Health benefits
A. Health benefits according to studies
1. Diabetes
In the investigation of brown rice and white rice and theirs effect in diabetes found that Substitution of whole grains, including brown rice, for white rice may lower risk of type 2 diabetes. These data support the recommendation that most carbohydrate intake should come from whole grains rather than refined grains to help prevent type 2 diabetes, according to "White rice, brown rice, and risk of type 2 diabetes in US men and women" by Sun Q, Spiegelman D, van Dam RM, Holmes MD, Malik VS, Willett WC, Hu FB.(a)

2. Human serum albumin
Human serum albumin (HSA) and how to prevent the risk of risk of viral transmission from donors found that a rice seed bioreactor produces cost-effective recombinant HSA that is safe and can help to satisfy an increasing worldwide demand for human serum albumin, according to "Large-scale production of functional human serum albumin from transgenic rice seeds" by He Y, Ning T, Xie T, Qiu Q, Zhang L, Sun Y, Jiang D, Fu K, Yin F, Zhang W, Shen L, Wang H, Li J, Lin Q, Sun Y, Li H, Zhu Y, Yang D.(b)

3. Prebiotic
In the assessment of the prebiotic effects of brown rice fermented by Aspergillus oryzae (FBRA) on the intestinal environment in vitro and in healthy adults found that FBRA has the potentials as a prebiotic, however, we could not detect its effects on the intestinal environment in vivo. The results in a clinical study indicated that FBRA could be safely used for healthy adults, according to "Effects of fermented brown rice on the intestinal environments in healthy adult" by Nemoto H, Ikata K, Arimochi H, Iwasaki T, Ohnishi Y, Kuwahara T, Kataoka K.(c)

4. Lower weight gain and hepatic lipid
In the classification of the hydrolysates of white rice protein (WRP), brown rice protein (BRP), and soy protein (SP) and its physiological effects found that animals fed the brown rice protein hydrolysate (BRPH)supplemented diet also had lower final body weight, liver weight, very low density lipoprotein cholesterol (VLDL-C), and liver cholesterol, and higher fecal fat and bile acid excretion than the control, according to "Lower weight gain and hepatic lipid content in hamsters fed high fat diets supplemented with white rice protein, brown rice protein, soy protein, and their hydrolysates" by Zhang H, Bartley GE, Mitchell CR, Zhang H, Yokoyama W.(d)

5. Hypercholesterolemia
In the experiment of white rice (WR), brown rice (BR), and germinated brown rice (GBR) and theirs effect in the progress of atherosclerosis found that rabbits fed a GBR diet demonstrated significantly lower levels of total cholesterol (TC), low-density lipoprotein (LDL), LDL/HDL, and atherogenic index (AI) and a higher level of high-density lipoprotein (HDL). Results from atherosclerotic plaque assessment, according to "Improving the lipid profile in hypercholesterolemia-induced rabbit by supplementation of germinated brown rice" by Mohd Esa N, Abdul Kadir KK, Amom Z, Azlan A.(e)

6. Etc.

B. Health benefits according to concentration
1. Manganese
It is one of important trace in preventing osteoporosis, according to the study of "[Study of estrogen deficiency impact on manganese levels in teeth and mandible of rats after ovariectomy].

[Article in Spanish]" by Rodríguez-Rodríguez E, Bermejo LM, López-Sobaler AM, Ortega RM.(I)

2. Selenium
Oat contains trace minerals selenium which is essential for the healthy function of the thyroid and immune system as it increases the antioxidant defense system by fighting against the forming of free radicals and reduce the risk of irregular cells growth causes of tumor and cancer, according to the study of "Selenium in the immune system" by Arthur JR, McKenzie RC, Beckett GJ., posted in PubMed (http://www.ncbi.nlm.nih.gov/pubmed/12730442)

3. Magnessium
Magnesium not only important for bone health, according to the study of "Magnesium, zinc, copper, manganese, and selenium levels in postmenopausal women with osteoporosis. Can magnesium play a key role in osteoporosis?" by Odabasi E, Turan M, Aydin A, Akay C, Kutlu M(II) but also play and important role in protecting against Alzheimer's disease, according to the study of "Altered ionized magnesium levels in mild-to-moderate Alzheimer's disease" by Barbagallo M, Belvedere M, Di Bella G, Dominguez LJ.(II)

4. Tryptophan
Tryptophan is one of the 10 essential amino acids which the body uses to synthesize the proteins for brain cells need, thus enhancing the nerve cells in information transmitting between themselves and cells in the parts of the body that reduces the risk of anxiety and depression, according to the study of "The effects of tryptophan depletion on neural responses to emotional words in remitted depression" by Roiser JP, Levy J, Fromm SJ, Nugent AC, Talagala SL, Hasler G, Henn FA, Sahakian BJ, Drevets WC.(III)

5. Etc.

C. Other health benefits
1. Diabetes
Since it is a complex carbohydrate and contained high amount of fiber, it helps to release the glucose into blood stream slowly, thus decreasing the risk of insulin sensitive and type 2 diabetes, according to the study of "Efficacy of high-fiber diets in the management of type 2 diabetes mellitus" by Wolfram T, Ismail-Beigi F., posted in PubMed(1)

2. Antioxidants
Beside containing high levels of magnesium which is necessary for the synthesis of fatty acids to produce energy for our body needs, it also is one of the important component of antioxidant enzyme of which increases the body in fighting against the forming of free radical, according to the study of "Analysis of antioxidant enzyme activity and magnesium level in chronic obstructive pulmonary disease (COPD)" by Kurys E, Kurys P, Kuźniar A, Kieszko R., posted in PubMed(2)

It also contains a variety of important nutrients, including calcium for the hair, teeth, nails, muscles and bones, according to the article of "Minerals" posted in VeganPeace(3)
