Study finds huge variability in vitamin E absorption
..., that's great," Traber said. "But we really don't want to be telling people to eat more fat, and that's generally where vitamin E is found. That's why it's appealing to find an effective way of obtaining this nutrient, such as vitamin E fortification of what is essentially a low-fat food." This contro......t some will be found with the disease. "They don't want to find it," says Krull. "The USDA really should be funding this like crazy, but it's not." The practice of providing ruminant feed to farm animals has been acknowledged to be extremely dangerous, says Krull.
