Poor Nutrition = Poor Immunity / Great Nutrition = Great Immunity
Scientists regularly speak about how the quality of your diet can modulate your immune potential. It has been well established that the levels of certain nutrients relate directly to immune capacity.
In 1997, researches from the United States Department of Agriculture (USDA) published evidence in the American Journal of Clinical Nutrition on research they conducted with NeoLife Carotenoid Complex. In that data Carotenoid Complex is capable of boosting specific markers of immune competence in an otherwise carotenoid deficiency diet.
That effect has been shown several times since then, making dietary carotenoids an important immune competence indicator. It is, at least in part, because of this relationship between carotenoids intake is also associated with cancer prevention.
