Sodium intake linked to risk for atopic dermatitis (Each gram of sodium over 3.30 grams meant a 22% higher chance of current dermatitis)

Increased consumption of dietary sodium may increase the risk for atopic dermatitis, according to a study presented at the annual meeting of the Society for Investigative Dermatology, held May 18 to 21 in Portland, Oregon.

Morgan Ye, M.P.H., from the University of California San Francisco, and colleagues examined the association between sodium intake and atopic dermatitis in a U.S. population-based cohort of 13,183 children and adults identified from the 1999-2000, 2001-2002, and 2003-2004 cycles of the National Health and Nutrition Examination Survey.

The researchers found that the average dietary sodium intake was 3.30 g and 6 percent of participants reported current dermatitis at the time of the survey, while 12 percent of participants reported dermatitis in the previous year. A 1-g increase in dietary sodium intake was associated with an increased risk for current dermatitis (adjusted odds ratio, 1.22; 95 percent confidence interval, 1.02 to 1.45) and a nonsignificant increase in the risk for dermatitis in the previous year (adjusted odds ratio, 1.15; 95 percent confidence interval, 0.98 to 1.34), when adjusting for potential confounders, including age, sex, ethnicity, and poverty income ratio.

"These data support salt restriction as a low-cost, safe intervention for atopic dermatitis that could be offered in diverse settings, although additional research is needed using more specific measures of atopic dermatitis in a longitudinal population cohort," the authors write.

Working with odds ratios requires some word changes, hence the title describing it from the perspective of people who already have dermatitis, rather than the general population’s likelihood.

I always wonder about sodium warnings. From what I’ve seen of Asian cooking, that region has salt built heavily into a great many dishes. Do the stated health concerns show up proportionately in Asia? Or is this just a study of some Irish and German guys living in the USA?

[Robert DeLong]

I use a lot of salt, and never had those problems.

This one is kind of hard to swallow. Back in the day, lots more salt was used for preserving everything.

I had it explained to me by a man that has long-standing in the bio research profession that the original salt-hypertension connection was made because the study focused exclusively on a minority pop from sub-Saharan Africa, imported due to resistance to malaria for work in the rice-producing areas of the southern US.

Being from a tropical clime, there was an adaptation that caused the body to hold onto salts and minerals that would otherwise be excreted through sweat. So a little bit added could become toxic.

No other pop has that issue.

Most of what came out of the “health sciences” of the 1920 and ‘30s is garbage.

Much of what has come since has been consuming grants and turning out garbage to justify spending the grant money.

[ClearCase_guy]

Thanks. That definitely fits with what I suspected.

Given all that we have learned about such research by politically motivated Leftists that infect these institutions, I must admit I don’t believe a damned thing that they publish in their “studies”.

[ConservativeMind]

Indeed. This was only talking to current sufferers, not necessarily the propensity of anyone else to get it, but it doesn't eliminate it from being possible for non-sufferers.

I was employed for a couple years by International Salt to mine salt 1,500 ft. beneath Lake Erie.

Just bragging.

“Back in the day, lots more salt was used for preserving everything.”

That’s right. And back in the day people did not live as long as they do now either.

If one has heart or kidney issues one should consult with their doctor about levels of salt intake. I have made some progress in that regard although I do enjoy salty food.

I’ve had atopic dermatitis for many years. For me WHEAT triggers the eruptions, not salt. Have to shoot Dupixent as needed (every 5-10 weeks) to calm it down.
