What are hydrogenated fats and why are they bad for you?

Hydrogenated fats are actually similar to saturated fats of animal origin but have a greater detrimental effect on health because they contain trans fatty acids that promote the increase of LDL cholesterol and reduce HDL lipoproteins.

What are hydrogenated carbohydrates?

Hydrogenated fats are a group of fats that are obtained through the process of “hydrogenation”, which is a chemical reaction through which one or more multiple carbon bonds are reduced to simple bonds by the addition of hydrogen atoms, all at temperatures and high pressures.

What are hydrogenated foods?

What foods contain hydrogenated fats?

  • in margarine,
  • in vegetable cream.
  • in packaged baked goods such as biscuits, croissants, snacks, crackers, bread sticks, taralli, potato chips in bags.
