Figure 3. The Food Pyramid |
(1) A balanced diet To be healthy, we need to maintain a balanced diet that provides a variety of nutrients -- protein, carbohydrates, fats, minerals, vitamins, and water. The food pyramid (Fig. 3), suggests the appropriate variety and amount of foods. It is divided into four layers. From the bottom to the vertex of the pyramid, it starts with breads, cereal and rice group(carbohydrate), next, it is the vegetable group and fruit group, then it is milk, yogurt and cheese group, and the meat, poultry, fish, dry beans, eggs and nut group; lastly, it is fats, oils and sweets group. If we ingest too much or too little of particular nutrients, it can lead to malnutrition and illness, e.g. coronary heart disease. (2) Avoid stimulants There are certain food substances that can produce a stressful response, for example, cola, coffee, tea, chocolate and nicotine in tobacco. They contain caffeine that increases metabolism, the release of stress hormones, heart rate and blood pressure. They also raise one's alertness, too. (3) More vitamins B & C When we are under stress, a great amount of vitamins B and C is released. The depletion of vitamins B and C leads to anxiety, depression, stomach upset, muscular weakness and insomnia. Also, it reduces the production of adrenal cortex and hence lowering our ability to deal with stress. To prevent deficiency in vitamins B and C, we have to intake more cereals, green leafy vegetables, liver, or fish as well as more citrus fruits, tomatoes, cabbages and potatoes respectively.
(4) More calcium Stress can affect the absorption of calcium in the intensine and can increase the excretion of calcium, potassium, zinc, copper and magnesium. This may led to fragile bones and increase the risk of fracture, especially in women. (5) Less salt Salt is another stressor. If one is genetically susceptible to sodium and he/she continues to ingest too much of it, high blood pressure develops easily. When the individual is confronted with stressors, the blood pressure may be further elevated to a dangerous level. (6) Less sugar Sugar can lead to stress, too. In order to break down sugar, sufficient amount of vitamin B is needed. However, a great deal of vitamin B is released when we are dealing with stress. Therefore, it is advisable to eat less sugar, especially processed flour, in order to reduce the amount of vitamin B needed in breaking down sugar. Hence we can have sufficient amount of vitamin B in response to stressors. (7) Weight control Obesity increases the risk of uterine, cervical, and breast cancers in women. Therefore, it is desirable to control our weight. However, an overemphasis on dieting is unhealthy because anorexia nervosa and bulimia may result. It is advisable to be more realistic about our weight, pay more attention on health first, follow the instruction of professional physician, and do exercise regularly. (8) Eating rhythm and atmosphere Apart from food, eating slowly is equally important. Intemperate eating affects digestion and excretion. Try to take a walk, read a book, listen to music or take a rest before having a meal. Keep a delighted atmosphere during eating and eat slowly. All these can make us enjoy our meal, reduce stress, and avoid ulcers. |
