According to the World Health Organization (WHO), nearly 60% of premature deaths worldwide are due to diseases directly linked to lifestyle—including diet. Science has proven that certain foods act like pressing the gas pedal on aging—both externally and internally. Let’s discover them together.
- Soft Drinks—the Sugar Trap in Shiny Packaging
Who among us hasn’t refreshed themselves at some point with a cold, fizzy drink? However, soft drinks—including beer, energy drinks and even flavored sparkling water—are true silent agers. The main problem is sugar. In an average 0.5-liter bottle of soft drink, there are 50 grams of sugar—that’s ten teaspoons! The World Health Organization recommends a maximum of 25 grams of sugar per day, meaning with just one drink, you consume double the amount.
Sugar boosts insulin levels, a hormone that among other things affects the condition of your skin. Excess sugar in the body triggers a process called glycation—in simple terms, this is when sugar sticks to proteins in our skin and destroys collagen, which is responsible for the firmness and elasticity of the skin. The result? Wrinkles, sagging skin, and a tired appearance.
In addition, studies by the American Heart Association have shown that women who regularly drink sweetened beverages are 30% more likely to develop diabetes, 26% more likely to develop heart disease, and have a higher risk of high blood pressure.
- Fried Food—a Fast Track to a Slow Heart
French fries, breaded steak, donuts and everything deep-fried in oil are among the foods that have always been associated with "thick blood" and "clogged arteries" in folk medicine. What sounds ancient is confirmed by science today. During frying at high temperatures, oils produce trans fats—substances proven to raise cholesterol, clog arteries, and cause inflammation in the body.
Trans fats are so dangerous that the European Union in 2021 limited them to a maximum of 2% of all fats in a food product, since they are directly linked to coronary disease, stroke and—let’s not forget—skin aging. Fried food promotes the production of free radicals—they're wild molecules in the body that damage cells and destroy the youthful appearance of skin.
Folk medicine has known the term “overcooked blood” for centuries, meant to describe inner restlessness and slow metabolism—which is exactly the feeling many of us have after a heavy fried meal.
- White Grains—Empty Grains, Empty Energy
White bread and white rice still make frequent appearances on our tables, but unfortunately these foods have almost no fiber, meaning our digestion suffers—and so does our skin. When food lacks fiber, it stays longer in our body, ferments, and produces toxins, which the body then eliminates—partially through the skin. This results in breakouts, dull complexion and overall tiredness.
These foods also have a high glycemic index, meaning they very quickly raise blood sugar levels. When sugar rises, the body releases more insulin, which—as already mentioned—leads to glycation and the loss of collagen.
No surprise, then, that a study published in the American Journal of Clinical Nutrition states that people who often eat whole grains are 19% less likely to develop chronic diseases and have better skin, fewer problems with constipation and more energy throughout the day.
- Red Meat—Powerful, but Inflammatory
Beef, pork, and lamb—the classic red meats—are full of protein and iron, but unfortunately also saturated fats, which promote inflammatory processes in the body. Folk medicine often spoke of “hot blood” in people who ate too much meat—and today we know they were right. Inflammation in the body also shows on the outside—as redness on the skin, enlarged pores, and dry patches.
Furthermore, red meat negatively affects collagen production, meaning the skin renews itself more slowly, sags faster, and is less able to retain moisture.
Interestingly, researchers from Harvard University found that women who eat more than 5 servings of red meat per week are 24% more likely to develop heart disease compared to those who eat it less often. The alternative? Fish, legumes, and nuts—which, according to tradition, have always been considered gentler foods that cool the body.
- Sweets—The Silent Thieves of Youth
Our grandparents knew how to distinguish between sweetness from nature and store-bought sweetness. Honey, dried fruit and homemade jam were allowed treats; everything else was considered an artificial indulgence. And they’re right. Refined sugar, as found in most candies, pastries, and chocolates, acts as an inner rust—as if you smeared sugar on your body and left it to slowly decay.
Every time you eat too much sugar, you trigger an inflammatory response in the body, which promotes breakouts, a tired skin look and the earlier appearance of wrinkles. This is also confirmed by a study from the University of California, where they found that a high sugar intake shortens the lifespan of cells—which means our body ages faster.
If you really can’t do without sweet treats, choose dark chocolate with 75% cocoa or more. Such chocolate is full of flavonoids—natural antioxidants that protect the skin from damage and boost blood circulation.
Youthfulness Isn’t Just a Face Cream ...
Ancient folk wisdom says that our skin speaks what our digestion thinks. And it’s true: if we eat food every day that burdens our body, sooner or later we’ll see it reflected on our face. Aging is a natural process, but it can be slowed down—not with expensive creams, but with simple everyday choices.
Are you curious about what it means to have naturally glowing skin, more energy, and better wellbeing? It’s no secret—just open your pantry, think a little, and remember what your grandmother would choose.
