We aimed to assess whether daily consumption of anthocyanin-rich cherry juice changed cognitive function in older adults with dementia. Blood pressure and anti-inflammatory effects were examined as secondary outcomes. Blood pressure and inflammatory markers CRP and IL-6 were measured at 6 and 12 weeks.
ANCOVA controlling for baseline and RMANOVA assessed change in cognition and blood pressure. Markers of inflammation CRP and IL-6 were not altered. Inclusion of an anthocyanin-rich beverage may be a practical and feasible way to improve total anthocyanin consumption in older adults with mild-to-moderate dementia, with potential to improve specific cognitive outcomes.

Memroy effects of purple sweet potato anthocyanin SPA and Ebhancement mushroom Ahthocyanins CME on lipid peroxidation, 1,1-diphenylpicrylhydrazyl DPPH radicals and cognitive deficits Holistic skincare solutions examined. Both Enjancement and CME exhibited Anthocyaninz radical scavenging activities with Effective natural remedies for hypertension potency. Furthermore, SPA markedly enhanced cognitive performance, assessed by passive avoidance test in ethanol-treated mice. Combined treatments with SPA and CME did not significantly influence the effects of SPA alone. These results demonstrate that anthocyanin prepared from purple sweet potato exhibits memory enhancing effects, which may be associated with its antioxidant properties.

It was hypothesized that daily anthocyanin intake would be similar to healthy older adults and that higher anthocyanin intake would be associated with better cognitive performance. Cognitive performance was assessed using a battery of tests including the Rey Auditory Verbal Learning Test RAVLT. Dietary intake was assessed through 3-day food records and anthocyanin intake was quantified using the PhenolExplorer food composition database. Overall, participants had low median intake of anthocyanins 5. On the RAVLT, the higher anthocyanin consumer group recalled a greater number of words after a short delay and a distracter task B, 2.
Anthocyanins and memory enhancement -
After 12 weeks, people who regularly consumed the cherry juice had significantly improved scores of tests related to memory and word-recall compared to those who were provided with an alternative fruit juice that contained minimal anthocyanins. As more is discovered about the health effects of anthocyanin-rich fruits, the demand for fruits with superior health benefits is growing.
An Australian-bred plum developed by Queensland government scientists, the Queen Garnet , has up to five times the levels of anthocyanins present than in normal plums. Animal studies show impressive results so far for its potential to improve health.
Obese rats fed with the Queen Garnet plum juice showed that their high blood pressure, fatty livers, poor heart function and arthritis returned to normal in just eight weeks. We are now investigating the role of the Queen Garnet plums on cognitive function in people with early signs of memory loss.
Food-based studies are complex. First, we need to understand how the body metabolises the bioactive compounds. Anthocyanins are quickly broken down in the digestive tract to a range of different digestive substances called metabolites , many of which are excreted in the urine within about six hours.
It may be the intact anthocyanin compound itself that exerts physiological effects. Or it could be one of its many metabolites. An acute cross-over study , for instance, found the blood pressure lowering effects of cherry juice over six hours were only seen if ml was consumed as a single serving, rather than as three ml servings over three hours.
Lastly, it is likely that anthocyanins in food may interact with other nutrients, and combinations of foods may show synergistic effects. In other words, they may have a greater combined effect than if consumed in isolation. Quitting smoking, cutting down on saturated fat and being physically active are also crucial for keeping ageing brains healthy.

All participants were aged 50 or more, with a clinical diagnosis of possible or probable mild cognitive impairment.
The primary aim of the trial was to determine whether a cognitive training intervention and anthocyanin supplements would prevent further cognitive decline or improve cognitive performance. The participants consumed different foods containing different amounts of anthocyanin.
And they were split into two groups according to their average daily anthocyanin intake. The participants consuming less than 10mg per day were categorized as lower intake consumers. And those consuming more than 10mg per day were categorized as higher intake consumers.
The cognitive performance of all participants was evaluated with tests like the Rey Auditory Verbal Learning Test. This is a widely used and well-validated cognitive test.
It consists of five consecutive trials in which participants recall a list of 15 words that have been read aloud to them. The results of the study indicate that higher intake anthocyanin consumers demonstrated better memory retention.
For example, they recalled between 2 and 3 words more than lower intake anthocyanin consumers after a short delay. Higher anthocyanin intakes were also associated with a slower rate of forgetting, with higher intake consumers forgetting around 2 words less on average after a long delay.
Therefore, the hypothesis that higher consumption of anthocyanins is associated with better cognitive performance is confirmed by the study. Thrivous develops Vitality Geroprotector to promote healthy cellular and metabolic function for better aging.
