BHA and BHT in Food: Explained.
When you grab a bag of chips or a box of crackers from the grocery store, you might notice some unfamiliar ingredients listed on the back. Two of these ingredients are BHA and BHT. But what are these preservatives, and what do they do? Here's what you need to know about BHA and BHT in your food.
1. What are BHA and BHT?
BHA and BHT are chemicals commonly used as preservatives in food. BHA stands for butylated hydroxyanisole, and BHT stands for butylated hydroxytoluene. Both are antioxidants, meaning they help prevent the oxidative decay of food products.
2. Why are they used in food?
BHA and BHT are used in food to extend its shelf life and prevent spoilage. They can help protect against rancidity, discoloration, and the formation of harmful compounds in food. These preservatives are commonly added to foods that are high in fat or oils, including baked goods, snack foods, and processed meats.
3. Are they safe to consume?
BHA and BHT have been approved for use by the United States Food and Drug Administration (FDA) as safe preservatives in food. The World Health Organization (WHO) and the European Union (EU) have also deemed these chemicals safe for use in food. However, some studies have suggested that long-term exposure to high levels of these preservatives may have negative health effects.
4. What are the potential health risks?
While BHA and BHT have been deemed safe for consumption in small amounts, some studies have linked high levels of these preservatives to negative health effects. Animal studies have shown that excessive exposure to BHA and BHT can cause damage to the liver, kidney, and thyroid. Additionally, some studies have suggested that long-term exposure to these preservatives may increase the risk of cancer.
5. How can you reduce your exposure to BHA and BHT in food?
If you're concerned about your exposure to BHA and BHT in food, there are several steps you can take to reduce your intake. Choose fresh, whole foods instead of processed foods that are likely to contain these preservatives. If you do choose to consume processed foods, read the ingredient labels carefully and choose products that do not contain BHA or BHT. Additionally, consider cooking your own meals at home using fresh ingredients to have better control over the additives in your food.
In conclusion, BHA and BHT are common preservatives used in many processed foods. While they have been deemed safe for consumption in small amounts, some studies have suggested that long-term exposure to high levels of these preservatives may have negative health effects. By choosing fresh, whole foods and reading ingredient labels carefully, you can help reduce your exposure to these preservatives in your diet.
