While not specifically CLL related, I found Dr Koffman's recent blog covering the paper "Association of Nut Consumption with Total and Cause-Specific Mortality" published in the New England Journal of Medicine well worth reading:
Association of Nut Consumption with Total and Cause-Specific Mortality
"In two large, independent cohorts of nurses and other health professionals, the frequency of nut consumption was inversely associated with total and cause-specific mortality, independently of other predictors of death."
There was a 17% reduction in the risk of dying in the study period for those that included nuts in their diet. "The reductions for heart disease was even bigger, 29% and for kidney disease it was a whopping 39%. Cancer deaths were cut by respectable 11%"
As Dr Koffman correctly points out, correlation doesn't mean causation; your health may not be improved because you eat nuts, but because you have chosen to live a healthier lifestyle: "Do nuts eaters tend to avoid more junk food, do they make better health and food choices overall and that is the reason for their improved survival?"
Also, note that this study was "funded by the National Institutes of Health and the International Tree Nut Council Nutrition Research and Education Foundation."
Dr Koffman also covers some not so well known dangers associated with eating nuts. While I was well aware of the risk of aflotoxin poisoning from eating peanuts, I wasn't aware that a handful of brazil nuts may contain as much as 10 times the daily recommended dose of selenium!
I started adding a wider variety of nuts to my diet after a nutritionist suggested almonds could help reduce CLL related fatigue. I don't know if that has helped, but a variety of nuts are certainly now a enjoyable part of my diet.
I don't think that even Dr Koffman would enjoy eating gum nuts, but I see he does enjoy Australian native Macadamia nuts which have to be one of the best if not the best nut variety available.
And what Aussie doesn't remember with fondness May Gibbs' gumnut babies Snugglepot and Cuddlepie and the big bad banksia men from their childhood days:
