A study conducted by Boston University suggests that weight loss in patient's suffering from Alzheimer's disease is due, in part, to the lack of color contrast between dinnerware and food
Almost 40% of Alzheimer's patients experience significant weight loss. A study out of Boston University suggests that the weight loss is due in part to the loss of the ability to distinguish contrast between colors.
People with Alzheimer's are not able to distinguish light colored food and drink on or in typically light colored tableware. When using tableware that offered a high contrast to the food and drink (i.e.: bright red and bright blue), researchers noticed that the participants in the study increased their food intake by 24% and liquid intake by 84% (1).
- 40% of Alzheimer's patients experience significant weight loss
- More than 60% of people with Alzheimer's Disease have a decrease in visual capacity(2)
- Up to 50% of the fluctuations in the ability of someone with Alzheimer's Disease to perform activities of daily living can be attributed to deficits in visual capacity (2)
- Research indicates that people with Alzheimer's Disease experienced a 24% increase in food intake and 84% increase in liquid intake when eating and drinking with tableware that offers a high contrast color (1)
- The human eye has more receptors in the retina to see red than to see any other color
- Alzheimer's patients show greater deficits in their ability to see colors in the blue-violet range
