A recent study revealed that trans fats increase heart attack risk. The study shows that butter and other saturated fats are not connected to an increased risk of heart disease or death. The trans fats, and not the saturated fats from animal products, are connected to an increased risk of coronary disease, stroke, type 2 diabetes and death, the recent study shows.
Assistant professor and lead author of the study, Russell de Souza said that for a very long time, people have been advised to cut out fats from their diets. Trans fats have no real benefits for the health and increase the risk of heart disease, however, the saturated fats are less clear as to what they do to our bodies.
Saturated fats mostly come from animal products, like egg yolks, salmon, meat, milk and butter. They also come from some plants such as palms oils and chocolate. Trans fats are usually produced industrially from oils coming from plants for use in packaged baked goods, snack foods and margarine. The process is called hydrogenation.
Present United States guidelines highly recommend limiting the intake of trans fats to less than one percent and saturated fats to less than 10 percent of energy per day in order to decrease the risk of strokes and heart diseases.
The team of scientists looked into the results from 50 observational studies regarding the connection between trans and/or saturated fats and the outcome of health in adults. The researchers didn’t find any clear connection between death for any reason, such as coronary heart disease, ischemic stroke, type 2 diabetes and cardiovascular disease and a higher intake of saturated fats.
The authors of the study said that if they want to advise people to eat far less trans and saturated fats, they have to offer them a greater choice of food. They also added that people should replace foods that contain a high amount of these kinds of fats, like donuts and high-fat or processed meats, with whole grains, nuts and vegetable oils.
People should choose a variety in their diets and include nuts, vegetables, legumes, fruits and grains and stop eating so much sugars, refined starches and processed trans fats. Long story short, the advice is still pretty much the same: don’t eat just one type of food and opt for more of the good kind than the bad kind.
