Nutrition also focuses on how people can use dietary choices to reduce the risk of disease, what happens if a person has too much or too little of a nutrient, and how allergies work.
Nutrients provide nourishment. Proteins, carbohydrates, fat, vitamins, minerals, fibre, and water are all nutrients. If people do not have the right balance of nutrients in their diet, their risk of developing certain health conditions increases.
This article will explain the different nutrients a person needs and why. It will also look at the role of the dietitian and the nutritionist.
Nutrition Facts Macronutrients are nutrients that people need in relatively large quantities.
Sugar, starch, and fibre are types of carbohydrates.
Sugars are simple carbs. The body quickly breaks down and absorbs sugars and processed starch. They can provide rapid energy, but they do not leave a person feeling full. They can also cause a spike in blood sugar levels. Frequent sugar spikes increase the risk of type 2 diabetes and its complications.
Fibre is also a carbohydrate. The body breaks down some types of fiber and uses them for energy; others are metabolized by gut bacteria, while other types pass through the body.
Fibre and unprocessed starch are complex carbs. It takes the body some time to break down and absorb complex carbs. After eating fiber, a person will feel full for longer. Fibre may also reduce the risk of diabetes, cardiovascular disease, and colorectal cancer. Complex carbs are a more healthful choice than sugars and refined carbs.
Proteins consist of amino acids, which are organic compounds that occur naturally.
Some foods provide complete protein, which means they contain all the essential amino acids the body needs. Other foods contain various combinations of amino acids.
Most plant-based foods do not contain complete protein, so a person who follows a vegan diet needs to eat a range of foods throughout the day that provides the essential amino acids.
Fats are essential for:
- lubricating joints
- helping organs produce hormones
- enabling the body to absorb certain vitamins
- reducing inflammation
- preserving brain health
However, the type of fat a person eats makes a difference. Unsaturated fats, such as olive oil, are more healthful than saturated fats, which tend to come from animals.
Many people recommend consuming 2 litres, or 8 glasses, of water a day, but it can also come from dietary sources, such as fruit and vegetables. Adequate hydration will result in pale yellow urine.
Requirements will also depend on an individual’s body size and age, environmental factors, activity levels, health status, and so on.
