@dailymail: A new study by UK-based researchers at Deep Science Ventures suggests that fruits, vegetables and cereals contain 20-50% less of several key nutrients than they did in the 1960s. The decline is partly attributed to deteriorating soil quality and crop-breeding practices focused on increasing yields. Researchers warn that people may need to eat twice as much of certain produce to obtain the same levels of essential minerals, raising concerns about micronutrient deficiencies. Several decades of crop breeding and farming practices aimed at boosting yields may have contributed to declining nutrient levels in many crops. #Science #fruits #vegetables #food
