Abstract
Vitamin Bthree (niacin) is essential for all living cells and plays a central role in energy metabolism and oxidative phosphorylation. Vitamin Biii, a h2o-soluble vitamin, is nowadays in the form of nicotinic acid and nicotinamide, a monocarboxylic acid derivative of pyridine. While nicotinic acid is normally effective in lowering cholesterol levels, dissimilar nicotinic acid, nicotinamide is ineffective on lipids. Presence rates of nicotinic acid and nicotinamide, which are the available forms of vitamin B3, are dissimilar for each nutrient. Withal, the studies in the literature are generally based on the analysis of total corporeality of vitamin B3 in foods and the studies determining the profile of vitamin B3 in foods are limited. The aim of the study was to determine the vitamin B3 profiles of 10 kinds of fauna based food and 10 different plant based food samples. In this study, x kinds of animal based food samples consisting of veal (veal steak fillet), craven (breast), turkey meat (thigh), caprine animal meat (leg, abdomen), lamb (leg, back, arm), mutton (belly), bovine meat (loin) and ten different plant based nutrient samples namely; barley, rye, wheat (breadstuff), wheat (durum), oat, rice, dried pea, green lentil, red lentil and chickpea were studied past high performance liquid chromatography using post-column derivatization organization. The presence rates of nicotinic acid and nicotinamide were determined in the meat samples equally 30% and 70% and as 87% and 13% in the cereal and legume samples, respectively. Nicotinic acrid levels were found in low amounts in the meat samples. The amounts of nicotinic acid in the cereal and legume samples were significantly higher than the meat samples. Consequently, the plant based foods such as cereals and legumes, with a ratio of 87% nicotinic acid presence, standout as the all-time source of nicotinic acid and encouraging regular intake of those cereals and legumes containing rich nicotinic acid would remove nicotinic acrid deficiency in homo.

Background
Recently, there has been a growing involvement in vitamin Biii (niacin) past the emergence of NAD+ metabolism in health and disease and the apply of nicotinic acid as an important therapy for the treatment of hyperlipidemias [1]. Niacin is an important water-soluble vitamin and monocarboxylic acrid derivative of pyridine which plant in the nicotinic acid (C6H5NO2) form and nicotinamide (C6H6Due northtwoO) grade in foods [2]. The blanket term vitamin B3 is used for both forms. Nicotinic acid (also generally known every bit niacin) and nicotinamide (besides known every bit niacinamide) are similarly effective as a vitamin because they can be converted into each other within the organism [3].
Niacin, first isolated from rice bran in 1911, is readily metabolized and excreted vitamin with a recommended daily assart of 14–sixteen mg/day [4]. It was later recognised to take two distinct but chemically related components, nicotinic acid and nicotinamide.
Vitamin B3, in the course of the dinucleotides, is essential for all living cells and plays a central role in energy metabolism and oxidative phosphorylation and required for poly peptide, fat and sugar metabolism in the whole organism. Niacin perform important metabolic roles in living cells as a precursors of NAD+/NADH and NADP+/NADPH [5]. With this metabolic cofactor effect, it is actively involved in preventing many pathological processes. Its deficiency causes the disease called equally "pellagra" in man which is characterized by the rough or raw peel. Other bug include memory loss, vomiting and diarrhea. Niacin deficiency is also associated with an increased take a chance of cancer [6]. and has been shown to increment toxicity caused by reactive oxygen species [7].
B-complex vitamins that are not stored in the body, but should exist taken into torso daily [8]. A pocket-size amount of the niacin tin can be synthesized from the dietary amino acid tryptophan, but most of the daily requirement must be met by external sources of niacin [9]. The amount of niacin in the body is expressed in mg equally nicotinic acid (mg) + nicotinamide (mg) + i/60 tryptophan (mg). Additionally, riboflavin converts the amino acids into niacin [4,10,xi]. In add-on to being nutrients, nicotinamide and nicotinic acid are clinically applied pharmacological agents. Nicotinic acid is the oldest drug used to treat dyslipidemia. Very high intakes of niacin, many times larger than the conventionally accustomed vitamin levels, are used clinically: nicotinic acrid every bit a hypolipidaemic-hypocholesterolaemic agent [12], and nicotinamide in the treatment of schizophrenia [13] and other psychiatric disorders. Clinical studies take shown that nicotinic acrid therapy reduces the number of cardiac and the fatal center diseases [fourteen,15] and should be given in high doses for the lipid-lowering upshot. Nutrition is considered an of import factor for the development of dyslipidemia. [16]. Claret full cholesterol (TC) and low-density lipoprotein (LDL) correlate strongly with coronary centre disease. Hypercholesterolemia is an abnormally high amount of cholesterol in the blood. One of the main effect of nicotinic acid associated with reduced lipids (low density lipoproteins, fatty acids and cholesterol) [xvi,17].
Nicotinamide, get-go isolated from equus caballus erythrocytes in 1935, is the amide derivative of nicotinic acid [18]. While nicotinic acrid is commonly constructive in lowering cholesterol levels, unlike nicotinic acid, nicotinamide is ineffective on lipids.
Niacin is required to be taken with foods and found in various establish based and fauna based food sources. Skillful sources of niacin include yeast, meat, poultry, red fish (due east.m., tuna, salmon), cereals, legumes, and seeds. Milk, green leafy vegetables, coffee and tea besides provide some niacin [19]. In plants, specially mature cereal grains like corn and wheat, niacin may be leap to sugar molecules in the form of glycosides, which significantly subtract its bioavailability [20]. During the cooking of cereals, particularly in products that are slightly alkaline past the use of blistering soda, the availability of niacin increases [21].
In the literature, foods are associated with hypercholesterolemia in lowering cholesterol and it has been proven that foods with these ingredients to conduct a health claim indicating that they reduce the risk of cardiovascular disease [22–26]. The best mode to get the daily requirement of essential vitamins is to eat a counterbalanced diet that contains a variety of foods. Thus, loss or changes of nicotinic acid and nicotinamide acid in foods too should be taken under command during food procedure or storage weather. Knowing the profile of vitamin B3 is important in many ways such equally in the preparation of a complete food composition table, preparation of nutrition therapy, nutrition education, food security, condom and regulation, nutrient based dietary guidelines, labelling of food in the nutrient manufacture, nutritional survey and also for other research purposes.
Presence rates of nicotinic acid and nicotinamide, which are the bachelor forms of vitamin B3, are different for each food. Nevertheless, the studies in the literature are mostly based on the analysis of total corporeality of vitamin Bthree in foods [27–xxx] and the studies determining the contour of vitamin B3 in foods are limited [2,21,31–36]. Therefore, the aim of the written report was to investigate the presence and levels of vitamin B3 in some animal based and plant based foods for determining their vitamin Biii profiles in these foods which have been proven to have positive effects on health particularly on claret lipid level.
Materials and Methods
This written report has focused on the vitamin B3 profiles of some animal based foods and plant based foods. Postal service-cavalcade UV derivatization system by HPLC (high-performance liquid chromatography) was used to determine the presence and concentrations of nicotinic acid and nicotinamide in the 20 food samples consisting of ten meat samples and 10 cereal and legume samples. In this study, 10 kinds of brute based food samples consisting of veal (veal steak fillet), chicken (breast), turkey meat (thigh), goat meat (leg, belly), lamb (leg, back, arm), mutton (belly), bovine meat (loin) and 10 dissimilar plant based food samples namely; barley, rye, wheat (staff of life), wheat (durum), oat, rice, dried pea, green lentil, red lentil and chickpea were studied.
Reagents and materials
The vitamin standards (nicotinic acid and nicotinamide) and teflon tube "tubing" (length: 20 m diameter: 0.5 mm), used in this study, were obtained from Sigma-Aldrich (St. Louis, MO, U.s.a.). UVA lamp (twenty West, threescore cm) was used for post-column derivatization. Sodium hydroxide (NaOH), hydrochloric acid (HCl), hydrogen peroxide (HtwoO2), copper sulfate (CuSO4), trichloroacetic acid (C2HCl3O2) and potassium dihydrogen phosphate (KH2POfour) were obtained from Sigma (St. Louis, MO, USA). In this study, all other chemicals were used in loftier purity.
Samples of veal (veal steak fillet), chicken (chest), turkey meat (thigh), goat meat (leg, abdomen), lamb (leg, back, arm), mutton (belly), bovine meat (loin), barley, rye, wheat (staff of life), wheat (durum), oat, rice, dried pea, greenish lentil, red lentil and chickpea were purchased from local markets in Turkey and grounded in the laboratory.
Instrumentation
The profile of vitamin B3 was adamant past HPLC, consisting of Shimadzu Nexera-Ä° LC-2040C 3D pump with a Shimadzu RF-20A fluorescence detector (Shimadzu Corporation, Kyoto, Japan) according to the procedure described by Lahely et al. with some modifications [37]. The Zorbax eclipse X08-C18 column (5 μm, 4.vi × 150 mm) (Agilent, USA) was used and the flow rate was 1 mL/ min. The column oven temperature was maintained at 25 °C , the assay fourth dimension was forty min and the injection volume was twenty μL.
Standard training
Standard stock solution of nicotinic acid and nicotinamide (100 μg/mL) was prepared in 0.one N HCI solution. Each standard is freshly prepared daily. Working standards in v concentration levels were prepared from stock solution.
Sample preparation
Homogenized 1–x g of the samples (based on the estimated amount of niacin it may contain) were placed in 100 mL erlene, then 60 mL of 0.i Due north HCI was added and autoclaved at 121°C for 30 minutes. Then, the samples were taken from the autoclave and cooled down to room temperature, 2 mL of xx% tricycloacetic acrid (C2HCl3O2) solution was added to the solution, proteins were precipitated, the book was completed with 0.1 North HCI, filtered through filter newspaper. The terminal solution filtered through 0.45 μm filter into HPLC vials.
HPLC determination of nicotinic acid and nicotinamide profiles of vitamin B3
Post-column derivatization is required to decide the contour of vitamin B3. For post-column derivatization, a photo-chemical derivatization system was established in the laboratory. Detection methods described by Lahely et al. was used with some modifications [37]. The derivatization system was made by wrapping a teflon tubing with a length of 20 m and a diameter of 0.5 mm on a UV-A lamp lx cm long. The system was connected between the analytical column and the fluorescence detector. The mobile phase prepared daily and protected from low-cal. The mobile stage was prepared by mixing 500 mL of deionized water and 9.5 g of potassium dihydrogen phosphate (KH2PO4). So, 7.5 mL of hydrogen peroxide (H2O2) and ii mL of copper (II) sulfate solution (CuSO4) (0.12 copper (II) dissolved in 100 mL of deionized water) was added and the volume was completed with 1 L of deionized water. Finally, the mobile stage was filtered through a 0.22 μm filter. The fluorescence detector set up to excitation wavelength of 322 nm and emission wavelength of 380 nm, respectively. An Agilent eclipse X08-C18 cavalcade (5 μm, 4.6 × 150 mm, Agilant Technologies) was used and menstruation charge per unit of i mL/min. The injection volume was set at 20 μL, and separation was completed in forty min.
Results and Discussion
Method validation, quantification and quality command
Linearity was evaluated past analysing five different concentrations of standard solutions in triplicate.
The scale curve was obtained in a concentration range from 1 μg/mL to ten μg/mL and found to exist linear for nicotinic acid and nicotinamide with coefficient of decision greater than 0.996 every bit shown in Table one.

Limit of detection (LOD) and limit of quantification (LOQ) for nicotinic acid and nicotinamide were calculated from the scale line at the lowest concentration using the following equations: LOD = 3 × SD, LOQ = 10 × SD, (SD: standard difference). LOD and LOQ values have been shown in the Tabular array 1.
Dried pea sample was used for precision and accuracy assessment in the study. The precision report of the analytical method included repeatability and reproducibility tests. The repeatability was tested by analysing the aforementioned sample in ten replicate within the same day. The reproducibility was determined past analysing the aforementioned sample in sixteen replicates in three independent days. The relative standard deviation (RSD) values of repeatability are ii.0% and 2.0% respectively, RSD values of reproducibility are 2.08% and ii.04% respectively, for nicotinic acrid and nicotinamide equally shown in Tabular array 1.
The accurateness of the method was evaluated by analysing the Standard Reference Fabric 1849a, Baby/Adult Nutritional Formula (108±x mg/kg), demonstrating the validity of the assays. The recoveries for the dried pea sample was determined by spiking standard solution at concentration of 0.5 μg/mL. Recoveries were establish to be in the range of 96.four% and 104.2% for nicotinamide and nicotinic acid respectively, as shown in Table 1.
Blank samples of ultrapure h2o and reagents were too prepared using the same procedures as for the nutrient samples. In the decision of nicotinic acrid and nicotinamide no obvious interferences was observed from the bare chromatograms.
The quality procedures of belittling method were based on ISO/IEC 17025 requirements. A Standard Reference Material (SRM 1849a) Babe/Adult Nutritional Formula was provided from National Institute of Standards & Technology (Gaithersburg, Md, U.s.a.) and was go along in a like manner to the unknown samples.
For the quality of the research, nosotros participated in the FAPAS® test (2018), the proficiency examination for analysing breakfast cereal, which organized by FAPAS® (Nutrient Analysis Performance Assessment Scheme in UK). All analyses performed in triplicate, and the boilerplate value used. Our event was found in the acceptable range (−two ≤ Z score ≤ +2).

Vitamin B3 profiles of some brute based foods
The analytical method was successfully applied to determine the vitamin B3 profile of 10 meat samples; veal (veal steak fillet), craven (breast), turkey meat (thigh), goat meat (leg, abdomen), lamb (leg, back, arm), mutton (belly), bovine meat (loin), and the results are shown in Table 2.
Fig. 1 and 2 show typical chromatograms for standard solution and the goat meat (abdomen) sample, respectively.
The concentrations of nicotinic acid were found in the range of values between viii.five% and 49.6% in the meat samples while the concentrations of nicotinamide were institute betwixt 59% and 91.v%. Nicotinic acid form and nicotinamide form were found together in all meat samples.
Among the samples, the highest amount of nicotinic acid was constitute in chicken breast with 3.739 mg/100 g. Yet, since the chicken breast sample as well independent v.442 mg/100 yard nicotinamide, the concentration of nicotinic acid was listed in the third as a pct. In terms of the nicotinic acid contour, the highest amount of nicotinic acid was found in the chicken breast sample in a quantitative amount amongst the meat samples, but the highest percentage was the lamb arm sample. The lamb arm sample contains ii.112 mg/100 g nicotinic acid, simply too contains 2.143 mg/100 g nicotinamide so the presence of nicotinic acrid and nicotinamide in the lamb arm was found to be 49.six% and 50.4% respectively.
The lowest corporeality of nicotinic acid in the samples was the lamb back with 0.424 mg/100 chiliad and eight.v%. If nosotros list the nicotinic acid levels in the meat samples from high to low; chicken (breast), turkey meat (thigh), veal (veal steak fillet), lamb (leg), lamb (arm), mutton (belly), bovine meat (loin), goat meat (belly), caprine animal meat (leg) and lamb (back), respectively.
Another remarkable point is that the nicotinic acid levels in the meat samples differed in the meats belonging to the different regions of the animal. However, when comparison the amounts of nicotinic acid in the meat samples belonging to a region of the brute, it is likewise wrong to make a generalization. For instance, while in 3 different lamb meat samples, the highest corporeality of nicotinic acid (mg/100 k) was found in lamb leg, in goat belly meat the amount of nicotinic acid was higher than goat leg meat.
Vitamin B3 profiles of some found based foods
The belittling method was successfully practical to make up one's mind the vitamin B3 profile of ten cereal and legume samples; barley, rye, wheat (bread), wheat (durum), oat, rice, dried pea, greenish lentil, red lentil and chickpea, and the results are shown in Table iii.
In the cereals and legumes samples, the amounts of nicotinic acid were in the range of 30.4% to 100% and the nicotinamide concentrations were between 0% and 69.vi%. In 10 plant based food samples, the highest amount of nicotinic acrid containing sample was the durum wheat with 6.668 mg/100 g, while the lowest nicotinic acid containing sample was the oat with one.025 mg/100 g.
The presence and amounts of nicotinic acrid of the samples in mg per 100 one thousand from high to low, wheat (durum), wheat (breadstuff), barley, rye, green lentil, red lentil, rice, chickpea, dried pea and oat, respectively. When nosotros assess in terms of the profile, 7 of 10 samples (barley, rye, wheat (bread), wheat (durum), oat, rice, greenish lentil) did non contain nicotinamide and equally a upshot the concentration of nicotinic acid in these samples was 100%. In 70% of the cereal and legume samples was observed that but nicotinic acid grade was present (there were only nicotinic acrid form). While 70% of the cereal and legume samples were not in nicotinamide form, in iii samples (stale pea, red lentil, chickpea) nicotinic acid form and nicotinamide grade were seen together.
While the nicotinamide form was either absent or low level from nicotinic acrid grade throughout the samples, simply in the pea sample the corporeality of nicotinamide was more 2 times than the amount of nicotinic acid in quantity.
In consequent with the results of this study for the lamb meat total niacin content in the range of 4.3–5.8 mg/100 g, Williams reported in his study that 5.2 mg/100 g total niacin for the lamb meat in nutrient composition (per 100 g) of lean red meat list in the 'Nutritional limerick of red meat' study [thirty].
Co-ordinate to the Table 3, we can say that the cereals and legumes are the best sources of nicotinic acid. Although nicotinic acid form and nicotinamide form were present together in the all meat samples, in 70% of cereal and legume samples, only nicotinic acid form was nowadays.
In the cereal and legume samples, nicotinic acrid concentrations were found to be significantly college than the meat samples. Nicotinic acid concentrations were found in low amounts in the meat samples. Nicotinamide concentrations were much higher than nicotinic acid concentrations in all meat samples. The presence rates of nicotinic acid and nicotinamide were determined in the meat samples as 30% and 70% and every bit 87% and xiii% in the cereal and legume samples, respectively.
Every bit can exist clearly seen from Table 2 and 3, in terms of vitamin Biii profile, the profile in the meat samples appears as a combination of nicotinic acid and nicotinamide while the contour in the cereal and legume samples show the predominant characteristic of nicotinic acid with 100% nicotinic acrid class in 70% of the samples.
Nicotinic acid has been proven to have positive furnishings on blood lipid level. Clinically, high-dose nicotinic acrid leads to reduced lipidemias, reduced progression of coronary eye disease, and reduced mortality [xvi]. Dyslipidemia is the abnormal lipid metabolism which is regarded every bit a stiff predictor for the development of cardiovascular diseases (CVDs) and one of the well-nigh important run a risk factors for cardiovascular disease and diet is considered an important factor for the development of dyslipidemia [18].
Ahmad has been reported that incorporation of lentils in homo diets may assistance in protection and management of CVDs and related disorders co-ordinate to the results of the written report which investigates the effects of lentil on serum lipidemia and cardiovascular indexes in cholesterol-fed rats [38].
Niacin is a blazon of B vitamin and is also important for converting nutrient to energy. It is water-soluble, which means it is not stored in the body and leftover amounts of the vitamin get out the body through the urine. That means man demand a regular supply of vitamin B3 in their diet.
In the literature, at that place are studies based on total niacin content of foods. The results of this report were compared with the U.s.a. Section of Agronomics Nutrient Database and Turkish Nutrient Limerick Database. For instance, for the wheat (durum), total niacin content was found half dozen.668 mg/100 k in this study. In consistent with the findings of this study, according to the USDA, total niacin content of wheat (durum) is 6.738 mg/100 m in National Food Database [39]. In addition, according to Turkish Food Composition Database (TURCOMP), total niacin content of wheat (durum) 6.650 mg/100 m [xl].
In the literature, niacin sources are generally reported as meat, fish and poultry etc., but in particular their profiles should as well exist taken into business relationship. The results of the analysis showed that the total niacin content of meat samples was high merely, their profiles say many other things, the profiles showed a very valuable information as the levels of nicotinic acid were depression.
Jenkins et al., stated that the National Cholesterol Education Programme Developed Handling Panel Three (ATP III) and the American Heart Association accept been recommended the use of functional foods or foods loftier in components that reduce cholesterol every bit boosted options to enhance the effectiveness of cholesterol-lowering diets to increase the relevance of dietary advice for the main prevention of cardiovascular disease. These functional foods and components include mucilaginous fibers, soy poly peptide, found sterols, and nuts. Jenkins et al., accept been assessed the efficacy of these cholesterol-lowering components when combined in the same diet to determine whether predicted reductions in LDL cholesterol of 30% could be achieved by diet, in a series of metabolically controlled studies. They plant that, more than 30% of motivated participants who ate the dietary portfolio of cholesterol-lowering foods nether real-world weather condition have been able to lower LDL-cholesterol concentrations > xx%, which has not been significantly different from their response to a first-generation statin taken nether metabolically controlled conditions [25].
Chen et al., also summarized in their review that the findings of recent studies on the product, application, efficacy, and mechanisms of pop cholesterol-lowering nutraceuticals and functional foods. According to them; a nutritionally balanced nutrition that reduces saturated fat and cholesterol intake has traditionally been the first goal of dietary therapy in lowering plasma TC and recently nutraceuticals and functional foods have attracted much involvement as possible alternative therapies for lowering plasma TC, particularly for hypercholesterolemia patients, whose claret cholesterol level is marginally high (200–240 mg/dL) but non high enough to warrant the prescription of cholesterol-lowering medications [27].
Equally it is well known, the soluble fiber in foods reduces the concentration of elements required for cholesterol synthesis in the liver by inhibiting the assimilation of bile acids in the intestine. In addition, gamma tocopherol, which is found in fiber sources such as oats, barley, rice husks, reduces serum cholesterol by preventing cholesterol synthesis in the liver. Shamliyan et al. reported that the presence of five–x g soluble fiber in daily nutrition reduces the hazard of cardiovascular affliction and death and consuming foods rich in viscous soluble fiber reduces LDL cholesterol blood levels 10% to xv% with expected reduction in CVD events by 10% to 15% [26].
Mclntosh et al., studied the influence of two sources of dietary fiber (nonstarch polysaccharides, NSP) on blood lipids and glucose concentrations. 21 mildly hypercholesterolemic men aged 30–59 y have been provided with comparable barley and wheat foods for each of 4 week in a crossover-designed experiment. Barley contains β-glucan equally a source of soluble dietary fiber whereas wheat contains the largely insoluble cellulose and hemicellulose fiber. Consumption of barley relative to wheat foods has been associated with a significant fall in both plasma TC (vi%,p < 0.05) and in low-density-lipoprotein cholesterol (7%,p < 0.02) whereas triglyceride and glucose concentrations has not been inverse significantly. They have been concluded that barley dietary cobweb is more effective than wheat dietary cobweb at lowering blood cholesterol in hypercholesterolemic men [24].
Kirby et al. suggested that palatable and inexpensive high-fiber foods such as oat bran may have a role in the treatment of sure patients with hypercholesterolemia. They have been fed command and oat-bran diets in an alternate sequence to eight men with previously documented hypercholesterolemia to evaluate selected metabolic furnishings of establish fibers. They plant that serum TC concentrations were stable on control diets whereas a progressive reduction was observed in seven men on oat-bran diets. On oat-bran diets, average reductions in serum TC concentrations found thirteen% (p < 0.01, north = 8); plasma LDL cholesterol concentrations institute 14% lower (p < 0.05) while loftier-density lipoprotein cholesterol concentrations take not been inverse [23].
Health is vital for sustaining life and a healthy, adequate and balanced nutrition is essential for the preservation and maintenance of wellness. In order to have a good for you diet, everyone needs to know the nutritional composition of the foods they eat, as well as the corporeality of important vitamins and their profiles in the nutrients. In literature, no recent data is available about the profiles of vitamin Biii of foods such equally meat, cereal and legume that are eaten everyday by human. Moreover, numerous people oftentimes suffer from lack of nicotinic acid in their daily diets like people with high blood cholesterol levels. Nicotinic acid deficiency is one of the major dietary issues of people with hypercholesterolemia. People ordinarily think they meet the needs of nicotinic acid by consuming meat, fish and poultry etc.in their daily diet, considering of vitamin B3 is ofttimes referred to equally nicotinic acrid in the literature, which are known equally vitamin Bthree rich foods.
Conclusion
Niacin has many of import biological functions in humans and we demand to take more detailed and accurate information nearly it therefore, the determination of niacin profiles in biological samples is of import for evaluating nutritional conditions. This study was conducted in gild to determine the vitamin Biii profiles of 10 kinds of animal based nutrient and 10 different found based food samples by HPLC using post-column derivatization system. There is no available data and comprehensive study published in the literature regarding the vitamin Bthree profile in meats, cereals and legumes. This study will provide the vitamins B3 profile of some animal based foods and some plant based foods. However, this written report reported of vitamin Biii profiles in a express number of samples and hopefully, these new values will serve every bit a useful means to summate dietary intake of vitamin Biii in the general population. These data will also be useful in the grooming of a complete food composition table, preparation of diet therapy, food based dietary guidelines, nutrition education, food security, prophylactic and regulation, labelling of food in food manufacture, nutritional survey and besides for other inquiry aims.
