The amazing thing spinach does to your brain
Green leaves are healthy and not only for the diet or the heart.
A new study has found that there is a chance that it can also stop degenerative diseases like Alzheimer's.
So what are you waiting for?

Dr. Noa Bergman explains what causes Alzheimer's, is there a way to prevent the disease, and how to treat someone who has already become ill (Walla system!)
Leafy greens are perhaps one of the healthiest nutrients to add to your daily menu, partly because of the high presence of vitamin K which is known to be beneficial against heart disease and helps with blood clotting.
Now, an international team whose research was published in the scientific journal NATURE found a new and surprising benefit in the consumption of vitamin K - preventing cell death and stopping degenerative diseases such as Alzheimer's.
According to the Harvard School of Public Health, vitamin K comes in two forms.
The main type is phylloquinone, which is found in green leafy vegetables such as kale and spinach.
The second type is menkinones, found in some animal foods and fermented foods.
This type can also be produced by bacteria in the human body.
Researchers claim that there are 10 forms of vitamin K2 in the diet and each of them may be absorbed and act differently in the body.
Researchers from the Helmholtz Center in Munich, Tohoku University in Japan, the University of Ottawa in Canada and the Technical University of Dresden discovered that vitamin K acts as an antioxidant that inhibits cell death.
Researchers say that proptosis (Ferroptosis) "is a natural form of cell death related to iron in the cell and characterized by oxidative destruction of the cell membranes".
Very tasty and healthy.

Recently, proptosis has been implicated in Alzheimer's disease and other diseases.
The findings suggest that vitamin K therapy may be a powerful new strategy to ameliorate the diseases associated with proptosis.
As the prevention of proptosis is considered a very promising approach to the treatment of many neurodegenerative diseases, new mechanisms and compounds that modulate proptosis are being extensively investigated.
To identify these new molecules, a team of researchers led by Dr. Iken Mishima (Tohoku University) and Dr. Markus Konrad (Helmholtz Munich), systematically studied several natural vitamins, as well as their derivatives.
"To our surprise, we identified that vitamin K, including phylloquinone (vitamin K1) and menquinone-4 (vitamin K2), is able to effectively rescue cells and tissues from undergoing proptosis," explained Dr. Mishima.
This is not the first time, of course, that nutrition has been found to inhibit diseases such as Alzheimer's.
A study published in 2020 in the journal Neurology found, for example, that foods containing flavonols - compounds found in plant pigments - may delay and prevent Alzheimer's.
They wrote at the time that "Eating more fruits and vegetables and drinking more tea could be a relatively cheap and easy way for people to help prevent dementia."
The top sources of flavonols included pears, olive oil, kale, beans, tea, spinach, broccoli, wine, tomatoes and apples.
