Extreme weather may cause produce to be less nutritious

Levels of protein as well as iron, copper and zinc in food may have been affected by extreme weather. According to Professor Mike Gooding, head of agricultural policy and development at Reading University in the U.K., says high rainfall could cause loss of nutrients in soil while lack of sunshine could hamper the development of sugars in produce, causing the nutrients available to the plant to be reduced. 

Rainfall, for example, will often cause leaching and loss of nutrients from the soil, and at certain times that will certainly reduce the amount of protein that ends up in the produce.

However, in some instances where the poor weather has resulted in a dramatically-reduced number of crops being produced, a reverse effect might take place for those that have survived. If yield goes down more than the nutrition and the nutrients, the concentration will actually go up.
