Authors: Yuri Nomi, Keiko Iwasaki-Kurashige, Hitoshi Matsumoto
This study investigated the therapeutic effects of anthocyanins on vision and eye health. Anthocyanins are natural pigments found in various fruits and vegetables and are known for their antioxidant properties. The researchers examined various clinical studies that investigated the relationship between the intake of anthocyanins and various aspects of vision and eye health. Various parameters such as the improvement of visual acuity, the reduction of eye inflammation and the reduction of the risk of age-related eye diseases were taken into account. The results showed that taking anthocyanins had positive effects on vision and eye health. An improvement in visual acuity was observed in people with age-related macular degeneration. In addition, there were positive effects on the reduction of oxidative stress and inflammation in the eye. The study suggests that anthocyanins may have potential therapeutic effects on vision and eye health. They can help to improve visual acuity and reduce the risk of age-related eye diseases.

Authors: Akihiro Yagi, Kiyoshi Fujimoto, Kazumi Michihiro, Bevy Goh, Daniel Tsi, Hajime Nagai
This study investigated the effect of lutein supplementation on visual fatigue. Lutein is a carotenoid that is present in high concentrations in the macula, the area of the eye with high visual acuity, and is known for its protective properties. Test subjects were recruited for the study who suffered from visual fatigue due to long periods of screen work. One group received a lutein as a dietary supplement for a certain period of time, while the other group received a placebo . The results showed that the group supplementing lutein experienced a significant reduction in visual fatigue. The subjects reported improved visual acuity, a reduced feeling of eye strain and faster recovery after visual effort compared to the placebo group. In addition, objective measurements were also carried out to record changes in eye physiology. It was found that the group taking lutein showed better maintenance of eye function and less strain on the eye muscles. These results suggest that lutein supplementation may be an effective way to reduce visual fatigue, especially in people who perform prolonged VDT work. Lutein’s protective effect on the eyes and its ability to improve visual performance make it a promising nutrient for eye health.

The present study investigated the effects of blackcurrant anthocyanoside intake on dark adaptation and transient refractive change due to VDU work in healthy individuals. Anthocyanosides are bioactive compounds found in blackcurrants and have a strong antioxidant effect. The study was conducted with a group of healthy volunteers. Some of the test subjects received anthocyanosides from blackcurrants as a dietary supplement over a certain period of time, while the other group received a placebo. The results showed that the group that took anthocyanosides from blackcurrants had improved dark adaptation. This means that they were able to adapt more quickly to darkness and had better vision in poorly lit environments. In addition, it was found that those who took anthocyanosides showed less temporary refractive change from screen time. This means that their vision was less impaired when they looked at a screen for long periods of time. These results suggest that the intake of anthocyanosides from blackcurrants may have beneficial effects on dark adaptation and transient refractive change due to VDU work. This suggests that black Currants and products such as CurrantCraft® with their high anthocyanoside content could have potential benefits for eye health.

The study investigated the effects of timed consumption of New Zealand blackcurrant juice on positive emotional responses during self-motivated moderate walking exercise in healthy, sedentary adults. Participants in the study were inactive and were asked to perform moderate walking exercise. Before training, they were given either blackcurrant juice or a placebo drink. The blackcurrant juice contains natural compounds known as anthocyanins, which have antioxidant properties. The results showed that those who consumed the blackcurrant juice had a significantly higher positive emotional response during exercise than those who consumed the placebo.drink. This positive mood included feelings such as joy, activation and energy.

The presented study sheds light on the effects of blackcurrant anthocyanin supplementation on cyclic glycine proline (CGP) levels in the cerebrospinal fluid of Parkinson’s patients. The aim is to determine whether this supplementation can contribute to improving the function of insulin-like growth factor-1 (IGF-1). The researchers conducted a randomized, placebo-controlled study with Parkinson’s patients. One group received daily anthocyanin supplements from blackcurrants over a period of 12 weeks, while the other group received a placebo. Before and after the intervention, the participants’ cerebrospinal fluid was analyzed to determine the CGP level. The results showed that the supplementation of blackcurrant anthocyanins led to a significant increase in the CGP level in the cerebrospinal fluid. This increase in CGP could improve the function of IGF-1. IGF-1 plays an important role in neuroprotective effects in the brain and also has effects on metabolism and insulin sensitivity. The study suggests that blackcurrant anthocyanin supplementation could potentially serve as a treatment option to improve IGF-1 function in Parkinson’s patients.
Effects of blackcurrant juice on attention, mood and spectral activity of brain waves in young healthy volunteers
Authors: Watson AW, Okello EJ, Brooker HJ, Lester S, McDougall GJ, Wesnes KA
Here, the effects of blackcurrant juice on attention, mood and the spectral activity pattern of brain waves in young healthy volunteers are investigated. The researchers conducted a randomized, placebo-controlled study with a group of young volunteers. One part of the group received blackcurrant juice, while the other part received a placebo. Before and after the intervention, various tests were carried out to measure attention and mood. In addition, the participants’ brain activity was recorded using electroencephalographic (EEG) measurements. The results showed that the group that consumed blackcurrant juice had improved attention and mood compared to the placebo group. The EEG measurements also showed a change in the spectral activity pattern of brain waves, particularly an increase in activity in the alpha range, which is associated with relaxation and increased cognitive performance. The study suggests that blackcurrant juice may have positive effects on attention, mood and brain activity in young healthy people. However, the exact mechanisms underlying these effects are not yet fully understood and require further investigation.

Authors: Nilsson A, Salo I, Plaza M, Björck I.
The subject of the studies was the effects of a mixed berry drink on cognitive functions and cardiometabolic risk markers in healthy older adults. This was a randomized cross-over study. In the study, healthy older adults took part in two treatment phases in which they received either the mixed berry drink or a placebo. The treatment phases were carried out with a wash phase in between. Cognitive function tests were performed before and after each treatment phase to assess cognitive performance. In addition, various cardiometabolic risk markers, such as blood pressure, blood lipids and blood glucose, were measured. The results showed that consumption of the mixed berry drink led to an improvement in cognitive functions. In particular, the participants’ attention and working memory improved significantly compared to the placebo. In addition, positive changes were observed in some cardiometabolic risk markers, such as a reduction in systolic blood pressure and an improvement in blood lipid levels. The study suggests that regular consumption of a mixed berry drink may have beneficial effects on cognitive function and cardiometabolic health in healthy older adults. The exact mechanisms underlying these effects are not yet fully understood and require further investigation. further investigations.

This study analyzes the effects of acute supplementation with black currant extracts on cognitive function and monoamine oxidase-B (MAO-B) inhibition in healthy young adults. In the study, participants received a single dose of blackcurrant extract or a placebo. Cognitive function tests were performed before and after supplementation to assess the effects on cognitive performance. In addition, biomarkers for MAO-B activity were measured in urine. The results show that acute supplementation with blackcurrant extracts led to improvements in various cognitive functions, including working memory and attention. In addition, a significant inhibition of MAO-B activity was observed. These results suggest that acute supplementation with blackcurrant extracts may have positive effects on cognitive function while inhibiting MAO-B activity. MAO-B is an enzyme responsible for the degradation of neurotransmitters such as dopamine and serotonin.
The study suggests that blackcurrant extracts have the potential to improve cognitive function, possibly by inhibiting MAO-B. However, further research is needed to understand the long-term effects and the exact mechanism of these effects.
