General Health
Modern life is hectic. Whether they realise it or not, most people are multi-tasking by juggling home, career and personal life, all at the same time. Some manage it better; others are simply left struggling from day to day in an endless cycle.
On top of the daily routine, there are other pressures associated with modern living, such as traffic jams, societal expectations and responsibilities at work or home. All these and more add stress and pressure to people in the 21st century.
All these and more makes it necessary for us to stay fit and healthy in order to face the challenges of modern living. Having energy and stamina keeps us positive and focused on our goals and direction, thus allowing us to love our lives to the fullest.
A balanced diet with ample exercise is the best balance for a healthy lifestyle. Unfortunately many people find it an uphill task achieving one, if not both.
Vitamin or mineral deficiencies may not have obvious manifestations. If you have been feeling tired, depressed or unable to cope, speak to your doctor or pharmacist whether you need additional nourishment, whether with whole foods or nutritional supplements.
Vitamins and minerals for a healthy body
Vitamins are organic substances that your body needs to grow and develop normally. Each vitamin has a specific function. Low levels of certain vitamins can cause certain diseases, such as rickets which is caused by vitamin D deficiency and beri beri which is caused by deficiency in Vitamin B1.
Vitamins can be divided into two categories: fat soluble and water soluble. The fat soluble vitamins are vitamin A, D, E and K. Fat-soluble vitamins are stored in the fat reserves of the body.
Water soluble vitamins are vitamins C and the B-complex, which are dissolved in body liquid before our bodies can absorb them. These vitamins are not stored in the body and will be passed out of the body through urine if they are not utilised by our bodies. As such, it is important to have continous supply of water-soluble vitamins in our bodies at any at any one time.
Minerals, on the other hand, are inorganic elements that come from the soil and water that are absorbed by plants or eaten by animals. Our body needs relatively large amounts of macronutrients such as calcium, phosphorus, sodium, potassium, chlorine, magnesium and sulfur to function well.
Other minerals like chromium, copper, iodine, iron, selenium, and zinc are called trace minerals because we only need very small amounts of them each day.
Most vitamins and minerals are taken according to the United States Recommended Dietary Allowance (US RDA). The RDA is simply a set of guidelines of nutritional recommendations, stating the number of servings for each food group. Developed during the WW2 by the United States National Academy of Sciences, the RDA is now revised every five to ten years to suit changing trends and keep up with advancements in nutrition research.
