Experts have uncovered a few links between your diet choices and skin health.
There are many lifestyle changes you can make to help manage eczema —from picking the right moisturizer to tweaking your shower routine—so diet is an obvious factor to consider. But don’t clean out your pantry just yet. Experts have not yet found clear evidence that your diet choices can cause or exacerbate eczema symptoms, like dry, itchy skin.
One notable exception has to do with food allergies. Some 37 percent of children with moderate to severe eczema have some type of food allergy, according to the American College of Allergy, Asthma, and Immunology, compared to just 8 percent of general population of children.
The most common food allergies among people with eczema are dairy, nuts, and shellfish, according to dermatologist Suzanne Friedler, MD, of the Mount Sinai Hospital and St. John’s Episcopal Hospital. Just don’t confuse eczema symptoms, like rashes and flaky skin, with allergy symptoms, like hives. For eczema patients with food allergies, eliminating those foods from your diet should also help minimize eczema symptoms and flare-ups. But there’s no proof that eliminating these foods from your diet if you don’t have allergies will make a big difference.
Some people with eczema attempt elimination diets, in which you completely cut out certain kinds of food for weeks at a time to see if there’s a change in eczema symptoms. Dr. Friedler doesn’t recommend these as a matter of course, but if you do suspect that certain kinds of foods are aggravating your skin, keep a food diary to spot potential eczema triggers, she suggests.
Though relatively rare, another allergy that can trigger eczema symptoms is nickel. You’ve probably heard of children being allergic to jewelry made of nickel, but this metal actually shows up in the diet, too. Nickel can leach into foods through the soil, cans, manufacturing equipment, faucets, and cookware. If you have a nickel allergy, a nickel-free diet, which involves lifestyle tweaks like avoiding canned goods or not cooking in stainless steel cookware, may help treat your eczema symptoms.
You may have heard about making specific dietary changes like eating more anti-inflammatory foods, like omega-3 fatty acids, to reduce eczema symptoms. (Here are some top sources of omega-3 fatty acids to try.) While there isn’t solid evidence to show this treats eczema specifically, it’s eating more anti-inflammatory, whole foods is solid general health advice, so it doesn’t hurt to try.
00:00.000 --> 00:04.504
00:04.504 --> 00:08.610
For most people, diet doesn't play
a big role in managing eczema symptoms.
00:08.610 --> 00:12.740
There's not a lot of research that shows
that certain food, causes eczema to flare,
00:12.740 --> 00:15.000
unless you already have a food allergy.
00:15.000 --> 00:19.090
For example, children with atopic
dermatitis, which is the most common kind
00:19.090 --> 00:22.490
of eczema, often have allergies to dairy,
nuts, and shellfish.
00:22.490 --> 00:25.290
But avoiding this foods if you
dont have allergies to them
00:25.290 --> 00:27.620
is unlikely to affect plazma symptoms.
00:27.620 --> 00:32.020
Some people with eczema have neclologies,
there is no nickel free diet for patients
00:32.020 --> 00:35.480
with nickel contact dermatitis, but
that is a very small portion of patients.
00:35.480 --> 00:39.038
Some of my patients are asking about
elimination diet per eczema, but
00:39.038 --> 00:41.340
i don't typically recommend them.
00:41.340 --> 00:45.560
An elimination diet is when you try to
completely cut out one or more foods
00:45.560 --> 00:50.120
in your diet like gluten or eggs or cow's
milk to see if it improves your symptoms.
00:50.120 --> 00:54.030
If you think you're having a reaction
to certain foods keep a food diary.
00:54.030 --> 00:56.630
If you notice you have flare ups
every time you have say milk or
00:56.630 --> 00:59.080
wheat talk to your dermatologist about it.
00:59.080 --> 01:02.550
You may have heard that it's a good
idea to eat an inflammatory diet
01:02.550 --> 01:06.140
such as lots of omega-3s and
antioxidants in whole foods.
01:06.140 --> 01:09.160
This hasn't been shown to relieve
the eczema symptoms per say, but
01:09.160 --> 01:11.650
it's just good general health advice.
01:11.650 --> 01:12.430
Bottom line, for
01:12.430 --> 01:16.690
most people making dietary changes won't
have a big impact on your eczema symptoms.
01:16.690 --> 01:20.492
It's never a bad idea to eat healthier,
and cut out sugar and processed foods, but
01:20.492 --> 01:22.785
don't expect this to work
miracles on your skin.
