What are nutrients and what is nutrient density? In a healthy diet optimal would be to get as most nutrient dense food as possible. Meaning adding more nutrients for fewer calories. You can think the food is more nutrient dense when the level of nutrients is high in relationship to the number of calories the food contains. Got it? Great! Eating nutrient dense food is probably one of the healthiest ways to eat.
We are sure that you have heard someone talking about micros and macros or if not, let us shortly explain to you. We are talking about nutrients called protein, carbohydrates, lipids, water, vitamins, and minerals. First three provides energy and are called energy yielding nutrients. These are macronutrients because we need protein, carbs, and lipids in large amounts in the body. Water is also macronutrient, as we need water a lot, but unlike other macro nutrients, water doesn't provide energy. Vitamins and minerals do not either provide energy, and the body only needs them small amounts, that's why they are called micro nutrients.
Together they provide energy; also they are building blocks for growth and maintenance of a healthy body. The body can produce some of the nutrients on its own and some of the nutrients we must get from our diet. Depending on many different variables like sex, size, health, illness, pregnancy, breastfeeding medication, your daily need of essential nutrients can variate. We tried to explain simple and short, without using complicated terms what are "micros and macros" that we daily need.
