5. Hydrogenated Oil
Depression is, in essence, a malady of the brain that causes all sorts of physical symptoms. When you eat foods made with or cooked in hydrogenated oils, it negatively affects both brain and body.
Beyond attacking heart health, the trans fats found in hydrogenated oil can clog arteries and limit blood flow to the brain, leading to depression. The circulatory system is a key piece of the mind-body connection; impede that and you are likely to suffer from low mood and a weak body.
