New study explores whether diet impacts accelerated aging by comparing identical twins on different diets; results underscore the importance of being mindful about nutrition into old age
A new study published in the Clinical Nutrition journal found a link between unhealthy eating habits and accelerated biological aging in late adolescence. Researchers examined twin pairs ages 18 to 35, with one consuming processed foods and sugary drinks while the other followed a balanced diet.
Research shows that individuals consuming predominantly processed foods, red meat, and sugary beverages while lacking fruits and vegetables demonstrated accelerated biological aging. This is manifested through cellular aging markers, chronic inflammation, and metabolic issues including elevated blood sugar and cholesterol.
Conversely, those following balanced diets featuring plant-based foods, lean proteins, and whole grains showed healthier biological aging markers, reduced inflammation, and improved metabolic health parameters.
The research also revealed that people with normal or low body weight who maintained poor eating habits showed more pronounced indications of biological aging than those following more nutritious diets.
To decelerate the aging process, researchers advocated for a diet abundant in:
-Fruits and vegetables: Rich in antioxidants and vital nutrients that defend against oxidative stress.
-Whole grains: Including legumes, whole wheat bread, oats, sweet potatoes and buckwheat, which promote overall health and longevity.
-Lean proteins: Such as fish, poultry and plant-based proteins like soy and tofu, which help preserve muscle mass and support cell repair.
They also recommended limiting:
Processed meats: Containing excessive unhealthy fats and preservatives that correlate with faster aging.
Sugary beverages: Associated with increased weight, inflammation and oxidative stress.
Fast food: Typically high in fats, sodium and processed sugars that negatively affect health over time.
Although genetic factors influence aging processes, the research emphasized that food choices substantially affect how quickly we age. Adopting healthier eating patterns can potentially slow biological aging mechanisms and enhance overall long-term health.
