BENGALURU: From watermelon, green and black grapes to bright red apples, the allure of fresh fruits is no longer confined to their natural growing seasons. However, as these vibrant produce become available year-round, experts warn that non-seasonal fruits often contain higher levels of pesticides and preservatives, and consuming them can be risky.
While it is typically believed that some fruits are easy to grow in the state because of easy adaptation to diverse soil types, agri-experts highlight that fruits like strawberries, grapes, and apples cannot be grown without the use of preservatives, and advanced storage techniques.
A horticulture expert explained that while many believe that exotic fruits, especially dragon fruit is grown with minimal use of preservatives, as its thick skin helps protect the fruit during transport and storage, in reality, the local climate is not supportive for production and storage of these fruits, and can be maintained only with preservatives.
Experts highlight hidden health risks, in off-season fruits, as they lack nutritional value compared to their seasonal counterparts.
Consultant Dietician at Motherhood Hospitals Dr Reenu Dubey explained that off-season fruits are often subjected to heavy preservation methods including use of pesticides, fungicides, and artificial ripening agents, which can lead to allergies, infections, and gastrointestinal problems.
“Chemicals used in preservation process can cause short-term side effects such as headaches, dizziness, and nausea. Long-term consumption may result in chemical accumulation in the body, contributing to chronic diseases like cancer and endocrine disorders,” she added.
Additionally, non-seasonal fruits are typically harvested before they are fully ripe, resulting in lower nutritional value and potential deficiencies in essential vitamins and minerals, which can adversely affect health and immunity, she added.
Dr Reenu stressed that artificial ripening agents such as calcium carbide present serious health hazards including neurological disorders and respiratory problems. To maintain freshness and appearance during transport, these fruits are coated with wax, and preservatives which can lead to digestive issues and lead to accumulation of toxic substance if consumed for a long period of time.
Fortis Hospital Dietician Bharathi Kumar explained that while the residues are usually minimal and regulated, they are a cause of concern. She also highlighted that the environmental impact of these practices is significant, as off-season fruits are transported to far off places, leading to a more carbon footprint.
