4. Saturated, Trans Fats:
Saturated and trans fats greatly increase bad cholesterol in the blood. If the body fat increases, you are more likely to develop heart disease. That's why doctors recommend eating less red meat, full-fat dairy products and foods made with hydrogenated oils. Instead, eat foods that contain monounsaturated and polyunsaturated fats like almonds, walnuts, olive oil, and avocados.
