It is written that approximately every seven years the biological body ( our personal living organism that we call "" me ""), renews itself. You can Google this up. Our body re-builds itself from our smallest cells to complete functioning organs. If this is the case then it is common sense to seek out the best building materials. We are individuals. What is best for some is not best for all. The secret of good nutrition for oneself is a matter of listening to your inner urges, these indeed are probably indicating the way to go. At different times you will need to be eating that which is needed by the re-building process. Now for the punch line. What, predominately were your ancestors eating? And their ancestors? Were they healthy? Did they have readily available selections or variety of foodstuffs.? Or was the situation dire due to where and under what conditions their lives had to be lived? The Bantu Nation, as opposed to the National people from the Artic Circle. So if your ancestors were from the Artic circle, then you should include plenty of fish in your diet. And, preferably live in a cool climate. Some of my ancestors were Spanish, so I have olive oil, sardines, oranges, dates, and pomegranites. ( HE HE HE )westwind.
