Chronic Obstructive Pulmonary Disease or in the further text COPD is a name for all lung diseases in a progressive state like asthma, bronchiectasis, emphysema and chronic bronchitis.

This is one of the leading causes of death in USA. The common symptoms of COPD are frequent coughing, wheezing, tightness in the chest and breathlessness.

Millions of people around the world are affected by this disease, so what are the factors that cause COPD?

1. In first place, smoking, even if you are former smoker you can develop COPD. This usually occurs in people over 40 and 90 percent of them have COPD if they have history of smoking.

2. Genetic factors are one of the reasons for developing COPD. A deficiency of protein called Alpha-1 Antitrypsin is the main cause for emphysema. So the lack of this protein in the bloodstream causes lung deterioration because the white blood cells damage the lungs.

3. And there are environmental factors of course like secondhand smoke, fumes, dust and other lung irritants. In this category are people who had long term contact with chemicals or harmful pollutants at work. They can also develop COPD.

Nowadays you can find many different treatments and drugs to help with COPD but many researches have proved that there is a natural treatment to cope with the COPD.

There was a study conducted on rats with emphysema by Dr. Donald Massaro and Dr. Gloria De Carlo Massaro from the University School of Medicine in Georgetown.

They managed to completely reverse emphysema at rats by using ATRA- derivate of vitamin A. After only 12 days rats were able to produce alveoli, so the carbon dioxide and oxygen started to move between the bloodstream and lungs.

Cigarettes together with the carcinogen compound called benzopyrene waste all vitamin A from the organism. But luckily there are two super ingredients that can dramatically help in treatment with COPD. They are Vitamin A and Beta- Carotene.

The compound that gives the color to the vegetables and fruits is called Beta- Carotene. When we eat those foods the Beta-Carotene inside the body turns into vitamin A which is beneficial to our health.

So if you want to improve the concentration of vitamin A and Beta- Carotene in your body than you should start consuming these top ten foods rich in Beta- Carotene: Carrots, sweet potatoes, lettuce, dark green leafy vegetables, cantaloupe, dried apricots, broccoli, peas, squash and sweet red peppers.

The best way that these foods can be absorbed is to eat them with healthy fats, thus you will increase their bio availability.

You can cook them in oil, chop in a salad or just make a fresh juice, any way is the best way to increase their intake and fight the COPD.
