A sizable number of people come into my practice and tell me that they feel better on a gluten-free diet, or they think that it is healthy. This is in line with most Americans who, when surveyed, feel that gluten-free is a healthier diet.
We have recent evidence to suggest, at least from a cardiovascular standpoint, that this is not the case. It is no healthier than a standard diet, and it may in fact be somewhat harmful for other reasons, including the removal of a lot of dietary fibers that you would otherwise consume and the reliance on things like rice and seafood-type products. There is evidence to suggest that the latter group of foods potentially has higher levels of heavy metals.
I’ve posted in the past about the gluten-free fad. Now we have a study from the Mayo Clinic.
“There was no significant difference in weight change among participants matched vs mismatched to their diet assignment,” the researchers wrote. There was also no DNA/diet interaction for waist circumference, body mass index, or body fat percentage.
“I had this whole rationale for why these three [DNA variants] would have an effect,” said Stanford’s Christopher Gardner, co-author of the $8 million study. He previously led a smaller study, in 2010, finding that overweight women whose genotype matched their diet lost 13 pounds in a year while those who were mismatched lost just over 4 pounds. “But let’s cut to the chase: We didn’t replicate that study, we didn’t even come close. This didn’t work.”

Beware of companies selling you stuff based on junk science.
It’s important to provide information on the healthfulness of food choices, rather than to simply recommend decreasing portion sizes.
There is a link to the study abstract in the source article here.
Small number of subjects but a crossover design RCT.
Portion sizes and food choices matter.
(so if you go out for Tex Mex eat half the number of tortillas you usually eat and take home half of what’s on your plate for another meal).
Although the title suggests two habits the article lists nine habits.
Plant based people rejoice!
High protein diets may lead to long-term kidney damage among those suffering from chronic kidney disease, according to research led by nephrologist Kamyar Kalantar-Zadeh, MD, MPH, PhD, of the University of California, Irvine.
The research also indicates that a low protein, low salt diet may not only slows the progression of CKD as an effective adjunct therapy, but it can also be used for the management of uremia, or high levels of urea and other uremic toxins in the blood, in late-stage or advanced CKD and help patients defer the need to initiate dialysis.

There is too much emphasis on dietary protein period. Common sense dictates that even in the absence of CKD a low protein, low sodium diet is prudent. Recently I’ve been reducing the sodium and surprisingly food still tastes good. I really notice restaurant meals when too much salt is present. Hell, I’m even eating unsalted cashews.

My Father had diabetes which contributed to his early demise.
My youngest brother was diagnosed with the disease in his 20’s. He is committing slow suicide by diet.
Way back last century when I was in my 20’s I was involved in a local professional group in Dallas TX. The speaker I brought in was one of the country’s leading endocrinologists from UT Southwestern Medical Center. After his talk I thanked him for his time and for enduring a dinner of rubber chicken and mushy vegetables. But what I really wanted was free medical advice.
“Doctor, my father and brother both have diabetes. Do you have any advice for me?”
The good doctor gave me a steely glare over the top rim of his glasses and said,
“Stay as thin as you can as long as you can.”
Conclusion: Coffee drinking was associated with reduced risk for death from various causes. This relationship did not vary by country.
