This Diet Can Protect You from 32 Chronic Diseases, Suggests a New Study
A recent study published in Nature Communications leveraged data from the UK Biobank to explore the link between nutritious eating habits and the prevalence of 48 distinct chronic diseases in adults living in communities.
The study highlights the critical role of aging as a primary factor in the development of non-communicable diseases (NCDs), which have contributed significantly to the increase in mortality rates from 2007 to 2017. Identifying effective preventative measures to support healthy aging is thus essential.
The research also underscores the importance of addressing modifiable factors related to chronic conditions not directly linked to aging, such as dyspepsia and irritable bowel syndrome. These conditions are prevalent and place a substantial burden on healthcare systems.
Evidence indicates that adopting a healthy lifestyle can reduce the risk of chronic diseases and extend life expectancy. Diet, in particular, plays a vital role and can be optimized to mitigate or forestall these chronic ailments.
Adhering to specific dietary patterns, including the Healthy Eating Index (AHEI-2010), Healthful Plant-based Diet Index (HPDI), and the Mediterranean diet score (AMED), has been associated with a reduced risk of cardiovascular diseases, certain cancers, and diabetes.
Nevertheless, the relationship between these dietary patterns and various other chronic conditions, such as endocrine disorders, skin conditions, eye diseases, and chronic kidney disease (CKD), is still not fully understood.
This investigation utilized the UK Biobank data to examine the connection between four prevalent dietary scores and the risk of numerous chronic conditions, determining which dietary pattern offers the most accurate predictions for chronic diseases.
The study excluded individuals with incomplete dietary data or extreme energy intakes, resulting in a final sample of 121,513 participants, 55.9% of whom were women, with ages ranging from 30 to 75 years and an average age of 59.
The results revealed that older, well-educated non-smokers were more likely to score higher on dietary assessments. Women tended to have higher AMED or AHEI-2010 scores, while men were more likely to have higher anti-empirical Dietary Inflammatory Index (AEDII) scores.
Key Findings:
- A higher AMED score correlated with a reduced risk of 32 chronic diseases.
- A higher AHEI-2010 score was linked to a reduced risk of 29 chronic diseases.
- A higher HPDI score was associated with a lower risk of 23 chronic conditions, spanning various disease categories.
Conversely, a high AEDII score was linked to an increased risk of psychoactive substance abuse and alcohol use disorder, but a decreased risk of 14 other chronic diseases. The AMED diet, rich in beneficial foods like fish, legumes, nuts, vegetables, and fruits, demonstrated the most comprehensive protective effects against chronic conditions.
Conclusions:
Despite its insightful findings, the study acknowledges certain limitations, such as potential errors in self-reported data from the UK Biobank and the absence of causal relationships in the analysis. Additionally, the generalizability of the results may be limited due to the predominantly Caucasian participant demographic.
In summary, the study supports the notion that adhering to healthy dietary patterns, particularly the AMED, can significantly reduce the risk of numerous chronic diseases, underscoring the power of nutrition in disease prevention.
