Two helpful additional things to help Brain function are Selenium and Ginko Biloba.

we know what VK means by "processed" but technically it should be called something else, like "overly processed" and "poisoned".
When maize gets nixtalized [sp?] to make masa, it's "processed". When you catch a fish, gut it, clean it to prepare to eat, you've "processed" it. Wheat gets milled to make flour, it's "processed". Pretty much everything gets processed unless you pick it off the vine and eat it raw and unwashed, right there.
Meat is processed as well of course. I've never seen a person bite the drumstick of a dead turkey. Ew. lol.
But VK is right; been trying to clean out our diets for 20+ years now. Organic makes a HUGE difference.
It's also expensive, harder to get, and making everything homemade from scratch takes me all day long.

For years, I've maintained that food in it's basic form is healthier by far than anything else including vitamins and supplements. Season to taste but be sure your seasonings are also in basic form.

Yup!
