...only to make up for deficiencies in their diet, but also in the hope of staving off diseases like cancer and heart disease. Though these recent trials - including two big studies in November that showed no benefit of vitamins E and C for heart disease, or vitamin D and calcium against invasive breast cancer - don't support that idea, they don't rule out the possibility that getting vitamins from dietary sources rather than supplements could have a more powerful preventive effect, or that taking different doses of supplements might be more beneficial...
...whose kitchens look a bit like chemistry labs, with all those centrifuges and tanks of liquid nitrogen used to make carrot foam and whiskey jellies. This hyper-whimsical style of cooking has caught on at many a celebrated restaurant, but are these books--whose recipes call for ingredients like calcium lactate--even remotely useful for home cooks...
...women participating in the WHI - a multiyear government trial investigating a range of women's health issues, from hormone therapy to heart disease, cancer and fracture risk - half were given 1,000 mg of calcium and 400s IU of vitamin D daily, while the other half were not. After seven years, 528 women in the supplement group and 546 women in the control group had developed invasive breast cancer, an equivalent rate, indicating no effect from the vitamin D. Earlier observational trials had found positive links between women's taking higher amounts of supplemental vitamin D and lower breast-cancer...
Confounding the results even more is the fact that calcium and vitamin D supplementation is now routine therapy for postmenopausal women to protect against bone fractures. So about 15% of the women in the placebo group were allowed to continue taking their vitamin D supplements for bone health (some were taking up to 600 IUs per day), which could explain why there was little difference between the two groups in breast-cancer rates. "This is a potential problem that confounds the results of this particular trial," says Dr. Powel Brown, a professor of medicine at Baylor College of Medicine...
...believed, had an anatomical and biological basis for their elevated taste response. Scientists have long known that different areas on the tongue map to different taste sensations. Bitter, sweet, salty, sour, and savory (umami) all have their place on the tongue, and some researchers are now arguing that calcium-sensitive sites merit their place, as well. It makes sense, then, that having more tastebuds corresponds to a greater gustatory response in supertasters.The emerging field of hedonics, the study of gustatory pleasure, is determined to pin down other biological dimensions of taste. Of course, less than 25% of the population become...
