For some years now, throughout the world and mainly in the United States, Alzheimer's disease has been a real health scourge. According to 2013 official statistics, this severe form of dementia affects about 5.2 million Americans, or 1 in 9 people over the age of 65. This disease is currently considered the 3rd leading cause of death in the United States, just behind heart disease and cancer.

Contrary to popular belief, poor nutrition is an important risk factor for degenerative diseases such as Alzheimer's through mechanisms similar to those that promote type 2 diabetes. The researchers discovered that if the pancreas secretes insulin, the brain also secretes insulin in a proportional way. For this reason, at the beginning of 2005, this pathology was provisionally named "type 3 diabetes". This process would be necessary for the survival of brain cells.

The opinion of an expert ...

According to experts, such as Dr. Ron Rosedale, brain disorders are largely caused by the constant burning of glucose to fuel your brain.
While insulin in the brain helps neurons take up glucose, insulin levels help regulate the release of other neurotransmitters such as acetylcholine. These substances are crucial for memory and learning. This is why a deficit of insulin in the brain alters these processes.
Research has also shown that people with type 2 diabetes lose more gray matter than normal. This type of atrophy obviously contributes to the development of dementia.

Memory tests and brain imaging have shown that low brain insulin levels are often concomitant with Alzheimer's disease. But also that a high cerebral glucose level is associated with a very bad memory. The structure of the hippocampus (the brain region where memory is stored) is abnormal. These data provide further evidence that glucose may contribute directly to the atrophy of this region of the brain.
Therefore, even if there is no pathology related to sugar, it is obvious that reducing glucose intake is still beneficial to brain function and mainly to cognition, especially in the elderly.

According to neurologist Dr. David Perlmutter, one of the most life-saving things you can do is to strictly limit your intake of sugar and non-vegetable carbohydrates.
If there's one thing you can do to prevent Alzheimer's disease, it's this. Some clinical research claims that a diet high in carbohydrates would increase the risk of developing dementia by up to 89%, while a diet high in good fatty acids would reduce that risk by 44%.
Clearly, this is just one factor among many. Knowing that we are made up of what we eat, the ideal is to avoid as much as possible additives, pesticides, contact with heavy metals, electromagnetic pollution, etc., all of which are known to be harmful.
It is now absolutely proven that when well nourished, the brain shows an amazing plasticity. Contrary to what the food and sugar industry would have us believe, controlling our food choices and lifestyle allows us to live a "healthy" old age and maintain our mental faculties until the end of our lives.
