the authors noted "a lack of human data and contradictory findings hampered conclusions". Another study has found that drinking vegetable juice reduces risks of Alzheimer's disease by 76%. However, the British Nutrition Foundation holds that although vegetable juice counts as a serving, it can only count as one serving, regardless of the amount of juice drunk. Additionally, A 2007 Japanese study showed that although Japanese commercial juices had nutritional benefits, they were insufficient as a primary mode of vegetable consumption. Many popular vegetable juices, particularly ones with high tomato content, are high in sodium, and therefore consumption of them for health must be carefully considered. Some vegetables such as beets also contain large amounts of sugar, so care must be taken when adding these to juices. Consumption of certain vegetable juices can also contribute substantially to oxalate intake; people who form calcium oxalate stones may be advised to limit consumption of vegetable juices. Cases of oxalate nephropathy associated with oxalate-rich juice intake have also been documented in susceptible individuals. Although the actual nutritional benefits of vegetable juice are contested, a 2008 UC Davis study found that drinking vegetable juice daily significantly increased drinkers' chances of meeting the daily recommended number of vegetable servings. Having an easy source of vegetables encouraged drinkers to incorporate more vegetables into their diets. Children who refuse whole vegetables may find vegetable juice, when blended with fruit juice, a palatable alternative. See also Juicing List of juices Raw veganism References External links Raw foods
