Although there has been a lot of focus on low-fat diets to lose weight and for health benefits, there are also dangers to not including enough fat in your daily intake of food.
A big risk is vitamin deficiencies. Vitamins A, D, E and K are generally only absorbed by the body in the presence of fat, and all are vitally important for ongoing health.
A lack of vitamin A can lead to dry skin, night blindness, increased susceptibility to infections, and problems with bone and tooth development. Low levels of vitamin D can cause weak bones, and too little vitamin K can lead to increased bleeding.
Omega-3 fatty acids are essential for brain development, and a deficiency of these particular fats can result in learning problems and an increased risk for certain types of dementia.
