Summary
Diet and longevity research has expanded significantly over the last decade, revealing key molecular pathways and dietary interventions. Further global collaboration is needed to advance healthspan science.
Area of Science:
- Nutrition Science
- Gerontology
- Bibliometrics
Background:
- Global population aging drives interest in diet for healthspan.
- Lack of bibliometric synthesis in diet and longevity research.
- Investigating research trends from 2015-2024.
Purpose of the Study:
- To conduct a bibliometric analysis of diet and longevity research.
- Identify publication trends, influential institutions, and research themes.
- Synthesize the state of the field over the past decade.
Main Methods:
- Bibliometric analysis of 2203 English-language articles (2015-2024).
- Keywords: "diet" and "longevity" in Web of Science database.
- Analysis using Web of Science tools, InCites, and VOSviewer.
Main Results:
- Publication and citation counts increased, peaking in 2021.
- US and China led productivity; UK institutions had high citation impact.
- Key themes: oxidative stress, autophagy, Mediterranean diet, calorie restriction, obesity, mortality.
- Model organisms like C. elegans and D. melanogaster were common.
Conclusions:
- Nutrition and longevity research is developing with novel molecular and translational topics.
- Highlights regional disparities and terminology variability.
- Recommends increased international cooperation and multidisciplinary frameworks for scientific advancement.

02:20Longitudinal Research
12.5K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

01:20Lifestyle Factors and Health
128
Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
Benefits of Physical Activity
Physical activity, whether through structured exercise or casual activities like walking, biking, or dancing, is a cornerstone of a...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

01:37Mitochondria
15.1K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

01:22PI3K/mTOR/AKT Signaling Pathway
4.0K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

02:59Cancer Prevention
6.3K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
