Best Ways to Cook Mushrooms
Mushrooms can be a very healthy food. They’re an excellent source of plant protein and contain vitamins, minerals, antioxidants, and polyphenols. But the way they’re cooked can significantly change their nutritional quality. Spanish researchers tested various cooking methods on four popular types of mushrooms—white button, shiitake, oyster, and king oyster—and found that grilling or microwaving produced the best results. Both methods increased levels of antioxidants and polyphenols (beneficial plant nutrients), and did not significantly reduce other nutrients. However, frying or boiling greatly reduced protein and antioxidant content. Study results were published in the International Journal of Food Sciences and Nutrition.
Astaxanthin Helps the Heart
A study of runners has found that astaxanthin, a nutrient found in microscopic algae, helps the heart to work more efficiently. In particular, researchers in Utah found that at the level of effort common in long-distance runners, the heart beats a little slower than usual, indicating it isn’t working as hard to support the effort. In the study, which was published in the journal Medicine & Science in Sports & Exercise, runners took 12 mg of astaxanthin daily for 8 weeks. Researchers suggest that the supplement may also be helpful for non-athletes, as a “cardiotonic” for an ailing heart.

Curry Spice Extract Reverses Bone Loss
Curcumin, the active ingredient in turmeric, the yellow spice used in curry, is known as an anti-inflammatory for pain control and prevention of age-related inflammatory diseases. And now, an Italian study has found that it may also help reverse bone loss. Researchers compared the effects of a curcumin supplement with no supplement in a group of 57 people with osteopenia, the medical term for low bone density. To monitor effects, they tested bone in the heel, a finger, and the upper jaw, and found that daily curcumin supplements increased bone density in all three areas after 12 weeks, without any side effects. The study, published in the European Review for Medical and Pharmacological Sciences, used Meriva, a patented form of curcumin found in a variety of supplement brands.
