Veggies may ward off breast cancer - MSNBC, 9/7/01 - "WOMEN WITH HIGH blood levels of several different carotenoid substances were two times less likely to develop breast cancer than women with lesser levels ... Perhaps the most well-known of these substances is beta-carotene ... Other members of the carotenoid family that were significant in this study include lutein (found in kale, spinach and other cooked greens), alpha-carotene (in carrots and pumpkin) and beta-cryptoxanthin (in oranges, peaches and papayas)"

Moderate Alcohol Consumption May Protect Against Silent Stroke/White Matter Disease - Doctor's Guide, 9/7/01 - ""Overall, we found that non-drinkers have the most strokes and white matter disease," ... "Light-to-moderate drinkers have fewer strokes and the least amount of white matter disease, but somewhat greater atrophy. Moderately heavy drinkers have the fewest strokes but more white matter disease and the most atrophy." ... much of alcohol's protective effect against strokes is thought to stem from its ability to raise levels of high-density lipoprotein cholesterol (HDL), the so-called good cholesterol carrier. In addition, alcohol is known to be a mild blood thinner, so it could offer protection from silent strokes caused by tiny blood clots in the brain ... Brain atrophy and drinking were linked in a dose-dependent manner, suggesting that even low levels of alcohol use may contribute to brain shrinkage"

Cholesterol Drug [Lipitor] Studied as Alzheimer's Treatment - ABC News, 9/6/01 - "We believe cholesterol from the blood, over a long period of time, also gets in the brain where it promotes the production of a toxin that causes the disorder ... There is a lot of data from studies in test tubes and animals showing that cholesterol plays an important role in the deposition of amyloid in the brain ... The idea is to make the blood act like a sponge that passively draws out the cholesterol" - That last statement sounds like he is referring to HDL [the good] cholesterol and Lipitor mostly affects LDL [the bad cholesterol] (see table, Lipitor maxed out at 9%, whereas Niaspan maxed out at a 26% rise in HDL).  See my HDL page for other ways to raise HDL. - Ben

Their risk may be reduced as much as a 60 percent"

Phytoestrogen Intake of US Women Does Not Reduce Breast Cancer Risk - Medscape, 9/6/01, user=benhess, pwd=asdfgh - "The researchers found no correlation between total phytoestrogen intake and breast cancer risk ... The highest average intake of phytoestrogens in the study population was "only 3 mg/day, a level equivalent to less than one serving of tofu per week," ... "In contrast, the average intake of phytoestrogens in Asian countries has been estimated to range from about 15 to 30 mg/day," ... it is possible that non-Asian US women are not reaching a level of intake that may reduce the risk of breast cancer"

Can You Slim Down on Peanut Butter Diet? - ABC News, 9/5/01 - "Researchers found that a diet that includes foods with high levels of monounsaturated fats like peanut butter can help people lose weight and prevent heart disease ... [The Harvard study] looked at 101 people who weighed about 200 pounds each, and divided them into two groups. One group was put on a traditional low-fat, high-carbohydrate diet; the other got richer fare — the so-called peanut butter diet — that allowed them to to get 35 percent of their calories from fat, 50 percent from carbohydrates and 15 percent from protein ... after 18 months, three times as many people on the higher unsaturated-fat diet had stuck with the program and kept the weight off. People in the low-fat diet regained an average of five pounds each" - Note:  Most peanut butters have hydrogenated oils (trans fatty acids).  A brand that doesn't is Smucker's.  On the west coast, it says Laura Scudder's but if you read the fine print, it still says Smucker's on the back.  The one with the green label has 25% less fat.  The Peanut Butter Diet at Amazon.com
