Cod Liver Oil => GOOD

It is one of the most reliable and concentrated food sources of four nutrients that are essential to human health: DHA, EPA, vitamin A, and vitamin D. These four nutrients are needed for:

• Healthy skin
• Strong bones and teeth
• Healthy joints
• A healthy cardiovascular system
• A healthy nervous system and prevention of depression and other mood disorders
• A healthy digestive tract
  
  
  
  DHA is a fatty acid that is essential to the health of your nervous system and eyes.
  It is vital to preventing depression. If you suffer from intermittent or chronic depression, you want to get DHA through your diet every day.
  If you're pregnant or you plan on getting pregnant, it's best that you eat foods with DHA on a regular basis in order to support proper development of your baby’s nervous system and prevent depression during pregnancy and after your baby arrives. I am convinced that the vast majority of cases of post partum depression can be avoided just by ensuring adequate intake of DHA.
  
  EPA is a fatty acid that promotes a healthy cardiovascular system and decreases inflammation throughout your body. Its anti-inflammatory properties make EPA especially helpful to people who suffer with arthritis. EPA is also closely linked with your emotional health, with many studies showing that it plays a strong role in preventing depression.
  
  Vitamin A is necessary for proper vision, healthy skin, and strong mucosal linings, including the lining of your digestive tract. Many skin and digestive disorders cannot fully heal without adequate vitamin A intake.
  
  Vitamin D is needed to reduce risk of virtually every type of cancer.
  Vitamin D is essential to maintaining strong bones and teeth. It enhances the strength and efficiency of your immune system, and decreases your risk of developing autoimmune conditions. Vitamin D helps your body regulate its blood sugar levels, playing an important role in preventing type 2 diabetes. Finally, vitamin D is one of several nutrients that are necessary for preventing high blood pressure.
