Looks European-American to me
European-American? I guess that’s American women who are of European descent rather than Asian, Eskimo, African, etc.
LCHF in my headline refers to low-carb, high-fat.
GERD is gastro-esophageal reflux disease, i.e., frequent or severe heartburn. GERD is the most common reason to use a proton pump inhibitor drug like Prilosec. It’s expensive. I run across patients taking it every day for years.
Dr. Michael Eades has a great post about GERD and the potential drawbacks of proton pump inhibitors (PPIs):
The scientific literature has shown long-term PPI therapy to be related to the following conditions:
Anemia
Pneumonia
Vitamin B12 deficiency
Impaired calcium absorption
Impaired magnesium absorption
Increased rate fractures, especially hip, wrist and spine
Osteopenia [thin brittle bones]
Rebound effect of extra-heavy gastric acid secretion
Heart attacks
From the recent study at hand:
“GERD symptoms and medication usage was more prevalent in European-American women, for whom the relationships between dietary carbohydrate intake, insulin resistance and GERD were most significant. Nevertheless, high-fat/low-carbohydrate diet benefited all women with regard to reducing GERD symptoms and frequency of medication use.”
Pay attention and follow all the links and you may be able to see the entire journal report. You just can’t wait, right?!!
Another study showed improvement in heartburn with a low-carb diet a few years ago.
All of my diet books offer low-carb high-fat options except for the original first edition of Advanced Mediterranean Diet from 2007. In 2009, I learned that low-carb high-fat eating wasn’t dangerous. Hence, the 2nd edition.

Not a woman, but of European descent. It took years for me to figure this out, but if I eat wheat then I get heartburn. If I don’t eat wheat then I don’t get heartburn, whether or not I go low carb.
