It wouldn’t be wise if you have diverticulosis or diverticulitis. Diverticulosis usually doesn’t occur in people under the age of 40, but it is becoming more common these days with younger people. My husband found out he had the disease when he was 30 and he has been hospitalized twice in the past 12 years, the first time requiring surgery. His surgeon blamed the Wonder Bread diet of our generation for the rise in the disease in younger people. If you have diverticulitis, nuts are a big no-no!
