有水稻几种维生素，包括维生素E，K和B长粒糙米中含有较多量的这些维生素比白米饭。

Rice contains vitamin B1, B2, B3, B6, B9, K and E.
White and Brown Rice
The best way to understand the distinction between white rice and糙米is to understand the distinction between whole grains and refined grains. Whole grains are mainly composed of 3 parts, according to Toby Smithson, a registered and licensed dietitian and national spokesperson for the Academy of Nutrition and Dietetics onShareCare。
麸皮是在种子上，以保护它的部分的硬外层。需要注意的是糠是不一样的壳。稻壳是晶粒的实际外壳，以及用于二者全谷物和细化晶粒被去除。然而，麸皮只是壳的下一层，并在粗粮不会被删除。这是一个丰富的矿物质，抗氧化剂和纤维的来源。
The germ is the core of the grain, and is often rich in many different nutrients, such as fat, protein, carbohydrates, antioxidants, and many other different beneficial compounds, including most of the vitamins in rice.
The endosperm is the largest part of the cereal grain by size. However, it consists almost entirely of starchy carbohydrates, with only a small quantity of protein. In fact, the high starch content of rice is often considered one of the大米的缺点。
糙米和白色r之间的主要区别ice is that brown rice is a whole grain that has been left intact. It has both the germ and the bran. It, therefore, has more nutritional content than white rice and contains plenty of antioxidants and fiber.
白米，on the other hand, has been stripped of the bran on the outside and the germ on the inside. It, therefore, has lost its most nutritious component. This is done is so that white rice can have a longer shelf life, better taste, and a nicer cooking quality. However, the trade-off is that cooked white rice nutrition consists almost entirely of starchy carbohydrates, including amylose and amylopectin. This contributes to the disadvantages of rices that have been refined.
不同类型的大米将有不同数量的这些淀粉，这将影响其消化率和质感的。赖斯是支链淀粉高的往往是粘性的，而大米是直链淀粉含量高，通常是没有的。
维生素B
根据哈佛P.H.陈中，有八个维生素B：B12（钴胺素），B9（叶酸），B 7（生物素），维生素B6（吡哆醇），B5（泛酸），B3（烟酸），B 2（核黄素）和B1（硫胺）。
根据the美国农业部食品成分数据库，1杯野生稻的含有0.626毫克的维生素B6（吡哆醇），1杯长粒的，富集的白米饭中含有维生素B6 0.147毫克和1杯长粒糙米含有0.882毫克的维生素B6的。
One cup of wild rice has 152 micrograms of B9 (folate), 1 cup of long-grain enriched white rice contains 153 micrograms of vitamin B9 and 1 cup of long-grain brown rice has 43 micrograms of vitamin B9.
One cup of wild rice has 0.184 milligrams of vitamin B1 (thiamin), 1 cup of long-grain enriched white rice contains 0.528 milligrams of vitamin B1 and 1 cup of long-grain brown rice contains 1.001 milligrams of vitamin B1.
野生稻的一个杯具有0.419毫克的维生素B2（核黄素），1杯长粒的富集白米具有维生素B2 0.021毫克和1杯长粒糙米具有0.176毫克的维生素B2的。
野生稻的一个杯包含10.773毫克的维生素B3（烟酸），1杯长粒的富集白米具有维生素B3 2.332毫克和长粒糙米具有12.014毫克的维生素B3。
而长粒糙米和长粒，富集的白米饭不含维生素A，1杯野生稻具有2微克维生素A.
维生素E
维生素E是白色，棕色和野生稻中发现。野生稻包含了三个最维生素E等，具有6倍以上的白色和糙米中的维生素E含量。这是根据发表在一个2015年3月的研究Journal of the Science of Food and Agricultureon the vitamin E content of different rice varieties.
根据美国农业部食物成分数据库，1杯野生稻的包含1.31毫克的维生素E，长粒的1杯富集白米含有维生素E 0.06毫克和1杯长粒的糙米含有1.11毫克的维生素E。
维生素E作为抗氧化剂，保护机体免受自由基引起的损伤。自由基是被链接到主机的疾病，包括癌症的不稳定分子。维生素E也是保护细胞膜和从破坏身体的各个脂溶性组织中有活性。
维生素K
根据INRTracker.com，维生素Kis very important in blood clotting and bone growth. This is because it is crucial in the transportation of calcium around the body. In fact, the ability of vitamin K to help blood clot has caused it to be utilized in treating warfarin overdoses. Warfarin is a blood-thinning medication.
根据the美国农业部食品成分数据库，维生素K的最高量的野生稻，其中包含的每杯维生素K 3微克中找到。长粒糙米中的一个杯具有的维生素K.不幸的是，长粒1.1微克，富集白米饭不包含任何维生素K.
