Guest guest Posted July 15, 2011 Report Share Posted July 15, 2011 Anyone know of any nutrition technology for the blind. I have a patient that would like to be able to read nutrition labels. She does have some software that will read word documents to her. Even if no technology ideas I would be curious about how other have helped the blind learn nutrition. So far I was able to have her hold food models of various sizes and that was helpful for her and we talked about using measuring spoons/cups but I would appreciate any other ideas.

Available online 12 June 2011. Abstract In the past, attempts have been made to estimate the carbohydrate contents of preagricultural human diets. Those estimations have primarily been based on interpretations of ethnographic data of modern hunter-gatherers. In this study, it was hypothesized that diets of modern hunter-gatherers vary in their carbohydrate content depending on ecoenvironments. Thus, using data of plant-to-animal subsistence ratios, we calculated the carbohydrate intake (percentage of the total energy) in 229 hunter-gatherer diets throughout the world and determined how differences in ecological environments altered carbohydrate intake. We found a wide range of carbohydrate intake ( & #8776;3%-50% of the total energy intake; median and mode, 16%-22% of the total energy). Hunter-gatherer diets were characterized by an identical carbohydrate intake (30%-35% of the total energy) over a wide range of latitude intervals (11°-40° north or south of the equator). However, with increasing latitude intervals from 41° to greater than 60°, carbohydrate intake decreased markedly from approximately equal to 20% to 9% or less of the total energy. Hunter-gatherers living in desert and tropical grasslands consumed the most carbohydrates ( & #8776;29%-34% of the total energy). Diets of hunter-gatherers living in northern areas (tundra and northern coniferous forest) contained a very low carbohydrate content ( & #8804;15% of the total energy). In conclusion, diets of hunter-gatherers showed substantial variation in their carbohydrate content. Independent of the local environment, however, the range of energy intake from carbohydrates in the diets of most hunter-gatherer societies was markedly different (lower) from the amounts currently recommended for healthy humans.

Guest guest Posted July 15, 2011 Report Share Posted July 15, 2011 , I'm not sure if others have chimed in yet, but you could contact your state department of education. They'll often have information available for teaching those with visual problems. There is quite a bit of technology available now, but I don't have information at my fingertips. I've asked a colleague of mine who has some experience and will let you know if I hear anything else.
