why do we need nutrients in our diet
Why do we need minerals in our diet? In one sentence : Our bodies canБt produce all of the nutrients that we need to function properly, so we have to eat them. To understand why we need to eat minerals, it s best to first understand what minerals are. б Minerals are inorganic substances, which occur naturally in non-living things such as water, rocks and soil, as well as in plants and animals. бб Some minerals are for our cells to function properly, so they are actively taken into plants from the soil and water. б We obtain minerals when they eat plants, as well as from water. What do dietary minerals do? The minerals in our diet are essential for a variety of bodily functions. They are important for building strong bones and teeth, blood, skin, hair, nerve function, muscle and for metabolic processes such as those that turn the food we eat into energy. This means that minerals are needed for the body to work properly, for growth and development, and overall, for
maintaining normal health.
Different minerals are required in different amounts but they are all essential. Minerals are grouped depending on how much they are needed on a daily basis so the minerals that are needed more in bigger amounts on a daily basis are known as the minerals, macro-minerals or major minerals. The minerals that are needed less and in smaller amounts are known as micro-minerals or trace elements. Children, pregnant and breastfeeding mothers and older people may need to adjust their intake depending on the type of mineral. It is also important to note that excessively high intakes of minerals can be toxic (harmful). No nutrient can single-handedly change the way our body or organs work. б б It is balance that brings it all together. б Read about the balance of iron. Did you know? б As few as 20 of the iron tablets, used to treat anaemia, can be enough to kill.
We are always hearing about the importance of nutrients in our diet - that's why we eat fruit and vegetables, take supplements, and buy enriched products. But what exactly are nutrients and how do they help our health? Nutrients are substances used by your body to make energy and to repair itself. They are necessary for the proper working and growth of your body, and they must come from the environment. In other words, you need nutrients for a number of bodily functions and upkeep, and you have to eat nutrients because you can't make them yourself. Nutrients can be used to provide energy, such as carbohydrates, and fats, and they can also be used to support metabolism and the upkeep of your body, such as vitamins and minerals. Although all of us need to ingest water and oxygen to survive, there are not considered nutrients since we do not eat them as food. Nutrients come in organic form (meaning they are taken from living things) and inorganic form (they were never part of a living thing, rather they come from the earth).
Proteins, fats, vitamins, and amino acids are organic nutrients because they are derived from living things like plants, dairy and meats. Minerals are inorganic nutrients because they come from non-living things the earth. Nutrients can also be classified by how much of them you need. Macronutrients are nutrients that your body needs in large quantities for its upkeep, such as the chemical elements carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. These are the elements that humans consume in the largest quantities, because they are the components that make up living things. The minerals calcium, sodium, chloride, magnesium, and potassium are also sometimes called macronutrients because we require them in relatively large quantities compared to other vitamins and minerals.
Together with phosphorus and sulfur, these minerals are also sometimes called macrominerals. Eamples of organic macronutrients (as opposed to the inorganic macronutrients discussed so far) are the chemical compounds that we use for energy: fats, proteins and carbohydrates. In comparison to macronutrients, micronutrients are all other vitamins and minerals that we need to consume to stay healthy, but not in near as large quantities as the macronutrients. One more classification used on nutrients is whether they are essential or inessential. Essential nutrients are those which our bodies can't make themselves. Therefore we must get them thorugh what we consume (our food). Essential nutrients to human are essential fatty acids, essential amino acids, vitamins, and certain dietary minerals. Inessential nutrients are those our bodies can synthesize themselves, using the essential nutrients.
