The invisible threat to healthy eating: Pesticides

Nutrition and Diet Specialist Hülya Yiğit pointed out that exposure to pesticides can be linked to hormonal imbalances, immune system problems, and certain types of cancer. Yiğit stated that research has revealed that pesticide exposure, especially in children and adolescents, can increase the risk of attention deficit and behavioral disorders. Emphasizing that truly healthy eating is closely related not only to what we put on our plates but also to how that food is produced and processed, Yiğit expressed that such health risks can only be minimized through conscious and careful consumption.

THIS DANGER SHOULD NOT BE IGNORED WHEN CONSUMING VEGETABLES AND FRUITS!

Experts, stating that the first thing that comes to mind when talking about healthy eating is consuming plenty of vegetables and fruits, warn: 'However, this recommendation also brings up an important issue that should not be ignored: Pesticides...'

Emphasizing that these chemical substances used in agriculture are intended to protect products from pests, but that their effects on human health are significant, Yiğit said: 'In early 2025, some agricultural products sent from Turkey to European Union countries, especially dried figs and grape leaves, were turned back from customs due to pesticide and aflatoxin residues. These developments show that the issue of pesticides is an important matter that concerns not only exports but also the products that come to our tables.'

Pesticide exposure can increase the risk of attention deficit and behavioral disorders in children and adolescents

According to the World Health Organization, pesticide exposure is associated with hormonal disorders, immune system problems, and certain types of cancer. Experts point out that individuals in the adolescent period are more sensitive to such chemicals because they are in a developmental process. Research shows that exposure to pesticides in children and adolescents can increase the risk of attention deficit and behavioral disorders.

Stating that it is natural to ask 'should we not eat vegetables and fruits?' in this situation, Yiğit continued her words as follows:

'On the contrary, these foods are indispensable for a healthy life. However, it is possible to reduce these risks with careful and conscious consumption. First, soak vegetables and fruits in carbonated water, then rinse and wash them separately with vinegar water. Do not combine this process, because some pesticides can dissolve in an acidic environment and pass into the food. If possible, prefer organic products or seasonal and local products. Do not put products bought from the market or grocery store into the refrigerator without washing them. Residues on the surface can also pass to other foods through contact. When shopping, prefer reliable sources with food safety certificates. Certified producers and inspected markets should be prioritized.'

HEALTHY EATING IS ALSO DIRECTLY RELATED TO HOW THE FOOD PUT ON THE PLATE IS PRODUCED

Pointing out that which products have the most pesticide residues is shared with the public by independent organizations every year, the expert said, 'The Environmental Working Group (EWG), an independent environmental health organization based in the USA, ranks the products with the most and least pesticides every year.'

Referring to these data, Yiğit concluded her words as follows:

'According to the 2024 data of the EWG, products with the most pesticide residues included strawberries, spinach, kale, grapes, peaches, pears, apples, cherries, peppers (sweet and hot), blueberries, nectarines, and green beans. The products considered the cleanest were avocados, sweet corn, pineapples, onions, papayas, frozen peas, asparagus, melons, kiwis, cabbage, watermelons, mushrooms, mangoes, sweet potatoes, and carrots. Although this list is US-based, it is an important reference for agricultural production and pesticide residues worldwide. Especially for sensitive groups such as children and adolescents, such information contributes to making more conscious choices. Let us not forget; truly healthy eating is directly related not only to what we put on our plates but also to how that food is produced and how it is processed.'
