de Oliveira LDL, de Alencar Figueiredo LF. Sorghum phytonutrients and their health benefits: A systematic review from cell to clinical trials. J Food Sci 2024. [PMID: 38517029 DOI: 10.1111/1750-3841.17011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 01/26/2024] [Accepted: 02/14/2024] [Indexed: 03/23/2024]
Abstract
Sorghum is key for global food security due to its genetic variability, resilience, and rich phytonutrient content, which are linked to numerous health benefits. A systematic review assessed the health effects of sorghum by analyzing cell (n = 22), animal (n = 20), and human (n = 7) studies across antioxidant, anti-inflammatory, obesity, cancer, cardiovascular, and diabetes outcomes. This review, involving 42 papers and 177 researchers from 12 countries, collected data from sorghum accessions (acc) and significant effects. Studies used 68 identified and 8 unidentified sorghums, 57% red (n = 20), brown (n = 5), and black (n = 17) pericarp colors, and evaluated whole (n = 31), brans (n = 11), and decorticated grains (n = 2). Colored sorghum, richer in phenolic compounds, especially 3-deoxyanthocyanins and tannins, inhibited cancer cell activities, including proliferation, tumor growth, and ROS activity, and promoted cell cycle arrest and apoptosis. Sorghum elevated HO1 and eNOS expression for cardiovascular, health-reduced platelet aggregation, and modulated platelet microparticles. They also suppressed inflammation markers and decreased lipid accumulation. Animal studies indicated sorghum's potential across antioxidant capacity, cancer and inflammation mitigation, and lipid and glucose metabolism. Translating these findings to human scenarios requires caution, especially considering cell studies do not fully represent polyphenol metabolism. Human studies provided mixed results, indicating antioxidant and potential anti-inflammatory benefits and nuanced effects on glucose and lipid metabolism. The main risks of bias highlighted challenges in quantifying phytonutrients, identifying sorghum acc features, and lack of assessors blinding. Nonetheless, sorghum emerges as a promising functional food for countering chronic diseases in Western diets.

[PMID: 38455221 PMCID: PMC10916587 DOI: 10.1002/fsn3.3856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 11/02/2023] [Accepted: 11/07/2023] [Indexed: 03/09/2024] Open
Abstract
Diet is a modifiable risk factor in the prevention and management of obesity, and various foods have the potential to aid in obesity management by modulating different pathways involved in the disease's pathology. We performed a systematic review of literature, using CINAHL, PubMed, and Google Scholar, focusing on the antiobesity potential of foods crops and functional food products, and their mechanisms of action and clinical evidence. Sixty-four articles were identified, of which 41 investigated food crops, while 23 investigated functional products. Food crops, such as cereals, vegetables, fruits, mushrooms, seaweeds, legumes, herbs, spices, and cocoa seeds, have antiobesity effects through mechanisms such as altering the metabolism of glucolipids by inhibiting enzymes like α-amylase and α-glucosidase, stimulating the bioenergetics of thermogenic fat, modulating gut microbiota, and inhibiting lipogenesis and storage. In addition, developed functional teas, beverages, and yoghurt have antiobesity effects through similar or different mechanisms, such as enhancing energy expenditure and satiety, suppressing adipogenesis and lipolysis, improving glucose and lipid metabolism, and altering hormonal secretion. This review reemphasized the significance of food in the control of obesity, and highlights the distinct methods these explored foods exert their antiobesity effects. In conclusion, foods are safe and effective means of combating obesity without the side effects of conventional drugs, which can help inform dietary choices, assist professionals in providing more accurate advice, and also lead to better understanding of food and its effect on overall health of the public. This approach will eradicate global diseases, especially if more underutilized and indigenous food crops are extensively researched.

Abstract
Sumac sorghum (Sorghum bicolor L. Moench) bran contains polyphenolic compounds with health-promoting properties. Functional food product development can add economic value to sorghum bran, but acceptability may be limited by bitter taste. An acidified cold-brewed sorghum bran beverage was developed, and simplified sweetened (SB) and unsweetened (UB) versions were analyzed for antioxidant profiles (total phenolic content, phenolic profiling via HPLC, condensed tannins, oxygen radical absorbance capacity, and 2,2-diphenyl-1-picrylhydrazyl radical scavenging) and sensory properties. Beverages contained condensed tannins (average of 0.33 mg catechin equivalents per milliliter) along with other flavonoids and demonstrated in vitro antioxidant capacity (3.32-3.96 mmol Trolox equivalents per milliliter). One hundred fourteen consumers, grouped by 6-n-propylthiouracil (bitterness) taster status, rated acceptability (9-point hedonic scales), bitterness intensity (5-point scale), and purchase intent (PI; yes/no) of model beverages. Although the concept was novel, SB was clearly more acceptable to consumers regardless of preference for sweet versus unsweet tea (as a reference product concept). Mean mouthfeel and flavor liking scores were significantly higher for SB (6.2 and 5.1, respectively) than UB (4.8 and 3.0, respectively). Bitterness was suppressed by the sweetness in SB (mean bitterness intensity of 1.8 vs. 2.6 for UB), although 21% of consumers still found it "too bitter." However, consumers' taster status did not affect beverage acceptability nor bitterness perceptions at present phenolic levels (0.53 gallic acid equivalents per milligram). After a sorghum/antioxidant information message, positive PI increased to 56% for SB, impacting more females than males. Enhanced familiarity and effective product messaging can improve acceptability of acidified cold-brewed sorghum bran beverages as a novel functional food product concept. PRACTICAL APPLICATION: New food applications of cereal bran can provide value in terms of byproduct utilization and delivery of health-promoting ingredients. Sorghum bran beverages demonstrated antioxidant activity, and the sweetened formulation showed decreased bitterness and increased acceptability. Consumers were positively influenced by antioxidant information, although most had not previously consumed sorghum.

Food Sci Biotechnol 2023; 32:705-712.

Abstract
Sorghum is a vital cereal source that has various phenolic compounds and potential health-promoting benefits. This study evaluated the phenolic content, antioxidant and anti-obesity effects of sorghum extract (SE) prepared using three solvent systems: 50% (SE50), 80% (SE80), and 100% (SE100) ethanol. The results showed that SE50 exhibited the highest total polyphenol and flavonoid content among the sorghum extracts using different ethanol concentrations as extraction solvents. In addition, SE50 showed significantly higher antioxidant capacity than the other extracts. Interestingly, SE50 significantly inhibited lipid accumulation in 3T3-L1 adipocytes; however, SE80 and SE100 had no beneficial effects. Moreover, SE50 significantly downregulated the mRNA expression levels of adipogenic genes (Cebpα, Pparγ, and Fabp4) and lipogenic genes (Srebp1c, Fas, and Scd1). These results suggest that SE50 is superior to other ethanol extracts in phenolic contents, antioxidant and anti-obesity activities, and it could be used as a nutraceutical for anti-obesity.

Mudjanarko SW, Rahardjo T, Soelistijo SA, Rahmawati S. One-week sorghum ( Sorghum bicolor L.) grain consumption is insufficient to increase adiponectin levels in prediabetic adults. Endocr Regul 2023; 58:11-18.

Abstract
Objective. Adiponectin is an internally produced bioactive compound with a protective role against the insulin resistance-related diseases. Finding an adiponectin modifier can play a beneficial role in preventing the progression of the diseases, particularly in the prediabetic patients, as a high-risk population. This study was undertaken to examine the effect of dietary sorghum grain for a week on the plasma adiponectin levels in prediabetic patients. Methods. The study involved 26 (13+13) participants in both control and intervention groups. The control group maintained their habitual diet of white rice, while the intervention group replaced their habitual diet of white rice with sorghum grain for seven consecutive days. In all participants, the adiponectin concentration was measured before and after the intervention period. Results. Most study subjects had central obesity and dyslipidemia. Adiponectin levels after the intervention period decreased from the baseline in the control and sorghum groups including in all BMI groups. The change of decreasing adiponectin level was greater in the control than the sorghum group and in line with greater BMI in the sorghum group, but statistically insignificant. No significant difference in adiponectin concentrations was found among BMI groups. Conclusion. Sorghum grain consumption for a week is insufficient to increase adiponectin levels in the prediabetic patients. Insulin resistance, central obesity, and dyslipidemia may be the confounding variables that alter the favorable effect of sorghum on adiponectin. Longer sorghum consumption or other interventions may be needed to increase the adiponectin levels in people under these conditions.

Abstract
Polyphenol, one of the major components that exert the therapeutic effect of Chinese herbal medicine (CHM), comprises several categories, including flavonoids, phenolic acids, lignans and stilbenes, and has long been studied in oncology due to its significant efficacy against cancers in vitro and in vivo. Recent evidence has linked this antitumor activity to the role of polyphenols in the modulation of redox homeostasis (e.g., pro/antioxidative effect) in cancer cells. Dysregulation of redox homeostasis could lead to the overproduction of reactive oxygen species (ROS), resulting in oxidative stress, which is essential for many aspects of tumors, such as tumorigenesis, progression, and drug resistance. Thus, investigating the ROS-mediated anticancer properties of polyphenols is beneficial for the discovery and development of novel pharmacologic agents. In this review, we summarized these extensively studied polyphenols and discussed the regulatory mechanisms related to the modulation of redox homeostasis that are involved in their antitumor property. In addition, we discussed novel technologies and strategies that could promote the development of CHM-derived polyphenols to improve their versatile anticancer properties, including the development of novel delivery systems, chemical modification, and combination with other agents.

Abstract
Sorghum and pearl millet are grain crops that can grow in semi-arid climates, with nutritional and bioactive properties superior to those of major cereals such as rice, wheat, and maize. However, these properties vary a lot, depending on the genetic factors, growing conditions, and place of cultivation. Four sorghum and two pearl millet grains cultivars grown in the Far-North region of Cameroon were screened for their chemical composition and antioxidant profile. The proximate and mineral analyses were performed using AOAC standard methods. The antioxidant profile was assayed spectrophotometrically and details on the phenolic compounds were investigated using HPLC. The pearl millet cultivars, especially mouri, showed higher contents of proteins, lipids, ash, calcium, copper, iron, and zinc. The red sorghum specifically exhibited the greatest amounts of total polyphenols (82.22 mg GAE/g DE), total flavonoids (23.82 mg CE/g DE), and total 3-deoxyanthocyanidin (9.06 mg/g DE). The most abundant phenolic compound was gallic acid, while the most frequent were chlorogenic and ferulic acids. The maximum antioxidant activity against DPPH was observed in yellow-pale sorghum (87.71%), followed by red sorghum (81.15%). Among the studied varieties of cereals, mouri pearl millet and red sorghum were the best sources of nutrients and bioactive compounds, respectively. Their consumption should be encouraged to tackle nutrient deficiencies and non-communicable diseases within local populations.
