Healthier Food of Animal Origin and Prevention of Campylobacteriosis

Campylobacter species belong to the most important foodborne bacteria which cause gastroenteritis in humans in both developed and developing countries. Applied hygienic measures result only partially efficient, as demonstrated by the high number of reported cases in the human population. Alternative strategies to prevent the disease though a direct action at primary production level have been explored. Preliminary data showed that cattle and pigs fed with bamboo and olive by-products, respectively, were free from Campylobacter, suggesting potential sustainable prevention strategy. In addition, biochemical analysis showed high levels of unsaturated fatty acids in red meat and meat products, adequate for the application of health claims in line with EU food law.

Giving Food a Fiber Boost: Adding High Beta-Glucan Ingredient from Barley to Everyday Foods

Lack of dietary fiber contributes to many health issues, particularly chronic vascular diseases. Mixed linkage β-1.3 - 1.4 beta-glucan (beta-glucan, in this paper) is a confirmed beneficial ingredient for the human diet through reduction of cholesterol and the glycemic index. Barley contains the highest beta-glucan content of all the grains, and in this study, a percentage of flour from two high beta glucan lines was, each, added to an array of wheat-based food products to measure how it impacted total dietary fiber. Results showed that beta-glucan content was higher in all the products containing the added high beta-glucan flour, along with increased total dietary fiber content. Protein content in the food products is also increased with the higher protein in the barley flours added. Beta-glucan content in the barley-added products increased to 1.2% - 4.0% versus 0.2% - 0.5% in the pure wheat products, while the dietary fibers increased to 3.5% - 24.4% versus 2.1% - 9.1% in pure wheat product controls. This research provided experimental evidence that using a high beta-glucan barley ingredient in food can increase dietary fiber to benefit health.

Simultaneous Determination of Catechins and Caffeine in Green Tea-Based Beverages and Foods for Specified Health Uses

Catechins in green tea have various useful features including antioxidant activity and preventive effects on metabolic syndrome. Various beverages that are enriched with tea catechins are marketed as Foods for Specified Health Uses (FOSHU) in Japan. However, recent reports have indicated that excessive consumption of green tea extracts as a dietary supplement are associated with adverse health effects such as liver disorders. Various catechins and caffeine are constituents of FOSHU tea-based beverages. The amount of catechins in FOSHU products is displayed on labels as total catechin content, but the content of individual catechins are not provided. Although health hazards of FOSHU products have rarely been reported, precise information about the content and types of catechins in FOSHU products is needed to ensure safety. We used high-performance liquid chromatography with a photodiode array (HPLC/PDA) to simultaneously identify and quantify catechins and caffeine in green tea-based popular beverages and FOSHU beverages. This technique allowed simultaneous quantitation of five types of catechins and caffeine in green tea without complicated sample preparation. Epigallocatechin gallate (EGCG) and epigallocatechin EGC were the main catechins in various FOSHU beverages and the concentrations of almost all catechins were higher in FOSHU, than in popular green tea-based beverages. The concentrations of EGCG in green tea-based popular beverages and in FOSHU beverages were 5.4 - 7.3 and 10.2 - 41.9 mg/100mL, respectively, with the highest concentration being in a product named Healthya (approximately 147 mg/bottle). The simultaneous determination of compounds such as catechins and caffeine in FOSHU beverages can help to estimate beneficial and adverse effects to prevent deleterious effects on health and the excessive consumption of FOSHU beverages containing high concentrations of tea catechins should be avoided.

BIOLOGICAL EXPERIMENT AND CLINICAL TESTS ON MAMMOTROPIC ACTION OF MUYINGLE -A NEW TYPE OF HEALTHFOOD PREPARED FROM MARINE ORGANISMS

Muyingle is a new type of health food prepared from marine organisme. The mammotropic action ofMuyingte was investigated by studying its effect on mammary glands and pituitary glands of lactating miceand the survival rate of suckling mice. The results showed that the mammotropic action of Muyingle wasvery effective.The survival rates of suckling mice were 92.90% for the treated group and 0 for the controlgroup (p【0.01). The weights of mammary gland were 163±51.1mg/10g (weight of mouse)for the treatedgroup and 98.5±18.4 mg/10g for the control group (p【0.01). Histological examinations suggestal thatmammary glands from the treated group were at the secreting stages, while those from the control groupwere at the resting stages. Clinical tests also demonstrated that Muyingle was highly effective in promotinglactation and improving the quality of the puerpera’s milk. The efficiency was up to 86.7%.

Food Is Security: The Nexus of Health Security in Fragile and Failed States

Global food security is a major development challenge dictated by state stability, resilience to geopolitical and economic shocks and is linked to health security. Fragile and failed nation-states are at risk of extreme poverty and lead to war and conflict. Fragile states experience, corrupt financial regimes and are influenced by skewed global market systems and reduced equitable market access that decrease food and health security. This qualitative review describes the critical cross sections of food security, the influence of global market systems and state stability and institutions that form the nexus of global health security. We outline how the manipulation of free market systems and decreased state capacity not only decrease food and health security but also contribute to state fragility and failure. Improved public health policy mechanisms, decreased dependence on foreign financial structures and extractive mechanisms are crucial to improving food and health security at present, and to further increase state stability in the future.
