Nitrates do not naturally 'grow' in the environment. They are a type of chemical compound that is found in various forms, often as nitrate salts. Nitrates are commonly used in fertilizers and can be found in high concentrations in agricultural areas across America, where they may contaminate groundwater supplies.

Sources of Nitrates

• Agricultural Runoff: Areas with intensive farming, particularly in the Midwest, can have high nitrate levels in the soil and groundwater due to the use of nitrate-based fertilizers.
• Industrial Waste: Nitrates can also be found in industrial waste and may contaminate ground and surface water in areas near industrial facilities.
• Public Water Supplies: In some urban areas, public water supplies may contain elevated levels of nitrates because of contamination from agricultural runoff or industrial waste.

Nitrates are components that are often used in the preservation of food, particularly in meats and processed foods. If you have a sensitivity or allergy to nitrates, consuming foods with high nitrate content can exacerbate your symptoms. Here are the foods that should be limited or avoided if you have a nitrates allergy:

Foods High in Nitrates

• Processed Meats: Products such as ham, bacon, sausages, salami, hot dogs and other deli meats can have high concentrations of nitrates.
• Cured or Smoked Foods: Food items that are cured or smoked, like cured bacon and smoked fish, often contain nitrates for preservation.
• Certain Vegetables: Vegetables such as celery, lettuce, spinach, beetroot, radishes, and carrots naturally have high nitrate levels. However, if your symptoms are primarily due to added nitrates in food processing, you may be able to tolerate these.
• Processed Foods and Fast Foods: Pre-packaged foods, canned goods, and fast foods often contain nitrates. Check labels for ingredients, as they may include "nitrates" or "nitrites."

In addition to these specific foods, it is also advisable to limit your overall intake of processed and fast food and focus on a diet rich in fresh fruits, vegetables, lean proteins, and whole grains.

Important Note

Always consult with your healthcare provider or a dietitian if you suspect an allergy or sensitivity to nitrates. They can provide guidance and personalized advice to help manage your symptoms and avoid potential triggers.
