Most people eat high carbohydrate diets, including sucrose, fruit, grains, rice, and bread products. Recent evidence suggests that the carbohydrates in these diets (including sucrose and fructose) may be related to the development of Alzheimer’s and dementia. So avoiding sugar may be a way of protecting our brains.

Low sugar berries, like blackberries and wild blueberries,  appear to be a safe choice. They contain plant compounds that support brain health.  But fructose, even as it naturally occurs in fruit, can be dangerous. I wouldn’t say that it should be avoided entirely, but if you want to protect your brain health, it should be limited.

Fruit juice, for example, is loaded with fructose, and studies suggest that it can be as damaging as high fructose corn syrup to brain health.

Stop cooking with sugar, stop eating products made with sugar, and start limiting fructose, today.

  • From New Atlas: Excessive Sugar linked to Alzheimer’s in New Study
  • From Science Alert: We Just Got More Evidence for the Strange Link between Sugar and Alzheimer’s
  • From the Science Alert article: “While researchers continue to explore what those mechanisms could be, it’s becoming clearer that none of us, diabetic or otherwise, should assume diets high in sugar are necessarily harmless to both body and mind.”
  • From The Atlantic: The Startling Link Between Sugar and Alzheimer’s
  • From the Atlantic article: “A longitudinal study, published Thursday in the journal Diabetologia, followed 5,189 people over 10 years and found that people with high blood sugar had a faster rate of cognitive decline than those with normal blood sugar—whether or not their blood-sugar level technically made them diabetic. In other words, the higher the blood sugar, the faster the cognitive decline.”
  • From the Atlantic article: “The group that ate the most carbs had an 80 percent higher chance of developing mild cognitive impairment—a pit stop on the way to dementia—than those who ate the smallest amount of carbs. People with mild cognitive impairment, or MCI, can dress and feed themselves, but they have trouble with more complex tasks. Intervening in MCI can help prevent dementia.”
  • NOTE: Sugar from fruit (fructose) is considered just as dangerous from this perspective as table sugar (sucrose). 
  • Some items on the list have been shown to prevent degeneration of neural pathways.
  • Others appear to promote neurogenesis (the growth of new neurons and brain cells).
  • To me the evidence is convincing that the items on the list actually do have a beneficial effect. So I’ve incorporated them into my daily regimen.
