 The total antioxidant capacity of our diet may also be protective against stroke, in contradiction to all the pill studies that failed to show benefit. But what they did in this study was to take into account all antioxidants present in actual food in the diet, including thousands of compounds in doses obtained from a usual diet, not one or two in high doses in pill form. Stroke is the world's leading cause of death after heart disease. The buildup of oxidized fat is considered the hallmark of fatty streak formation, the earliest manifestation of atherosclerotic plaques. Yes, the oxidation of fat can happen outside the body every time we cook it, but oxidized fats are not only formed in foods, but may also be generated during digestion, especially in stomach acid. Our stomach may be like a bioreactor for the oxidation of high fat cholesterol-rich foods. See, muscle foods contain large amounts of endogenous catalysts which accelerate fat oxidation. As poultry sits in our stomach, the oxidation may build up minute by minute. See, chickens are blood of only about half their blood, and the remaining residual can be a powerful promoter of fat oxidation. So there are those in the industry advocating an additional decapitation step to reduce all that oxidation. But if oxidation is the problem, antioxidants may be part of the solution. Total antioxidant capacity from diet and risk of heart attack. We know antioxidant pills don't work, while extensive experimental data have revealed a central role for oxidative stress in the stiffening of our arteries and suggested a potential role for antioxidant treatment in cardiovascular disease. Experimental data has not translated into clinical benefit. Most antioxidant vitamin trials have failed to reduce heart disease and death and may in fact even be detrimental. As a result, some have even questioned the supposed central role of oxidative stress in the disease process, described as a critical blow to the whole free radical theory of aging, the fact that pills didn't work. But high-dose single antioxidant supplements are not a good substitute for the very complex antioxidant network of thousands of compounds in foods, present at concentrations far below those used in the pill trials. No one had ever looked at the overall effect of the complex antioxidant network in diet in relation to our leading killer, coronary heart disease, until now. The total antioxidant capacity measures in one single value the free radical reducing capacity of all antioxidants present in foods and all the synergistic effects. And in this large prospective population-based cohort study, they observed that higher total antioxidant capacity of diet was associated with lower risk of incident heart attack in a dose-response manner, meaning potentially the more high antioxidant plant foods in our diet, the better.
