Why Your Diet is Making You Look Older
And what you can do about it!
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.
Inadequate Protein Intake
Our body needs protein to produce collagen, a structural protein that helps keep our skin firm and supple. Our bodies produce less collagen as we age, leading to wrinkles and sagging skin. A diet low in protein can further accelerate this process as the body lacks the building blocks to repair and replace lost collagen.
A study by J.L. Krok-Schoen and colleagues examined the protein intakes and associated dietary patterns and functional limitations in an aging population. The study, conducted using data from the National Health and Nutrition Examination Survey, investigated the relationship between protein intake and functional outcomes in older adults.
They analyzed data from 11,680 non-institutionalized adults divided into three age groups: 51-60, 61-70, and 71 years and older. Dietary recalls were collected using the multiple pass method, and participants were categorized based on whether they met the recommended protein intake of 0.8 g/kg/d. Data analysis was weighted to create a nationally representative sample.
They found that dietary protein intakes were significantly lower in older age groups, with up to 46% of the oldest adults not meeting the recommended intake. Those not meeting the protein recommendation also had significantly lower overall diet quality and were likelier to take other nutrients below recommended levels. Additionally, these individuals had significantly more functional limitations, with grip strength being noticeably lower in those over 70 years old.
As you can see from the study, inadequate protein intake can have detrimental effects on our health and functional abilities as we age. Thus, ensuring sufficient protein intake through a well-balanced diet is crucial for slowing aging.
Alcohol Intake
We all know that excessive alcohol consumption is harmful to our health. But did you know it can also accelerate the aging process? Studies have shown that chronic alcohol intake leads to DNA damage and oxidative stress, both of which contribute to aging.
A study by Drew R. and colleagues investigated the association between alcohol consumption and epigenetic age acceleration in young adults. The study was conducted on a subset of participants from the Coronary Artery Risk Development in Young Adults Study, who underwent DNA methylation profiling.
The participants' cumulative alcohol consumption and recent binge drinking were assessed through questionnaires. The researchers also used blood samples to analyze four measures of age-related epigenetic changes using the Illumina Methylation EPIC Beadchip.
The study found that liquor and total alcohol consumption were associated with a more excellent GrimAge acceleration per additional five alcohol years. On the other hand, beer and wine consumption did not show significant associations with epigenetic age acceleration. Recent binge drinking and the number of days of binge drinking were also found to be associated with higher GrimAge acceleration.
The findings suggest that cumulative liquor and total alcohol consumption, as well as recent binge drinking, can alter age-related epigenetic changes captured by GrimAge acceleration. These results highlight the potential negative effects of excessive alcohol intake on healthy aging and emphasize the importance of lifestyle modifications in promoting healthy aging.
Overall, this study adds to the growing body of evidence linking alcohol consumption to accelerated aging and provides valuable insights for future research on lifestyle interventions for healthy aging. So, if you want to maintain a youthful appearance and avoid premature aging, it may be wise to limit your alcohol intake.
Refined Carbohydrates
Like sugary foods, white bread, pasta, and other refined carbs have a high glycemic index, meaning they cause a rapid increase in blood sugar levels. Like sugar, these foods can lead to glycation, the process by which sugar molecules attach themselves to proteins and form harmful new compounds called advanced glycation end products.
Advanced glycation end products can damage collagen and elastin in our skin, leading to wrinkles and sagging. A study by Mardia L. and colleagues investigated the effects of a high intake of refined carbohydrates on inflammation and insulin resistance in children. It was found that, while mean macronutrient intake was excessive, micronutrient intake was deficient.
The study analyzed a cross-sectional sample of 229 children from Mexico City. Anthropometric measurements, 24-hour recall questionnaires, and blood samples were obtained to measure serum insulin, glucose, calcium, magnesium, 25-OHD3 (vitamin D), C-reactive protein, leptin (a satiety hormone produced by fat cells), adiponectin (a hormone involved in regulating glucose levels), and fatty acids in red blood cells.
Results showed that while overall macronutrient intake was excessive, micronutrient intake was deficient. Central obesity and magnesium-deficient diets were found to be determinants of inflammation, while high intake of refined carbohydrates was a risk factor for insulin resistance, independently of central adiposity.
The study highlights the harmful effects of high consumption of refined carbohydrates on our health, specifically regarding aging. Refined carb-rich diets can lead to inflammation and insulin resistance, ultimately resulting in wrinkles and sagging skin.
Maintaining a balanced diet that includes essential micronutrients like calcium, magnesium, vitamin D, and omega-3 fatty acids is critical to protect against these harmful effects. So, next time you reach for that sugary snack or bowl of pasta, remember that it may affect your waistline and contribute to premature aging.
Choose whole grains and nutrient-dense foods for a healthier and more youthful appearance.
Bottom Line!
Our diet plays a crucial role in how we age. Adequate protein intake is essential for maintaining muscle mass and functional abilities as we age. Excessive alcohol consumption and high intake of refined carbohydrates can accelerate the aging process by causing inflammation, insulin resistance, and damaging our skin's collagen and elastin.
A well-balanced diet that includes essential nutrients and avoids excessive alcohol intake and refined carbs is crucial to promoting healthy aging. So, fill your plate with plenty of fruits, vegetables, whole grains, lean protein sources, and healthy fats for a youthful appearance inside and out.
Remember that it's never too late to make positive changes in your diet and start prioritizing your health for a long and vibrant life. Aging is inevitable, but how we age is up to us!
Let's age gracefully by checking what we eat!
