You know what reduces risk of heart attack by 40% and has a net positive cash benefit as opposed to a massive cost? The mediterranian diet as defined by the studies which show the benefit. Even better is whole food-plant based. See the heavily cited study called "The Mediterranean Diet, its Components, and Cardiovascular Disease". Of course, these health issues don't impact the young age groups very much. Also, the mediterranian diet reduces the risk of recurrent heart attacks by 40%. See the study "Mediterranean diet and prevention of coronary heart disease in the elderly".
