The aim of this thesis was to investigate whether providing foods enriched with ß•glucan would be a feasible strategy for improving consumers’ dietary fibre intake regarding the sensory properties and consumer acceptance of these foods. ß•glucan is a good option for fibre enrichment of foods because of its proven capability to reduce elevated blood cholesterol levels and to balance blood glucose and insulin response after meals. The study showed that dietary fibre had a positive image among Finnish respondents and it was considered important for health. Beverages and soups with added ß•glucan were acceptable regarding their sensory characteristics, thus being feasible carrier products for ß•glucan and providing a possible non­traditional source of dietary fibre. Liking for the products with added ß•glucan was the most important factor affecting the willingness to use them, indicating that the sensory quality of products with added dietary fibre with health benefits has to be acceptable, only then consumers are willing to buy them.

Materials and Methods: In this paper, the mechanism of action of a mix in capsules of 0.6 g of β-Glucan (Active hexose correlated compound “AHCC” and β-Glucan 1,3-1,6) on the neoplastic cell line transcriptome has been explored. The cellular models used were Caco2 and LS174T cell lines. Transcriptome analysis was performed by RNA expression analysis of transcripts of both single and multiple samples. The analysis was completed with the aid of information technology. Results: ROS (Reactive Oxygen Species) decrease following glucans treatment (Figure 1) com- bined with a marked improvement in the Redox control of SOD1 (Superoxide Dismutase 1) (Figure 2), which is pre-sent in the cytosol of all eukaryotic cells with copper and zinc (Cu-Zn-SOD). Follow- ing glucan mix treatment, COX-2 (cyclooxygenase-2) expression levels showed a marked reduction (Figure 3A).

  • Carbohydrate Counting

    Carbohydrate Counting

    Carbohydrate Counting What is Carbohydrate Counting? Carbohydrate counting is a meal-planning tool that many people use to manage their blood sugar. Carbohydrate counting, or ‘carb counting’, is done by tracking the amount of carbohydrates eaten at meals and snacks. Carbohydrates are a type of nutrient found in starchy and sweet foods. When starchy or sweet foods are eaten, the body breaks the carbohydrates in the foods down into glucose. This glucose is released into the blood. Another name for glucose in the blood is blood sugar. There are four steps in carbohydrate Foods with carbohydrates: counting: • Soda pop, juice, Tang, Kool-Aid, and other sweet drinks • Starchy vegetables like potatoes, corn, squash, beans and peas 1. Timing • Rice, noodles, oatmeal, cereals, breads, crackers 2. Amount • Milk and yogurt 3. Balance • Beans 4. Monitoring • Chips, cookies, cakes, ice cream Step 1: Timing • Fruit and fruit juice A moderate amount of carbohydrate foods gets broken down into a moderate In diabetes meal planning, one choice of carbohydrates has about 15 grams of amount of blood sugar. carbohydrates.

    Health Claims in Food Advertising and Labeling

    Chapter 11 Health Claims in Food Advertising and Labeling Disseminating Nutrition Information to Consumers Alan D. Mathios and Pauline Ippolito The question of how best to get evolving scientific evidence linking diet and disease to consumers has been much debated in policy cir- cles. At the core of this debate are widely varying presumptions about how effective food manufacturers are in reaching consumers com- pared with, or in addition to, government and other information sources, and about the best approaches for controlling misleading or deceptive claims. This chapter evaluates whether policy changes that took place in the mid-1980s, and allowed food manufacturers to explicitly link diet to disease risks in advertising and labeling, appear to have improved consumers food choices (the information hypothesis), or as many critics fear, to have confused consumers suf- ficiently to slow improvements in diet that would otherwise occur (the consumer confusion hypothesis). Introduction In the last 30 years, scientific understanding of the role of diet in chronic disease risks has improved significantly. In the United States, diet is now believed to be linked substantially to 4 of the top 10 causes of death, and diet-disease research is continuing at a rapid Mathios is Associate Professor, Department of Policy Analysis and Management, Cornell University; and Ippolito is Associate Director for Special Projects, Bureau of Economics, Federal Trade Commission.

    fermentation Article Development of Probiotic Almond Beverage Using Lacticaseibacillus rhamnosus GR-1 Fortified with Short-Chain and Long-Chain Inulin Fibre Lauren Muncey and Sharareh Hekmat * School of Food and Nutritional Sciences, Brescia University College, Western University, London, ON N6G 1H2, Canada; [email protected] * Correspondence: [email protected]; Tel.: +519-432-8353 (ext. 28227) Abstract: Plant-based beverages are growing in popularity due to the rise of vegetarianism and other health trends. A probiotic almond beverage that combines the properties of almonds, inulin, and Lacticaseibacillus rhamnosus GR-1 may meet the demand for a non-dairy health-promoting food. The purpose of this study was to investigate the viability of L. rhamnosus GR-1 and pH in five fermented almond beverage samples, supplemented with either 2% or 5% (w/v) short-chain or long-chain inulin over 9 h of fermentation and 30 days of refrigerated storage. All almond beverage samples achieved a mean viable count of at least 107 CFU/mL during 9h of fermentation and 30 days of refrigerated storage. The probiotic almond beverage supplemented with 2% (w/v) short-chain inulin had a significantly higher mean microbial count (p = 0.048) and lower pH (p < 0.001) throughout fermentation, while the control and the long-chain inulin treatments had the lowest viable counts and acidity, respectively. This study shows that the addition of short-chain and long-chain inulin had Citation: Muncey, L.; Hekmat, S. no adverse effects on the viability of L. rhamnosus GR-1. Therefore, the probiotic almond beverage Development of Probiotic Almond has the potential to be a valid alternative to dairy-based probiotic products.

Supported by P&G BloodSugar-RecommendedWithCaution.indd 1 6/26/2017 4:34:17 PM Source Beta-glucan is a soluble fiber derived from the cell walls of certain algae, bacteria, fungi, yeast, and plants. Yeast-derived beta-glucan is more palatable and easier to incorporate into food products. Oat beta-glucan is soluble in water and may have a higher therapeutic benefit with its increased viscosity. Indications/Population Lower post-prandial glucose and insulin levels Lower HbA1c Patients with type 2 diabetes and prediabetes Patients with metabolic syndrome Mechanism of Action The mechanism of glucose lowering by beta-glucan is unclear.
