Summary
Caloric restriction (CR) extends lifespan and delays aging by triggering adaptive stress responses. Promising alternatives include exercise and resveratrol, potentially mitigating age-related diseases.
Area of Science:
- Gerontology
- Nutritional Science
- Epigenetics
Background:
- Nutrition impacts individual and generational health, influencing chronic disease development and lifespan.
- Caloric restriction (CR) is known to extend lifespan and delay age-related decline across organisms.
Purpose of the Study:
- To explore the mechanisms by which CR promotes longevity and delays aging.
- To identify potential alternatives to CR for human application.
Main Methods:
- Review of studies on caloric restriction (CR) and its effects on aging.
- Analysis of molecular and cellular mechanisms, including epigenetic modifications and signaling pathways.
- Evaluation of CR mimetics such as exercise and resveratrol.
Main Results:
- CR induces adaptive stress responses, modulating epigenetic mechanisms and key aging-related signaling pathways (TOR, AMPK, p53, FOXO).
- These responses enhance cellular resistance to stress, promoting longevity and delaying age-associated diseases like cancer, diabetes, and neurodegeneration.
- Exercise and resveratrol show promise as practical alternatives to CR.
Conclusions:
- Caloric restriction enhances stress resistance and longevity through epigenetic and signaling pathway modulation.
- CR may delay the onset of major age-related diseases in humans.
- Exercise and resveratrol are identified as viable alternatives to CR for promoting healthspan.

01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
01:26Aging
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are not...
01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:15Drug Dosing: Geriatric Patients
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
