Try to get an appropriate proportion of carbs-proteins-fats. Don’t rely too heavily on processed food, try to eat very nutrient-rich foods.

Proteins that come with Omega 3s are great. We tend to lack omega 3s in our diets, and I believe this causes a lot of problems. Fish are good sources, flax seed also has omega 3 I think.

Eat fruits and veg rather than breads and other overly processed carbs. Fruits release glucose much more slowly, and whatever you can do to reduce insulin spikes is ultimately good for you in a lot of ways. Whole grains, fruits. "Whole of the grain".

Some foods are better cooked, some are better raw. I think carrots and tomatoes break down in a good way when cooked. Other things tend to lose nutrients to the cooking medium (water, if boiling) or evaporated through the steam. Not necessarily bad, especially if you trap those nutrients with a lid and use the extra water as a base for a sauce, or maybe a broth later on, it’s all good.

Eat rich natural foods - rich in nutrients. Kale, chard. Berries. Lean meat (chicken, fish). Avocados! Apples. Cook with olive oil instead of butter. Try to get more unsaturated fats than you do saturated. (some seafood, like smoked oysters, or things stored in oil in a can, have high saturated fat.)

Avocados are awesome. Nuts and berries are fantastic. Eggs and chicken are great. Yogurt is awesome, it really is a helpful food, no doubt. Try to limit your milk, cheese to some degree.
