Whether you’re more concerned about the fine lines, memory lapses, or sexual function… we can’t do anything about the aging process unless we understand WHY and HOW it is happening. In this post, we’ll dive into the theories of aging—scientific ideas that explain why we age and what contributes to the process.
So let’s take a look at 7 theories of aging:
1️⃣Free Radicals
Free radicals create oxidative stress to damage cellular DNA. They increase with exposure to cigarette smoke, air pollution, and unhealthy foods.
What can we do? Loading up on antioxidants from fruits, vegetables, herbs, and supplements.
2️⃣“Inflammaging”
Changes in the immune system can shift the body into a state of low-grade and chronic inflammation, also called “inflammaging.”
What can we do? Eat an anti-inflammatory diet, exercise, and minimize stress.
3️⃣Protein Cross-Linking
Protein cross-linking happens when sugar forms a chemical bond with proteins. It leads to stiffening of the blood vessels, stiffening of the joints, loss of skin elasticity, and other signs of aging.
What can we do? Keep blood sugars stable and minimize sugary food and drinks.
4️⃣Heat Shock Proteins
Heat shock proteins protect cells from damage under stressful conditions, but they decrease with age.
What can we do? Anything the body perceives to be mildly stressful, like exercise, cold showers, and fasting.
5️⃣Telomeres
Telomeres are sections of DNA at the end of each chromosome that protect it from unraveling. Scientists consider shortening telomeres to be a hallmark of aging.
What can we do? Eat a plant-rich diet, exercise, and minimize stress.
6️⃣Stem Cells
Adult stem cells help old and damaged tissues regenerate by replacing damaged cells.But their ability to do so declines with age.
What can we do? Cell-based therapies are an emerging area of regenerative medicine.
7️⃣Hormones
From declining levels of growth hormone to all the changes associated with menopause and andropause, hormones can contribute to many of the signs of aging.
What can we do? Hormone replacement is an option but should be considered only under the supervision of a healthcare professional.
