Diet rich in vitamin K to reduce risk of dementia and Alzheimer’s

Dementia is a disease that affects cognitive function. Symptoms can include memory loss and dysfunction, which can affect quality of life.
In a new rodent study, scientists looked at how vitamin K may affect the cognitive abilities of aged rats. Researchers have found that the vitamin has the potential to improve cognitive abilities and protect against the risk of dementia.

The risk of developing dementia increases with age. Dementia is the collective term for a group of diseases, of which Alzheimer’s disease is the most common, affecting millions of people. There is currently no cure for dementia, but some medications can relieve symptoms. Additionally, researchers continue to look for ways to reduce the severity of symptoms or prevent the disease from progressing so rapidly.

A new study suggests vitamin K may help protect against “cognitive deterioration.” The new study, presented at the Experimental Biology Meeting on April 5, 2022, tested the administration of a vitamin K supplement to rats.

Dementia at a glance

Dementia “is a general term for loss of memory, speech, problem solving, and other thinking skills severe enough to interfere with daily living. »
Alzheimer’s disease is thought to be the result of the accumulation of abnormal proteins in the brain called amyloid plaques. These can prevent brain cells from sending signals, as well as before and damage them. There are other types of dementia, and vascular dementia is thought to be caused by decreased blood flow to the brain, which can also damage brain cells.
According to the latest data, people over the age of 65 have the highest risk of developing Alzheimer’s dementia.

Listed signs and symptoms of dementia include the following:

– Forgetting the names of loved ones
– Mood swings
– Inability to recall old memories
– Difficulty completing tasks
– have communication difficulties

Vitamin K in a nutshell

It is important to consume many types of vitamins and minerals to stay healthy. One vitamin that plays a role in brain and bone health is vitamin K, which is commonly found in leafy green vegetables. The aging process is associated with the deterioration of brain function. Vitamin K is a fat-soluble natural vitamin that protects the brain from developing Alzheimer’s disease.
There is a recommended daily allowance for vitamin K that varies by age. Eating adequate amounts of vegetables and fruits is good for maintaining normal vitamin K levels. However, dietary supplements are also available to replace natural sources if you cannot consume them.

Study on vitamin K and dementia

Because vitamin K can affect brain function, in this study the researchers wanted to see how it affects cognitive function in rats. The researchers conducted a 17-month trial on rats. One group received a vitamin K supplement, the other did not. The researchers administered menaquinone-7 (MK-7), which the authors say is “an important form of vitamin K2.” The rats underwent a battery of cognitive function tests throughout the study. According to the authors, they were tested “to assess cognitive level, anxiety, and depressive behavior. »
At the end of the study, the rats given the vitamin K supplements showed less cognitive impairment, depression and anxiety. In addition, the authors note that these rats exhibited “improved spatial memory and learning ability.” »

“Vitamin K2 showed very promising effects in inhibiting age-related behavioral, functional, biochemical, and histopathological changes in the aging senile brain,” the study authors note. They also conclude that “the most important implications are the attention to vitamin K in the elderly population and its relationship to Alzheimer’s disease and other age-related neurodegenerative diseases. »

Vitamin K may support brain health.

There are many forms of vitamin K, and they all have different dietary sources. MK-7 is found in fermented vegetables and the benefits of consuming these foods are well known. They’re great for your gut microbiome, which has a known connection to cognitive decline.
