Are you blaming it on genetics or the natural process of getting older? Well, what if I told you that your diet could be a primary culprit in making you look older than your actual age? I found some interesting studies about this, which I’ll dive into and give you the take-aways.
The food choices we make every day affect our overall health and significantly impact how we age. In this article I’ll share the science behind this and understand why your diet makes you look older. Also, I’ll share some tips on how you can make dietary changes to slow down the aging process and maintain a youthful appearance.
The Role of Inflammation
One of the main reasons our diet affects how we age is inflammation. Inflammation is our body's natural response to injury or infection, but excessive and chronic inflammation can lead to various health issues, including accelerated aging.
Now, what does this have to do with our diet? Certain foods can trigger an inflammatory response in our bodies, while others can help reduce inflammation. For example, processed and high-sugar foods cause inflammation, while foods rich in antioxidants and healthy fats have anti-inflammatory properties.

High Sugar Intake
Sugary foods and drinks are an everyday indulgence in modern diets, but they can also have adverse effects on our skin. High sugar intake can lead to glycation, where sugar molecules attach to proteins in our body, forming harmful compounds that contribute to aging.
A study by Dorothy T. and colleagues examined the association between dietary patterns and epigenetic aging in a diverse group of midlife Black and White women in the US. The study involved 342 participants who completed a 3-day food record to assess their diet quality, including intakes of essential nutrients and added sugar.
They also used a second-generation epigenetic clock marker called GrimAge2 to calculate the participants' epigenetic age.
Based on their analysis, the study found that high sugar intake was significantly associated with accelerated epigenetic aging. This means that consuming too much-added sugar can contribute to faster cellular aging compared to chronological age.
On the other hand, healthier dietary patterns, as indicated by higher scores in established nutrient indices like the Alternate Mediterranean Diet and Alternate Healthy Eating Index -2010, were associated with younger epigenetic age.
This suggests that promoting diets aligned with chronic disease prevention recommendations and low-added sugar consumption may support slower cellular aging in midlife women. This study highlights the importance of mindful eating and its impact on our health at a cellular level.
Therefore, the study proves that high added sugar intake can accelerate epigenetic aging in midlife women, while healthier dietary patterns may support slower cellular aging. These findings emphasize the importance of promoting healthy eating habits to maintain genomic stability and preserve overall health.
So, avoiding high sugar intake and focusing on consuming nutrient-rich foods for a healthier and youthful body is imperative.
Processed Foods and Trans Fats
Processed foods, such as fast food, chips, and baked goods, often contain trans fats and other unhealthy oils. These fats can trigger inflammation in the body, which damages the skin’s structural proteins and reduces its ability to retain moisture, making you look older.
A fascinating study by Naomi G. and colleagues investigated the effects of trans fatty acids on endothelial inflammation and nitric oxide production. The study involved treating human endothelial cells with three types of trans fatty acids commonly found in processed foods: Elaidic acid, Linoelaidic acid, and Transvaccenic acid.
After this, they measured activation levels for the Nuclear factor kappa B protein, which is known to play a role in inflammation. They also measured insulin signaling and nitric oxide production, essential for maintaining healthy endothelial function.
The results showed that Elaidic acid and Linoelaidic acid significantly increased the activation of Nuclear factor kappa B and impaired insulin signaling and nitric oxide production. On the other hand, Transvaccenic acid did not have these negative effects.
Moreover, Elaidic acid and Linoelaidic acid also increased the production of superoxide, which has been linked to the activation of Nuclear factor kappa B. This suggests that these trans fatty acids induce inflammation through superoxide production.
The study found that different types of trans fatty acids have varying effects on endothelial function and inflammation. Specifically, Elaidic acid and Linoelaidic acid were associated with increased inflammation and reduced nitric oxide production in endothelial cells, while Transvaccenic acid did not cause these adverse effects.
These findings highlight the importance of avoiding processed foods high in trans fats for maintaining healthy skin and overall health.
