Question

which effect is associated with overnutrition?

increased risk of vitamin poisoning
increased cognitive function
decreased risk of mineral poisoning
decreased risk of obesity

Explanation:

Overnutrition refers to excessive intake of nutrients. Vitamin poisoning occurs when there is an excessive intake of vitamins (which are a type of nutrient). Increased cognitive function is not related to overnutrition (it could be due to other factors like proper brain - stimulating activities etc.). Decreased risk of mineral poisoning is incorrect as overnutrition of minerals (if any) would increase the risk. Decreased risk of obesity is wrong because overnutrition (especially of calories) is associated with increased risk of obesity.

Answer:

Increased risk of vitamin poisoning
