Having seen the occasion recommendations to avoid dairy food in responses about diet, these two items in today's news attracted my attention.
"Enjoying full-fat milk, yogurt, cheese and butter is unlikely to send people to an early grave, according to new research by The University of Texas Health Science Center at Houston (UTHealth)
The study, published today in the American Journal of Clinical Nutrition, found no significant link between dairy fats and cause of death or, more specifically, heart disease and stroke -- two of the country's biggest killers often associated with a diet high in saturated fat. In fact, certain types of dairy fat may help guard against having a severe stroke, the researchers reported."
While not specific to CLL, the study does cover demographics that strongly overlap that of people with CLL: "Nearly 3,000 adults age 65 years and older were included in the study, which measured plasma levels of three different fatty acids found in dairy products at the beginning in 1992 and again at six and 13 years later.
None of the fatty acid types were significantly associated with total mortality. In fact one type was linked to lower cardiovascular disease deaths. People with higher fatty acid levels, suggesting higher consumption of whole-fat dairy products, had a 42 percent lower risk of dying from stroke." (My emphasis)
And from today's The Conversation: We ask five experts, Is cheese bad for you?
As is highlighted in the comments to the above article, there may well be ethical reasons for avoiding dairy products, but it appears from recent research that health factors shouldn't be a concern.
