Recently, in modern life, people have become so aware of deteriorating health due to numerous factors such as stress and an unbalanced diet that they have been cautiously looking for the most efficient methods to enjoy good health.
While there seem to be so many ways, a balanced diet and regular exercise are of paramount importance to human well-being and definitely two of the most reliable methods for people to keep fit.
A well-balanced diet means a diet including a rich intake of healthy foods such as whole grains, vegetables and fruits and a smaller intake of foods with a high proportion of calories such as fast foods or processed foods.
If you can enjoy such diet, you can maintain a healthy weight, keep your midsection from getting larger and prevent various serious diet-related dieses such as high blood pressure, diabetes or heart attacks. Remember that your life expectancy is in inverse proportion with your waistline.
Small inadequacies of some nutrients could damage the function of the immune system. A healthy diet makes sure that nutrients which are needed for the proper operation of the immune system are sufficient.
As revealed by David Katz, M.D., M.P.H., director of Yale Prevention Research Center, nutrients are essential for the immune system's ability to steadily create bacterium-fighting cells. Moreover, the diet also profoundly affects vascular function and the immune system operates dependently on blood flow.
Only when provided with sufficient nutrients can human body have the energy to maintain effective physical and mental activities throughout the day. Good carbohydrates in whole grains, fruits and vegetables help maintain blood sugar and insulin level for a stable provision of energy.
Healthy proteins in meats, fish, tofu, beans and nuts are also essential for the preservation of energy.
Doing exercise on a regular basis is the key to wellness because it does wonders for both human physical and mental fitness.
Regular exercise makes your bones, muscles and joints stronger. Older adults who suffer from back pain also benefit a lot from doing exercise every day. Conforming to a regular exercise plan strengthens your lung, providing all your tissues with a larger amount of oxygen and nutrients. This oxygen increase makes you more strong and energetic.
Like a balanced diet, regular moderate exercise helps the immune system function more efficiently. Protective cells also known as infection fighters like Natural Killer Cells, white blood cells, and other antibodies can help human body get rid of foreign invaders.
Exercise enhances our human natural immune system by spreading the defensive cells all over the body more quickly, to eradicate more bacteria, viruses and fungi, thus preventing diseases like flu, fever or even lethal ones such as cancer or HIV/AIDS.
Exercise is beneficial to your your mental or psychological health because of its ability to lower the stress level.
After exercising, you feel more relaxed and happier because it stimulates numerous chemicals in your brain, hence helping brain cells function and blood circulate more effectively, which lessens anxiety and depression. Moreover, exercise also helps you to have a nice body; as a result, you become more self-confident.
To conclude, exercise and a balanced diet are of equal importance to human wellness and complimentary to each other. If a person only exercises without a balanced diet, he can become exhausted due to inadequate energy and nutrients. Nevertheless, if he only has a good diet without exercising, he cannot withstand rough circumstances which demand physical strength. Therefore, the best course of action is to wisely and moderately combine these two methods in order to enjoy good health both physically and mentally.
