• It is a powerful antioxidant and helps reduce the number of free radicals in your body. This means that it slows down aging and prevents diseases like cancer. A study conducted by the Natural Sciences and Engineering Research Council of Canada and the Ontario Ministry of Innovation has found that garlic is very effective in trapping free radicals because of the allicin it contains. This compound contains sulfenic acid which reacts very quickly with free radicals to “trap” them and so prevent them from causing cancerous tumors. While onions and shallots are rich in allicin too, they don’t have the same antioxidant properties that garlic does because they have a lower level of sulfenic acid, leading to a slower reaction rate with free radicals.
• It is good in controlling your healthy cholesterol levels – garlic brings down the level of bad cholesterol in your blood.
• It is a great natural antibiotic that protects you from a host of illnesses. And the best part is that because it is natural, your body does not build a resistance to it like it does to other antibiotics.
• It lowers your blood pressure and prevents strokes and heart attacks.
• Because it is a natural anticoagulant, it reduces the risk of blood clots that could lead to coronary disease and cardiac arrests.
• It boosts your immune system and destroys bacteria and virus that cause infections and diseases.
• Eating one or two cloves when you have a cold helps reduce the symptoms of this nagging illness.
• Garlic blocks cancer-causing compounds and prevents them from forming tumors in our body. It also slows the growth of tumor cells.

Garlic is best when the sulfur content is high; you could eat it in the raw form or use it to season food by crushing or dicing it into tiny pieces. A word of caution to the overeager – eating too much garlic in the raw form could irritate and even damage your digestive tract because it is very strong. Also, it’s best to consult your doctor and check if you can eat foods that contain garlic a day or two before a surgery because this herb could disrupt your anticoagulant and cause your blood to clot.

They are so packed with vitamins and minerals and many other nutrients that come with astounding health benefits, that they are sometimes labelled ‘superfoods’. There’re many such ‘superfoods’, but they have one thing in common: they are unprocessed, ‘real’ food.

Superfoods include oats, beans, nuts, carrots, broccoli, spinach, tomatoes, strawberries, mushrooms, salmon, soybeans, and yogurt, among many others. We discuss four of these superfoods here.

Garlic

Garlic’s health and medicinal properties have been known for a very long time. It is used widely in alternative medicine. Studies show that it may be a natural antibiotic.

Garlic is rich in vitamin C, an important antioxidant. It is a good source of selenium, which helps prevent cancer and is also a potent antioxidant. It contains manganese which is needed for fertility, strong bones, healthy nerves, and brain function. It is also a source of vitamin B6, which reduces the risk of heart disease and is used for production of red blood cells, and antibodies that help the immune system to fight off diseases. Vitamin C, manganese, and selenium are also good for lowering cholesterol levels.

In general, the stronger tasting a clove of garlic is, the higher the sulphur content and, it is believed, the higher the medicinal value. Organic garlic is said to have a higher sulphur content. People who want to avoid ‘garlic breath’ might opt for garlic supplements instead.

Broccoli

Broccoli is considered by some people to be the ultimate superfood. It is probably best known for its protection against cancer, especially cancers of the lung, breast, stomach, ovary, bladder, colon, and prostate. Like the other cruciferous vegetables, broccoli contains certain phytonutrients that have significant anti-cancer properties. These have been shown not only to inhibit the growth of cancer cells, but also its spread to other parts of the body.

Broccoli contains cysteine which detoxifies chemicals and heavy metals from the body, helping to ease flu and cold symptoms. It is high in fiber, which prevents constipation. It provides zinc and selenium, trace minerals that are needed by the body’s immune system. Broccoli is one of the vegetables that help reduce the risk of heart disease.

It is rich in vitamin C, and in the powerful antioxidants lutein and zeaxanthin belonging to the carotenoid family, that protect cells against free radicals. It has been found to lower the incidence of cataracts significantly.

Broccoli is not only rich in vitamin C (one cup of cooked broccoli contains the full RDA), but it is also high in beta-carotene, which boosts the immune system. It builds strong bones as the vitamin C improves absorption of the rich calcium content in broccoli.

Recent research shows that broccoli is especially good for the stomach. A compound in it is even better than antibiotics against the bacteria that causes stomach or peptic ulcers.

Green Tea

Tea in general contains naturally occurring compounds called catechins. Green tea is especially high in them. Catechins are flavonoids believed to be powerful antioxidants that neutralize free radicals in the body. Studies indicate that they can slow down the aging process.

People who drink 5 cups of green tea a day have been found to be 16% less prone to heart diseases. Green tea has been linked to cancer prevention as it inhibits the development of new blood vessels that spread the disease. It is also known to repair alcohol-abused livers, and protect against age-related diseases such as Parkinson’s and Alzheimer’s.

Caveat: Do not drink tea on an empty stomach, especially if you have gastric problems, as the acid in the tea can harm the stomach. Nor should you drink green tea or jasmine tea if you have a weak stomach or digestive system.

Fatty Fish

One of the most important foods we can add to our diet in our fight against disease is fish, or more specifically fish oil. Fatty fish such as herring, mackerel, salmon, sardines, and lake trout help protect against cardiovascular diseases, high blood pressure, and stomach ulcers.

They are high in two types of essential omega-3 fatty acids, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), that play a critical role in brain function and heart health. These fatty acids are found in high concentrations in the brain and are especially important for behavioral and cognitive (memory and reasoning) functions.

Some studies have been carried out on children with severe ADHD (Attention Deficit Hyperactivity Disorder) who were given omega-3 fish oil supplements (in some cases together with omega-6 evening primrose oil) over periods ranging from 3 to 7 months. Many of these children showed marked improvement in ADHD symptoms, impulsivity and inattention.

DHA and EPA in fish or fish oil supplements help to lower triglyceride and blood pressure levels, and inhibit the buildup of atherosclerotic plaque that causes hardening of arteries, so helping to diminish the risk of strokes and heart attacks.

Extensive research also show that fish oils reduce inflammation, help prevent cancer, and slow down degenerative diseases such as arthritis and Alzheimer’s Disease.

The American Heart Association recommends eating fish, especially fatty fish, at least twice a week. However children, pregnant women, nursing mothers, and women who might become pregnant are advised to avoid types of fish that carry higher risk of environmental pollutants such as methyl-mercury. They can instead take a quality fish oil supplement that is certified mercury-free by a reputable independent laboratory.

Babies of mothers who are deficient in omega-3 fatty acids during pregnancy, appear to be at higher risk of vision and nerve probems. New research by the Harvard Medical School and National Eye Institute, reported in the journal Nature Medicine, indicates that fish oil supplements containing DHA and EPA may prevent eye disease, specifically retinopathy, that mainly affects diabetics and pre-term infants.
