TL;DR: In this paper, the levels of some nutrients and antinutrients of sweet potatoes (Ipomoea batatas), leaves were determined using standard analytical methods, and the results reveal that the leaves contain an appreciable amount of nutrients, vitamins and mineral elements and low levels of toxicants and should be included in diets to supplement our daily allowance needed by the body.
Abstract: 2 Abstract: Levels of some nutrients and antinutrients of sweet potatoes (Ipomoea batatas), leaves were determined using standard analytical methods. Crude protein, crude fat, crude fibre, ash, carbohydrate, moisture contents and calorific values were 24.85%, 4.90%, 7.20%, 11.10%, 51.95%, 82.21% and 351.30 kcal respectively. The vitamin composition was found to be at the levels of 0.672 mg/100g for vitamin A and 15.20 mg/100g for vitamin C. The elemental analysis of the leaves in mg/100g Dry matter (DM) indicated that the leaves contained appreciable levels of zinc (0.08), potassium (4.05), sodium (4.23), manganese (4.64), calcium (28.44), magnesium (340.00) and iron (16.00). The antinutrient composition for phytic acid, cyanide, tannins and total oxalate were 1.44 ± 0.01, 30.24 ± 0.02, 0.21 ± 0.02 and 308.00 ± 1.04 mg/100g respectively. These results reveal that the leaves contain an appreciable amount of nutrients, vitamins and mineral elements and low levels of toxicants and should be included in diets to supplement our daily allowance needed by the body.

TL;DR: In this article, the unripe pulp of Carica papaya was screened to test for the presence of certain phytochemicals such as saponins and cardenolides.
Abstract: Unripe pulp of Carica papaya was screened to test for the presence of certain phytochemicals. Chemical composition of the pulp were determined. Phytochemical screening of mature unripe pulp of Carica papaya (dry weight) showed the presence of saponins and cardenolides while chemical analysis revealed the presence of potassium (223.0mg/100g) as well as sodium, calcium, iron, phosphorus, zinc, copper, magnesium and manganese in considerable quantities. Proximate analysis of the pulp showed that it contained starch (43.28%), sugars (15.15%), crude protein (13.63%), crude fat (1.29%), moisture (10.65%) and fibre (1.88%). All these results indicate that the pulp of mature unripe Carica papaya contains nutrients and mineral elements that may be useful in nutrition. The presence of some phytochemicals like saponins and cardenolides explained the astringent action of the plant encountered in the numerous therapeutic uses.

TL;DR: This paper attempts to review the consumption, process, chemical and nutritional composition and the health benefits of kefir.
Abstract: Kefir is fermented milk only made from kefir grains and kefir cultures as no other milk culture forms. Kefir grains are the mixture of beneficial bacteria and yeast with a polysaccharide matrix. During fermentation lactic acid, CO , ethyl alcohol and aromatic compounds that make its unique organoleptic 2 properties are occurred. Kefir is used for the treatment or control of several diseases for many years in Russia. It is begun to consume in some areas of the world, southwestern Asia, eastern and northern Europe, North America and Japan for its nutritional and therapeutic aspects. This paper attempts to review the consumption, process, chemical and nutritional composition and the health benefits of kefir.

TL;DR: In this article, the authors examined the socioeconomic characteristics and determinants of the food security status of rural farming households in Kwara State of Nigeria and concluded that the design of food security strategies should be multi-dimensional such that would focus on and address the identified determinants in order to achieve the target set by the Millennium Development Goals.
Abstract: In recent times, the global focus has been on food security and poverty alleviation. This is in response to increasing food insecurity and poverty in the world. The incidences of food insecurity and poverty are particularly devastating in the developing countries and a lot of resources are being channelled towards programmes aimed at eradicating food insecurity and poverty by various international organizations and government of the developing nations. In terms of food insecurity, 852 million people worldwide are still chronically undernourished. In Africa, an estimated 200 million or 27.4% of the people on the continent are undernourished. This figure is expected to increase to 30% by 2010. In Nigeria, over 40% of the estimated population of 133 million people are food insecure. To achieve the Millennium Development Goals of halving the proportion of hungry people by 2015, it was projected that 22 million people must achieve food security every year. In consonance of the above, this study examined the socio-economic characteristics and determinants of the food security status of rural farming households in Kwara State of Nigeria. The study utilized a three-stage random sampling technique to obtain a sample of 94 farm households and a cross sectional data in year 2005. Descriptive analysis was carried out to describe the socio-economic characteristics of the households. Econometric tools were used to determine factors affecting the food security status of household. Using the recommended calorie required approach; the study revealed that 36% and 64% of the households were food secure and food insecure respectively. The Shortfall/Surplus index showed that the food secure households exceeded the recommended calorie intake by 42%, while the food insecure households fell short of the recommended calorie intake by 38%. A logit regression model made up of eight regressors was specified. Household income, household size, educational status of household’s head and quantity of food obtained from own production were found to determine the food security status of farming households in the study area. It is concluded that the design of food security strategies should be multi-dimensional such that would focus on and address the identified determinants in order to achieve the target set by the Millennium Development Goals.

TL;DR: Current scientific evidence supports the role of probiotic LAB in mediating many positive health effects and interest in these compounds has grown substantially due to their potential usefulness as natural substitute for chemical food preservatives in the production of foods with enhanced shelf life and / or safety.
Abstract: Fermentation of various food stuffs by lactic acid bacteria (LAB) is one of the oldest forms of biopreservation practiced by mankind . Bacterial antagonism has been recognized for over a century but in recent years this phenomenon has received more scientific attention , particularly in the use of various strains of lactic acid bacteria One important attribute of many LAB is their ability to produce antimicrobial compounds called bacteriocins. In recent years interest in these compounds has grown substantially due to their potential usefulness as natural substitute for chemical food preservatives in the production of foods with enhanced shelf life and / or safety. There is growing consumer awareness of the link between diet and health. Recent scientific evidence supports the role of probiotic LAB in mediating many positive health effects.Traditional probiotic dairy strains of lactic acid bacteria have a long history of safe use and most strains are considered commensal microorganisms with no pathogenic potential.
