Update on red and processed meat and colon cancers
The health and nutrition community has been sounding the alarm on red and processed meats and its well-established link to colorectal cancers for at least the last decade.
Age faster with processed meats
I've written in numerous Health & Nutrition Bites about telomeres, the DNA sequences that are considered markers of cellular aging (read a broader explanation of their function).
Is meat bad for you?
Red meat is not bad for you. Bologna is bad for you. Not a little bad, but a lot bad, and this holds true for most processed meats. Eating hamburger is OK, pork chops not bad, chicken is fine, but not most deli meats.

It appears that following a more Mediterranean-style diet may help prevent the development of diabetes in overweight women even more than in women of clinically normal weight.
In an article recently published in JAMA Network Open (2020;3(11):e2025466), an international team of researchers analyzed data gathered for the Women's Health Study, an ongoing prospective study of over 25,000 women that began recruitment in in 1992 and has continued gathering data through December 2017.
Each participant responded to demographic questionnaires as well as health questionnaires that were updated via written survey every year. At the start of the study the participants provided blood samples for metabolic testing and completed a detailed dietary questionnaire that allowed the researchers to assign each participant a Mediterranean Diet score ranging from 0 to 9.
After almost 25 years of data gathering, the authors compared the Mediterranean Diet scores of those who developed diabetes with those who did not.
For their analysis, in addition to breaking down the Mediterranean Diet score into low, medium, and high (0-3 points, 4-5 points, and 6-9 points), the authors took into account the participants' Body Mass Index as well as their metabolic scores, including blood pressures and cholesterol scores.
It should be no surprise that overall, those whose Mediterranean Diet scores were 6 or above were far less likely to develop diabetes than those whose Mediterranean Diet scores were 3 or below - as much as 30% less likely.
What's a surprise in this study is that when the authors separated the participants by Body Mass Index, grouping them into BMI 25 or over (clinically overweight) or BMI under 25 (clinically normal weight or underweight), they found that the reduction in risk of diabetes applied only to those women whose BMI was 25 or higher (clinically overweight).
While excess body weight can mean an increased risk of several chronic diseases, from diabetes to some cancers, this research helps underscore that improving what you eat can have just as much - if not more - of an effect on your health as weight loss.
