Here’s something most people never connect: the food you eat can mess with your hormones, and those hormones can mess with your skin.
When you eat refined carbohydrates — think white bread, chips, sugary cereal, soda, candy — your digestive system breaks them down into sugar fast, which sends your blood sugar spiking. Your pancreas responds by pumping out insulin to deal with that spike. And here’s where it gets interesting: insulin is a hormone. When it surges over and over, research suggests it can trigger other hormonal shifts in your body — the kind that tell your skin to produce more oil. More oil means more clogged pores. More clogged pores means more acne.
This isn’t just internet speculation. There is a studied connection between high-glycemic foods and acne, and it traces back to how your body handles that blood sugar rollercoaster. That said, the science shows an association — researchers haven’t proven that diet causes acne in every person, and individual responses vary.
So what counts as a high-glycemic food? Basically anything that causes a steep, fast spike in your blood glucose — white rice, white pasta, most packaged snacks, sugary drinks, pastries. Whole foods like oats, brown rice, vegetables, and legumes digest more slowly and don’t cause the same dramatic spike.
The frustrating part? Diet doesn’t always come up in a typical dermatology visit. That’s not because diet doesn’t matter. It’s just not how most dermatology appointments are structured. You get about 10 minutes, they focus on topical treatments, and diet is rarely part of that conversation.
That doesn’t mean skincare products are useless. It means they might only be solving half the problem if your diet is constantly triggering the same hormonal response underneath.
If your breakouts are stubborn and you haven’t changed anything about what you eat, it’s worth paying attention to the pattern. Do you break out more after eating a lot of sugary or processed food? Do you notice your skin doing better during stretches where you’re eating more whole foods? Your own experience is data worth tracking.
You don’t have to go on some extreme diet to test this. Even cutting back on soda and heavily processed snacks for a few weeks is enough to notice a difference — or not. Either way, you’ll know more than you did before.
