Food and Nutrition Sciences (FNS) , 2018, DOI: 10.4236/fns.2018.93020
Abstract: Nutritional fads in the health and fitness world are constantly changing. Each new craze has its believers and critics. For the consumer, “what to believe” becomes a topic filled with uncertainty. This paper presents a systematic approach to understanding what consumers believe about the health messaging of “raw beverages”. The paper presents both substantive results from US consumers, as well as demonstrates a general approach by which researchers can more deeply understand the consumer mind with respect to the specifics of health and wellness issues.

Abstract: Background: When usual calcium consumption patterns were analysed most people in the U.S. and Europe consume less than the recommended daily allowance. Supplements and fortified foods offer alternative and additional sources of calcium to traditional food. Calcium carbonate is the most common supplement but it is less soluble in water and, therefore, not suitable for enrichment of beverages. New organic calcium salts have a better solubility but less is known about their bioavailability. In the present study, we assessed the solubility and bioavailability of the new organic calcium salts, calcium lactate citrate and calcium lactate malate, in comparison to the traditional supplements, calcium carbonate and calcium gluconate. Design: Randomized, single-blind, four way cross-over study comparing single doses of 500 mg calcium in the form of four different calcium-salts. Subjects were advised to consume 25 µg vitamin D3 daily two weeks prior to the start of the study and during the whole study period. Subjects: 20 healthy young men, Methods: Blood samples were drawn immediately before and 2, 4, 6, 8, 12 and 24 h after ingestion of the calcium preparation. Concentration of total calcium and intact parathyroid hormone were measured in the serum. Urine was collected at baseline and during the intervals 0-3, 3-6, 9-15 and 15-24 h and excretion of calcium, sodium and creatinine was examined. Results: The tested new salts were easily water soluble, significantly better than calcium gluconate. Calcium carbonate is almost insoluble. The bioavailability of the four different calcium salts was found to be almost identical. The maximum total serum calcium increased by 7.6 % two hours after ingestion calcium lactate citrate, by 7.4 % after calcium lactate malate, by 5.5 % after calcium carbonate, and by 5.8 % after calcium gluconate. Intact parathyroid hormone concentration showed the expected depression for calcium lactate citrate, calcium lactate malate and calcium carbonate, whereas the serum level was significantly higher after ingestion of calcium gluconate. Conclusion: Given an almost equivalent bioavailability of the four tested calcium salts, we conclude that the new salts calcium lactate citrate and calcium lactate malate are well suited for fortification of beverages and thus to increase the average daily calcium intake.

Open Journal of Psychiatry (OJPsych) , 2012, DOI: 10.4236/ojpsych.2012.24042
Abstract: Affordability and availability of alcohol are factors that have been associated with alcohol dependence. Ethanol content in the alcoholic beverages is an important determinant in alcohol dependence. Quality control of alcoholic beverages available in the market is important in safeguarding the health of alcohol consumers. Few studies in Kenya have determined the chemical composition of alcohol used by the study participants. Objective: To determine the chemical composition of alcoholic beverages used by a group of alcohol dependent study participants. Design: The study was a clinical trial with pre and post measurements. Method: The CIDI and WHO-ASSIST were administered to 188 alcohol-dependent persons at intake and after six months. A researcher-designed socio demographic questionnaire was also administered at intake. Alcohol beverages were randomly collected from the location of the study area and their chemical composition analyzed using gas chromatography. Results: The mean AUDIT score of the participant was 28.6 for male and 26.6 for females. Three of the alcohol samples collected was illicit brews collected while 11 were licit. Four out of the eleven licit brews had ethanol levels that did not complied with the set government standards. Conclusion: Illicit brews with high ethanol content are available in the Kenyan market, while some of the manufacturers of the licit brew do not comply with government set content recommendations.

Abstract: The consumption of beverages and processed foods, mainly soft drinks, has been incorporated into the usual diet of children, adolescents and adults frequently in recent years. The present study aimed to study the effects of carbonated drinks on Wistar rats, based on the macroscopic and histological morphology of the esophagus. Fifteen Wistar rats were divided into three groups: control group; group fed with ration and cola-type refrigerant ad libitum and group fed with ration and gas industrialized water ad libitum, for a trial period of 90 days. For histopathology and morphology, the esophagus was removed, prepared in slides and stained with hematoxylineosin. Images of the sections were captured for analysis and classification of the inflammatory infiltrate. For morphometry, ten grid fields of 100 points were evaluated in the 40x eyepiece, totaling 3000 points per animal. The results demonstrate that the refrigerant treatment induced the following structural changes in the rats: significant reduction of weight in relation to the control group; inflammatory infiltrate predominantly diffuse mild to moderate and tissue edema. The rats treated with carbonated water had similar results to the control, besides signs of healing and tissue repair.

Abstract: Knowledge of the chemical composition of Mozambican spirits is extremely important because the studies of potentially toxic compounds have been a determinant factor in quality control. The objectives of this work were to analyze and physicochemically characterize distilled sugarcane spirits and other raw materials from Mozambique on the basis of the standards established by the Brazilian Ministry of Agriculture, Livestock and Food Supply (MAPA). The samples came from five provinces of southern and central Mozambique, provided by the owners of the stills in the localities of Manhica, Xinavane, Chókwe, Massinga, Mafambisse, Beira and Chimoio. The four samples from Brazil were randomly collected from different regions of Minas Gerais. The parameters analyzed were ethanol, methanol, higher alcohols, aldehydes, volatile acidity, furfural, esters and copper concentrations. The Mozambican spirits produced from different raw materials, compared to Brazilian spirits, contained very variable concentrations of the components analyzed. Mozambican spirits are of much lower quality than Brazilian beverages and are not suitable for consumption.
