The so-called health gurus who advise consuming high-cholesterol foods and eliminating carbohydrates are misleading you. Peer-reviewed studies indicate that excessive cholesterol leads to atherosclerosis and, combined with uncontrolled cholesterol oxidation in the brain, is a significant factor in all dementia, including Alzheimer’s dementia. Recent studies have revealed that apolipoproteins found in the cholesterol-laden foods we eat can cross the blood-brain barrier and increase the risk of Alzheimer’s due to elevated amyloid beta deposition in the brain. This particular apolipoprotein variant is also linked to cardiovascular disease, atherogenicity, and high LDL cholesterol levels in the blood.
There is compelling evidence indicating that the relationship between elevated blood cholesterol levels and Alzheimer’s disease is associated with vascular and inflammatory alterations caused by oxidation rather than changes in brain cholesterol levels that are characteristic of Alzheimer’s disease. These oxidative plaques disrupt communication between brain cells and lead to the degeneration of neural pathways, ultimately resulting in cognitive decline and memory loss.
Furthermore, oxidized cholesterol has been found to trigger inflammation and oxidative stress in the brain, potentially exacerbating the advancement of neurodegenerative conditions such as Alzheimer’s disease. It is important to note that maintaining a healthy diet rich in antioxidants and nutrients, such as those found in the SOS-free lifestyle based on plant-based foods, reduces the oxidation of cholesterol and mitigates the risk of developing Alzheimer’s disease. Studies have shown that a plant-based diet benefits brain health and cognitive function, reducing the risk of all neurodegenerative diseases.
These studies provide insights into the link between oxidized cholesterol and Alzheimer’s disease, emphasizing the importance of addressing cholesterol oxidation in mitigating the risk of neurodegenerative disorders.
