Alzheimer’s: a new study reveals the benefits of green tea consumption in preventing dementia

Other factors that influence the protective cerebral effect of green tea are its high content of antioxidants, caffeine and L-theanine.

By now we all know that green tea is considered the healthiest drink on the planet. It is composed of many antioxidants and nutrients with great effects on the body. Not surprisingly, there are various scientific references that endorse its properties to improve brain function, reduces the risk of cancer, enhances digestive and intestinal health, strengthens the immune system and is a great ally to burn fat. Among many other impressive benefits, recently a study published in the Journal of Science and Technology published new findings led by Chinese scientists who found that Drinking green tea can help prevent Alzheimer’s disease.

As an aside, it is important to mention that in recent months the cases of Alzheimer’s and dementia have had a worrying increase: about 5.7 million people in the United States currently live with Alzheimer’s, considered the most common form of dementia. Although it is one of the diseases that has most plagued scientists and researchers around the world and has been classified as a scientific enigma, more and more people are interested in reducing the risk. Not in vain every day there are more references on the best dietary recommendations to protect brain health, in fact recently, experts from the Mayo Clinic endorsed the specific benefits of two eating styles: the DASH diet (Dietary Approaches to Stop Hypertension) and the Mediterranean diet, recognized for its benefits for heart health.

In such a way that our daily habits, lifestyle and type of diet, directly influence brain deterioration. Taking into account the state of health of the world population that is aging less gracefully every day, due to the high rate of chronic diseases, a poor diet and little physical activity. It is not surprising to say that neurodegenerative diseases, including Alzheimer’s disease, are showing increasingly high and rapid incidence rates.

The study was led by scientists from Anhui University and China University of Science and Technology and the most relevant finding was that regular green tea intake can help reduce synaptic damage, thereby having the ability to improve learning and memory. The research provides a theoretical basis to explain the mechanism of prevention of Alzheimer’s disease through the consumption of tea and its subsequent application.

Alzheimer’s disease is a progressive neurodegenerative condition characterized by decreased memory and thinking, as well as behavioral problems. While the precise causes of Alzheimer’s disease remain unclear, it is believed that beta-amyloid plays a key role and what happens is that this protein can clump together, forming plaques that disrupt communication between nerve cells. It is currently estimated that almost 50 million people worldwide are living with this disease and by 2050, this number is expected to increase to 131.5 million. Impressive!

There are other quite relevant references around the consumption of green tea and its benefits in prevention. Recent studies show positive results on how EGCG could help prevent the formation of beta-amyloid plaque, bringing scientists closer to much-needed prevention strategies for Alzheimer’s disease. Various researchers point out that one of the greatest benefits of green tea is that epigallocatechin polyphenol gallate (EGCG) stops beta-amyloid plaque formation, a hallmark of Alzheimer’s disease.

This other study was published in the Journal of Neuroscience, in which researchers studied the effects of treating genetically altered mice to develop Alzheimer’s disease with high doses of the antioxidant green tea. After several months of daily EGCG injections, the results showed that nerve cells in treated mice generated up to 54% less beta-amyloid protein than nerve cells from untreated mice. So the findings suggest that the concentrated components of green tea and its powerful antioxidants, they can decrease the formation of beta-amyloid plaque in the brain. Therefore, it has been proven that the inclusion of EGCG in the daily diet can be an effective measure to prevent and treat the disease.

Although the consumption of green tea works as a great ally to reduce the risk of dementia and Alzheimer’s, it is important include abundant natural foods in the diet that are conspicuous for their antioxidant content. To obtain the required daily dose, it is important to consume them on a daily basis, therefore it is important to supplement with the consumption of: blueberries, berries, tomatoes, broccoli, artichokes, garlic, cinnamon, dark chocolate, beans, apples, eggs and vegetables. green leaf.

Green tea is related to benefits to improve intelligence and keep us much more agile mentally. One of the main reasons is its caffeine content, which is considered its active ingredient and gives it a great stimulating power. Best of all, it is an option that does not contain as much caffeine as coffee, therefore it can be consumed in greater quantities and provides enough caffeine to produce a response without causing the nervous effect associated with too much caffeine. What caffeine produces in the brain is blocking an inhibitory neurotransmitter called adenosine. In this way, it increases the activation of neurons and the concentration of neurotransmitters such as dopamine and norepinephrine.

In fact, there are several scientific references in which the benefits of caffeine consumption to improve brain function have been proven, including the improvements in mood, mood, reaction time, and memory. However, green tea contains more components that benefit the brain than caffeine. Its content in an amino acid called L-theanine is striking, which can cross the blood-brain barrier. This substance increases the activity of the inhibitory neurotransmitter GABA (gamma-aminobutyric acid), which has antioxidant effects. It also increases dopamine and wave production in the brain. Studies have shown that caffeine and L-theanine can have synergistic effects. The combination of the two is quite powerful in improving brain function.

Last but not least, green tea has been shown to provide much more stable energy, making it safe to consume throughout the day. It also increases productivity and mood, and is related to a long list of health benefits: improves digestive and intestinal health, boosts the immune system, purifies the liver, has great soothing properties and is a great ally for weight loss.
