ANTI-AGING: Eating a high healthy-fat, low-carb, moderate protein diet

  • Recent studies have shown that high fat, low carb diets may protect against Alzheimer’s.
  • WebMD article: High Fat, Low Carb Diets May Help Alzheimer’s
  • From the WebMD article: “A new study shows mice bred to develop Alzheimer’s disease showed less of the brain-clogging plaques associated with the disease when they were fed a high-fat, low-carbohydrate diet than mice fed a standard low-fat, high-carbohydrate diet.”

  • Some fats have been shown to be good for the brain. These BRAIN-HEALTHY FATS include DHA and EPA (from fish or krill oil) and MCT OIL (from coconuts or palm).
  • 60% of the brain is made up of fat.  The fatty acid DHA (found in fish, krill and some other seafood) comprises 40% of the polyunsaturated fatty acids in the brain.
  • According to The Journal of Nutrition: “Our recent literature review found 9 epidemiological studies associating increased fish consumption with reduced risk for dementia, including AD. Furthermore, 8 out of 10 studies found that higher blood (n-3) fatty acids were associated with reduced cognitive decline”
  • Another fatty acid from fish, EPA, has also been shown to prevent memory loss. See article: EPA Fish Oil Prevents Memory Loss, Offering Hope For Alzheimer’s Patients
  • To get both EPA and DHA, you can take fish oil or krill oil, or eat fatty fish. Fish low on the food chain such as sardines are an ideal source, because they are much lower in contaminants such as mercury and PCBs. Pacific salmon is also high in fatty acids and low in contaminants.
  • There’s some anecdotal evidence that MCT OIL (from coconuts) may prevent or reverse symptoms of dementia. This article relates one doctor’s experience using MCT with her husband, who was suffering from severe Alzheimer’s: Dr. Mary Newport, Alzheimer’s Disease: What If There Was A Cure?
  • Of course, people should also avoid certain fats, such as TRANS FATS. And there’s evidence that some oils which have been promoted as healthy may actually be harmful.

  1. I’ve found it easy to add EPA, DHA and MCT oils to my diet.
  2. I eat sardines three or four times a week, and eat salmon roe on the other days.
  3. I take fish oil and krill oil as supplements. The best kind of fish oil I’ve found is VIVA, which contains fish oil in a triglyceride form.
  4. I take MCT oil as a supplement, and also cook with it. (If I’m feeling tired after a day of teaching, but have more classes coming up, taking some MCT can make me feel mentally alert again.)
