Over 2,000 scientific studies have demonstrated the wide range of problems associated with Omega-3 deficiencies. The American diet is almost devoid of Omega 3's, except for certain types of fish.
In fact, researchers believe that about 60% of Americans are deficient in Omega-3 fatty acids, and about 20% have so little that test methods cannot even detect any in their blood.
The human brain is more than 60% structural fat, just as your muscles are made of protein and your bones are made of calcium. But it's not just any fat that our brains are made of. It has to be certain types of fats, and we no longer eat these types of fats like we used to.
