…new science shows that walking can be at least as valuable as running — and in some instances, more so. A study published this month that again plumbed data from the Runners and Walkers Health Study found that both runners and walkers had equally diminished risks of developing age-related cataracts compared to sedentary people, an unexpected but excellent benefit of exercise.And in perhaps the most comforting of the new studies, published last month in Arteriosclerosis, Thrombosis and Vascular Biology and again using numbers from the versatile Runners and Walkers Health Study, runners had far less risk of high blood pressure, unhealthy cholesterol profiles, diabetes and heart disease than their sedentary peers. But the walkers were doing even better. Runners, for instance, reduced their risk of heart disease by about 4.5 percent if they ran an hour a day. Walkers who expended the same amount of energy per day reduced their risk of heart disease by more than 9 percent.

Do check out the whole article, it’s well worth your time. By some measures of health, running is much more indicative of overall physical success than walking. Though that may be because the most-healthy people can run. But overall, walking has huge benefits even considering you’re expending fewer calories per hour.
Eating fish is known to help protect against heart disease, and the Heart Association recommends it at least twice a week.”People who choose to eat more fish are more likely to eat heart healthier diets and engage in more physical activity,” and studies testing the benefit of supplements may not be able to completely adjust for differences like these, said Alice Lichtenstein, director of the cardiovascular nutrition lab at Tufts University in Boston.The results do show that people cant rely on a pill to make up for a bad diet, she said.”It is sort of like breaking a fish oil capsule over a hot fudge sundae and expecting the effect of the calories and saturated fat to go away,” she said.

Well put! Here’s the key take-away. Eat more fish. You may not be getting the fishy benefit just from taking the fish oil.

More like before but this one doesn’t rely on mouse studies to the extent others have.
Definitely worth reading. Note the practical conclusion of the researcher himself to not totally eliminate red meat but not to eat it often.
We’d be curious as to whether the association is only with feedlot beef, or only with certain cuts of beef …. look for more studies to come.
A number of recent studies have suggested that higher dietary intake or calcium supplementation may not only not improve cardiovascular health — they may be associated with increased risk for cardiovascular events and mortality
via Calcium Supplements May Raise Odds of Heart Death in Women – WebMD.
Women getting more than 1,400 milligrams of calcium a day were more than twice as likely to die than women getting 600 to 999 milligrams a day.
If you are taking a calcium supplement, this is definitely something to discuss with your doctor. There’s a trend developing to not supplement calcium directly, if it can be supplemented naturally by your choice of foods. This is another brick in the wall on the subject of taking a daily multivitamin/mineral pill. Many if not all of the ingredients have been found to either do nothing or actually contribute toward problems down the road.
By all means do not change your supplementation without talking to your physician first. Follow their recommendations.
