Most of us assume that we are eating healthy when we choose fresh produce, whole grains and lean meats. But did you know that not all food is created equal? Some types of food contain hidden toxins that can be harmful to our health in the long run.

Here are 5 hidden food toxins that you should avoid:.

1. BPA in Canned Foods

Bisphenol A (BPA) is a chemical that is used in the lining of some cans to preserve foods. Studies have shown that BPA can seep into food and cause hormonal imbalances in our bodies.

Hormonal imbalances can cause a range of health issues, including infertility, obesity and even cancer.

To avoid BPA, choose fresh or frozen foods instead of canned ones. If you must buy canned food, look for brands that clearly state that their cans are BPA-free.

2. Pesticides in Produce

Produce that is not organic may contain pesticides that can be harmful to our health. Pesticides have been linked to a range of health problems, including cancer, developmental disorders and fertility issues.

The best way to avoid pesticides is to choose organic produce. If organic produce is not available or if it is too expensive, you can reduce your pesticide intake by washing your fruits and vegetables thoroughly before eating them.

3. Nitrites and Nitrates in Processed Meats

Nitrites and nitrates are preservatives used in processed meats like bacon, hot dogs and deli meat. These preservatives can break down into nitrosamines in our bodies, which have been linked to cancer.

To avoid these toxins, choose fresh meats instead of processed ones. If you must eat processed meats, look for brands that do not contain nitrites or nitrates.

4. Trans Fats in Packaged Foods

Trans fats are found in many packaged foods like cookies, cakes and chips. These fats increase the risk of heart disease and have been linked to other health problems, like diabetes and obesity.

To avoid trans fats, read the ingredient labels carefully. Avoid any products that contain partially hydrogenated oils or shortening.

5. Mercury in Fish

Mercury is a metal that can be found in some types of fish. High levels of mercury can cause neurological problems, especially in young children and pregnant women.

To avoid mercury, choose fish that are low in mercury like salmon, sardines, and trout. Avoid large predatory fish like shark, tilefish, and swordfish.
