The definition of a nutrient is that it’s something your body has to have, and eventually without it you’d die. Therefore there is no such thing as a “good” or “bad” nutrient because we have to have them all. We are going to spend the next 3 days looking at the macronutrients: carbohydrates, protein, fat.
Carbs are your body’s favorite source of fuel. Ideally, 50-60% of your total daily caloric intake should be coming from carbs.
Things carbs do for your body:
- Protein sparing (they prevent your body from eating its muscles and organs for energy)
- The ONLY source of energy that your brain can use. It needs a continual supply since it can’t store any glucose.
- Increase the serotonin (“feel good” chemical in your brain)
Tomorrow we'll discuss protein.
