Key nutrients

All nutrient guides
Trans Fat: foods to watchTrans fat is mostly a byproduct of partially hydrogenated oils used in processed food. It offers no nutritional benefit, so keeping intake as close to zero as possible is the goal.
Foods high in Omega-6 (Linoleic Acid)Linoleic acid is the essential omega-6 fat most common in the diet, found abundantly in vegetable oils and nuts.
Sodium: foods to watchSodium helps regulate fluid balance and nerve signaling, but most diets already get plenty from processed and restaurant food. Keeping intake moderate matters more than adding it.
