Blueberries improve memory and prevent dementia – healing practice

Why eating blueberries is so healthy

the recording of blueberries in the daily diet can have positive effects on the heart and intestinal flora as well Improve memory and brain function and also reduce unhealthy LDL cholesterol. So blueberries show a remarkable neuroprotective potential.

In a new study involving experts from University of East Anglia examined how the consumption of blueberries in the cognitive and neural functions It affects older adults. The results can be found in the journal Frontiers in Nutrition.

How Blueberries Affect Neurodegeneration

The team wanted to find out what effect blueberries had on the age-related neurodegeneration have. To do this, the effects of blueberry consumption over a twelve-week period on the brain function and cholesterol levels studied in 60 people.

The participants had a Age between 50 and 80 years and had no cognitive disorders.

Half of the participants went every day. freeze dried cranberry powder managed for consumption. The amount corresponded to a cup or 100 grams of fresh blueberries. The remaining participants only received a placebo as a control.

Effects of flavonoids on cognition

According to the study author dr david vauzour It had already been shown in previous studies that a higher intake of flavonoids (a type of polyphenol) in food is associated with slower cognitive decline and dementia.

Furthermore, these studies showed that foods, which many Anthocyanins and proanthocyanidins contain that improve cognitive skills. Berries, for example, contain anthocyanins and proanthocyanidins, which give them their red, blue, or violet color, depending on the doctor.

Also, blueberries are for her. antioxidant and anti-inflammatory properties known and the berries contain large amounts of the micronutrients mentioned above.

Better memory thanks to blueberries

The new study has now shown that daily consumption of blueberries actually improves participants’ memory of everyday events (visual episodic memory) clearly improved.

This also applies to them. neural functions and the blood supply to the brainthe call brain perfusionthe researchers add.

Blueberries protect cognition

We found that participants who consumed the cranberry powder showed significantly improved episodic memory performance, combined with better circulation of essential nutrients like oxygen and glucose to key parts of the brain that support cognition, particularly memory consolidation and retrieval. the memory.“, reports dr Vauzour in a press release.

Blueberries also protect blood vessels

Furthermore, in the group of participants who ate blueberries, a significant decrease in LDL cholesterol levels. LDL cholesterol level is considered a risk factor for atherosclerosis (hardening of the arteries) known.

According to experts, the effects of blueberries on LDL cholesterol levels suggest that consumption of blueberries also Improve the health of blood vessels maybe Improved cerebral circulation and cognitive abilities could contribute.

Additionally, independent research recently found that a daily intake of blueberry powder cardiovascular functions improved significantly. The powder only had to be taken for a period of one month.

This seems to confirm the researchers’ thesis and suggests that blueberries also protect against the development of cardiovascular diseases I might.

Protection against tooth decay and inflammation.

However, the beneficial effects of blueberries go much further. Another study showed that decay berries protect and reduce inflammation.

Blueberries improve intestinal flora

According to another study, blueberries also help colonize healthy bacteria in the digestive system. These changes in the intestinal flora can, in turn, provide multiple health benefits.

Cognitive benefits proven for the first time

Demonstrating in humans that blueberry intake can improve cognitive performance and identifying some of the mechanisms responsible for this is an important step for this area of ​​research“, summarizes dr Vauzour.

It is also very encouraging that a relatively short shot of blueberries resulted in significant improvements in memory and neural function in a period of just 12 weeks. (What)
