Dr. Richard Johnson, a Professor at the University of Colorado Denver, is renowned for his groundbreaking research on fructose and its links to obesity and Alzheimer’s. In this discussion, he reveals how Alzheimer’s is now dubbed 'type 3 diabetes' due to its ties with insulin resistance. Johnson proposes a radical new hypothesis connecting high fructose intake to cognitive decline. With insights into the evolution of our sugar consumption and its harmful effects, he shares compelling dietary strategies to combat these risks and improve brain health.
The link between Alzheimer's disease and insulin resistance highlights the importance of metabolic health in cognitive decline prevention.
Dr. Johnson's hypothesis emphasizes the detrimental effects of excessive fructose consumption on brain health and memory function.
Understanding the distinction between Alzheimer's and dementia is crucial for identifying early symptoms and seeking appropriate interventions.
Deep dives
Fructose and Cognitive Decline
Diet, particularly the consumption of fructose, significantly impacts cognitive health and is linked to Alzheimer's disease. Studies indicate that fructose levels in the brains of Alzheimer's patients are five to six times higher compared to those without the disease, leading to cognitive dysfunction. Foods high in simple sugars, such as pancakes, bread, and cereals, can exacerbate these issues by promoting inflammation and insulin resistance, which are key factors in the development of Alzheimer's. Therefore, limiting sugar intake is crucial for maintaining cognitive function and potentially preventing the onset of Alzheimer's.
Distinguishing Alzheimer's from Other Forms of Dementia
Alzheimer's disease is often confused with dementia, though it has distinct characteristics. Dementia serves as a broad term encompassing various cognitive impairments, while Alzheimer's is specifically associated with physical changes in the brain, including the formation of amyloid plaques and tau tangles. Cognitive decline typically begins with recent memory loss, making it critical to identify early symptoms for potential reversibility. Understanding the differences can aid in seeking appropriate interventions for cognitive decline.
The Role of Insulin and Inflammation
The relationship between Alzheimer's disease and metabolic health is underscored by findings linking insulin resistance and inflammation to cognitive decline. As insulin resistance develops in the brain, the uptake of glucose, a primary fuel source, diminishes, leading to reduced energy production crucial for neuronal function. Inflammation exacerbates these changes, contributing further to neuronal damage. Addressing metabolic health through dietary adjustments may lower the risk of Alzheimer's and aid in managing its symptoms.
Dietary Adjustments for Prevention
Emphasizing dietary changes is vital for reducing the risk of Alzheimer's disease, primarily by minimizing carbohydrate and sugar intake. Substituting high-fructose and high-glycemic foods with vegetables and healthy fats creates a more protective dietary environment. Although completely eliminating sugar and refined carbohydrates might be unrealistic for most, implementing gradual reductions can yield positive results. Evidence suggests that diets like the Mediterranean diet, which emphasize whole foods and healthy fats, can be effective in improving cognitive function.
Fructose's Impact on Brain Health
The consumption of high fructose levels has proven to lead to a decline in brain health, with potential long-term effects resembling those seen in Alzheimer's patients. Fructose can elevate the appetite and influence food choices, encouraging the consumption of more calorie-dense, unhealthy foods, thus promoting obesity and metabolic syndrome, both risk factors for Alzheimer's. The physiological effects of fructose, such as reduced ATP production and increased oxidative stress, contribute to cognitive dysfunction and enhance the risk of developing Alzheimer's. Tracking fructose intake and being mindful of hidden sugars in diets may play a significant role in maintaining brain health and preventing cognitive decline.
Alzheimer’s is now being called “type 3 diabetes” for its link to insulin resistance, type 2 diabetes, metabolic syndrome, and obesity.

Today, fructose is consumed mainly in highly concentrated forms such as fruit juice, dried fruit, and high fructose corn syrup in soda and ultra-processed foods. According to metabolic health and Alzheimer’s scientists, this abundance of fructose in our modern diet may be starving our brain's memory center due to a genetic survival trait.Rina sits down with Dr. Richard Johnson to discuss his revolutionary new hypothesis on the link between fructose consumption and Alzheimer’s disease. Rina and Dr. Johnson discuss the evolutionary mechanism behind fructose metabolism, insulin resistance, and weight gain that has completely backfired today due to its overconsumption. Dr. Richard Johnson is a professor of medicine at the University of Colorado Denver and has been a practicing physician and clinical scientist for over 25 years. He is internationally recognized for his seminal work on the role of fructose in obesity, diabetes, and now, Alzheimer’s disease.
