Perhaps you should try some spelling variations:
increase tomato » increase total (Expand search)
decrease pain » decreases pain (Expand search), decrease in (Expand search), decreased brain (Expand search)
pain increase » pain increases (Expand search), pair increases (Expand search), an increase (Expand search)
decrease food » decreases food (Expand search), increase food (Expand search), decreases blood (Expand search)
food decrease » food decreases (Expand search), foods decreases (Expand search), flow decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease pain increase tomato processing ) OR ( decrease AND decrease food decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease pain increase tomato processing ) OR ( decrease AND decrease food decrease ))*.
