Hi,

Number 5 occurs in people without the enzymes to handle these foods. So if these foods cause headaches, they always will: there are no half measures.

Three more tips

6. Ensure adequate intake of water (dehydration causes headaches)
7. Ensure B vitamin intake is being met (I think it is B2, but B vits should be taken together)
8. Eat apples, washed and with skins.

Cheers
