What are nutrients and what means nutrient density? In a healthy diet optimal would be to get as most nutrient dense food as possible. Meaning simple more nutrients for less calories.
You can think 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 way to eat.
I´m sure you have heard some one talking about micros and macros or if not, let me shortly explain to you.
I´m 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 large amounts in the body. Water is also macronutrient, as we need water a lot, but unlike other macronutrient, water doesn't provide energy.
Vitamins and minerals do not either provide energy and 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.
Body can produce some of the nutritiens on its own and some of the nutritiens 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.
If you are curious to read more, I tried to explain simple and shortly, without using difficult terms what are these "micros and macros" that we daily need.
