This is becuse many of the oils that go into our processed foods, like corn oil, are very high in omega-6s but not omega-3s.Many people Brain Plus IQ believe that this is causing an omega-3 deficiency and contributes to all kinds of brain and body problems that include depression, Alzheimer's, heart disease, diabetes and even some cancers.There are a few different types of omega-3s. Some are in cold-water fish, like Salmon and Mackerel and others are in plant sources like flax seed and walnuts. The kind found in fish are the ones that seem to be important for brain function and mood regulation and the kind found in plants are more important for diabetes prevention. Our bodies have the machinery to convert one kind of omega-3 to the other, but it is very inefficient and doesn't work that well in most people. http://www.healthcaresups.com/brain-plus-iq-scam/
