Age spots—those flat, tan, or brown patches that tend to show up on sun-exposed areas like the face, hands, and shoulders—are often associated with years of sun exposure. But what you put on your plate might also play a part. Dietitians are increasingly pointing to certain foods that could encourage hyperpigmentation by promoting inflammation and oxidative stress in the skin.
While no single food will automatically cause age spots, a pattern of eating that is high in certain pro-inflammatory compounds can make skin more vulnerable to discoloration over time. Here are four categories of foods that dietitians say are worth watching if you are concerned about age spots.
Sugary Foods and Refined Carbohydrates
High-sugar foods—think pastries, white bread, sugary cereals, and soda—can trigger a process called glycation. This is when excess sugar molecules bind to proteins like collagen and elastin in the skin, forming advanced glycation end products (AGEs). Those AGEs contribute to stiff, less resilient skin and can worsen hyperpigmentation, including age spots. Dietitians often advise focusing on whole grains, vegetables, and low-glycemic fruits to keep blood sugar steadier and reduce glycation.
Processed Meats and Fried Foods
Bacon, sausage, deli meats, and anything deep-fried tend to be high in advanced glycation end products themselves—especially when cooked at high temperatures. These external AGEs add to the body's internal load and can ramp up inflammation. Over time, chronic low-grade inflammation makes skin more prone to uneven pigmentation. Choosing lean proteins like grilled chicken, fish, or plant-based options and using gentler cooking methods like steaming or baking can help lower that inflammatory burden.
Highly Refined Vegetable Oils
Oils such as sunflower, corn, soybean, and cottonseed are often high in omega-6 fatty acids. While some omega-6 is necessary, the typical Western diet tilts heavily toward omega-6 and away from anti-inflammatory omega-3s. This imbalance can promote systemic inflammation, which may accelerate skin aging and discoloration. Dietitians recommend replacing these oils with extra-virgin olive oil, avocado oil, or other sources of monounsaturated and omega-3 fats.
Excessive Dairy (for Some People)
Dairy is not universally problematic, but for certain individuals—particularly those with a sensitivity or a tendency toward acne-type hyperpigmentation—cow's milk can trigger inflammation and darkened spots. Some research links dairy consumption to increased insulin-like growth factor 1 (IGF-1), which can stimulate sebum production and inflammatory responses in the skin. If you notice that cheese, milk, or yogurt seems to coincide with new dark patches, a short elimination trial under the guidance of a dietitian might be worth exploring.
A quick note: The biggest trigger for age spots remains ultraviolet light. Eating well supports skin health, but it cannot replace daily sun protection.
Beyond cutting back on these foods, dietitians suggest loading up on colorful produce rich in antioxidants—berries, leafy greens, bell peppers, and tomatoes—to help protect skin from oxidative damage. Vitamin C, vitamin E, and polyphenols found in plants can all support more even skin tone over time. Staying hydrated and getting enough sleep also matter; both help the skin repair and regenerate.
If you are already seeing age spots, a nutrient-dense diet may help prevent new ones from forming as readily. But remember that genetics and cumulative sun history play major roles. Using broad-spectrum sunscreen, wearing protective clothing, and avoiding tanning beds are still your first line of defense. Talk with a registered dietitian who specializes in skin health if you want personalized guidance on which dietary changes could make the biggest difference for your complexion.
