    Li Y, Zhang Y, Dong L, Li Y, Liu Y, Liu Y, et al.
    Food Chem, 2024 Mar 30;437(Pt 1):137834.
    PMID: 37897817 DOI: 10.1016/j.foodchem.2023.137834
    In this study, strains producing feruloyl esterase were screened by Oxford Cup clear zones method and by evaluating the ability to decompose hydroxycinnamoyl esters. The strain was identified by 16S rDNA molecular biology. The contents of dietary fiber, reducing sugar, water-extractable arabinoxylans, phytic acid, total phenolics, total flavonoid, phenolic compounds composition, microstructure and antioxidant activity in bran before and after fermentation were studied. Eight strains producing feruloyl esterase were screened, among which strain P1 had the strongest ability to decompose hydroxycinnamoyl esters. The strain was identified and named L. fermentum NB02. Compared with unfermented bran, fermented bran exhibited higher contents of soluble dietary fiber, reducing sugar, water-extractable arabinoxylans, total phenolics, total flavonoid, and lower insoluble dietary fiber and phytic acid content. The dense surface structure of bran was destroyed, forming a porous structure. The release of phenolic compounds increased significantly. L. fermentum NB02 fermentation improved the antioxidant capacity of bran.

    Asian Pac J Cancer Prev, 2014;15(14):5959-64.
    PMID: 25081729
    BACKGROUND: Dietary carbohydrate, fiber and sugar intake has been shown to play a role in the etiology of breast cancer, but the findings have been inconsistent and limited to developed countries with higher cancer incidence.

    OBJECTIVE: To examine the association of premenopausal and postmenopausal breast cancer risk with dietary carbohydrate, fiber and sugar intake.

    MATERIALS AND METHODS: This population based case-control study was conducted in Malaysia with 382 breast cancer patients and 382 controls. Food intake pattern was assessed via an interviewer-administered food frequency questionnaire. Logistic regression was used to compute odds ratios (OR) with 95% confidence intervals (CI) and a broad range of potential confounders were included in analysis.

    RESULTS: A significant two fold increased risk of breast cancer among premenopausal (OR Q4 to Q1=1.93, 95%CI: 1.53-2.61, p-trend=0.001) and postmenopausal (OR Q4 to Q1=1.87, 95%CI: 1.03-2.61, p-trend=0.045) women was observed in the highest quartile of sugar. A higher intake of dietary fiber was associated with a significantly lower breast cancer risk among both premenopausal (OR Q4 to Q1=0.31, 95%CI: 0.12-0.79, p-trend=0.009) and postmenopausal (OR Q4 to Q1=0.23, 95%CI: 0.07-0.76, p-trend=0.031) women.

    CONCLUSIONS: Sugar and dietary fiber intake were independently related to pre- and postmenopausal breast cancer risk. However, no association was observed for dietary carbohydrate intake.

    Bhat R, binti Yahya N
    Food Chem, 2014 Aug 1;156:42-9.
    PMID: 24629936 DOI: 10.1016/j.foodchem.2014.01.063
    Belinjau (Gnetum gnemon L.) seed flour was evaluated for nutritional composition, antioxidant activity and functional properties. Seed flour was found to be rich in protein (19.0g/100g), crude fibre (8.66g/100g), carbohydrates (64.1%), total dietary fibre (14.5%) and encompassed adequate amounts of essential amino acids, fatty acids and minerals. Antioxidant compounds such as total phenols (15.1 and 12.6mgGAE/100g), tannins (35.6 and 16.1mgCE/100g) and flavonoids (709 and 81.6mgCEQ/100g) were higher in ethanolic extracts over aqueous extracts, respectively. Inhibition of DPPH was high in ethanol extracts (48.9%) compared to aqueous extracts (19.7%), whereas aqueous extracts showed a higher FRAP value compared to ethanol extracts (0.98 and 0.61mmolFe(II)/100g, respectively). Results on functional properties revealed acceptable water and oil absorption capacities (5.51 and 1.98g/g, respectively), emulsion capacity and stability (15.3% and 6.90%, respectively), and foaming capacity (5.78%). FTIR spectral analysis showed seed flour to encompass major functional groups such as: amines, amides, amino acids, polysaccharides, carboxylic acids, esters and lipids. As belinjau seed flour possesses a rich nutraceutical value, it has high potential to be used as a basic raw material to develop new low cost nutritious functional foods.

  4. Fulltext Preventive inositol hexaphosphate extracted from rice bran inhibits colorectal cancer through involvement of Wnt/β-catenin and COX-2 pathways
    Shafie NH, Mohd Esa N, Ithnin H, Md Akim A, Saad N, Pandurangan AK
    Biomed Res Int, 2013;2013:681027.
    PMID: 24260743 DOI: 10.1155/2013/681027
    Nutritional or dietary factors have drawn attention due to their potential as an effective chemopreventive agent, which is considered a more rational strategy in cancer treatment. This study was designed to evaluate the effect of IP₆ extracted from rice bran on azoxymethane- (AOM-) induced colorectal cancer (CRC) in rats. Initially, male Sprague Dawley rats were divided into 5 groups, with 6 rats in each group. The rats received two intraperitoneal (i.p.) injections of AOM in saline (15 mg/kg body weight) over a 2-week period to induce CRC. IP₆ was given in three concentrations, 0.2% (w/v), 0.5% (w/v), and 1.0% (w/v), via drinking water for 16 weeks. The deregulation of the Wnt/β-catenin signaling pathway and the expression of cyclooxygenase (COX)-2 have been implicated in colorectal tumorigenesis. β-Catenin and COX-2 expressions were analysed using the quantitative RT-PCR and Western blotting. Herein, we reported that the administration of IP₆ markedly suppressed the incidence of tumors when compared to the control. Interestingly, the administration of IP₆ had also markedly decreased β-catenin and COX-2 in colon tumors. Thus, the downregulation of β-catenin and COX-2 could play a role in inhibiting the CRC development induced by IP₆ and thereby act as a potent anticancer agent.

  5. Fulltext Proximate composition, nutritional attributes and mineral composition of Peperomia pellucida L. (Ketumpangan Air) grown in Malaysia
    Ooi DJ, Iqbal S, Ismail M
    Molecules, 2012 Sep 17;17(9):11139-45.
    PMID: 22986924 DOI: 10.3390/molecules170911139
    This study presents the proximate and mineral composition of Peperomia pellucida L., an underexploited weed plant in Malaysia. Proximate analysis was performed using standard AOAC methods and mineral contents were determined using atomic absorption spectrometry. The results indicated Peperomia pellucida to be rich in crude protein, carbohydrate and total ash contents. The high amount of total ash (31.22%)suggests a high-value mineral composition comprising potassium, calcium and iron as the main elements. The present study inferred that Peperomia pellucida would serve as a good source of protein and energy as well as micronutrients in the form of a leafy vegetable for human consumption.

  6. Nutritional and sensory quality evaluation of sponge cake prepared by incorporation of high dietary fiber containing mango (Mangifera indica var. Chokanan) pulp and peel flours
    Aziah AA, Min WL, Bhat R
    Int J Food Sci Nutr, 2011 Sep;62(6):559-67.
    PMID: 21534889 DOI: 10.3109/09637486.2011.562883
    Sponge cake prepared by partial substitution of wheat flour with mango pulp and mango peel flours (MPuF and MPeF, respectively) at different concentrations (control, 5%, 10%, 20% or 30%) were investigated for the physico-chemical, nutritional and organoleptic characteristics. Results showed sponge cake incorporated with MPuF and MPeF to have high dietary fiber with low fat, calorie, hydrolysis and predicted glycemic index compared with the control. Increasing the levels of MPuF and MPeF in sponge cake had significant impact on the volume, firmness and color. Sensory evaluation showed sponge cake formulated with 10% MPuF and 10% MPeF to be the most acceptable. MPeF and MPuF have high potential as fiber-rich ingredients and can be utilized in the preparation of cake and other bakery products to improve the nutritional qualities.

  7. Fulltext Contribution of diet and major depression to incidence of acute myocardial infarction (AMI)
    Yary T, Soleimannejad K, Abd Rahim F, Kandiah M, Aazami S, Poor SJ, et al.
    Lipids Health Dis, 2010;9:133.
    PMID: 21087475 DOI: 10.1186/1476-511X-9-133
    BACKGROUND: Despite significant improvements in the treatment of coronary heart disease (CHD), it is still a major cause of mortality and morbidity among the Iranian population. Epidemiological studies have documented that risk factors including smoking and the biochemical profile are responsible for the development of acute myocardial infarction (AMI). Psychological factors have been discussed as potential risk factors for coronary heart disease. Among emotional factors, depression correlates with coronary heart disease, particularly myocardial infarction.
    METHODS: This case-control study was conducted on 120 cases (69 males and 51 females) of acute myocardial infarction (AMI) and 120 controls, with a mean age of 62.48 ± 15.39 years. Cases and controls were matched by age, residence and sex.
    RESULTS: The results revealed that severe depression was independently associated with the risk of AMI (P = 0.025, OR = 2.6, 95% CI 1.1-5.8). The analysis of variables indicated that risk factors for developing depression were unmarried, low levels of polyunsaturated fatty acids (PUFAs), total dietary fiber (TDF) and carbohydrates. The levels of these dietary factors were lowest in severely depressed patients compared to those categorised as moderate or mild cases. Furthermore, severely depressed subjects were associated with higher levels of total cholesterol, high systolic blood pressure (SBP) and WHR. Age, income, a family history of coronary heart disease, education level, sex, employment and smoking were not associated with severe depression.
    CONCLUSION: The present study demonstrated that severe depression symptoms are independent risk factors for AMI. Furthermore, severe depression was associated with an unhealthy diet and AMI risk factors.

    Fung WY, Yuen KH, Liong MT
    J Agric Food Chem, 2010 Jul 14;58(13):8077-84.
    PMID: 20568772 DOI: 10.1021/jf1012506
    Oil palm trunk (OPT), oil palm frond (OPF), and okara are agrowastes generated abundantly by the palm oil and soy industries. There are vast potentials for these fibrous biomass rather than disposal at landfills or incineration. Fibrous materials (FM) and alkali-treated fibrous residues (FR) were produced from the selected wastes and subsequently characterized. Functional properties such as emulsifying properties, mineral-binding capacity, and free radical scavenging activity were also evaluated for possible development of functional products. Supernatants (FS) generated from the alkaline treatment contained soluble fractions of fibers and were also characterized and used for the production of nanofibers. Okara FM had the highest (P < 0.05) protein (31.5%) and fat (12.2%) contents, which were significantly reduced following alkali treatment. The treatment also increased total dietary fiber (TDF) in okara by 107.9%, in OPT by 67.2%, and in OPF by 25.1%. The increased fiber fractions in FR enhanced functional properties such as water-holding capacities and oil-holding capacities. Okara displayed the highest (P < 0.05) emulsifying properties compared to OPT and OPF. High IDF content of OPT and OPF contributed to high antioxidant activities (377.2 and 367.8% higher than that of okara, respectively; P < 0.05). The soluble fraction from alkali treatment of fibers was successfully electrospun into nanofibers, which can be further developed into nanoencapsulants for bioactive compound or drug delivery.

    Mazaheri H, Lee KT, Bhatia S, Mohamed AR
    Bioresour Technol, 2010 Dec;101(23):9335-41.
    PMID: 20656481 DOI: 10.1016/j.biortech.2010.07.004
    Thermal decomposition of oil palm fruit press fiber (FPF) into a liquid product (LP) was achieved using subcritical water treatment in the presence of sodium hydroxide in a high pressure batch reactor. This study uses experimental design and process optimisation tools to maximise the LP yield using response surface methodology (RSM) with central composite rotatable design (CCRD). The independent variables were temperature, residence time, particle size, specimen loading, and additive loading. The mathematical model that was developed fit the experimental results well for all of the response variables that were studied. The optimal conditions were found to be a temperature of 551 K, a residence time of 40 min, a particle size of 710-1000 microm, a specimen loading of 5 g, and a additive loading of 9 wt.% to achieve a LP yield of 76.16%.

  10. Chemical and physicochemical characterization of agrowaste fibrous materials and residues
    Kuan YH, Liong MT
    J Agric Food Chem, 2008 Oct 8;56(19):9252-7.
    PMID: 18788708 DOI: 10.1021/jf802011j
    The objective of this study was to evaluate the chemical, physicochemical, and functional properties of agrowastes derived from okara ( Glycine max), corn cob ( Zea mays sp.), wheat straw ( Triticum sp.), and rice husk ( Oryza sativa) for potential applications in foods. The fibrous materials (FM) were treated with alkali to yield fibrous residues (FR). Rice husk contained the highest ash content (FM, 8.56%; FR, 9.04%) and lowest lightness in color (FM, 67.63; FR, 63.46), possibly due to the abundance of mineral constituents. Corn cob contained the highest amount of soluble dietary fiber (SDF), whereas okara had the highest total dietary fiber (TDF). The high dietary fiber fractions of corn cob and okara also contributed to the highest water- and oil-holding capacities, emulsifying activities, and emulsion stabilities for both FM and FR samples. These results indicate that these agrowastes could be utilized as functional ingredients in foods.

  11. Whole-grain dietary recommendations: the need for a unified global approach
    Seal CJ, Nugent AP, Tee ES, Thielecke F
    Br J Nutr, 2016 06;115(11):2031-8.
    PMID: 27082494 DOI: 10.1017/S0007114516001161
    Increased whole-grain (WG) consumption reduces the risk of CVD, type 2 diabetes and some cancers, is related to reduced body weight and weight gain and is related to improved intestinal health. Definitions of 'WG' and 'WG food' are proposed and used in some countries but are not consistent. Many countries promote WG consumption, but the emphasis given and the messages used vary. We surveyed dietary recommendations of fifty-three countries for mentions of WG to assess the extent, rationale and diversity in emphasis and wording of any recommendations. If present, recommendations were classified as either 'primary', where the recommendation was specific for WG, or 'secondary', where recommendations were made in order to achieve another (primary) target, most often dietary fibre intake. In total, 127 organisations were screened, including government, non-governmental organisations, charities and professional bodies, the WHO and European Food Safety Authority, of which forty-nine including WHO provide a WG intake recommendation. Recommendations ranged from 'specific' with specified target amounts (e.g. x g WG/d), 'semi-quantitative' where intake was linked to intake of cereal/carbohydrate foods with proportions of WG suggested (e.g. x servings of cereals of which y servings should be WG) to 'non-specific' based on 'eating more' WG or 'choosing WG where possible'. This lack of a harmonised message may result in confusion for the consumer, lessen the impact of public health messages and pose barriers to trade in the food industry. A science-based consensus or expert opinion on WG recommendations is needed, with a global reach to guide public health decision making and increase WG consumption globally.

  12. Fulltext Randomised clinical trial: mixed soluble/insoluble fibre vs. psyllium for chronic constipation
    Erdogan A, Rao SS, Thiruvaiyaru D, Lee YY, Coss Adame E, Valestin J, et al.
    Aliment Pharmacol Ther, 2016 07;44(1):35-44.
    PMID: 27125883 DOI: 10.1111/apt.13647
    BACKGROUND: Fibre supplements are useful, but whether a plum-derived mixed fibre that contains both soluble and insoluble fibre improves constipation is unknown.

    AIM: To investigate the efficacy and tolerability of mixed soluble/insoluble fibre vs. psyllium in a randomized double-blind controlled trial.

    METHODS: Constipated patients (Rome III) received mixed fibre or psyllium, 5 g b.d., for 4 weeks. Daily symptoms and stool habit were assessed using stool diary. Subjects with ≥1 complete spontaneous bowel movement/week above baseline for ≥2/4 weeks were considered responders. Secondary outcome measures included stool consistency, bowel satisfaction, straining, gas, bloating, taste, dissolvability and quality of life (QoL).

    RESULTS: Seventy-two subjects (mixed fibre = 40; psyllium = 32) were enrolled and two from psyllium group withdrew. The mean complete spontaneous bowel movement/week increased with both mixed fibre (P < 0.0001) and psyllium (P = 0.0002) without group difference. There were 30 (75%) responders with mixed fibre and 24 (75%) with psyllium (P = 0.9). Stool consistency increased (P = 0.04), straining (P = 0.006) and bloating scores decreased (P = 0.02) without group differences. Significantly more patients reported improvement in flatulence (53% vs. 25%, P = 0.01) and felt that mixed fibre dissolved better (P = 0.02) compared to psyllium. QoL improved (P = 0.0125) with both treatments without group differences.

    CONCLUSIONS: Mixed fibre and psyllium were equally efficacious in improving constipation and QoL. Mixed fibre was more effective in relieving flatulence, bloating and dissolved better. Mixed fibre is effective and well tolerated.

    Twelve Jermasia kids were individually housed in pens to study the effects of soywaste on growth performance and carcass characteristics and to compare such effects with commercial pellet. Kids were divided into a pellet group and a soywaste group, including six kids (3 males and 3 females) in each group. Pellet or soywaste was offered to kids at a rate of 2.0 % dry matter (DM) of body weight/day in addition to Napier grass ad libitum. In last 10 days of experiment, kids were housed in metabolism crates for faeces collection. At the end of the experiment, three males from each group were slaughtered. Kids fed soywaste diet consumed more grass and neutral detergent fibre (NDF) than those fed pellet. The same trend was found for the digestibilities of DM, organic matter (OM) and NDF. Conversely, kids fed soywaste diet consumed less soywaste supplement than kids fed pellet. No treatment effects were observed on total intakes of DM, OM and crude protein (CP) including CP digestibility. Similarly, no effects were found on carcass and non-carcass components, except for lean, lean to fat ratio and kidney weight which were higher for kids fed soywaste diet. Results indicate that soywaste is effective as a feed for growing kids.

    Comp. Biochem. Physiol. A Physiol., 1995 May;111(1):177-82.
    PMID: 7735907
    Voluntary food intake, digestibility and water turnover were determined in adult Malaysian lesser mouse-deer (Tragulus javanicus) given unlimited access to lundai foliage (Sapium baccatum). Daily dry matter (DM) intake was 42.4 g/kg metabolic live mass (M0.73) or 3.7% M. Digestible energy intake was 853 kJ/day (571 kJ metabolisable energy per M0.73), calculated to be used with 79% efficiency. Apparent digestibility (%) of organic matter was 83.8, crude fibre 63.7, acid detergent fibre 60.5, neutral detergent fibre 72.1 and crude protein 65.0. Urinary excretion of the purine derivative, allantoin, was 0.05 mg/g digestible DM intake suggesting rumen microbial yield efficiency may be lower than in other ruminant species. Total water intake was 182 ml/M0.82. The body-water content of the fed mouse-deer, from tritiated water dilution, was 77% M, consistent with a very lean carcass. Turnover of body water was 17% per day. The mouse-deer produced relatively dry, well-defined faecal pellets.

    Fruits are important food commodities that can be consumed either raw or processed and are valued for their taste, nutrients, and healthy compounds. Mangifera pajang Kosterm (bambangan) is an underutilized fruit found in Malaysia (Sabah and Sarawak), Brunei, and Indonesia (Kalimantan). It is highly fibrous and juicy with an aromatic flavour and strong smell. In recent years, bambangan fruit has been gaining more attention due to its high fibre, carotenoid content, antioxidant properties, phytochemicals, and medicinal usages. Therefore, the production, trade, and consumption of bambangan fruit could be increased significantly, both domestically and internationally, because of its nutritional value. The identification and quantification of bioactive compounds in bambangan fruit has led to considerable interest among scientists. Bambangan fruit and its waste, especially its seeds and peels, are considered cheap sources of valuable food and are considered nutraceutical ingredients that could be used to prevent various diseases. The use of bambangan fruit waste co-products for the production of bioactive components is an important step towards sustainable development. This is an updated report on the nutritional composition and health-promoting phytochemicals of bambangan fruit and its co-products that explores their potential utilization. This review reveals that bambangan fruit and its co-products could be used as ingredients of dietary fibre powder or could be incorporated into food products (biscuits and macaroni) to enhance their nutraceutical properties.

    PMID: 32278601 DOI: 10.1016/j.ijbiomac.2020.04.015
    Olive fiber is a renewable natural fiber which has potential as an alternative biomass for extraction of microcrystalline cellulose (MCC). MCC has been widely applied in various industries owing to its small dimensional size for ease of reactive fabrication process. At present study, a serial treatments of bleaching, alkaline and acid hydrolysis was employed to extract OL-BLF, OL-PUF, and OL-MCC respectively from olive stem fiber. In morphology examination, a feature of short micro-crystallite particles was obtained for OL-MCC. The particle size was found gradually reducing from OL-PUF (305.31 μm) to OL-MCC (156.06 μm) due to the disintegration of cellulose fibrils. From physicochemical analysis, most lignin and hemicellulose components had been removed from OL-BLF to form OL-PUF with individually fibril structure. The elemental analysis revealed that highly pure cellulose component was obtained for OL-MCC. Also, the rigidity had been improved from OL-BLF to OL-PUF, while with the highest for OL-MCC with 74.2% crystallinity, endowing it as a reliable load-bearing agent. As for thermal analysis, OL-MCC had the most stable heat resistance in among the chemically-treated fibers. Therefore, olive MCC could act as a promising reinforcing agent to withstand harsh conditions for variety fields of composite applications.

    PMID: 22691738 MyJurnal
    A case control study to determine the association of dietary fibre and cancer among Malaysians. It was conducted among 100 newly-diagnosed cancer patients admitted to the Radiotherapy and Oncology Ward, Hospital Kuala Lumpur. A total of 100 controls matched with the cases for age, sex and ethnic origin were selected from the Outpatient Health Clinic in Sentul. The subjects were interviewed to obtain information on their habitual dietary intakes and lifestyles. Family history of cancer, smoking habits, and alcohol consumption were found to be significant risk factors for cancer (p<0.05 for all parameters). The mean intake of total energy was higher among men with nasopharyngeal cancer and women with gastrointestinal cancer as compared to their controls (p<0.05 for both parameters). The percentage of energy contribution from fat was higher among cases (35%) than controls (32.1%). The mean dietary fibre intake among cases (10.86 ± 8.90 g/d) was apparently lower than the controls (13.22 ± 5.99 g/d), with significant differences noted for breast cancer and also nasopharyngeal cancer. Women with low fibre intake (<10g/d) had a 2.2 times higher risk of getting breast cancer. There is a need to educate the public to adhere to a wholesome diet, in particular to increase the consumption of high-fibre food for disease prevention.

    Cancer is a significant global health concern affecting men and women worldwide. Although current chemopreventive drugs could inhibit the growth of cancer cells, they exert many adverse side effects. Dietary factor plays a crucial role in the management of cancers and has drawn the attention of researchers to be used as an option to combat this disease. Both in vitro and in vivo studies showed that rice and its by-products display encouraging results in the prevention of this disease. The mechanism of anticancer effect is suggested partly through potentiation of bioactive compounds like vitamin E, phytic acid, γ-aminobutyric acid (GABA), γ-oryzanol, and phenolics. Nevertheless, the bioactivity of rice and its by-products is still incompletely understood. In this review, we present the findings from a preclinical study both in in vitro and in animal experiments on the promising role of rice by-products with focus on cancer prevention.

    This study investigates the cultivation of Ganoderma lucidum using different agricultural biomasses from Malaysia. Five different combinations of rubber wood sawdust, empty fruit bunch fiber, and mesocarp fiber from oil palm, alone and in combination, were used to cultivate G. lucidum. Although all the substrate combinations worked well to grow the mushroom, the highest biological efficiency was obtained from the combination of empty fruit bunch fiber with sawdust. A total yield of 27% was obtained from empty fruit bunch fiber with sawdust, followed by sawdust (26%), empty fruit bunch fiber (19%), mesocarp fiber with sawdust (19%), and mesocarp fiber (16%). The quality of mushrooms was proved by proximate analysis and detection of phenolic compounds and flavonoids. The antioxidant activity verified by DPPH, ferric-reducing ability of plasma, and ABTS analyses revealed that the empty fruit bunch fiber with sawdust had higher activity than the other substrates.
