer cell growth and keeps cells from becoming cancerous without harming surrounding healthy cells.
Researchers caution against heavy consumption of green tea for women who are pregnant and people recovering from wounds.
AN APPLE A DAY COULD KEEP THE DOCTOR AWAY Apple lovers may lower cholesterol buildup on artery walls as they snack, according to a study in the April 16 issue of Life Sciences.
Apples and apple juice contain significant amounts of antioxidants, which reduce rates of LDL oxidation in human blood cell cultures. The potential inhibition ranged from nine percent to 34 percent depending on the extracts used: apple pulp, whole apple, or apple peel.
Researchers recommend additional study into how various processing methods affect the antioxidant content of apple juice.
BROCCOLI DESERVES A GOOD REPUTATION Filling up on select veggies may benefit the bladder, according to a study in the Journal of the National Cancer Institute.
The study revealed that the higher the intake of cruciferous vegetables, especially broccoli and cabbage, the lower the risk of bladder cancer. In contrast, the intake of yellow or green leafy vegetables or carotenoid-rich vegetables was not associated with the same benefits.
This is especially important news for men, who experience bladder cancer at a rate three to four times higher than in women.
