while it may turn your skin yellow/orange vitamin a from fruits and vegetables is not toxic. but you do need to worry about missing out on other key nutrients. if all you are eating are yams and romaine lettuce you may not be getting enough fat protein and are at risk for other vitamin/mineral inadequacies like vitamin d. i suggest seeing a registered dietitian to develop a balanced eating plan to help you be healthy and lose weight if needed. good luck!
am i getting too much vitamin a? . for the last couple of months i have been on a unusual diet of mostly ceasar salad and yams. now i eat around a full heart of romaine lettuce a day and a large yam a day. the diet works great but i didn't look at the vitamin count. i recently noticed that i have been consuming a large amount of vitamin a. i don't take any supplements but i am now worried that i might have vitamin a toxicity. i looked up some of the symptoms and i don't think i have any but should i stop this diet?
