Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Berries, particularly those rich in anthocyanins such as blueberries, blackcurrants, and bilberries, have been studied for their potential benefits to the senses, especially vision. Scientific research suggests that the high concentration of antioxidant compounds found in these berries may help protect eye tissues from oxidative stress and age-related decline. For example, bilberry (a type of berry) has a long history of use in traditional medicine for supporting night vision, but more recent clinical studies have investigated its effects on visual acuity and retinal health. Some randomized controlled trials have shown modest improvements in visual function, particularly under low-light conditions, although results are not always consistent.

Additionally, the general antioxidant and anti-inflammatory properties of berry polyphenols are believed to support overall sensory organ health, including hearing and taste, though evidence for these effects is much more limited than for vision. A 2018 review in Nutrients highlighted the potential of berry anthocyanins to slow the progression of age-related macular degeneration, though it noted that more rigorous long-term studies are necessary to confirm these benefits. Overall, while there is scientific interest and some supportive evidence for berries benefiting the senses, especially sight, the strength and consistency of this evidence are moderate, not definitive.
