3 SHARPEN YOUR BRAIN
Fats not only make you stronger and leaner, they also make you smarter. Omega 3, a type of polyunsaturated fat known as an essential fatty acid (because your body can’t produce it, so it has to be consumed through your diet), has been linked to a huge number of health benefits. These include a better-functioning brain and reduced risk of depression and dementia. The best source of omega 3 is coldwater oily fish, such as salmon.
