Research shows plant-based diets reduce Alzheimer’s risk, contrasting with the harmful impact of Western diets rich in meats and processed foods. Rising U.S. obesity trends suggest a significant increase in Alzheimer’s rates by 2038.

In a detailed study, “Diet’s Role in Modifying Risk of Alzheimer’s Disease: History and Present Understanding” published in the Journal of Alzheimer’s Disease, we can finally see which diets are helpful in reducing the risk of developing Alzheimer’s disease. The role of diet in modifying the risk of Alzheimer’s disease is discussed in detail. Diets that are more plant-based, like the Mediterranean diet and traditional diets in China, Japan, and India, are shown to reduce risk, especially when compared to the Western diet.

Dietary Transitions and Alzheimer’s Risk

Alzheimer’s disease rates rise in these countries as they make the nutrition transition to the Western diet. This study identifies dementia risk factors including higher consumption of saturated fats, meat, especially red meat such as hamburgers and barbeque as well as processed meats such as hot dogs, and ultra-processed foods high in sugar and refined grains.

Understanding Food Impact on Alzheimer’s Risk

This review also lets us know why certain foods increase or reduce risk of Alzheimer’s disease. For example, meat raised risk of dementia the most by increasing risk factors such as inflammation, insulin resistance, oxidative stress, saturated fat, advanced glycation end products, and trimethylamine N-oxide. This study also outlines several foods that are protective against Alzheimer’s disease, such as green leafy vegetables, colorful fruits and vegetables, legumes (like beans), nuts, omega-3 fatty acids, and whole grains.

Ultra-Processed Foods and Health Risks

Ultra-processed foods can increase the risk of obesity and diabetes, themselves risk factors for Alzheimer’s disease. Ultra-processed foods often lack the very ingredients found in whole plant foods that keep dementia away, such as anti-inflammatory components and antioxidants.

Socioeconomic Factors in Diet Choices

Poverty is an important driver of Alzheimer’s disease in the U.S. since ultra-processed foods and meat are cheaper sources of energy than fruits, vegetables, whole grains, and other more nutritious foods, thus promoting obesity.

Projected Increase in Alzheimer’s Rates

The paper also suggests that Alzheimer’s disease rates in the US are projected to increase by 50% from 2018 levels by 2038. This calculation is based on comparing trends of obesity in the US with Alzheimer’s disease trends. This comparison shows a 20-year lag between obesity rates and Alzheimer’s disease rates. This estimate is very close to the estimate published by the Alzheimer’s Association in 2018, an estimate of a 56% increase. Our estimate suggests that the rising trend of obesity, due to consumption of meat and ultra-processed foods, is the force driving dementia. Although our personal risk of Alzheimer’s disease can be reduced with diet, it is expected that those who continue to eat the Western diet will continue to have a higher risk.

Expert Opinions on Diet and Alzheimer’s

“Grant and Blake comprehensively review and synthesize the role of dietary factors in Alzheimer’s disease. Evidence from diverse perspectives support that a diet that emphasizes fruits, vegetables, legumes, nuts, whole grains, and…de-emphasizes meat, especially red meat, saturated fats, and ultra-processed foods is associated with lower risk of Alzheimer’s disease. Physical inactivity and obesity also contribute to higher risk. In addition, the dietary and lifestyle patterns associated with higher risk of Alzheimer’s disease are known to affect the constellation of mechanisms believed to increase risk, including inflammation, insulin resistance and oxidative stress, among others. Grant and Blake make a strong case that, while further research is needed to better understand the mechanisms, diet and lifestyle factors linked to diabetes, cardiovascular disease, and some cancers are likely to influence risk of Alzheimer’s disease.”

“Grant and Blake provide a comprehensive review on the dietary and other factors that affect the risk of Alzheimer’s disease (AD). Apart from the particular type of diet they demonstrate that the consumption of red meat, insulin resistance, obesity, reactive oxygen species, and oxidative stress, phytochemicals and homocysteine amongst other factors interact with neuroinflammation and play a major role in the aetiology of AD. This treatise provides an excellent overview of modifiable risk factors for AD.”

    Hello to the freedom lovers of Iran, England has dominated the mullahs of Harum Laqmeh, most of the mullahs of Iran are Harum Laqmeh, but out of ten thousand mullahs, one is a bastard like Khamenei and is very mean, ignorant and criminal.Most of those who are in the government and system of the Islamic Republic are bastards.They are not, but maybe they are a parasite of the English countries, maybe that is why the four alphabets of the English word are parasitic, it has two, two, four books, God’s work, my mother’s aunt told me one month before Mehrdad’sdeath, we are English.He said: I am one month old.I am no longer alive, but before I die, I want to teach you 20 words that are both Persian and English, and these 20 words were written by the mother of Hayat Hoz’s brother in the car, computer, elephant, kangaroo in the notebook.Jackal, giraffe, jacket, police, cigarette, soup, spinach, sugar market, saffron, lemon, aunt.My mother Nasirin Amini Ghazizadeh died exactly one month later.Her husband died the next day.Why does God say that the Soviet Union is Russia, but they do not accept themselves?The word Russia is not a good word in Farsi.I have many words.When humans wanted to colonize the earth a hundred million years ago, the gods of the earth decided that the language of the earth would be Persian, because it is the most accurate word in the world and the names of most countries are connected to it.Mysteries, and the names placed on the map of the continent, country or sea.It is related to the people before us who gave us a message by shaping the continents and naming some countries.The name they put on Panama is correct, it means foot.The weight of the body is placed on the foot.There are two letters “foot” in the name of the country of Panama, but it is strange because the map of the country of Panama is exactly the foot of a bird, and the body of the bird is the map of the Central American country..The right wing of the bird is the map of the state of Alaska.And it is near the North Pole, the head of the bird is in the east of the American continent and the country of Canada and the north of Central America, if you follow the foot of the bird that is the map of the country of Panama., in the south, the foot of the bird will be visible.The old man has a map of the whole of South America, so you have to wonder who assigned these names, which is a map of a country like the country of Panama, but Panama isn’t a human foot, it’s a bird.Foot, the bird that flew in America and it is strange that in America all the flights take to the sky and Panama is the foot of the bird, follow him.We reach the view of that old man.In the map of continents and the names of countries and continents, there are many cases where the names of countries are somehow related to animals and birds in their shape or to the appearance of humans in the image of humans.taken and the word mazandaran means we are man and woman, there is a mazander in it and there are male and female embryos in it and I talked about this, anyone who has information about this please send me a short message.PhD in astronomy and world religions, Jahan Kathiri, Tehran n..r mobil dr kesiri 00989332197646 tehran iran

    While I can agree with the authors in general about the adulterated, toxic Western Diet, as a now senior lay victim/discoverer with a family history of very, very mild food allergies and dementia who first wrote the FDA (with replies, on file) on some of this eighteen years ago in October of 2005, not only do the authors fail to be comprehensive but they are too-typical of federal authorities and mainstream medicine professionals allergy, FDA approved food poisoning and excessive related/resultant medical error ignorant and incompetent. Furthermore, avoiding animal proteins for about twenty-eight years for allergy reasons in conjunction with failed medical testing resulted in a serious personal calcium deficiency (including temporary short-term memory deficits) by 2009 and by addressing that by supplementing with calcium carbonate which binds with phosphorus a very serious phosphorus deficiency by mid-March of 2021, which I’m still addressing on my own at-home in late 2023. And, there are other micronutrients in meats you just won’t find in plants.

  3. Eating meat causes dementia now? LMFAO

    As Elon would say “Go F Yourself”
    They are really really pushing the eat plants and bugs campaign hard.
