Many bodybuilders can identify foods that contain good fats, and bad fats. They know steak is good. They know ice cream is bad. They know milk might lie somewhere in the middle. But a poor understanding of the definitions of the three types of fat, and examples of each, could lead to the bodybuilder missing out on some really good fats that he could be consuming every day. More importantly, it could lead to a bodybuilder consuming fats, which are detrimental for long-term health, and avoiding those fats, which can actually improve health. Here are the basics.

Unsaturated Fats

These are the good fats which keep us healthy, and should be consumed daily. They make the brain and other organs function. They keep the immune system strong. Finally, they keep joints strong and aid in muscle growth. These fats can be found in salmon, sunflower seeds, avocados, and peanuts.

Saturated Fats

These fats are semi-healthy and should be consumed several times per week. They contribute to brain function, but also raise cholesterol levels. Saturated fats can be found in meat and dairy products.

Trans Fats

These are the 'bad' fats, which should be avoided. Trans fats actually lead to some cancers, fat gain, and limit muscle growth. Found in French fries and any other food cooked in hydrogenated oil, these fats have no benefits for bodybuilders.

Unsaturated fats should be a daily staple in all bodybuilders' diets - consumed at most meals. Sirloin, salmon, peanut butter, eggs, chicken, olives, and other sources of good fats are required for long lives and great physiques. Additionally, supplementing with Essential Fatty Acids (EFA's) in the form of Fish Oil tablets is also required. Bodybuilders should work to learn everything they can about good and bad fats. It will help with their progress, will keep them healthier, and will possibly be very useful to educating those around them.
