Are autoimmune diseases becoming more common? Yes…and it may have to do with environmental triggers. Find out why in Experience Life magazine: experiencelife.lifetime.life/article/are-au…


For those with diabetes, avoiding added salt is about more than blood pressure. Excess salt can trigger pathways that worsen insulin resistance and impair glucose regulation.

The link between triglycerides and Alzheimer’s is complex. Elevated midlife levels may raise risk, while higher late life levels could be protective. What is clear is that triglycerides are tied to diabetes and heart disease, so monitoring them is key.


Artificial sweeteners are not harmless. Research shows they may disrupt the gut microbiome, threaten metabolism, and may even impact brain health. Agave, often seen as natural, is about 70% fructose and is one of the most concerning sweeteners of all.


Eggs may have been misunderstood. A new study following 1,000+ older adults found that eating just one or more eggs per week was linked to a 47% lower risk of Alzheimer’s. Choline and omega-3s in eggs could be the reason. Sometimes the simplest foods make the biggest…


Over a decade ago in Grain Brain I warned about sugar and cognitive decline. New research now shows that even natural sugars like those in fruit and milk can affect brain health when over-consumed. This is not just a metabolic issue, it is a cognitive one. Learn more:…


Ultra processed foods are not just empty calories. Studies link them to faster cognitive decline, reduced gray matter, and higher dementia risk. Choosing whole, nutrient rich foods is one of the best ways to protect your brain.


Creatine is not just for athletes. Research shows that just 5g daily can boost memory, focus, and mental clarity, support brain energy, and may even help protect against age related cognitive decline.


Sugar is more than a dietary issue. It is a powerful driver of brain decline. A study of 158,000 people over nearly a decade found higher sugar intake significantly increased dementia risk, even from foods often seen as “healthy.” Learn more: drperlmutter.com/powerful-threa…


Supplements can be powerful, but they cannot replace the basics. Nutrition, sleep, movement, stress management, and mindset form the foundation of brain and body health. Supplements should support, not substitute.


Your meals do more than fuel you. They shape how your brain and body perform. Nutrient rich, anti inflammatory foods can boost focus, energy, and long term health.


What is the best type of exercise? Research following thousands of people over 10 years shows the greatest benefits come from variety. Resistance training, aerobic activity, and flexibility work each play a role in lowering inflammation and boosting brain health.


Fascinating presentation from @PaulStamets at #UNGA2025 on how fungal mycelium can support ecosystems, protect honey bees, and even benefit human health. Watch here: webtv.un.org/en/asset/k15/k…


Why do some people get sick more often than others? It comes down to immunometabolism, the profound link between our metabolic state and immune resilience. Blood sugar, insulin sensitivity, and overall metabolic health directly shape how well our immune system responds.


Type 2 diabetes more than DOUBLES Alzheimer’s risk. In my free Diabetes Guide, I share simple, actionable, science-backed ways to balance your blood sugar and reduce your risk. Get it here: drperlmutter.com/guides/focus-o…


1 in 5 American teens now has prediabetes. That is not a typo. It may be silent, but it is sneaky. And it puts brain health at risk. Better food choices, deep restful sleep, and daily movement can restore insulin sensitivity and protect the brain.


Even mild elevations in blood sugar can raise your risk for cognitive decline. Research links type 2 diabetes to impaired neurogenesis, inflammation, and brain barrier damage. Protecting brain health starts with blood sugar balance. drperlmutter.com/diabetes-and-r…
