If we observe, more than ever most of us are beginning to realize that we are not getting our proper nutrition just from our food and that we need to take vitamins and other nutritional supplements on a regular basis. There might be different reason for this, its may be that we are not getting all the vitamins & mineral form the food we are taking on every day basis. Your daily vitamins play some very important roles within the body. They help strengthen your immune system, slow down the process of aging, and increase your energy levels. When choosing a daily vitamin make sure you know what you need and what you are looking at.
Vitamins are sometimes referred to as the "spark plugs" of our human machine. They are required to do many things and their excess or depletion can lead to acute and chronic disease. This is why understanding the vitamins is important in healthy aging. The vitamins are categorized into two groups:
* water soluble (vitamins B,C, P).
Some Problems with Vitamin Deficiency:
What role do vitamins and minerals play in nutrition?
Vitamins help the body turn food into energy and tissues. There are 13 vitamins in all: vitamin A; the vitamin B complex, which includes thiamine, riboflavin, niacin, vitamin B6, folic acid, vitamin B12 pantothenic acid, and biotin; and vitamins C, D, E, and K.
Minerals are needed for growth and maintenance of body structures. They also help to maintain digestive juices and the fluids found in and around cells.
Unlike vitamins, carbohydrates, fats, and proteins, minerals are not made by plants and animals. Plants get minerals from water or soil, and animals get minerals by eating plants or plant-eating animals. The minerals the body needs in large amounts include calcium, chlorine, magnesium, phosphorus, potassium, sodium, and sulfur. Other minerals, called trace elements, are needed in much smaller amounts. Trace elements include iron, copper, fluorine, iodine, selenium, zinc, chromium, cobalt, manganese, and molybdenum.
Here is a rundown of what each macronutrient does and some good sources.
Carbohydrates Carbohydrates include all starches and sugars. They are the body's main source of energy. Each gram of carbohydrate provides 4 calories. Most foods contain carbohydrates. The main sugar in food is sucrose, which is everyday white or brown sugar. Other sugars include lactose (found in milk) and fructose (found in most fruits and many vegetables). Starches are a more complex form of carbohydrate. They are more filling and contain more nutrients than foods with lots of sugars, fats, or oils. Foods containing starches include beans, breads, cereals, pasta, and potatoes.
Fats Fats pack a lot of energy. Each gram of fat provides 9 calories. There are three kinds of fat: saturated, monounsaturated, and polyunsaturated. Animal and dairy fats, which remain solid at room temperature, are saturated fats. Saturated fat is often called "bad" fat. Unsaturated fats include vegetable fat and oils; they remain liquid at room temperature.
