- A study combines the green-Mediterranean eating pattern with slower brain age, measured by MRI scans.
- Those who ate the Mediterranean diet had three or four cups of green tea every day.
- Researchers suggest that green tea and other vegetable foods are most responsible for the advantages.
At the age of age, it’s not just about birthdays. It is also about how our organs get older inside. Scientists can now appreciate the “brain age” of a person from MRI scans and compare it with their actual age. If the brain age is older than expected, the risk of cognitive problems tends to be higher. If it is younger, that’s a good sign.
Nutrition is a way to support a healthier brain, and patterns in the Mediterranean style are always brain -friendly. Now a new analysis indicates a certain optimization that could possibly interfere with the brain age in the right direction. It drinks green tea as part of a higher polyphenol plan, plant-based.
In this study, the researchers followed the brain together with a group of blood proteins that can reflect inflammation and other brain -relevant biology. They found that people who were assigned to the green diet (a Mediterranean diet with additional polyphenols made of green tea and other sources) showed the cheapest protein shifts and overall signs of a “younger” brain profile.
How was this study carried out?
This was a secondary analysis of the 18-month direct and randomized controlled study, which was carried out in a large Israeli workplace. Around 300 adults (mainly men) with abdominal fat and/or dyslipidemia were randomized in three diet groups:
- Healthy nutrition guidelines
- A calorie -limited traditional Mediterranean diet
- A green-Mediterranean diet that emphasized more polyphenol
The green-Mediterranean group got 3 to 4 cups of green tea, walnuts and a Mankai (duckweed) every day. All groups received physical activity instructions. The brain’s MRI scans were used to estimate the brain with a validated deep learning model. The gap in brain (brain minus chronological age) was primary metricist. The researchers also measure more than 80 circulating proteins and searched for patterns that were bound over time with changes in brain.
What did the study find?
Two proteins-galectin-9 and decorin-stand: higher values were associated with an older than expected brain at the beginning of your studies. The Galectin 9 levels in the Green Med Group fell significantly over 18 months compared to the group for healthy guidelines. The overall pattern also shifted cheaper in the green-mediating group.
In explorative analyzes, drinking around four cups of green tea per day and the food of about seven walnut portions per week were associated with a greater reduction in Galectin-9. (The Mankai trends were similar in this data record, but not statistically significant.)
These molecular shifts correspond to previous direct plus reports that show that both Mediterranean and green-Mediterranean diets can reduce brain shrinkage over 18 months. Together, the results indicate that a Mediterranean pattern with a higher polyphenol-with green tea can contribute to the brain to slower.
As with all studies, there were restrictions. Most participants were male and had metabolic risk, so the results may not apply to everyone. The study also did not recognize any clear differences between the groups to standard cognitive tests over 18 months, so that the protein and MRI changes should be regarded as biological signals, not as evidence of clinical cognitive changes. There can also be other biomarkers of brain health that were not measured in this study. Longer attempts are required.
How does that apply to real life?
You don’t need a laboratory to react to it. The core droppings are practical: build a Mediterranean base and a layer in polyphenol-rich “green” upgrades with green tea as a slight daily upgrade.
- Make green tea your standard. Put on two to four cups a day (hot or driven). If you are sensitivity to caffeine, try an earlier limit or considered that Decaf Greenee consider.
- Go big on plants and polyphenols. Try to eat a small handful of walnuts for the most days. Fill your plate with vegetables, legumes, whole grains, herbs and leafy vegetables.
- Swap meat strategically. Tend from red/processed meat towards fish and poultry; This was part of the Middle-Earic nutritional plans that was inspired in this study and intensively for the Green Med approach.
- Don’t forget the basics. The study suggests that better glucose control and regular physical activity are also associated with the advantages of the brain. Therefore, put on solid meals from fiber -rich carbohydrates, protein and healthy fats and move on.
Our expert
In a randomized study, a green-Mediterranean eating pattern with green tea, walnuts, more plants and less red/processed meat was connected to younger-looking brains in the MRI and favorable changes in the blood proteins associated with the aging of the brain. It is not a magical ball, and further examinations are required to confirm long -term cognitive effects, but when everyday habits go, you can see green tea and food more Mediterranean Mediterranean meals such as intelligent movements for the health of the brain.
