What is Nutrient Density and Why Is It Important to Eat a Nutrient-rich Diet?

What is Nutrient Density?

This article describes nutrient density, a term used to describe how nutritious a particular food or diet is. It explains how you can make a nutritious diet and identifies the biggest misconceptions about nutrient density. At the simplest level, the more nutrients your body gets from food, the denser the number of nutrients. On the other hand, the less nutrients your body gets, the less nutrients it has.

Nutrient density is formally defined as the amount of nutrients by weight or calories in food. Portion size can also be taken into account. In other words, 100g of fish has 4g of potassium, or 100 kcal of fish has 4g of potassium. But the density of nutrients is more than this simple definition suggests. The fact that there are so many different essential nutrients makes things more complicated. In addition, not only the amount, but also the bioavailability (the amount we can use and absorb) must be considered. In addition, nutrient density is not found in many foods and focuses on important nutrients that many people lack.

Macronutrients and micronutrients

Nutrients are generally divided into macronutrients and micronutrients. Micronutrients are the fuel. They provide energy. Micronutrients ensure that everything goes smoothly. They have a myriad of functions in the body. They are necessary for biochemical reactions to occur and they also have a structural role.

The main nutrients are:

  1. protein
  2. obesity
  3. carbohydrates
  1. The micronutrients are:
  2. amino acid
  3. fatty acid
  4. vitamin
  5. mineral
  6. Fatty acids
  7. Some nutrients function as micronutrients and macronutrients.

There are the building blocks of proteins. It (and proteins) provide energy because they have calories, but they are used primarily as a component to make proteins in the body, not energy production.

It is also important to mention that not all proteins are made the same. Proteins are composed of 20 types of amino acids, 9 of which are essential. Essential amino acids cannot be produced, so you need to get enough from your diet. Foods that provide all nine essential amino acids are a complete source of protein. A typical example is an egg that provides all the essential amino acids in the ideal proportions. Can absorb and digest 97% of egg protein

Vegetable foods may also contain a decent amount of protein, but the quality of the protein is much lower because it doesn’t provide all the essential amino acids in the right amount. For example, it absorbs only 64% of wheat gluten [3].

Fatty acid

Fat, on the other hand, is primarily a fuel, but has additional functionality. Among other functions, fatty acids are required to build cell membranes and hormones [4] [5]. Docosahexaenoic acid (DHA) from long-chain omega-3 fatty acids and arachidonic acid (AA) from omega-6 fatty acids are essential fats we need to get from food [6] [7].

Vitamins and minerals

Vitamins and minerals are like tools that support all physiological processes. They are essential for metabolic processes, tissue function, immune function, blood coagulation, etc. [8].

Fat-soluble vitamins and water-soluble vitamins

Vitamins are generally divided into fat-soluble vitamins and water-soluble vitamins for stable fitness. Fat-soluble vitamins include vitamins A, D, E, and K. Water-soluble vitamins include vitamin B and vitamin C.

You also need to get choline from your diet. It’s not a vitamin, but it’s a lot like a vitamin.

Macrominerals and trace minerals

Macrominerals contain relatively large amounts of required minerals such as magnesium, calcium, potassium and sodium. The required trace minerals are usually in the range of micrograms (µg) or up to a few milligrams (mg). Above all, iron, zinc, copper and iodine are trace minerals.

Nutrient density vs. Calorie density

Nutrient density generally refers to micronutrient density. Foods that are high in calories (major nutrients) but not high in micronutrients are considered high in calories but low in nutrients. Fat-rich foods are often considered low in nutrients (compared to calorie content) because fat provides about twice as many calories per gram as protein and carbohydrates.
