Banishing trans fats from foods is linked to reductions in the number of heart attacks and cardiovascular deaths in the years after the bans are implemented, according to data from cities and counties in New York that have made the cut.
After three years, the areas banning trans fats from eateries seemed to have an extra 6.2 percent reduction in heart attacks and strokes compared with those that didn’t, researchers report in JAMA Cardiology. Last year, other researchers reported in the Journal of Health Economics that the New York bans appeared to cut deaths from cardiovascular disease by 4.5 percent—that is, they spared about 13 lives from cardiovascular deaths per 100,000 people each year.
While the decade of bans that have gone into effect in the state offer “natural experiments” on how cutting out trans fat may affect health, the results back up a slew of older studies—animal, controlled trial, and observational studies—that found harms of trans fats, plus benefits of ousting them from people’s diets.
