Asthma is a chronic respiratory condition that is characterized by the inflammation of the airways. When a person has asthma, his or her airways get inflamed as a result of exposure to any range of asthma triggers. The airways, tubes proximate to your lungs that carry air to and from the lungs, constrict, limiting the amount of air that travels through the airway, swells, and becomes lined with excessive amounts of mucus. Some of the common symptoms that accompany asthma include a feeling of tightness in the chest cavity, wheezing, coughing, and shortness of breath.

When the symptoms of asthma are extreme, the situation is usually referred to as an asthma attack or an episode of asthma. Usually, these symptoms are managed with a combination of drugs (usually bronchodilators which are drugs that help open the airway) and a change in environment.

Asthma is one of the more popular conditions that affect people and has been increasing in prevalence over the years. To date, one in four urban children are affected with asthma, and an approximate 20.5 million Americans have asthma.

The condition was identified by Greeks with the term, aazein, which meant “sharp breath”. While the word aazein first appeared in Homer’s Iliad, it was only used to describe the said medical condition around 450 BC by Hippocrates. Hippocrates noted, during this time, that the spasms relating to asthma were common among tailors and metalworkers. Galen, six centuries later, studied asthma in great detail and observed that the symptoms of asthma included bronchial obstruction. It was later on studied by the influential medieval philosopher, rabbi, and physician Moses Maimonides in 1190 AD, who wrote a treatise on the prevention, diagnosis, and treatment of asthma. The connection between asthma and organic dust was made in the 17th century by Bernardino Ramazzini. It was only in the year 1901 that bronchodilators became widely used, and not until the 1960s that physicians recognized the need for anti-inflammatory medication in order to deal with a previously unrecognized inflammatory aspect of asthma symptoms.

Based on the symptoms displayed by those suffering from asthma, there are four basic levels of asthma severity. The first level is called mild intermittent, which means that the person suffering from asthma has asthma attacks twice a week or less, has regular lung function, is bothered by symptoms at night at least twice a month, and experience no other symptoms. This is a sort of asthma that more or less “comes and goes” and causes no particular discomfort to a person affected by it.

The second level is called a mild persistent asthma. Mild persistent asthma causes asthma attacks more than twice a week but no more than once per day. A person with mild persistent asthma is bothered by asthma at night at least twice per month, and do experience the other symptoms of asthma sufficiently to affect his or her activities.

Moderate persistent asthma means that asthma symptoms manifest themselves everyday, causing discomfort from nighttime symptoms more than once a week. Asthma attacks themselves pose effects to most activities.

Severe persistent asthma, the highest of these four levels, means that asthma symptoms manifest themselves throughout the day on most days, with nighttime symptoms causing inconvenience often. With severe persistent asthma, limits to physical activities exist.

What is Cancer?

All living things are comprised of a variety of cells, such as kidney cells, brain cells and skin cells. Cancer develops when a particular cell mutates, then begins to grow and divide. Eventually, these cells form a mass called a malignant tumor, which often starts to invade surrounding tissue and organs.
Super Foods

It is thought that up to one third of cancer related deaths could be diet related.
Many of the foods we eat today can in fact be harmful to the cells in our bodies, particularly 'fast food', which often contains high rates of saturated fat.
A large European study has recently shown that 'junk food' may in fact be a major cause of cancer of the pancreas, the urinary tract and of the womb, which makes saturated fat especially dangerous for women. There is however, an abundance of super foods that contain cancer fighting anti-oxidants and enzymes. These foods fall into a number of categories and it is best to look at their properties separately.
Fruit and Vegetables

    * Raw carrots are rich in beta carotene and substances called falcarinol and polyacethylens, which can help to impede a wide variety of cancer including, breast, stomach, throat, lung, prostate, bladder and intestinal
    * Sweet potatoes are thought to have a number of cancer fighting properties including carotenoids (beta carotene is one form)
    * Turnips and their leaves contain a substance called glucose molaes, which is said to attack cancer cells
    * Broccoli, cauliflower, cabbage, kale and sprouts are rich in the anti-oxidants; lutein and zeaxanthin which are thought to be particularly affective at inhibiting breast and prostate cancer
    * Broccoli and sprouts also contain a substance called phytochemical sulforaphane, which is a by-product of glucoraphanin and is especially useful at impeding bowel cancer
    * Kale is thought to retain indoles, which are nitrogen compounds and are said to prevent lesions in estrogen sensitive areas, such as the ovaries, mutating into cancerous cells
    * Beetroot is full of anti-oxidants that specifically attack lung cancer cells
    * Tomatoes carry vitamin C and a carotenoid called lycopene that fights oxygen molecules which are also known as 'free radicals'. Free radicals are often believed to trigger cancer cells. Lycopene is notable in its ability to aid the fight against rectal and colon cancer, as well as prostate, breast, mouth and cancer of the pancreas. Cooked and canned/pureed tomatoes are said to be especially concentrated in lycopene
    * Soya bean products such as tofu include phytoestrogens and isoflavones, which when absorbed in sensible amounts (no more than four or five ounces per day) are thought to block and help prevent cancer cells from forming and are particularly associated with lowering the risk of breast cancer. Incidences of breast cancer are significantly lower in Asian countries where soy products are consumed regularly. However, caution must be exercised, as research suggests that eating too much soy may cause hormone imbalances which can in fact stimulate cancer cells
    * Avocados have prolific amounts of an anti-oxidant called glutathione. Glutathione attacks free radicals and stops the absorption of certain saturated fats into the intestine. Avocados contain high levels of beta-carotene and potassium, which is also very beneficial for the heart
    * Citrus fruits, such as oranges, grapefruits, lemons and limes possess high amounts of vitamin C, folic acid and monoterpenes, which can help to eliminate carcinogens from the body and are believed to repress cancer cells
    * Papayas carry prolific amounts of vitamin C and folic acid, which are both highly effective anti-cancer components
    * Figs contain a form of benzaldehyde, which is renowned for its ability to shrink tumors
    * Grapes, particularly the red varieties, include resveratrol and ellagic acid which combine to block the enzymes that are responsible for the growth of cancer cells. They also contain strong anti-oxidants called bioflavonoids
    * Strawberries, raspberries, blackberries, blueberries and other berries that are red or black in color consist of a wide variety of antioxidants, vitamins and minerals, and plant compounds that are thought to be very beneficial against many forms of cancer

Herbs and Spices

    * Rosemary is said to have detoxifying properties and can repress the advancement of tumors. Laboratory tests have revealed that it is principally effective against breast and skin tumors
    * Tumeric belongs to the ginger family and it is thought to help reduce the inflammation that is connected to stomach, bowel and colon cancer
    * Root ginger has been used by Chinese medics for centuries and is well regarded for its many healing benefits. It can be used as a spice in savoury and sweet dishes and as a herbal tea
    * Garlic is well renowned for its blood thinning and anti-bacterial properties. It can also help to eliminate oxidants that cause cancer, such as carcinogens and free radicals. Eating raw or cooked garlic has been found to be far more effective than taking garlic supplements
    * Licorice root contains a chemical called glycyrrhizin which is considered to help block the growth of prostate cancer cells, though an excessive consumption of licorice can lead to raised blood pressure
    * Chilli peppers are rich in a substance called capsaicin that is regarded to be a preventative against intestinal cancer

Beverages

    * Black, green and white teas retain antioxidants which are also known as polyphenols. These antioxidants are considered to expressly defend against cancer cells and stop them from dividing and spreading. White and green tea is regarded as being particularly efficient against lung, colon, rectal and stomach cancer as well as cancer of the liver and pancreas
    * Red wine also contains polyphenols and a substance called resveratrol which has been discovered to be present in grape skin. These antioxidants are known to counter free radicals. It is thought that the pinot noir grape variety contains the largest amounts of resveratrol, particularly in wines where the grapes are grown in cooler, rainy climates, such as Chile in South America. However, alcohol is consumed in large amounts it can actually be a cause of cancer, so it is best drink no more than one glass of red wine per day.

There are many other foods that are considered to be wonderful cancer preventatives. Seaweed and sea vegetables contain fiber, proteins, beta-carotene, folic acid, and a fatty acid called chlorophylone.

These forms of vegetable are said to help prevent breast cancer. Nuts and seeds are naturally high in omega-3 fatty acid, which is essential for brain function. Nuts also contain a mineral called selenium and are rich in antioxidants such as quercetin and campferol. Nuts and seeds are regarded as primarily effective at repelling prostate and colon cancer cells, as well as being a natural preventative against the threat of heart disease. Mushrooms have prolific amounts of potent compounds called polysaccharides. These compounds are thought to build up immunity against cancer cells. Certain varieties of mushroom are perceived to be particularly efficient, these include; reishi, shiitake and maitake, and are widely used in Japanese cuisine.
The benefits of eating a healthy, balanced diet have become more apparent as research into cancer and other fatal diseases evolve.

A diet rich in vegetables, fruit and lean meat is much more of a priority in our daily lives than it was twenty years ago and medical advice suggests that eating at least five portions of fruit or vegetables per day can significantly lower the risk of many forms of cancer and heart disease, as well as preventing obesity. The threat of obesity is a volatile issue and for the first time in many years the life expectancy of our children is thought to be lower than our own, which is an extremely worrying statistic.We are bombarded with these frightening medical statistics on a regular basis. Yet the most sensible advice we have been given in recent years is to eat at least five portions of fruit or vegetables per day. Taking action now may well lessen our chances of developing cancer and should help to provide numerous other health benefits for many years to come.
