Health Benefits
A. Health benefits according to studies
Phenolic antioxidants
In the investigation of
Peanut skins, a byproduct of peanut and its high levels of phenolic antioxidants found that the maximum predicted total phenolic content (TPC), under the optimized conditions (30.8%, 30.9 degrees C, 12 min) was 118 mg of gallic acid equivalents (GAE)/g of skins. MeOH(solvent type) extracts had the highest oxygen radical absorbance capacity (ORAC) activity of 2149 micromol of TE/g followed by EtOH(solvent type) and water under the optimized conditions of 30% MeOH, 52.9 degrees C and 30 min, according to "Optimizing the extraction of phenolic antioxidants from peanut skins using response surface methodology" by Ballard TS, Mallikarjunan P, Zhou K, O'Keefe SF.(a)

Synthetic food ingredients replacement
In the searching of
natural alternatives to synthetic antioxidants and antimicrobials agents as consumers become concerned with currently used compounds found that many of the recent patents concerning peanut phytoalexins focus on this area with patents being submitted for synergistic effects with chemotherapy drugs and treatment of diabetes and hepatitis B. Peanut phytoalexins may not only be able to replace synthetic food ingredients, but may also treat diseases that currently plague the human population, according to "Recent applications of peanut phytoalexins" by Holland KW, O'Keefe SF.(b)

3. A
ntioxidant activity and cytotoxicity
In the observation of
Antioxidant stilbenoids, such as resveratrol, arachidin-1, and arachidin-3, found in prenut and theirs beneficial effects on human health found that oxidation was inhibited at a 14, 7, and 14 μM doses for CPC-purified resveratrol, arachidin-1, and arachidin-3, respectively. Arachidin-1 and arachidin-3 demonstrated cytotoxicity at 27 and 55 μM in RAW 264.7 and HeLa cell lines, respectively; while resveratrol exhibited no cytotoxicity to either cell line. These results demonstrate the integration of a production and purification system for the manufacturing of A. hypogaea-derived stilbenoids, according to "Purification of resveratrol, arachidin-1, and arachidin-3 from hairy root cultures of peanut (Arachis hypogaea) and determination of their antioxidant activity and cytotoxicity" by Abbott JA, Medina-Bolivar F, Martin EM, Engelberth AS, Villagarcia H, Clausen EC, Carrier DJ.(c)

Hypolipidemic and hepatoprotective effects
In the determination of
physicochemical and antioxidant properties of mixture of Flax/Sesame (LS) and Flax/Peanut (LA) and thiers hypolipidemic, antioxidant and hepatoprotective activities, found that Administration of (LS) or (LA) seeds mixture to hypercholesterolemic rats (MS-LSchol and MS-LAchol groups respectively) significantly ameliorated lipid parameters and showed an increase of PUFAs (ALA and LA) and MUFAs and a decrease of SFAs in plasma and liver of MS-LSchol and MS-LAchol groups. Furthermore, malondialdehyde levels decreased and the efficiency of antioxidant defense system was improved compared to CD-chol group. Liver histological sections showed lipid storage in hepatocytes of CD-chol group and an improvement was noted in both supplemented groups. Our results suggested that seeds mixtures of Flax/Sesame and Flax/Peanut have anti-atherogenic and hepatoprotective effects, according to "Hypolipidemic and hepatoprotective seeds mixture diet rich in omega-3 and omega-6 fatty acids" by Makni M, Fetoui H, Garoui el M, Gargouri NK, Jaber H, Makni J, Boudawara T, Zeghal N.(d)

Cardiovascular health
In the classification of
peanut consumption and its efect on lipid profiles, atherogenic index of plasma (AIP) and CHD risk in hypercholesterolaemic men found that peanut consumption significantly reduced the AIP (mean 0.1 (se 0.03) P = 0.01) and CHD estimated risk over 10 years based on systolic and diastolic blood pressures (mean 1.4 % (se 0.5 %) P = 0.004 and mean 2.2 % (se 0.5 %) P < 0.001, respectively) and concluded that short-term peanut consumption might improve lipid profiles, the AIP and CHD risk in free-living hypercholesterolaemic men, according to "Peanut consumption and cardiovascular risk
" by Ghadimi Nouran M, Kimiagar M, Abadi A, Mirzazadeh M, Harrison G.(e)

B. Health benefits according to concentration
1. Manganese
Manganese beside plays an vital role for the proper and normal growth of human bone structure (accodring to the study of "Bone formation within alumina tubes: effect of calcium, manganese, and chromium dopants" by Pabbruwe MB, Standard OC, Sorrell CC, Howlett CR., posted in PubMed (, it also helps to reduce the risk of cancer, (according to the study of "The effects of 3, 4 or 5 amino salicylic acids on manganese-induced neuronal death: ER stress and mitochondrial complexes" by Yoon H, Lee GH, Kim DS, Kim KW, Kim HR, Chae HJ., posted in PubMed ( researchers indicated that the salicylate analogues and the antioxidants did not mediate ER stress in this model. The salicylate analogues reduced reactive oxygen species (ROS) and reversed the deficient mitochondrial membrane potential that was induced by Mn. Taken together, the 3, 4, 5 ASA worked in a similar way, regulating the Mn-induced mitochondrial dysfunction and protecting cells.

2. TryptophanTryptophan 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.(1)

3. Vitamin B3Niacin or vitamin B3 beside is important in production of energy in metabolism of carbohydrate, it also essential for DNA repairing, according to the study of `Niacin deficiency delays DNA excision repair and increases spontaneous and nitrosourea-induced chromosomal instability in rat bone marrow`by Kostecki LM, Thomas M, Linford G, Lizotte M, Toxopeus L, Bartleman AP, Kirkland JB., posted in PubMed (, production of steroid hormones in the adrenal gland, improving blood circulation and lowering the bad cholesterol (LDL) levels., according to the study of `Lowering LDL cholesterol with margarine containing plant stanol/sterol esters: is it still relevant in 2011?`by Doggrell SA., posted in PubMed (

4. FolateIn 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.(II)

5. CopperCopper is best known for its function in regulating the proper growth, utilization of iron, it is also a strong antioxidant, aiding the antioxidant enzyme, superoxide dismutase, and preventing oxidation in the cell membrane, according to the article of antioxidant cancer and diseases, posted in Medical Advisor Journals, in other antioxidants, 1. Copper
