Module 2: Biohacking and Body Modification Flashcards
Modernization and aging theory
-suggests that families have little interest in caring for or supporting older adults
Social constructionism
-proposes that aging is a problem, not because of intrinsic issues such as physiological changes, but because certain societies define it as a problem
What is primary aging
-involves accumulation of macromolecule damage throughout the lifespan which ultimately impacts physical performance and fitness
What is secondary aging
-based on external factors such as diseases, environmental exposures, and lifestyle
Categories of biohacks
-optogenetics
-neurogenesis
-nutrition
-nutrigenomics
-calorie restriction
-CRISPR-Cas9
Optogenetics
-refers to an emerging technique that uses light to control neurons within the brain
-involves a light sensitive ion channel that opens in response to light which is then utilized to evoke neuron activity
What are the benefits of increasing neurogenesis in older adults
-plays a role in learning and memory
-reduce depression
-protect against Alzheimers
-increase memory capacity
-improved mood
Different nutrients that may affect primary aging
-omega-3 fatty acids
-fibre
-vitamin C
Omega-3 fatty acids
-help fight chronic inflammation, which makes your cells divide faster and prematurely wears down your telomeres
How much fatty acids should older adults include in diet
-1000 mg daily
Fibre
-also helps fight chronic inflammation by preventing insulin spikes
How much fibre should older adults have daily
-25 grams
Vitamin C
-helps protect cells from oxidative damage, which can shorten telomeres and helps to increase bone and muscle growth
Vitamin D deficiency
-seems to play a role in Crohns disease
What does nutrigenomics do
-influence gene expression
-modify cellular processes
Influence gene expression
-food you consume can have a direct or indirect influence on the human genome and thus influence the expression of genes
Modify cellular processes
-dietary patterns and/or specific dietary components may modify multiple cellular processes, including aging
What is calorie restriction
-diet-based biohack that focuses more on a behavioural change (eating less) than what you are actually consuming
Continuous calorie restriction
-refers to a sustained reduction of 20-50% of normal calorie intake
Intermittent calorie restriction
-involves phases of severe energy restriction and regular energy intake
What is CRONIES
-calorie restriction society
-voluntarily restrict their calories to 50% of a typical western diet
Effect of calorie restriction alone on primary aging
-significantly decreases cell damage associated with continued metabolic function
Effect of calorie restriction alone on secondary aging
-reduces weight and fat composition
-lowers blood pressure
-reduces inflammation
-improves insulin sensitivity
Effect of exercise alone on primary aging
-moderately decreases cell damage associated with continued metabolic function
