The good and the bad

For reference, the optimal LDL level for adults is less than 100 mg/dL, and optimal HDL is 60 mg/dL or higher. Higher LDL levels can increase the risk of heart disease, stroke, peripheral artery disease, and other health problems, while higher HDL has a protective effect against cardiovascular disease. Though some of the changes reported in the study were small, the researchers note that they could be meaningful in some cases. For instance, an increase of 5 mg/dL in LDL is enough to raise the risk of a cardiovascular event by 2 percent to 3 percent.

The researchers ran three different models to adjust for a variety of factors, including basics like age, sex, body mass index, as well as medical conditions, such as hypertension and diabetes, and lifestyle factors, such as exercise, dietary habits, and smoking. All the models showed the same associations. They also broke out the data by what kinds of alcohol people reported drinking—wine, beer, sake, other liquors and spirits. The results were the same across the categories.

The study isn’t the first to find good news for drinkers’ cholesterol levels, though it’s one of the larger studies with longer follow-up time. And it’s long been found that alcohol drinking seems to have some benefits for cardiovascular health. A recent review and meta-analysis by the National Academies of Sciences, Engineering, and Medicine found that moderate drinkers had lower relative risks of heart attacks and strokes. The analysis also found that drinkers had a lower risk of all-cause mortality (death by any cause). The study did, however, find increased risks of breast cancer. Another recent review found increased risk of colorectal, female breast, liver, oral cavity, pharynx, larynx, and esophagus cancers.

In all, the new cholesterol findings aren’t an invitation for nondrinkers to start drinking or for heavy drinkers to keep hitting the bottle hard, the researchers caution. There are a lot of other risks to consider. For drinkers who aren’t interested in quitting, the researchers recommend taking it easy. And those who do want to quit should keep a careful eye on their cholesterol levels.

In their words: “Public health recommendations should continue to emphasize moderation in alcohol consumption, but cholesterol levels should be carefully monitored after alcohol cessation to mitigate potential [cardiovascular disease] risks,” the researchers conclude.

Florida man eats diet of butter, cheese, beef; cholesterol oozes from his body

What could go wrong with eating an extremely high-fat diet of beef, cheese, and sticks of butter? Well, for one thing, your cholesterol levels could reach such stratospheric levels that lipids start oozing from your blood vessels, forming yellowish nodules on your skin.

That was the disturbing case of a man in Florida who showed up at a Tampa hospital with a three-week history of painless, yellow eruptions on the palms of his hands, soles of his feet, and elbows. His case was published today in JAMA Cardiology.

Painless yellowish nodules were observed on the patient’s palms (A) and elbows. B, Magnified view of the palmar lesions. These lesions are consistent with xanthelasma, likely resulting from severe hypercholesterolemia associated with a high-fat carnivore diet. Credit: JAMA Cardiologym 2024, Marmagkiolis et al.

The man, said to be in his 40s, told doctors that he had adopted a “carnivore diet” eight months prior. His diet included between 6 lbs and 9 lbs of cheese, sticks of butter, and daily hamburgers that had additional fat incorporated into them. Since taking on this brow-raising food plan, he claimed his weight dropped, his energy levels increased, and his “mental clarity” improved.

Meanwhile, his total cholesterol level exceeded 1,000 mg/dL. For context, an optimal total cholesterol level is under 200 mg/dL, while 240 mg/dL is considered the threshold for ‘high.’ Cardiologists noted that prior to going on his fatty diet, his cholesterol had been between 210 mg/dL to 300 mg/dL.
