Summary: Diets high in processed foods, fast meals, and sweetened drinks accelerate natural aging, even in younger adults. Using genetic clocks, which track dna regulation changes over time, researchers used to study biological age. Individuals who ate a diet high in fruits and vegetables showed slower aging, which suggests that eating choices affect how quickly the brain ages.
The study also examined biological aspects, finding that shared biology, rather than childhood culture, played a vital role in the diet-aging connection. Diet remained an independent indicator of aging rate despite the addition of other lifestyle factors like tobacco and training.
Important information
- Diet and Aging: High intake of processed foods, fast foods, and sweet drinks is linked to accelerated natural aging.
- Epigenetic Clocks: Biological aging was quantified using mathematical models based on protein rules.
- Biological Control: Shared biology, rather than youth environment, influenced food’s impact on aging.

Humans do not always years medically at the same level as they do chronologically. More advanced natural ageing has been associated with higher rates of disease and mortality than historical aging.
A recent study found that a diet low in fruits and vegetables and high in red meat, fast foods, and sugar-sweetened sweet coffee was linked to an increase in natural aging yet in young adults.
The percentage of biological aging indicates the discrepancy between chronological age and biological age, i .e., whether a person is biologically older or younger than their chronological age.
Epigenetic watches can be used to determine natural aging. Epigenetic clocks are mathematical models created using machine learning techniques to generate genetic age predictions based on isopropyl groups that control the expression of genes.  ,
A study conducted by the University of Jyväskylä and the Gerontology Research Center looked at the relationship between diet and natural aging in young adults. The study participants were sisters between the age of 20 and 25.  ,  ,
According to the findings, diets with lower intake of fruits and red and processed meat, fast foods, and sugar-sweetened soft drinks were linked to faster natural aging.
Likewise, diets rich in vegetables and fruits and low in foods, fast foods, and sugary soft drinks were associated with slower natural maturity.  ,
‘ Some of the studied associations may also be explained by different lifestyle factors, such as real exercise, smoking, and system weight, as healthy and unhealthy lifestyle habits tend to cluster in the same individuals,’ says doctoral researcher , Suvi Ravi.
Even when other lifestyle factors were taken into account, eating still had a weak separate relationship with aging. ‘ ,
The study’s participants were sisters, so it was possible to examine the relationship between nutrition and natural period.
The connection between diet and aging in young adult is suggested by the results, not by a shared genetic background but rather by the sisters ‘ shared youth environment.
‘ But, this does not mean that a health-promoting diet would certainly benefit all,’ emphasizes Ravi.  ,
The research is a part of the Juho Vainio Foundation’s research project titled” The role of nutrition in the prevention of popular diseases.”
This sub-study utilized information from the FinnTwin12 research. The study included 363 twin sets and 826 personal twins in total. Participants in a meal frequency questionnaire provided information on the normal consumption regularity of 55 food items.  ,
The main investigator of this research, Suvi Ravi, is a member of the , GenActive research team.  , The , GenActive , team investigates biological and lifestyle elements that predict natural aging, wellbeing, and functional ability.
The group is led by Elina Sillanpää, Associate Professor of Health Promotion.  ,

Abstract
A study with sisters found that poor eating habits are related to accelerated natural aging in young age.
Background &, seeks
Suboptimal food raise mortality risk and illness. Epigenetic watches are algorithms that can predict health and longevity yet before disease symptoms become apparent in people. We looked into how nutritional habits and natural aging in young adult sisters relate to one another.
Methods
The data were drawn from the population-based FinnTwin12 study and consisted of twins aged 21–25 years ( n , = , 826 ). A meal speed questionnaire was used to assess food and beverage intake. The genomic clocks GrimAge and DunedinPACE were used to calculate natural aging. Hidden class analysis was used to identify eating patterns.
Using horizontal regression modeling at the individual level, within-twin set analyses to account for biological liabilities and shared parental confounders, the association between eating patterns and natural aging was investigated.
Results
Six dietary patterns were identified: 1 ) High fast food, low fruits and vegetables ( F&, V ), 2 ) Plant-based, 3 ) Health-conscious, 4 ) Western with infrequent fish, 5 ) Western with regular fish, and 6 ) Balanced average.
At the individual level, GrimAge motion was slower in the Plant-based, Health-conscious, and Balanced-average patterns compared to the High fast foods, low F&, V, and faster in the Northern with frequent fish design compared to the Balanced common, regardless of sex, nonalcoholic energy intake, smoking, and alcohol consumption.
After further adjustment for BMI and sports participation, the strengths of the associations modestly decreased, however, the difference between the Balanced-average and High fast food, low F&, V patterns remained significant.
The pace of aging ( DunedinPACE ) was slower in the Plant-based pattern compared to the High fast food, low F&, V and the Western with infrequent fish patterns after adjustment for sex, nonalcoholic energy intake, smoking, and alcohol.
When BMI and sports participation were included in the model, the effect sizes were attenuated and reached a non-significant level. The majority of the associations were carried out in the within-pair analyses for all twin pairs and dizygotic twin pairs, but the effect sizes were typically smaller for monozygotic twin pairs.
This suggests that genetics, but not a shared environment, may partially explain the observed associations between diet and biological aging.
Conclusion
Fast food, processed red meat, and sugary beverages are both associated with accelerated biological aging in young adults. When interpreting the findings, the clustering effect of lifestyle factors and genetic confounders should be taken into account.
