Chemicals such as pesticides, antibiotics, and hormones are widely used in plant and animal farming to increase production. There are various reasons for this, from increased yields to reduced food waste and improved appearance and taste. There are a lot of pesticides and other chemicals in our food. Read on to learn more.
Fruits and Vegetables
Fruits and vegetables can be contaminated in a variety of ways before they reach us. Pesticides, which are potentially toxic to humans, as well as fertilisers and other chemicals, help control pests, weeds, and diseases, but they also pose a serious threat to our health. The type of contamination of fruits and vegetables depends on the type of produce, how it was grown, how it was transported, and how it was stored and handled.
Food can also become contaminated after we buy it, during food preparation, or through improper storage. Regardless of the type of contamination, it must be physically removed before consumption to avoid foodborne diseases. According to health officials, millions of people worldwide fall ill each year from food contaminated with harmful bacteria.
Research shows that a significant number of people do not wash fruits and vegetables after taking them out of packaging or the refrigerator. The number one rule when it comes to consuming fresh produce is to wash them under running water, even if they are packaged, like tomatoes or capsicums, or pre-washed like spinach and salads.
Commercial prewashing involves the use of chemicals that need to be physically removed by running water. The same rule applies to organic products.
What are the Potential Health Risks
Pesticides, fertilisers, and other chemicals used in food production to increase the yields and improve the appearance and taste of products pose potential health risks when ingested. They can cause the development of acute and chronic health problems, such as:
- Increased risk of cancer
- Reproductive and developmental problems
- Neurological problems
- Liver disease
- Kidney disease
- Heavy metal accumulation in the body
- Endocrine disruption
- Genetic mutations
How to Reduce Exposure to Chemicals
Some ways to reduce exposure to chemicals include:
- Choose organic produce – Organic farming prohibits the use of synthetic pesticides and fertilisers.
- Eat a variety of foods: – Eating a variety of foods can help reduce your exposure to any one type of pesticide.
- Wash and peel produce – Washing and peeling produce can help remove some pesticide residue.
- Buy local produce – By buying produce from local farmers and supporting sustainable farming practices, you can help reduce the use of chemicals in food production.
- Cook food thoroughly – Cooking food thoroughly can help remove any remaining pesticide residue.
- Be aware of the “Dirty Dozen and “Clean Fifteen” lists – The Environmental Working Group (EWG) publishes annual lists of fruits and vegetables with the highest and lowest levels of pesticide residues.
