Learn basic facts about nutrition to help you in your diet program and protect you against fat diseases.
What’s an essential nutrient?
A reasonable person may assume that an essential nutrient is one you need to sustain a healthy body. But who says a reasonable person thinks like a nutritionist? In nutrition speak, an essential nutrient is a very special thing:
An essential nutrient cannot be manufactured in the body. You have to get essential nutrients from food or from a nutritional supplement.
An essential nutrient is linked to a specific deficiency disease. For example, people who go without protein for extended periods of time develop the protein-deficiency disease kwashiorkor. People who don’t get enough vitamin C develop the vitamin C–deficiency disease scurvy. A diet rich in the essential nutrient cures the deficiency disease, but you need the proper nutrient. In other words, you can’t cure a protein deficiency .
with extra amounts of vitamin C. Not all nutrients are essential for all species of animals. For example, vitamin C is an essential nutrient for human beings but not for dogs. A dog’s body makes the vitamin C it needs. Check out the list of nutrients on a can or bag of dog food. See? No C. The dog already has the C it sorry, he or she requires.
Essential nutrients for human beings include many well-known vitamins and minerals, several amino acids (the so-called building blocks of proteins),and at least two fatty acids.
Protecting the nutrients in your food
Identifying nutrients is one thing. Making sure you get them into your body is another. Here, the essential idea is to keep nutritious food nutritious by preserving and protecting its components.
Some people see the term food processing as a nutritional dirty word. Or words. They’re wrong. Without food processing and preservatives, you and I would still be forced to gather (or kill) our food each morning and down it fast before it spoiled. For more about which processing and preservative techniques produce the safest, most nutritious and yes, delicious dinners.
Considering how vital food preservation can be, you may want to think about when you last heard a rousing cheer for the anonymous cook who first noticed that salting or pickling food could extend food’s shelf life.
