? Men with early-stage prostate cancer may be able to slow or even reverse cancerous changes in cells by making dramatic lifestyle changes. Researchers at the University of California at San Francisco studied 93 men with early-stage prostate cancer. Half made lifestyle changes; half did not. The changes included a vegan diet, soy, fish oil, vitamin E, selenium, vitamin C, walking and stress management. After one year, tests showed that prostate cancer cell growth slowed 70% in the lifestyle group, but only 9% in the control group.

? A high intake of the carotenoids beta-cryptoxanthin and zeaxanthin may reduce the risk of arthritis. Researchers in the U.K., studying 25,000 people, found that the average intakes of beta-cryptoxanthin and zeaxanthin?pigments in dark green or bright-colored plant foods?were 40% and 20% lower, respectively, in participants who developed arthritis than in those who didn’t. And those with the highest intakes of beta-cryptoxanthin were only half as likely to develop arthritis over seven to 15 years as those with the lowest intakes. Oranges, bell peppers, papaya and watermelon are especially rich in beta-cryptoxanthin. Just one glass of
orange juice a day may lower risk.

? People with severe asthma may have greater antioxidant needs than other people. Australian researchers recently studied 81 people with asthma?28 with severe disease?and 43 without. They found that those with severe asthma had blood levels 64% lower in vitamin C and 12% lower in vitamin E than those without asthma or with mild-to-moderate asthma. Because intakes of these vitamins did not differ significantly between the groups, people with asthma might require more.
