Signs of Nutritional Deficiency


Our bodies need an adequate amount of nutrition to stay healthy and function optimally. You get this nutrition from macronutrients such as fats, carbohydrates, and proteins, while micronutrients such as vitamins, minerals, and amino acids also play an important role in maintaining good health. These micronutrients are not produced naturally by the body, so you must get them through your diet.

When the body does not get enough nutrition or is unable to absorb the required amount of nutrients properly, it results in a condition known as a nutritional deficiency. This can lead to various health problems and diseases, such as digestive diseases, skin diseases, improper bone development, and dementia.
