<s>[INST] Exposure to allergens can be a vicious circle. While allergens have been linked to asthma, they are also linked to the obesity epidemic that has swept the United States. While genetics obviously play a significant role in obesity, environmental factors such as the food we eat and the air we breathe also play a role, particularly in children. Research has linked exposure to pollutants in the air to increased body fat. It's a double whammy because the more body fat a person has, the more they are likely to produce inflammatory chemicals that will aggravate respiratory problems like asthma. As we know, the food we eat can have a significant impact on our body's production of inflammatory chemicals. Regarding Chronic Obstructive Pulmonary Disease (COPD), research has shown that a diet low in fruit and vegetables but high in red meat may be linked to a higher risk of developing respiratory problems.

So this is a big deal for Americans; especially for their children... America is a nation once built on farm-to-table freshness, wholesome food and pure air. When did the change occur?[/INST]
