Not sure what you're asking.But, I think some environmental influences are geographic location, resources, culture, weather and climate
Explanation:
location- Water access might allow for more fishing. So livinf close to the ocean you might eat shrimp,fish, and other seafood mpre often than those inland.
resources- you might have a limited food supply near you. Maybe you can grow peanuts because you don't have sand or you cant grow sweet corn because you don't have moist soil.
Weather and climate- Can't eat tropical foods where it's cold. Foods that require lots of water such as rice Can't grow where it's dry.
