You may want to think twice before ordering a hot dog, hamburger, or even a glass of beer. These products all contain nitrites and nitrates, which are harmful to people and animals.

A group of researchers at Rhode Island Hospital observed parallels in mortality rates from diseases associated with aging, such as Alzheimer's, diabetes, and Parkinson's, with increased exposure to nitrates and nitrites through processed foods, fertilizers, cosmetics and pesticides. 

Nitrosamines, formed by a chemical reaction between nitrites or other proteins, are commonly found in foods like ground beef, bacon, and cured meats, and ultimately cause DNA damage. Researchers suggest the cellular changes that occur due to nitrosamine exposure are comparable to those that occur with aging and age-related diseases.  

If you want to reduce your exposure to nitrosamines:

• Avoid frying or flame broiling food as sodium nitrate forms at high temperatures
• Buy organic produce when possible
• Reduce intake of processed and fast food
