- "Studies indicate that the omega-3 fatty acids found in walnuts may help lower cholesterol; protect against heart disease, stroke and some cancers; ease arthritis and other inflammatory diseases; and even fight depression and other mental illnesses."
- "[O]mega-3 fatty acids inhibit the tumor growth that is promoted by the acids found in other fats... "
- "[I]n treating major depression, for example, omega-3s seem to work by making it easier for brain cell receptors to process mood-related signals from neighboring neurons."
- "The omega-3s found in fish oil are thought to be responsible for the significantly lower incidence of breast cancer in Japanese women as compared to women in the United States.
In one study, mice that ate the human equivalent of 2.4 ounces of whole walnuts for 18 weeks had significantly smaller and slower-growing prostate tumors compared to the control group that consumed the same amount of fat but from other sources. Overall the whole walnut diet reduced prostate cancer growth by 30 to 40 percent. According to another study on mice, the human equivalent of just two handfuls of walnuts a day cut breast cancer risk in half, and slowed tumor growth by 50 percent as well. Other research has shown walnuts may:
- Significantly reduce LDL cholesterol levels
- Reverse brain aging in rats
- Boost heart health in diabetics
