Hello fitness enthusiasts! How are you doing on this fine Friday? Have you ever heard the term “You are what you eat” and just shrugged it off? Well, I am here to tell you that you are totally what you eat. Today’s subject shall be about nutrition and what the it is. This will be a collaborative effort with my good friend Wikipedia giving us some history. Say, “Hi” Wiki.
Nutrition is still in its scientific infancy. The most recent form of proper nutrition is about a hundred years old and still being heavily inspected and tweaked as to what is proper, but nutrition has always be around in some way shape or form since as far back as 2500 BC with some talk about not eating onions for three days if you had stomach pains. I kid you not, there was a stone tablet that actually said that in some manner. Crazy, I know. The vitamin C deficiency that causes scurvy was discovered in around 1500 BC, although it wasn’t proved with modern science until 1932 by Albert Szent-Györgyi. The call for moderation with food and emphasis on exercise came to be around 400 BC with Hippocrates. So, you can see that nutrition has existed for a very long time, but within the last 100 years has gotten pretty scientific.
We could delve deeper into the history of nutrition, but it gets pretty crazy with talk about four elements (earth, wind, water, fire) or hot (meats, blood, spices, etc) and cold (green vegetables) so I won’t get into that. Hey, you! Back over here, pay attention. As I was saying, within the last 100 years nutrition has become very scientific. From 1926 through 1936 all of the major vitamins were isolated and synthesized. During WWII (1941) the first Recommended Daily Allowances were established by the National Research Council. In 1992 we saw the first government designed nutritional food pyramid. Now, in 2015 you can’t view anything on the internet without seeing some form of dietary plan or news article related to health and wellness.
Is it just me or does that actually look delicious?
Nutrition divides everything into two categories: Macronutrients and Micronutrients. Macronutrients are needed in large amounts as compared to micronutrients. Macronutrients consist of carbohydrates, fats, proteins, and water. Micronutrients consist of minerals, vitamins, phytochemicals, and antioxidants. Carbs can be broken down into complex and simple categories. Simple carb digestion begins immediately in the mouth and makes its way into the bloodstream faster for instant short-lived energy. Complex carbs (fiber, dietary fiber being very important) are a bit harder for the body to break down and, therefore, provide a longer lasting source of energy. Fats can be separated into saturated and unsaturated (monounsaturated and polyunsaturated) fats, which are important to the body’s transportation system. Proteins are enzymes and amino acids integral to the maintenance of the human body’s structure (muscle, skin, hair, nails, etc.). Water doesn’t need any further explanation beyond that your body is 60% water and without it we cannot exist. Soda and coffee and all those not so good things all contain water as well as many other chemical components that either provide some benefit or hindrance in some fashion according to some new scientific study
On to micronutrients! These can be divided into several categories. Macrominerals consist of calcium, chlorine as chloride ions, magnesium, phosphorus, potassium, sodium and sulfur. Trace minerals consist of cobalt, copper, chromium, iodine, iron, manganese, molybdenum, nickel, selenium, and zinc. Phytochemicals are chemicals found in plants that can act as antioxidants but not all phytochemicals are antioxidants. Where did everyone go?
