A stereoselective synthesis of N-glycosyl amides was studied from available N-glycosyl oxazolines prepared by Ritter-like reactions of protected sugar acetonides. Hydrolysis reactions of the protected pentofuranosyl and hexafuranosyl oxazolines, as precursors of glycosyl amine derivatives, were carried out in the presence of silica gel in chloroform to giveN-α- and β-glycosyl amides in good yields after column chromatography on silica gel. Access to selectively blocked N-α-xylo-, -ribo-, β-arabino-furanosyl, α-glyco-, α-allo-furanosyl, α- and β-galactopyranosyl amides (twelve examples) useful for preparing modified N-glycosides was accomplished through a mild hydrolysis of sugar oxazolines with 2-alkyl substituents in acidic and neutral conditions. To further explore the scope of the BF3.Et2O-mediated approach developed for N-furanosyl oxazolines, a stereoselective synthesis of protected N-α-hexopyranosyl oxazoline was fulfilled in a high yield from d-galactopyranose diacetonide derivative. The Ritter-like promoted reaction between D-arabinose and benzonitrile afforded 2-phenyl-β-d-arabinofurano-(1,2-d)-2-oxazoline as the main product. In acetonitrile the BF3.Et2O-KHF2-assisted reactions of unprotected native sugars were found to result in the formation of mixtures of N-furanosyl and pyranosyl acetamides.

The currently reported study employed the curiously named (but simple) quantitative, nondestructive technique of Multiple Attenuated Internal Reflection InfraRed (MAIR-IR) spectroscopy to assess daily variations of both saliva and vaginal secretions from a panel of consenting volunteers. The project goal was to determine whether the protein-to-carbohydrate (starch) ratio, determined by MAIR-IR analysis of salivary and vaginal secretions is an objective measure of the co-variation of mucinous secretions with daily menstrual cycle. Overall, the spectral data were found to provide valid signatures of vaginal mucus chemical changes that also correlated with cyclic periods of presumed fertility, such periods exhibiting repeat times of 14-16 days and 27-29 days in the thoroughly analyzed records. At mid-cycle, associated with ovulatory events, the protein-to-carbohydrate ratio of vaginal mucin maximizes. Higher carbohydrate ratios are associated with stiffer cervical mucus plug formation, which usually prevents infection, spontaneous abortion, and pre-term birth, but may also be responsible for infertility. Mucin relaxation compounds, such as the FDA-approved oral rinse, delmopinol, may induce fertility in such cases.

A global increase in incidence of chronic liver disease (CLD) indicated the necessity of dietary and lifestyle modification. Low glycemic index (GI) diet was reported to have a significant role in controlling diabetes caused by liver dysfunction. The International Standards Organisation (ISO) has standardized the determination of GI of a food in healthy individuals. This study aimed to estimate GI value of a high protein, energy dense liver nutritional supplement. This cross-over randomized controlled study randomly allotted 15 participants to consume either reference food 27.5 gm glucose (glucose monohydrate) or 77 gm nutritional supplement (equivalent to 25 gm of available carbohydrates); switching to another arm was done after 3 days wash-out period. After overnight fast, blood samples were collected at 15, 30, 45 and 60 minutes post-consumption of s upplement or reference food. The GI was calculated from the incremental area under the blood glucose response elicited by the nutritional supplement as a percentage of the response after consumption of 27.5 gm of glucose (glucose monohydrate) by the same participant using a standard formula. Mean GI of the nutritional supplementwas estimated as 11.4 ± 2.4.With the consumption of this nutritional supplement, the blood glucose levels were reduced at all postprandial time points, compared to the reference food. The liver nutritional supplement tested has a low GI, and comparatively slower and more sustained blood glucose response. Therefore, it can be used in patients with CLD to prevent CLD-associated metabolic complications and improve health outcomes and quality of life.

Non-nutritive sweeteners are used as adjuncts in treating patients with diabetes to reduce carbohydrate intake. Monk fruit is an FDA-approved1 natural NNS2-. There is no information regarding the use of monk fruit in individuals with T2DM3. The primary objective was to compare the glycemic response to sucrose and monk fruit in individuals with and without T2DM. Twenty-six individuals with T2DM and 29 without DM4 underwent two oral glucose tolerance tests5 after a 250-ml sucrose- or monk fruit-sweetened beverage. Glucose levels were measured at 0, 30, 60, 90, and 120 minutes. An appetite scale was used before and after the procedure. Insulin levels were measured in ten randomly selected individuals from the control group. The glucose levels at 30 and 120 min were significantly lower in both groups in the monk fruit-OGTT. There was a peak response in the T2DM group at 90 min (median, IQR, 247 mg/dL, 203-293) with the sucrose OGTT, while no peak response was seen in the monk fruit OGTT. There were no differences between sweeteners in terms of appetite evaluation. The postprandial effect on insulin levels was flat with the monk fruit-sweetened beverage. In contrast, there was a significantly higher spike with the sucrose-sweetened beverage. In conclusion, monk fruit does not increase glucose levels in individuals with T2DM; thus, it could be a safe alternative as a substitute food sweetener.

The current study was intended to evaluate the chemical composition, functional properties, of some cucurbits seed. watermelon (Citrullus lanatus), and Pumpkin (Cucurbita maxima), were studied. Proximate analysis gave 17.09% -17.07% protein, 35.55%-39.0% fat,6.00% - 5.5% total ash, 24.9%-2.6% crude fibre, and 10.60% - 28.83% carbohydrate, for Pumpkin and Watermelon seed flour respectively. The seeds are rich in protein, crude fat, and crude fiber. nutritional value in the seed can be recommended on daily allowance, maintenance of good nutritional status and good health. The functional properties of the seed revealed that water and oil absorption capacities for the seed were 3.20 - 5.60 (Ml/g) and 3.93 -3.50 (Ml/g) for Watermelon and Pumpkin seed flour respectively. Foam capacity and bulk density for the seed were 9.67 % -19.0 % and 0.77 (g/ml) -1.5(g/ml). for Pumpkin and Watermelon seed flour respectively. Water and fat absorption capacities, and foam capacity were fairly good in all seeds. However, Pumpkin seed flour gave good functional properties compare to watermelon seed flour. The oil of watermelon and Pumpkin are acceptable according to its chemical properties. The seeds contained high amounts of K, Mg, Na, P and Ca. The obtained results revealed that the seeds presented an alternative source of vegetable oil. Seeds could be added to food systems such as bakery products.

Upon considering the anticancer effects of larger oligomeric proanthocyanidins and observing various papers reporting the high resolution mass spectroscopy of the oligomeric proanthocyanidins, it is determined that the unusual 13C enrichment in some plant oligomeric proanthocyanidins may be responsible for the anticancer activities of these food products. Such correlation of the 13C in the oligomeric proanthocyanidins also correlate with their scavenging of free-radicals, anti-virial and anti-bacterial properties. Proanthocyanidins in grape seeds are observed to have high enrichment in heavy isotopes of 2H, 13C, 15N and/or 17O. Mass analysis of DNA from human cancer cells are compared to normal human cells and cancer cells show bond specific enrichment of heavy isotopes in nucleotides G, A, T and C. On such basis, this study suggests possible stronger interactions of proanthocyanidins with DNA in cancer verses DNA in normal cells due to heavy isotope bond specific enrichments in both proanthocyanidins and the cancer DNA. Such 13C interactions from oligomeric proanthocyanidins with nucleic acids and proteins involved in replications, transcriptions and translations in cancer cells for interacting and chemically altering anabolism and cell division of the cancer cells are consistent with the author’s mechanism for normal cell to cancer cell transformations via possible replacements of primordial 1H, 12C, 14N, 16O, and 24Mg isotopes by nonprimordial 2H, 13C, 15N, and 17O and 25Mg isotopes in the proteins and nucleic acids. Such is also consistent with the proposed treatment for cancer by the author by use of foods containing proteins, nucleic acids, carbohydrates and/or drug molecules enriched with the nonprimordial isotopes of 2H, 13C, 15N, and 17O and 25Mg.

Colorectal cancer (CRC) is a menace in the global public health system. According to GLOBOCAN reports, colorectal cancer is the second most diagnosed cancer in the world with more than 1.9 million cases and 935,000 deaths in 2020 alone. Diet plays a key role in exposing humans to environmental carcinogens and anti-carcinogens, consequently mitigating or aiding in the development of various cancers. CRC is most prevalent in western countries with a high intake of saturated fats, refined carbohydrates, and processed meat. CRC was an extremely rare disease in Africa some decades ago, but the situation is fast changing. The traditional African diet consists of leafy, roots and cruciferous vegetables, fruits, roots, tubers and plantains, legumes, whole grains, and spices, all of which have been shown to possess protective effects against CRC. However, the effect of urbanization has contributed to the shift of dietary choices among the African population to consuming more ultra-processed foods with high levels of unhealthy components that have originated from colorectal cancer prevalent regions. This review evaluates the current nutritional challenges of the African diet to colorectal cancer and the potential roles of the traditional African diets and lifestyle modification in the prevention and management of colorectal cancer.

A systematic use of biofertilizers can improve both the quality of a farming system and the parameters of milk. Some issues related to biofertilization experiments on six farms in the Po Valley (NW Italy) involved in the production of milk from dairy cattle fed maize silage or grazed on hay produced from permanent meadows are reported in this paper. Biofertilized maize was found to lower the live stem pH by about 2.3%, and NIR spectroscopy foreshadowing major changes in the composition. Overall, the plant silage was improved in quantity (+10%) but also in quality, as shown by the delayed maturity stage of the leaves (crop maturity index -4%), the lower indigestible NDF content (-7%), and the higher digestible carbohydrates and protein in the whole plants. Such favorable feeding conditions, together with the improved palatability of the feed ration, boosted the nutrient values of the protein (+4.6%) and fat contents (+5.7%) in the milk. Moreover, the functional properties of the milk were ameliorated, as testified by the higher levels of vitamin A (+27%) and vitamin E (+25%) and the reduced levels of saturated fatty acids (-6%), especially myristic (-18%) and stearic (-32%) acids, while the unsaturated acids increased by 15%. As far as economy aspects are concerned, the biofertilization of maize for silage has led to consistent rewards pertaining to the marginal price of the milk, which in turn has led to a value chain increase of about 9%, because of the fields cultivation, but mainly of the cow transformation in milk quality issues. On another farm, intensive maize was substituted with permanent biofertilized meadows, over a greening path, and a + 17% value chain increase was obtained that already derived mainly from the best price for milk quality parameters. Such an evolutionary leap toward a new vision of sustainable agriculture for the environment and for animals, in which a better quality of products, animal welfare and company budget are combined with soil biofertilization, can be considered a bonanza.

Background Nutritional status of adolescent girls is very crucial for their health and has a great impact on the quality of the next generation. The present study aimed to investigate the nutritional status and nutrition-related knowledge among urban adolescent girls in Bangladesh. Methods A cross-sectional study involving a total 500 of adolescent girls (aged 10-19) from four schools and colleges in Dhaka city. Socio-demographic, anthropometric and nutrition-related information was collected by semi-structured questionnaires. In addition, 24 hours food recall and food frequency questionnaire was used to assess the dietary intake. Results The ages of the early adolescent and late adolescent girls yrs (Mean ± SD) were 12±1 and 17±1 respectively. The mean (±SD) BMI of the early adolescent and late adolescent was 21.12±0.32 and 22.10±3.89 correspondingly. Among the early adolescent girls, the nutritional knowledge score was about 62% (moderate), 87% had a positive attitude and 72% had good practices in their daily lives. Whereas among the late adolescent girls, the nutritional knowledge score was about 57% (moderate), 90% showed a positive attitude and 61% had good practices. Among the subject, the average calorie intake was 1491 kcal, which was 24% lower than RDA. The Carbohydrate intake was lower than the RDA but the protein and fat intake was higher than the RDA. Conclusions The dietary intake of adolescent girls was found inadequate. Nutrition education and strong motivation can create positive changes in dietary intake. To understand the real phenomena of dietary intake of adolescent girls, further study is necessary to conduct with a large sample size.

With an increased intake of processed carbohydrates and refined sugars, the obesity rate has shot up in the past decade giving rise to mental and physical health problems. These individuals are also the most vulnerable to a number of other diseases including the current pandemic of Covid-19. This paper aims to address the knowledge gap that is required to promote a healthy lifestyle for mental and physical wellbeing. The paper also analyses a number of different studies conducted and helps in understanding obesity as a strong risk factor to various disorders. Despite constant recommendations from healthcare organisations to address the importance of weight regulation, the process to do so often remains uncertain to the general population. The paper analyses the effects of the ketogenic diet for fat loss as well as treating mental illnesses and aims to address the influence of high carbohydrate diets on mental illnesses.

Spices have been frequently added to foods since ancient times, not only to enhance the taste but also as preservatives and medicinal agents. Their usage may be of concern due to possible contamination during processing and handling. The aim of this study was to investigate the physicochemical properties and heavy metals concentrations in some indigenous spices sold at two main markets namely Bodija and Apata markets in Ibadan, Oyo State, Nigeria. A total of eight commonly consumed spices were purposely analyzed for their proximate and mineral composition, physicochemical properties and anti-nutrients contents. Proximate analyses showed that the spices to contained (fresh matter ‘As consumed’) moisture content ranging from 11.74g in thyme to 59.36g/100g in scent leaves. Crude protein, fat, fibre, ash and carbohydrate contents ranged between 3.72 – 15.07g, 1.31 – 8.28g, 1.96 – 11.38g, 1.11 – 7.81g, and 17.80 – 50.77g/100g sample, respectively. All the spices contained high levels of potassium (176.3 – 739.6 mg), sodium (60.6 – 317 mg), calcium (78.5 – 423.9 mg), magnesium (82 – 322.1 mg) and iron (5.78 – 20.10 mg), but low levels of heavy metals – copper (0.17 – 0.68 mg), and manganese (0.32 – 1.05 mg)/100g respectively. Flavonoid was the most abundant phytochemical, while terpene was the least phytochemical in all the samples. The samples had very low concentrations of anti-nutrients, and could pose no threat to human health, as their values were within the regulatory standard. The antioxidants and phytochemicals in the spices can help in building up immunity and prevention of non-communicable diseases, hence, their consumption should be encouraged.

Trichoderma reeseiβ-glucosidase (Bgl1) is one of four enzymes demonstrated to act synergistically to degrade cellulose both in vitro and in vivo. Our work attempted to better understand the substrate specificity and potential biotechnological applications of Bgl1. T. reesei Bgl1H cleaves over 80% of the β-(1-4) and β-(1-3) linkages in β-glucan and 14% of the β-(1-4) linkages in amorphous cellulose, significantly more than any tested bacterial β-glucosidase. Bgl1H cleaves 50% of the β-(1-4) linkages in xyloglucan when supplemented with cellulase and α-xyloside. Approximately 20% conversion to glucose was obtained from insoluble β-(1,3)-linked curdlan using only Bgl1H; addition of a curdlanase resulted in conversion of approximately 70% of the curdlan to glucose. Bgl1H also produces xylose from xylooligosaccharides and debranched xylans. For both glucans and xylans, the relative rates of hydrolysis increase with increasing polysaccharide chain lengths. Bgl1H is able to partially degrade β-glucan in a variety of grain components; addition of endo-acting enzymes improved the enzyme’s performance on these grain components. The ability of this enzyme to produce monosaccharides from undigestible polysaccharides suggest it may have potential in improving utilization of carbohydrates in animal feed, fermentations, and other biotechnological applications.

The potential of Nigerian indigenous tree leaves as vegetable source, pharmaceuticals and other therapeutic materials have been reported. However, Silk cotton (Ceiba pentandra) leaf is still underutilised as vegetable in parts of Nigeria where it exists despite its potential great health benefits. The aim of the study was to assess the micronutrient and phytochemical potential contribution to nutrient intake of its consumers, and acceptability of its cooked soup and sauce ‘as consumed’. Fresh young shoots and leaves of Ceiba pentandra were harvested from Ihitte/Uboma in Imo State, Nigeria. Composite sample of the leaf was prepared and divided into four portions. One portion was labelled as raw sample, and others blanched, cooked to soup and sauce. The four samples were analysed for proximate, minerals, vitamins and phytochemical composition using standard methods of AOAC. Sensory evaluation of soup and sauce was carried out using 9-point hedonic scale with 30 untrained panelists. Data were analysed using ANOVA at p<0.05 Raw Ceiba pentandraleaf contained 80.9g moisture, 3.9g protein, 0.8g fat, 15.3g carbohydrate, 68.40 kcal gross energy, 183.40mg potassium, 119.38mg calcium, 112.99mg phosphorus, and 3.46mg iron/100g sample. The leaf was rich in phytochemicals such as saponins, flavonoid and alkaloids. Raw sample was highest in water-soluble vitamins while the sauce was highest in β-carotene (339.72µg/100g). Cooking the leaf to soup and sauce significantly increased the mineral content of the products (P<0.05) with reduction in water-soluble vitamins and phytochemicals (P<0.05). The sensory attributes of the soup and sauce were generally acceptable to the panelists, with the sauce being more acceptable. The leaf and its products were rich in essential minerals, vitamins and phytochemicals. The sauce retained more nutrients compared to other samples. Inclusion of this underutilised vegetable in diets will reduce micronutrient malnutrition, promote dietary diversity, good health and wellness.

Diabetes mellitus (DM) is a chronic metabolic disorder. Streptozotocin is a naturally occurring cytotoxic chemical, particularly toxic to the pancreas and insulin producing beta cells in mammals and induces diabetes. Glimepiride is a second generation sulfonylurea, used as second-line or add-on treatment options for type 2 diabetes. Fenugreek (Trigonella foenum graecum) seeds have been documented as a traditional plant treatment for diabetes. Soluble dietary fiber of Fenugreek significantly improved oral glucose tolerance in diabetic rats. It also exerts anti-diabetic effects mediated through the inhibition of carbohydrate digestion and absorption and the enhancement of peripheral insulin action. Most herbal remedies can interact with allopathic drugs resulting in altered activity and toxicity. At the same time, herbal remedies might produce the same kind of effects as the drug produce. Current published research information on herb-drug interactions is scanty. So, the aim of this study was to investigate the possible interaction between conventional drug used for the management of diabetes; (Glimepiride) and a traditional herbal remedy; Fenugreek aqueous extract in Streptozotocin induced diabetic male albino rats. In conclusion, combination therapy induces better hematological, biochemical effects and improves the oxidative stress biomarkers and antioxidant enzymes. Histological studies showed better results on some organ functions. The results emphasize the benefit of using the combination of Fenugreek seeds aqueous extracts as supportive complementary anti-diabetic therapy.

In the current study, The GC-MS metabolomics approach was used to evaluate the effect of cypermethrin on the metabolic profile in liver tissue of common carp fish. Fish were exposed to low and high concentrations of cypermethrin (0.1 and 1 µg/L respectively) for 24 and 96 h with subsequent PCA analysis to illustrate the response of the metabolic system after exposure to the pyrethroid. Cypermethrin induced obvious alteration in the intermediates of TCA cycle and encouraged consumption of non-carbohydrate sources in liver at all-time points. Additionally, cypermethrin exposure reduced the level of several amino acids and induced damage to the nucleotides reflecting the effect of cypermethrin on purine metabolism. GC-MS based metabolomics approach is a new and powerful tool to understand the toxicological effects and the underlying mechanism of cypermethrin on fish.

A cohort of Pony Club horses was observed for 13 months with data collected from owner-kept diaries and monthly property visits. All horses studied had access to pasture for all or part of the day. Whilst paddock size was seldom limiting, pasture degradation was evident and observed pasture mass and composition varied greatly. Horses’ body weight indices and body condition scores also varied greatly, closely matching seasonal variations in pasture mass. Increments in bodyweight varied in a non-linear fashion with body condition score. Most horses experienced additional year-round hand-fed supplementation and half of the study horses recorded body condition scores greater than 3.5 out of 5. This suggests that the owners of Pony Club horses did not rely on pasture as the sole source of nutrition, even though, based on estimated energy demands, well-managed pasture can meet the energy requirements of Pony Club horses. Furthermore, the fact that owners appeared not to make horse feeding decisions based on body condition score resulting in obesity, raises health and welfare concerns in this cohort of horses. The inappropriate feeding of supplements observed during times of high pasture growth was a concern. Whilst the ideal pasture for Pony Club horses has not been described, it is likely to differ to those considered ideal for broodmares and other livestock because of these unique health risks associated with high levels of non-structural carbohydrate content in improved pasture species. This study highlights the need to educate owners about recognising unhealthy body conditions of horses and better managing pastures and pasture access to reduce the risk of obesity related disorders, whilst at the same time reducing pasture degradation and supplemental feed costs

Objective: To assess the effect of different treatment approaches on the course of anorexia nervosa (AN) over time. Methods: The subjects were 27 hospitalized AN patients. In our retrospective analysis we compared weight gain in two groups. While one group was treated with a standard oral refeeding protocol (historical control) through January 2013 (N=16), the second group (highly standardized refeeding protocol) received a high energy liquid nutrition and nutritional supplements including omega-3 fatty acids (N=11). Results: On admission, the two groups were comparable in terms of height, weight, age and heart rate. At the end of our monitoring time frame of 25 days, weight gain was 121.4% higher in the highly standardized refeeding protocol group than in the historical control group (66.5 ±52.4 vs 147.3 ±55.7 grams/day; t-Test p=0.004; CI95%: 29.3-132.2). A carbohydrate rich diet clearly improved weight gain if high energy liquid nutrition was replaced by the diet according the patient’s own wishes. About 45% of our patients stated they were vegetarians at admission. However, we could not identify a vegetarian diet as a statistically significant negative prognostic factor for weight gain. Conclusion: The highly standardized refeeding protocol seems to be helpful in malnourished AN patients to improve weight gain without enhancing the risk of a refeeding syndrome. However, further studies with greater number of patients are needed to confirm the effectiveness of our standardized treatment protocol.

Purpose The endothetal Per-Arnt-Sim (PAS) domain protein 1 (EPAS1) gene which encodes hypoxia-inducible-factor-2 alpha (HIF2a) is a transcription factor that is involved in the response to hypoxia. EPAS1 has been found to have four (rs56721780, rs6756667, rs7589621, rs1868092) simple nucleotide polymorphisms (SNPs) associated with human disease.These SNPs were computationally examined with respect to changes in potential transcriptional factor binding sites (TFBS) and these changes were discussed in relation to disease and alterations in high altitude adaptation in humans. Methods The JASPAR CORE and ConSite databases were instrumental in identifying the TFBS. The Vector NTI Advance 11.5 computer program was employed in locating all theTFBS in theEPAS1 gene from 1.6 kb upstream of the transcriptional start site to 539 bps past the 3’UTR. The JASPAR CORE database was also involved in computing each nucleotide occurrence (%) within the TFBS. Results The EPAS1 SNPs in the promoter, intron two and the 3’UTR regions have previously been found to be significantly associated with disease and different levels of high-altitude hypoxia among native Tibetans. The SNP alleles were found to alter the DNA landscape for potential transcriptional factors (TFs) to attach resulting in changes in TFBS and thereby, alter which transcriptional factors potentially regulate the EPAS1 genesuch as for the glucocorticoid and mineralocorticoid nuclear receptor binding sites created by the rs7589621 rSNP EPAS1-G allele. These receptors regulate carbohydrate, protein and fat metabolism. Also the minor rs7589621 rSNP EPAS1-A creates a punitive TFBS for the FOXC TF which is an important regulator of cell viability and resistance to oxidative stress. These EPAS1 SNPs should be considered as regulatory (r) SNPs. Conclusion The alleles of each rSNP were found to generate unique TFBS resulting in potential changes in TF EPAS1 regulation. The punitive changes in TFBS created by the four rSNPs could very well influence the significant cline in allele frequencies seen in Tibetans with increasing altitude or the haplotype association with high altitude polycythemia in male Han Chinese. These regulatory changes were discussed with respect to changes in human health that result in disease and sickness.

An investigation into the proximate, mineral and antinutitional constitutents of natural cocoa powder (NCP), natural cocoa liquor (NCL) and alkalized cocoa powder (ACP) was carried out. Other parameters investigated were: energy values as contributed to the total metabolisable energy by protein, fat and carbohydrate and the energy percentages; calculated mineral quality parameters; mineral bioavailability as predicted by Ca: Phy, Phy:Zn and CaPhy/Zn molar ratios of the different cocoa products and mineral safety index (MSI) of some of the minerals of the samples. The data generated were subjected to statistical evaluation of chi-square (χ2). The three samples, NCP, NCL and ACP had proximate levels (g/100g) as: total ash, 3.73-10.8; moisture, 2.16-9.04; protein, 10.9-24.3; fat, 4.93-56.0; fibre, 1.03-17.3; carbohydrate, 20.5-48.9 and fatty acid, 3.95-44.8. For total energy contribution, results varied from, 1169-2656 kJ/100 g. In the minerals, the followings were higlhly concentrated: Na, K, Ca, Mg, Zn, Fe and P but low or not detected in Cu, Co and Mn. Virtually all the mineral quality parameters were poor as seen in these ratios: K/Na, Na/K, Ca/P and K/(Ca + Mg). The molar ratios of the samples were good enough to predict the bioavailability of the minerals. The mineral safety index (MSI) values showed that no mineral reached the toxic level in any of the samples. In the antinutritional constituents, ACP was highest in phytin phosphorus (Pp), phytin and Pp % of P; NCL was highest in oxalate and total phosphorus (P); tannin was highest in NCP. χ2 was significant in all proximate values (except ash, moisture and organic matter); all energy contributions, significant only in Mn (among the minerals); non was significant in the mineral quality parameters; only Ca: Phy was significant in the mineral molar ratios; no value was significant in the MSI and phytin was the only parameter significant among the antinutritional constituents.

Objective: Detailed reports in changes of eating habits especially in elderly subjects with successful weight loss and maintenance are virtually unknown. In this paper we have analyzed the eating habits of 104 obese patients (BMI 37.8±0.3 kg/m2, age range 65 and 84 years) who lost 11.5±0.3kg over an average follow-up period of 37.5±0.5 months. Design: Patients recorded food intake over a period of 12 days before and 12 days after changes of eating habits. Dietary counseling was based on food energy density (ED) with the aim to maintain food quantity as much as possible for adequate satiety in conjunction with a reduction of energy intake. Individual eating habits should be preserved as much as possible. Results: Average daily energy intake of solid food was reduced by 267kcal, food intake by 114g and ED by 0.10 kcal/g, respectively. Liquid calories were reduced by 79 kcal/d. Lower daily energy intake was the result of a reduction of medium and high ED food items compensated for by a greater intake of low ED food items. Changes of macronutrients comprised substantially lower carbohydrate and fat intake with minimal reduction of protein. From 28 different food groups 9 were reduced significantly (bread, butter, marmalade, cheese, meat products, fast food, fruit and chocolate) while 3 were increased (eggs, curds, ham). The relative contributions of the various food groups to daily energy intake remained fairly similar indicating that individual preferences were largely maintained. Conclusion: The data demonstrates that in elderly subjects with severe obesity an individual change of eating habits can lead to successful long-term weight loss with improvement of carbohydrate metabolism. This will contribute to increased mobility and to improved quality of life. This method which is based on the energy density of food items is a simple measure to reduce energy intake while ensuring long-term adherence.
