He told Boston.com: "Eighty percent of what they eat is vegetables and whole grains: brown rice, quinoa, millet, beans. The other 20 percent is lean meats: grass-fed organic steak, duck every now and then, and chicken. As for fish, I mostly cook wild salmon.

"[Tom] doesn't eat nightshades, because they're not anti-inflammatory. So no tomatoes, peppers, mushrooms, or eggplants. Tomatoes trickle in every now and then, but just maybe once a month.

"It's very different than a traditional American diet, but if you just eat sugar and carbs - which a lot of people do - your body is so acidic, and that causes disease. Sugar is the death of people."

Meanwhile, despite tending to avoid sugar, the 38-year-old American football star previously revealed his grandma's secret biscuit recipe is made over and over again during the holiday period.

He shared: "My grandma always had a biscuit recipe that she used to make for us, so every holiday - Thanksgiving, Easter, Christmas - there is biscuit making. That's a little bit of tradition in our house now."
