Health benefits
A. health benefits according to studies
1.
Lutein + zeaxanthin
In the investigation of carotenoid database for fruits, vegetables, and selected multicomponent foods, including mustard green found that contributors of lutein + zeaxanthin included collard, mustard, or turnip greens; spinach; and broccoli, according to "The development and application of a carotenoid database for fruits, vegetables, and selected multicomponent foods" by Chug-Ahuja JK, Holden JM, Forman MR, Mangels AR, Beecher GR, Lanza E.(a)

2.
Phenolic components
In the observation of the phenolic components of 17 leafy vegetables from Brassica species other than Brassica oleracea, including mustard green identified 71 phenolic compounds consisting of kaempferol 3-O-diglucoside-7-O-glucoside derivatives, isorhamnetin 3-O-glucoside-7-O-glucoside hydroxycinnamoyl gentiobioses, hydroxycinnamoylmalic acids, and hydroxycinnamoylquinic acids. Ten of the compounds, 3-O-diacyltriglucoside-7-O-glucosides of kaempferol and quercetin, had not been previously reported, according to "Phenolic component profiles of mustard greens, yu choy, and 15 other brassica vegetables" by Lin LZ, Harnly JM.(b)

3. Prostate cancer
In the evaluation of Brassica vegetables, including broccoli, cabbage, mustard and collard greens, and bok choy and their anti prostate cancer effects found that three reported statistically significant reduced risks (P < 0.05) and one reported a borderline significant reduced risk (P = 0.06) with high Brassica vegetable consumption. The epidemiological literature provides modest support for the hypothesis that high intakes of Brassica vegetables reduce prostate cancer risk, according to "Brassica vegetables and prostate cancer risk: a review of the epidemiological evidence" by Kristal AR, Lampe JW.(c)

4. Chronic diseases
In the examination of
Collard greens, mustard greens, kale, okra, green onion, butter beans, butter peas, purple hull peas, rutabagas, and eggplant are frequently consumed by African Americans in the southeast United States and theirs effect in chronic diseases found that these indigenous vegetables consumed by African Americans in the southeastern United States are good sources of the phenolic compounds, which might provide anti-oxidative protection against free radicals in the human body. Consumption of these vegetables might reduce the risk of chronic diseases, according to "Total phenolics and antioxidant capacity of indigenous vegetables in the southeast United States: Alabama Collaboration for Cardiovascular Equality Project" by Huang Z, Wang B, Eaves DH, Shikany JM, Pace RD.(d)

B. Health benefits according to concentration
1. Vitamin K
Vitamin K not only plays an important role in protecting our skin from aging, it is also needed for the proper clotting of blood, thus decreasing the risk of excessive bleeding, in a study of "Delayed vitamin K deficiency as a cause of bleeding: still a concern in the 21st century!" by Kasatkar P, Shetty S, Ghosh K., posted in PubMed, researchers found that Laboratory tests confirmed acquired bleeding diathesis due to vitamin K deficiency, which was corrected after adequate vitamin K supplementation. VKDB is not an uncommon phenomenon and should be considered in the differential diagnosis of a child with bleeding diathesis.

2. Vitamin A
Vitamin A is not only important in preventing types I diabetes, according to "A close relationship between type 1 diabetes and vitamin A-deficiency and matrix metalloproteinase and hyaluronidase activities in skin tissues" by Takahashi N, Takasu S.(1) but also may be associated with compromised bone health, according to "Vitamins and bone health: beyond calcium and vitamin D" by Ahmadieh H, Arabi A.(2)

3. Vitamin C
In the evaluation of pulmonary dysfunction. and it effects on pulmonary dysfunction found that At present, evidence from randomised-controlled trials is insufficient to recommend a specific role for vitamin C in the treatment of asthma. Further methodologically strong and large-scale randomised controlled trials are needed in order to address the question of the effectiveness of vitamin C in children with asthma but some outcome data showed effectiveness on lung function, symptom scores, IgE levels and inhaled steroid use. One small study showed a significant difference in % drop in FEV1 post-exercise, according to the study of "Vitamin C supplementation for asthma" by Kaur B, Rowe BH, Arnold E.(3)

4. Folate
In the investigation of the prevalence and multifactorial etiology of anemia among Indian human immunodeficiency virus (HIV)-infected children and its effect on anemia, found that Anemia, particularly iron deficiency anemia and anemia of inflammation, is highly prevalent among children with HIV infection. Micronutrient supplements (iron and, folate) combined with ART(antiretroviral therapy) improved anemia in HIV-infected children, according to "The prevalence and etiology of anemia among HIV-infected children in India" by Shet A, Arumugam K, Rajagopalan N, Dinakar C, Krishnamurthy S, Mehta S, Shet AS.(4)

5. 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 Polish]" by Rahnama M, Błoniarz J, Zareba S, Swiatkowski W.(1)and regulating blood sugar level, according to the study of "[An inadequate intake of manganese may favour insulin resistance in girls]. [Article in Spanish]" by Rodríguez-Rodríguez E, Bermejo LM, López-Sobaler AM, Ortega RM.(2)

Since mustard green contains a measurable amount of vitamin A, it not only protects the epithelial cells against the invasion of bacteria, but heals would faster by inhibiting cell migration and proliferation, according to the study of '[Effect of vitamin A on the adhesive interaction of cells in epithelial tissue].[Article in Russian]' by Chernova TA, Kon' IIa, Bekmuratova II, Melikiants AG, Stepanova LV., posted in PubMed (http://www.ncbi.nlm.nih.gov/pubmed/3433351), researchers found that The data obtained show that vitamin A may serve as a factor modulating intercellular adhesive interactions with tissue specificity.
