Eating a healthy food does not only provide energy and stamina which is good for the body. However, you also should be wise in choosing foods that can make the body is always ideal.

If you’ve been less paid attention in choosing healthy foods, then it’s time to start learning what foods that the body needs.

To find out, you could follow this lists which is taken from Yahoo:

Green vegetables

Medical experts say, green vegetables is one of the wonders of natural food. Green leafy vegetables are rich in nutrients such as folic acid and vitamins A and C, which can reduce the risk of cancer. With one cup of dark green leaves per day, you can prevent the possibility of diabetes and hypertension.

Nuts

Many nutritionists recommend nuts such as almonds, cashews, and walnuts for high natural fiber content. Fiber slows the digestive process, keeping hunger, and could be a snack in the afternoon.

Onion

Studies show that eating garlic regularly can reduce asthma symptoms and the risk of stomach cancer. Add onion to the soup and stir your dish, will provide greater health benefits for families.

Whole grains

Refined grains like white rice and pasta have lost 90 percent of the nutritional value through the distillation process. But, as if this is not enough reason for you to move selected grains such as brown rice, quinoa, and whole grains as your daily food and family.

Recently, a study showed that a diet rich in oats can actually reduce the fat stored in the lower abdomen. So do not be surprised if a lot of people eat brown rice or wheat, but still has a lean and flat stomach.

Yogurt

Incorporate yogurt into food to accompany your routine daily can improve your digestion. Of course, if you eat the right way. Check the list of labels, if there are labels “active cultures” to ensure you get healthy probiotics.

Choosing a probiotic yogurt rich in vitamin D also is one of the efforts to prevent osteoporosis.

People with high blood pressure (hypertension) should be smart in choosing their meal. The two main foods that can affect hypertension is salt or sodium intake and potassium intake.

But there are ways diet can be done for patients with hypertension which is the DASH diet (Dietary Approaches to Stop Hypertension).

The diets was developed in the United States but has been successfully used in nations around the world such as  South Africa.

Just so you know, South Africa in general, and the African population in particular, are vulnerable to hypertension or high blood pressure.

An estimated 24.4 percent of adults in South Africa suffer from hypertension. Consequently, many of which had a stroke and brain damage in this population. Salt intake and high potassium is the main cause.

Whereas the WHO recommends a ratio of sodium to potassium in the diet is 1:1. But in Africa, the consumption of sodium are very high which could reach 8 grams / day (compared with the recommended maximum of 6 grams / day). While in the other hand the consumption of potassium are very low (50-60 mmol / day). This is what causes many people to suffer high blood pressure in South Africa.

Studies conducted by Professor Karen Charlton and his team in 2007 at the University of Cape Town and Medical Research Council in Cape Town, the DASH diet achieved promising results in 80 patients with a mild to moderate hypertension who received antihypertensive medication. Only by changing the six items of food in their diet for eight weeks.

DASH diet has provided scientific evidence that eating lots of fruits, vegetables and whole grains with a low-fat milk or fat-free, can increase potassium, magnesium and calcium intake. While reducing sodium intake to a level acceptable to reduce blood pressure.

Prof. harlton provided bread, margarine, broth, soup mix and a sense amplifier with less sodium or salt content and Maas 500 ml per day (not seasoned sour cream) for the 40 ‘candidates’ for a period of eight weeks.

Another 40 people classified as ‘control subjects’ are given the same diet with normal content of salt and 500 ml of cold sweet drinks for the same period.

After eight weeks, systolic blood pressure an average of 6.2 candidates mm Hg lower than control subjects. Whereas systolic blood pressure and diastolic BP control subjects as measured by ambulatory blood pressure monitoring 24-hour average above 4.5 mm Hg lower than testing participants.

In thegroup participants sodium intake test did not change, whereas participants in the control group increased by almost 1 gram per day.

Nutritional intake increased dramatically. Calcium intake increased almost double, potassium intake was almost 900 mg per day and magnesium intake increased by 84 mg per day in the test group.

Please note that the increased intake of potassium, calcium and magnesium is achieved without the use of mineral supplements.

Prof. Charlton and his team (2007) concluded that their research showed the public health response.

“You can achieve reduction in systolic blood pressure is clinically significant for the treatment of hypertension is low-income communities in South Africa through the manipulation of the seven dietary intake of processed foods,” he said.

This study not only indicates that the poor with few resources can make dietary changes that can increase blood pressure, but the eating habit can be changed by making some adjustments.

Have you ever heard of Li Qing Yuen? He’s the person who lived up to a ripe old age of 252 years. No kidding. The life (and longevity) of Prof. Li Qing Yuen, who lived between 1678-1930, is one of the best documented. And you know what? He’s reported to have consumed Goji berries daily!

Goji berry is a member of the wolfberry family and is known by the scientific name of Lycium barbarum. It’s credited with increasing the life span and having several health improving properties. It is one of the richest natural nutrients available on earth. It is said that the Chinese have been using Goji berry, as a food and a medicine, for more than five thousand years.

Nutritional value of Goji Berries

Goji berry is a rich source of nutrients and amino acids. It contains 18 amino acids, 21 trace minerals and several vitamins and minerals. It has six times more amino acids than bee pollen, 500 times more Vitamin C by weight than oranges, more iron than spinach, and more Beta carotene than carrots. Goji berry contains minerals like Calcium and Magnesium, and Vitamins B1, B2, B6 and Vitamin E, normally found in grains and seeds and rarely in fruits. In addition, these berries contain many complex compounds and phytonutrients. High levels of protein content (13% of these berries are protein – higher than whole wheat), and antioxidants are other nutrient highlights. In addition, Goji berries contain Beta-sitosterol, Betaine, and essential fatty acids. With all this nutrition packed into it, it is small wonder that these berries have a great medicinal and health value.

Benefits of Goji Berries

Goji berries have been used in traditional systems of medicine to treat various conditions like anemia, cough and inflammation. It has also been used for improving the immune system, protection of the liver, and improving eyesight. Apart from the curative properties, Goji berry is believed to have a positive effect on the health and wellness of those consuming it, and benefits the user with longevity, increased vitality and sexual prowess.

Elderly patients, who were given Goji berries thrice a week, reported several benefits, including improved sleep, better appetite and recovery of sexual function in some cases.

Antioxidants combat free radicals, which are responsible for damaging cells and DNA, increasing the risk of cancer and aiding the ageing process. The high level of antioxidants in Goji berries ensures that the ageing process is slowed down. It is believed that Goji berries have contributed to the freedom from diseases like diabetes, high blood pressure, heart diseases, stroke, and Alzheimer’s disease in the people of Asia who have been consuming this fruit.

About the plant

Goji berry grows in protected valleys with vines reaching up to heights of 4 m. The plant grows in sandy or clay soil conditions under semi shade or no shade. The fruits are never plucked by hand since they are very sensitive and can be spoilt if they are touched by hand at this stage. Instead the fruits are shaken on to a mat and then dried in the shade.

Dosage and consumption details

Goji berries taste somewhat like raisins. They can be taken alone or mixed with other ingredients. Daily dosage could be about 10-30 grams.

The best way to take dried Goji berries is to wash them in water and soak them for a short while, before consuming. You can get it at reasonable prices at most Chinese stores.

Potassium represents 5% percent of the total mineral content of a human body, even though only about one litre is found in the body at a time. Potassium is found in our bodies both inside and outside cells and is a very important mineral required every day to stay healthy. More than 98% of the body’s potassium is intracellular. The body easily absorbs potassium, but nearly 90% of it is excreted through the kidneys and bowels. Thus, potassium is a natural diuretic and is important for the elimination of body wastes, such as water and sodium.

Potassium is a primary electrolyte, it is a great alkalizer, and important for maintaining pH and water balance.

Benefits of potassium:

1. Along with other minerals such as sodium, chloride and calcium, potassium helps in normal cellular function, such as transmission of nerve impulses, digestion, healthy muscle contractions, proper cardiovascular functioning (heartbeat irregularities are normally a sign of potassium deficiency), and helping the body to convert glucose into glycogen (the body’s stored form of energy).

2. Potassium helps promote healthy cardiovascular health. It is strongly believed that potassium has the ability to pump sodium out of the body’s cells and reduce body fluid.

3. Potassium, along with sodium, helps to regulate blood pressure. Increasing potassium in the diet may protect against hypertension in people who are sensitive to high levels of sodium.

4. Potassium also affects blood vessel tone as well as the way blood vessels react to the flowing hormones, thus affecting pressure within blood vessels.

5. Potassium therapeutically assists in the treatment of alcoholism, acne, alleviating allergies, promoting the early healing of burns.

6. It also helps with problems such as congestive heart failure, chronic fatigue syndrome or kidney stones.

7. Potassium plays a vital role in cellular integrity by regulating the transfer of nutrients into the cell.

8. Potassium also attracts oxygen to tissues, helps correct positioning of vital organs. Potassium deficiency indicates that probably albumin, sugar, sodium, and chlorine are also in short supply or not being properly absorbed.

9. Potassium helps proper functioning of the adrenal glands. It helps support healthy sugar balance in the body.

Deficiency of potassium –

The kidneys excrete excess potassium from the body, and deficiencies are rarely found in people on a normal balanced diet. A deficiency may result in fatigue, cramping legs, muscle weakness, sluggish reflexes, acne, dry skin, mood swings and irregular heartbeat.

A shortage of potassium in body may cause a fatal condition known as hypokalemia, resulting from diarrhea, increased diuresis and vomiting. Hypokalemia can occur in people with a chronic disease or due to aging process. Deficiency symptoms include muscle weakness, ECG abnormalities, decreased reflex response, congestive heart failure, cardiac arrhythmia and respiratory paralysis.

If the fluid and electrolyte balance is not restored, the risk of heart failure increases.

Potassium deficiency increases acid levels in the body, lowers the natural pH balance, causes problems with the formation of connective tissue. Kidney diseases (such as acute renal failure), diabetes can also cause fluctuations in the levels of potassium. Many medications such as diuretics, cortisone, prolonged use of aspirin, and laxatives also cause depletion of potassium.

Dietary sources of potassium:

Eating a variety of foods that contain potassium is the best way to get the required amount. Individuals who eat a balanced diet do not need potassium supplements. Foods, which are rich sources of potassium include turnips, whole grains, molasses, fish, citrus fruit, apple cider vinegar, bananas, avocados, yoghurt, tomatoes, poultry, oranges, apricots, potatoes (especially their skins), leafy green vegetables such as spinach, lettuce; and meat. One large orange will supply one with 250 mg of potassium, one-eighth of a person’s daily need. Dried apricots contain more potassium than fresh apricots.

Steaming of foods helps to retain nutrients that are lost through other cooking techniques such as boiling (loss of about 50% of potassium content). Steaming results in only a 6% loss of potassium.

Recommended Daily Allowance of potassium:

There is no recommended daily allowance (RDA) for potassium, but it is advised to get between 2,000-3,000 mg per day. The range of intake for children is 780 to 1,600 mg per day.

This is not difficult, and most people meet this requirement on their own through a normal diet. In general, nutritionists recommend reducing salt intake and ensuring adequate supply by increasing the amount of fresh fruit and vegetables in the diet.

If one is into bodybuilding, he must increase the potassium intake, since potassium is needed to maintain muscles in good form, and also because potassium is lost from excessive sweating and urine.

Symptoms of high intake of potassium:

Excessive potassium can be toxic and will affect the heart. This is a problem especially when one is suffering from some problem such as kidney failure. Irregular heart beat and muscle fatigue is sign of toxic potassium levels. In healthy people, the kidneys in the urine excrete excess potassium.

Who requires extra potassium?

People who require potassium supplements include:

# women on oral contraceptives,

# chronic alcoholics or drug abusers,

# smokers

# people undergoing stress

# athletes

# people doing strenuous exertion,

# anyone suffering from any degree of mal-absorption syndrome

# people with eating disorders, especially bulimia and anorexia..

There are lot of foods which may increase fertility in men who are trying to get a woman pregnant. Each has exacting nutrients known to help the body create more sperm. Popular examples include oysters, because their high level of zinc increases testosterone and semen making; clams and liver, both of which contain good amounts of vitamin B-12; whole grains, legumes and leafy green vegetables, known for their vitamin E content; and vitamin C-rich foods such as oranges and limes.

If your wife are trying to get pregnant, you’ll need to increase your sperm cell health. You can start by doing several things that have been proven to increase fertility and sperm count. Simple things like wearing looser clothing can lower the hotness around your testes, as heat is one thing that is well known to slow down sperm making.

Eat a diet that includes whole, natural foods. The best foods for health in general and also for sperm count problems, are whole grains, legumes, vegetables, fruits, nuts, and seeds.

Drinking more water and eating more “sperm friendly” foods are a good start in creating healthier sperm. For quicker and more noticeable results, clinically formulated sperm pills are an excellent option for raising sperm count, increasing semen volume, improving sperm motility, and promoting sperm health.

Asparagus, snow peas, cooked tomatoes, strawberries. The vitamins C in these foods affect sperm motility and viability. Vitamin C and vitamin A are found in many of the same foods: kale, red peppers, sweet potatoes, yellow veggies and fruits.

Eating eggs can not only help increase sperm count and but it can also improve the chances of fertilization. Eggs are in high in vitamin E, an ongoing deficiency of which has been linked to testicular tissue degeneration. The antioxidant quality of vitamin E can help to offset the negative effects that free radicals have on our body’s cells, including sperm.

Natural Nutritional Supplements
There are also a variety of vitamin supplements that may assist with low sperm count, like
* Vitamin C
*Zinc Arginine
*Carnitine
*Vitamin E
*Vitamin B12

Whole grain foods such as bread, cereal and crackers can increase your chromium levels, thereby growing your sperm count. In a text review of studies of the effects of chromium, the journal “Biological Trace Element Research” found that many studies indicate low chromium levels are correlated with decreased sperm count.

Zinc is vital for viable sperm count, motility and a high percentage of live sperm in the semen. Zinc is present in semen and therefore men can lose too much quantities of zinc through ejaculation – therefore it is critical that zinc is replaced through the diet daily. Foods rich in zinc such as lambs, turkeys, barleys, wheat, oysters, beans, nuts, red meats, raw sunflower and pumpkin seeds are considered to be the super-foods that can help to increase the sperm count in men.

Vegetables including broccoli, spinach, mustard, and other green vegetables help increase your sperm count significantly. Tomato also contains a lot of antioxidants that help increase sperm productivity. Zinc, selenium and chromium also help produce more sperm in men.
