Micronutrients & recovery
Consuming at least 400 g/d of total fruits and vegetables reduces the risk of cancers of the oral cavity, oesophagus, stomach, and colorectum.
Eat at least 400 grams of fruits and vegetables every day. This is recommended to help reduce the risk of several types of cancer, including those of the mouth, throat, stomach, and colon.
ModerateSupportsMEDIUM confidence
Fruits and vegetables probably reduce the risk for cancers of the oral cavity, oesophagus, stomach and colorectum, and diets should include at least 400 g/d of total fruits and vegetables.
Why this rating
The paper states 'probably reduce' and notes that prospective studies have been inconsistent, relying heavily on case-control studies.
