Alzheimer's Drivers
Four main factors contribute to Alzheimer's: inflammation, oxidative stress, glucose dysregulation, and lipid dysregulation.
The interplay of these factors, rather than a single cause, typically leads to the disease.
insights INSIGHT
Risk Factor, Disease, Event
Focus on minimizing plaque burden to reduce heart attack risk.
Aggressive risk factor management can delay atherosclerosis onset.
volunteer_activism ADVICE
Lipid Targets
Define your goal for risk reduction and tolerance for intervention.
Aggressive targets like ApoB < 0.6, LDL < 1.4, and non-HDL < 2 minimize risk.

Healthspan, healthy ageing, and chronic disease are pivotal topics in today's health discourse, emphasizing not just the length of life but the quality of those additional years. Focusing on healthspan means striving for a longer period of life free from disease and disability, which is increasingly important as global life expectancies rise. Healthy ageing involves adopting lifestyle habits that promote physical, mental, and social well-being throughout the lifespan, thereby reducing the risk of chronic diseases such as heart disease, diabetes, and neurodegenerative disorders.
Addressing chronic diseases risk requires a proactive approach centered on prevention and early intervention. By prioritizing healthspan and healthy ageing, individuals can significantly decrease the likelihood of developing chronic illnesses, leading to improved quality of life and reduced healthcare costs.
Sigma Nutrition Radio has consistently addressed these critical themes across many episodes. In this episode, we go back over some of the best episodes of 2024 in this area, including discussions on Alzheimer's, cholesterol-lowering medications, impact of exercise, and the debate about red meat.
