The Importance Of Nutrition For Your Overall Physical And Mental Health

The scientific evidence is very clear on this: we can certainly manage our own health through the things we eat daily.

Did you know that scientists are currently investigating ways to protect astronauts from radiation through dietary supplements? Radiation hazards in outer space pose a huge safety hazard to astronauts, causing the formation of free radicals. Thanks to special nutrition, however, astronauts are able to counter the effects of these free radicals.

The same principle applies to us “normal” humans. Free radicals form throughout our bodies due to all kinds of environmental attacks. It’s a good thing that nowadays more and more people are noticing and changing their lifestyle in order to reap the benefits of healthy eating and exercise.

If a healthy body and mind is what you want, understanding nutrition is of utmost importance. In her infinite wisdom, nature has provided us with everything we need to promote growth, the immune system, mental alertness, physical strength, etc. Without a basic understanding of nutrition, it will be very difficult, if not impossible, to establish a diet that includes the necessary elements that the body needs.

What exactly is understanding nutrition?

To put it simply: everything you ingest has an influence on your body. You must therefore ensure that what you eat contains the elements that your body needs. What your body needs are carbohydrates, fats, proteins and last but not least water. The amount in which each of these elements is consumed greatly influences how you feel, react and age.

1. Carbohydrates – this is the body’s number one source of energy. Our liver and the muscles in our body need an adequate intake of carbohydrates to stay healthy. You can find two main types of carbs (or carbs as some people prefer to call them):

– simple carbohydrates, which are mostly sweet in nature (eg fructose, sucrose, glucose, etc.) and

– complex carbohydrates, which are starch-based (found in corn, brown rice, wheat, etc.).

2. Fat – should be taken in sufficient amounts to moderate metabolism and protect vital organs. Too much fat in your daily diet, however, has the opposite effect. The two main fats are

– cholesterol: you can get cholesterol from seafood, eggs, dairy products and meat.

– Triglycerides: saturated, poly-saturated and mono-saturated fats, they have an influence on your weight and your heart function.

3. Protein – Without protein, the body cannot grow or repair itself. Non-essential amino acids are made by the body itself (hence the term non-essential, the body can supply its own) while essential amino acids should be brought into the body by consuming the right foods.

4. Water – the body needs plenty of water: at least eight glasses a day. This amount helps the body to expel toxins, fight dehydration, prevent heatstroke, moderate body temperature, digestion and so many other functions. We all know that humans can go without food for up to three weeks; however, they will perish without water in as little as 48 hours.

The right kind of wall-balanced nutrition contributes directly to the health of individuals and communities. Clinical research as well as evidence gathered through laboratory testing and field work confirms the concept’s importance to the practice of clinical medicine, dentistry and public health.
