Centenarians, those who live to or beyond 100 years, are often studied to unlock the secrets of longevity. Recent research has examined their dietary habits and medication usage, offering insights into the lifestyles that contribute to healthy aging. The review, analyzing studies from the past two decades, indicates that centenarians maintain balanced diets predominantly comprised of carbohydrates, proteins, and fats. Notably, more than half adhere to diverse diets with limited preference for salty foods, aligning with lower mortality and functional decline rates.
Medication patterns also play a crucial role, with many centenarians using antihypertensives and cardiovascular drugs, averaging about 4.6 medications. Health issues such as hypertension and dementia are prevalent, yet these elders maintain a surprisingly active lifestyle. Physical activities, sufficient sleep, and low rates of smoking and drinking further delineate their health-conscious behavior. Importantly, the research underscores the significant influence of rural living and good sleep hygiene on longevity.
This comprehensive review not only provides a statistical insight into the centenarians’ health regimes but also emphasizes the importance of dietary and lifestyle choices in extending life quality and span. Understanding these patterns helps frame better aging strategies and healthcare policies, potentially inspiring individuals and communities towards healthier living practices.

Centenarians represent a phenomenon of successful aging. This systematic review aimed to understand lifestyles and health practices, focusing on diet and medication use for healthy longevity in community-based adults 95 years or over. Medline, CINAHL, Scopus, and gray literature were searched from 1 January 2000 to 10 December 2022. Study quality was assessed using the Modified Newcastle-Ottawa Scale (mNOS). Pooled prevalence [%; 95% confidence interval] for categorical variables and pooled mean for continuous variables were estimated for demographics, weight status, lifestyle factors, medications, and health conditions. Of 3392 records screened, 34 studies were included in the review, and 71% (24/34) met the 6/8 criteria in mNOS. Centenarians/near-centenarians' ages ranged from 95 to 118 years, with 75% (71-78%) female and 78% (68-88%) living in rural areas. They had an overall healthy lifestyle: current smoking (7%; 5-9%), drinking (23%; 17-30%), normal weight (52%; 42-61%), overweight (14%; 8-20%), physical activity (23%; 20-26%), and sleep satisfaction (68%; 65-72%). Diet averaged 59.6% carbohydrate, 18.5% protein, and 29.3% fat; over 60% consumed a diverse diet, and < 20% preferred salty food, contributing to lower mortality risks and functional decline. About half used antihypertensives (49%; 14-84%) or other cardiovascular drugs (48%; 24-71%), with an average of 4.6 medications. Common health issues included impaired basic activities of daily living (54%; 33-74%), hypertension (43%; 21-65%), and dementia (41%; 23-59%). The findings of this systemic review underscore the pivotal role of dietary practice and weight management in healthcare strategies to promote healthy ageing. It also recognises rural living styles and sleep hygiene as potential factors contributing to healthy longevity.
