There are two main culprits that accelerate the aging process of our skin: sun exposure and advanced glycation end products (AGEs)Trusted Source. AGEs form when protein or fat combine with sugar. While these aging culprits aren’t 100 percent in our control, using sunscreen and taking mind of your overall diet can help with how our body protects and heals our skin.
And although minding your diet is easier said than done, it always helps to have a little reminder of how certain foods can affect your skin health. Our list can help with that.
But remember, every person is unique. Not everyone will benefit from eating raw, clean, or whole only. And regularly eating one or two of these foods won’t lead to less collagen and totally damage your skin. It’s straying away from a moderate diet that’s best for you that will change your health, skin or not.
So, go through this list with a grain of salt (pun not intended). Take the information that’s most helpful to you.
French fries can hit the spot — both in the satisfaction department and the AGE production department, as they’re fried and salty.
Foods fried in oil at high temperatures release free radicals that can cause cellular damage to the skin. Exposure to free radicals accelerates the aging process due to an action called cross-linking. Cross-linking affects DNA molecules and can weaken skin’s elasticity.
What’s more, consuming too much salt can draw water out from the skin and lead to dehydration. That may make your skin more prone to wrinkling.
When refined carbs integrate with protein, it causes the formation of AGEsTrusted Source. AGEs have a direct effect on chronic diseases as well as the aging process.
If you want: Try an alternative to traditional bread, such as sprouted grain breads that contain no added sugar. Sprouted breads also contain antioxidantsTrusted Source that are beneficial to the skin.
Sugar is one of the infamous contenders to unwanted skin concerns like acne. As mentioned above, sugar contributes to the formation of collagen-damaging AGEs.
When our sugar levels are elevated, this AGE processTrusted Source is stimulated. It’s sped up even more if sunlight is involved. So, instead of eating ice cream on the beach, opt for refreshing frozen fruit or a popsicle with no sugar added.
If you want: Reach for fruit or dark chocolate when craving something sweet. Blueberries, specifically, prevent loss of collagen (as shown in animal studiesTrusted Source).
Take it easy with that butter knife. Older studies have shown that those who don’t consume margarine or butter have less skin damage and wrinkles than those who do.
And the science checks out: Margarine is worse than moderate amounts of real butter due to the fact that it’s high in partially hydrogenated oils. These trans fatty acids make skin more vulnerable to ultraviolet radiation, which can damage skin’s collagen and elasticity.
If you want: Swap butter for olive oil or smear avocados, rich in anti-aging antioxidants, on toast instead.
Hot dogs, pepperoni, bacon, and sausage are all examples of processed meats that can be harmful to the skin.
These meats are high in sodium, saturated fats, and sulfite, which can all dehydrate the skin and weaken collagen by causing inflammation. For inexpensive protein options, swap processed meats for eggs or beans.
If you want: Opt for leaner meats like turkey and chicken. These meats are packed with protein and amino acids that are essential in the natural formation of collagen.
Got mixed feeling about dairy? Science does, too.
Some have seen positive skin changes from dropping dairy. Others have seen no significant difference at all.
It all depends on the person. For some, dairy may increase inflammation in the body, which leads to oxidative stress. Oxidative stressTrusted Source is one of the main causes of premature aging.
Diets low in dairy products may protect sun-exposed skin from wrinkling.
What soda and coffee do to your health have more to do with sleep than skin. First, both are high in caffeine, which, if you drink frequently throughout the day to night, may affect your sleep.
If you want: If you’re concerned about the sugar content, take a look at how much you’re drinking. See if you can decrease the amount or make swaps, like having golden milk instead of coffee. Turmeric, the main ingredient in golden milk, is rich in antioxidants and one of the most powerfulTrusted Source anti-aging compounds around.
Alcohol can cause a host of problems when it comes to the skin, including redness, puffiness, loss of collagen, and wrinkles.
Alcohol depletes your nutrients, hydration, and vitamin A levels, all of which have a direct impact on wrinkles.
Vitamin A is especially important in regards to new cell growth and the production of collagen, ensuring that skin is elastic and wrinkle-free.
If you want: Drink in moderation. That’s one drink per day for women and two for men. Make sure you’re well-hydrated with water. Try experimenting with some fun and creative mocktail recipes as well.
Some polyunsaturated oils high in omega-6 fatty acids, like corn or sunflower oil, can cause harmful free radicals and can increase inflammation levels. If you’re frying or using high heat every day, that adds up.
But this doesn’t mean that all oils are unhealthy. When it comes to oils and wrinkle prevention, opt for monounsaturated fats to help keep the skin hydrated.
If you want: Swap vegetable oils for olive oil. It’s rich in antioxidants, vitamin E, and phytosterols, and reduces inflammation.
While rice cakes are usually touted as a good snack, this isn’t the case for the skin.
If you want: For an anti-aging snack, try hummus with red bell pepper strips. Red bell peppers are high in vitamin C, making them great at producing collagen. Chickpeas are chock-full of skin-healthy antioxidants, too.
Many people are surprised to hear that agave can contain more fructose than high fructose corn syrup.
As we know from above, fructose breaks down collagenTrusted Source much quicker than regular sugar, which can speed up wrinkle formation.
If you want: Since lipoic acid may prevent the collagen-damaging effects from fructose, if agave is the only sweetener you can have, remember to include lots of Brussels sprouts (which are high in lipoic acid) in your diet.
