Does Cashew Trigger Pimples? – Lovely With Brains

Final Up to date on April 27, 2026 by Giorgia Guazzarotti

Does cashew trigger zits? I noticed this query in a Fb group final week and truthfully, it stopped me mid-scroll. As a result of my first thought was, “wait, cashews? Actually? We’re including cashews to the checklist of issues which can be apparently destroying our pores and skin now?”  As a result of right here’s the factor. Cashews have all the time been a kind of meals that will get a corridor go. Zinc, magnesium, wholesome fat, vitamin E – they’re actually in each “eat this for glowing pores and skin” article ever written. They’re the flowery nut.

The one you select of the combined bag first. So the concept they may be inflicting zits breakouts feels a bit backwards, like being informed your multivitamin is the issue. However lots of people with acne-prone pores and skin swear there’s a connection. And I get it. When your pores and skin is doing one thing you hate, you need solutions. So let’s truly get into it, as a result of the reality is extra fascinating than a easy sure or no, and by the top of this you’ll know precisely the place cashews sit in the entire diet-and-acne dialog.

What Causes Pimples?

Earlier than we put cashews on trial, it helps to know what zits truly is, as a result of a lot of the food plan recommendation floating round on-line skips this half completely and simply tells you to chop issues out with out explaining why. Pimples occurs when your hair follicles get blocked. Your sebaceous glands (mainly your pores and skin’s built-in oil glands) produce sebum, which is simply your pores and skin’s pure oil. Nothing improper with that, your pores and skin wants it. The issue begins when sebum mixes with useless pores and skin cells, will get caught inside a follicle, and creates the proper heat little surroundings for dangerous micro organism to go completely feral in there. That micro organism is named Cutibacterium acnes, and when your immune system clocks what’s taking place, it sends within the irritation troops. Therefore the crimson, indignant spot in your chin the day earlier than one thing essential.

Now the rationale food plan issues is that sebum manufacturing isn’t random. It’s pushed largely by your hormone ranges – particularly androgens, that are the hormones that inform your oil glands to supply extra. And sure meals mess with these hormones in methods which can be truly fairly effectively documented at this level. The 2 largest culprits the analysis retains coming again to? Dairy merchandise and excessive glycaemic meals. 

Cow’s milk (together with skimmed milk, which someway manages to be worse than full fats in some research) incorporates hormones that set off one thing known as IGF-1, which stands for insulin-like progress issue. IGF-1 mainly tells your sebaceous glands to enter overdrive. Excessive glycaemic meals (like white bread, white rice, fruit juice, sweet bars, something with excessive sugar content material) trigger a fast blood sugar spike, which shoots your insulin ranges up, which additionally raises IGF-1. Identical vacation spot, completely different route. This is the reason somebody who drinks a variety of cow’s milk or lives on quick meals and white rice may discover their pores and skin getting considerably worse, and why switching to one thing like almond milk or entire grains and candy potatoes can typically make a real distinction. Hold that in thoughts as we discuss cashews.

Is There A Connection Between Cashew And Pimples?

Right here’s the sincere reply: there are zero scientific trials particularly cashew nuts and zits. None. So anybody who tells you with whole certainty that cashews trigger zits is making it up a bit bit, and so is anybody who says they’re fully within the clear. What we will do (and what makes extra sense anyway) is have a look at what’s truly inside a cashew and see how that strains up with what we all know in regards to the causes of zits.

Excellent news first. Cashews have a very low glycaemic index, someplace round 22 to 25. That’s low. Meaning consuming them doesn’t trigger the blood sugar spike that sends your insulin ranges by way of the roof and kicks off that entire hormonal chain response. So the primary dietary pathway to zits? Cashews aren’t utilizing it. They’re additionally a strong supply of zinc, which is genuinely helpful for acne-prone pores and skin (zinc helps regulate oil manufacturing, has anti-inflammatory properties, and helps the pores and skin’s skill to heal). There’s precise analysis linking low zinc ranges to extra extreme zits. Cashews additionally include vitamin E, selenium, magnesium – all issues that help wholesome pores and skin reasonably than work towards it. To this point, so good. However right here’s the place it will get a bit extra difficult.

Do The Omega-6 In Cashews Trigger Pimples?

Cashews include omega-6 fatty acids. And there’s a rising physique of analysis suggesting that the stability between omega-6 and omega-3 in your food plan performs a big function in zits. An enormous examine printed within the British Journal of Dermatology in 2025 (and this one used genetic information from almost half 1,000,000 folks, so it’s not a small pattern) discovered {that a} larger ratio of omega-6 to omega-3 was related to a meaningfully elevated threat of zits, whereas larger omega-3 ranges had been protecting.

Now, cashews aren’t the worst omega-6 offender by an extended stretch. Vegetable oils, fried quick meals, protein bars, most processed snacks – these are much more vital sources. However cashews do have extra omega-6 than omega-3, and in case your general food plan is already skewed closely in that route – which most individuals’s diets are, as a result of fashionable consuming has gone fully off stability on this – then including a variety of cashews on prime of all the pieces else may theoretically push issues within the improper route. Just a bit. The problem is the entire image, not the cashews particularly.

And truthfully, if you happen to’re snacking on cashews which can be coated in salt, roasted in vegetable oil, or (God forbid!) coated in sugar or chocolate, you’re including variables that don’t have anything to do with the cashew itself. Plain, dry-roasted cashews in smart parts are a totally completely different factor to the salted, oily, caramelised form you get at Christmas.

Do Nuts Trigger Pimples?

Individuals throw nuts into one class and that’s probably not truthful as a result of they’re fairly completely different from one another:

• Peanuts (which aren’t even truly nuts, they’re legumes, however no matter) include compounds that may behave like androgens within the physique, which is a extra direct zits connection.
• Brazil nuts are extraordinarily excessive in selenium, which is nice in small quantities however lots of people eat too many pondering extra is healthier and it’s not. 
• Walnuts are genuinely excessive in omega-3 and have strong anti-inflammatory properties, in order that they’re in all probability probably the most skin-friendly possibility if you happen to’re actively coping with zits flare-ups.

Cashews sit comfortably in the course of all this. Not the only option if you happen to’re actually attempting to optimise all the pieces, but additionally nowhere close to the extent of, say, a whey protein shake or a glass of cow’s milk relating to triggering zits.

The Backside Line

Cashews aren’t inflicting your zits. In case your pores and skin is breaking out and also you’ve been consuming cashews, the cashews are virtually definitely not the primary occasion. Take a look at the remainder of your food plan first – are you consuming a variety of dairy merchandise, excessive sugar meals, quick meals, white bread, consuming fruit juice or alcoholic drinks often? These are the issues the analysis truly factors to. That stated, if you happen to’ve genuinely eradicated all the pieces else and you continue to suspect cashews are a private set off (which is feasible, as a result of pores and skin is annoyingly particular person), then minimize them out for six weeks and see what occurs. Reintroduce them slowly. Hold notes. That’s the one solution to know for positive. However please don’t hand over your cashews based mostly on a vibe. They’re one of many higher snacks on the market to your pores and skin, and the science, similar to it’s, largely backs that up.
