(21-07-06) How to Virtually Eliminate Your Risk of Lymphoma

Eating lots of vegetables lowers the risk of non-Hodgkin lymphoma (NHL), according to a Mayo Clinic study. After examining the dietary intake of 466 people with NHL and 391 matched controls, researchers found that:
? Those who ate a higher number of vegetable servings per week had a 42 percent lower risk of NHL than those who ate the lowest number.
? Those who ate the most servings of green leafy vegetables and cruciferous vegetables had a 40 percent lower risk compared to the lowest intakes.
? Those who had the highest intake of the carotenoids lutein and zeaxanthin had a 46 percent lower risk of NHL.
? Those who had the highest intake of zinc had a 42 percent lower risk.
The researchers believe the reduced risks are due to the antioxidant effects of the carotenoids in vegetables. An antioxidant-rich diet helps fight DNA damage caused by oxidative stress, which is one of the risk factors for non-Hodgkin lymphoma.
