Abstract

Purpose

The debate on the metabolic effects of high fructose corn syrup (HFCS) continues. The deterioration of endoplasmic reticulum (ER) homeostasis is called ER stress. Glucose-regulated protein-78 (GRP-78) and X-box binding protein-1 (XBP-1) are key markers of ER stress and the therapeutic targets of diseases. Sterol regulatory element binding protein-1c (SREBP-1c) is the most important transcription factor that regulates the expression of enzymes for fatty acid synthesis. The purpose of this paper is to research the effects of L-carnitine and trans-chalcone on ER stress and oxidative stress parameters, and to explore the therapeutic potential of L-carnitine and trans-chalcone molecules.

Design/methodology/approach

Forty male wistar albino rats randomly selected were divided into five groups. All groups are fed with standard chow (ad libitum). While Group I was fed with drinking water, Group II, III, IV and V were fed with water containing 15% HFCS. L-carnitine was given to Group IV and trans-chalcone to Group V, and both were dissolved with DMSO and given intraperitoneally. Group III was not given anything additional.

Findings

While the amount of water consumption of HFCS-fed rats has increased, the amount of feed consumption has decreased. The weights of rats in Group II and Group III have increased significantly compared to Group I (p = 0.001, p = 0.001 respectively). In Group III, GRP78, XBP-1; malondialdehyde level (p < 0.001, p = 0.001, p = 0.041); total cholesterol, triglyceride, LDL levels (p = 0.001, p < 0.001, p = 0.009, p = 0.001, respectively) have increased significantly.

Originality/value

To the best of the authors’ knowledge, this study is the first report to show that excessive HFCS consumption causes oxidative stress and ER stress. The antioxidant and antiobesity properties of trans chalcone have been demonstrated. Extensive experimental and clinical studies should be conducted.

Abstract

The entrance of economics into the literature on obesity and diabetes has been instrumental in showing how people respond to incentives when maximizing their health. In this paper some of the roles that prices and policies have played in the surging obesity and diabetes rates across the world are addressed. The paper focuses on the possible role that prices of foods with high glycemic indexes play in determining blood sugar levels, and addresses the recent concern with high fructose corn syrup and genetically modified goods across the world. The possible links and implications suggest that future research in the area is urgently needed.

Abstract

A small firm, like Key Pharmaceuticals, pioneers niche businesses by developing novel ways of delivering medicine to a patient's bloodstream—for example, nitroglycerine absorbed through adhesive pads on cardiac patients' chests. Key Pharmaceuticals is viewed as an ally by the large pharmaceutical firms as long as it stays out of their drug discovery businesses. • A small company refuses to abandon loyal customers when other firms stop producing products that face declining demand. For example, Beaunit makes cupramonium‐process rayon, which is needed by the small casket‐velvets market; enterprising electronic component distributors buy out inventories of obsolete vacuum tubes to supply a few good customers who don't want to retire their equipment before it wears out. Neither firm is challenged in its market niche because competitors don't consider the rewards worth the effort. • The “new company on the block” demonstrates its credibility by investing aggressively in a pioneering idea—as Archer‐Daniels‐Midland did with high fructose corn syrup in the maturing corn wet milling industry. The gamble succeeds because its larger rivals ignore its activities—perhaps because they don't consider the pioneer a threat; or because they believe that they can easily copy the pioneer's successes; or they're busy with more important battles in other markets.

Abstract

Purpose

This study aims to evaluate the use of vacuum impregnation (VI) for developing vitamin E fortified fresh‐cut apples (Fuji).

Design/methodology/approach

A 20 per cent high fructose corn syrup (HFCS) or edible coating materials of 1 per cent hydroxypropyl methylcellulose (HPMC) and 1 per cent calcium caseinate (CC) were used to make VI solutions, and 0.4 per cent α‐tocopherol acetate, 7.5 per cent gluconal cal\tf="Pi3" \char"31 (GC) and 0.04 per cent zinc lactate (ZL) were incorporated into the VI solutions. Vitamin E content, color, and selected physicochemical properties of fortified fresh‐cut apples were analyzed.

Findings

Results showed that VI treatment with 20 per cent HFCS solution containing 0.4 per cent α‐tocopherol acetate increased vitamin E content up to 21.8 mg in 100 g of fresh‐cut apples, while 12.0 mg and 20.2 mg vitamin E were achieved when using 1 per cent HPMC or 1 per cent CC as VI solutions, respectively. Calcium and zinc content were also increased to 146.6 mg and 1.7 mg in 100 g of apples, respectively, when adding 7.5 per cent GC and 0.04 per cent ZL along with the vitamin E into the VI solutions. Use of HFCS, HPMC and CC as VI solutions resulted in different effects on the physiochemical properties of fresh‐cut apples. While HFCS is promising for vitamin E fortification and retention of natural apple color, HPMC and CC can be used to achieve similar vitamin E fortification with the least impact on the soluble solids and moisture contents of apples.

Originality/value

The study demonstrates that there is great potential for developing high quality, vitamin E and minerals fortified fresh‐cut apples using vacuum impregnation technology, thus further enhancing the health benefit of the apples.

Abstract

Purpose

This study aims to examine whether Globularia alypum (Ga) lyophilized aqueous leaves extract treatment improves cardiometabolic syndromes such as hyperglycemia, lipid profiles and oxidative damage resulting from a high-fructose diet induced in hypertriglyceridemic rats.

Design/methodology/approach

A total of 24 male Wistar rats weighing 80 ± 5 g were first randomly divided into 2 groups. A total of 12 control rats (C) were fed a standard-diet (St-D) and 12 high fructose (HF) rats were fed a high-fructose diet (HF-D) containing St-D in which cornstarch was substituted by fructose (61.4%). After 15 weeks of feeding, body weight (BW) was about 320 ± 20 g and hypertriglyceridemia was noted in HF vs C group (2.69 ± 0.49 mmol/L) vs (1.25 ± 0.33 mmol/L). Each group of rats was then divided into two equal groups (n = 6) and fed during four weeks either a St-D or HF-D, treated or not with 1% of Ga extract (C-Ga) and (HF-Ga). After 28 days, fasting rats were anesthetized and blood and tissues were removed to measure biochemical parameters.

Findings

The results showed no significant differences in BW and insulinemia between all groups. Ga extract supplementation reduced glycemia (−36%), glycosylated hemoglobin (−37%), Homeostasis Model of Assessment-Insulin Resistance index (−34%) and triacylglycerol’s contents in plasma (−33%), very low density lipoproteins–low density lipoproteins (VLDL-LDL) (−48%), liver (−52%) and aorta (−39%); total cholesterol concentrations in aorta was 3.7-fold lower in HF-Ga vs HF group. Ga treatment reduced lipid peroxidation in plasma, VLDL-LDL, red blood cells (RBC), liver, muscle and kidney by improving superoxide dismutase (SOD) activity and glutathione peroxidase (GPx) in RBC and catalase (CAT) activity in kidney (p < 0.05). Moreover, Ga ameliorates glutathione (GSH) production in RBC (+41%) and kidney tissues (+35%).

Originality/value

Ga extract ameliorated cardiometabolic syndrome by its hypotriglyceridemic effect and prevented development of insulin resistance. It reduces lipid peroxidation by enhancing non-enzymatic (GSH) and enzymatic (SOD, GPx and CAT) antioxidant defense systems in high-fructose hypertriglyceridemic rats. Therefore, supplementation of Ga leaves extract as an adjuvant could be used for the treatment of hypertriglyceridemia and the prevention and/or the management of cardio-metabolic adverse effects.

Abstract

Purpose

Low fruit and vegetable intake is associated with heart disease, some cancers, and other major causes of death. Product pricing influences food purchases and economic declines have affected food budgets; therefore, this study examined the nutritional quality of advertised meal deals and buy-one-get-one free (BOGO) offers at three major grocery store chains over ten weeks. The paper aims to discuss these issues.

Design/methodology/approach

USDA's SuperTracker and Diet Analysis Plus were used for nutritional analyses of advertised offers over a ten-week time period in Fall 2011.

Findings

Meal deal – ten-week averages per person: prices ranged from $1.25 to $5.00. Evaluation of MyPlate categories revealed the following percentage breakdown: empty calories – 57 percent, grains – 21 percent, protein – 12 percent, dairy – 8 percent, vegetables – 2 percent, and fruit – 0 percent. BOGO – ten-week averages: when examining MyPlate categories, nutritional quality was similar to meal deals in that few products were from the vegetable (12 percent) fruit (4 percent), and dairy (3 percent) groups.

Originality/value

Research is sparse regarding nutritional quality of advertised sales at grocery stories.

Abstract

Since 1981, the U.S. federal government has operated a price support program to help sugar beet and sugar cane producers and processors. This complex program works through a combination of loans, import quotas, and duties. As a result, sugar prices in the United States are significantly higher than world prices. For example, in December 2001, U.S. consumers paid 22.9 cents per pound, while the world price was just 9 cents per pound. The General Accounting Office estimates that the total cost to consumers is $1.9 billion a year. Uses a simple demand-and-supply framework with real-world data to assess the economic and political consequences of the U.S. sugar program.

To illustrate welfare concepts such as consumer surplus, producer surplus, and dead-weight loss in a concrete, real-world market context.

Abstract

The long controversy that has waxed furiously around the implementation of the EEC Directives on the inspection of poultry meat and hygiene standards to be observed in poultry slaughterhouses, cutting‐up premises, &c, appears to be resolved at last. (The Prayer lodged against the Regulations when they were formally laid before Parliament just before the summer recess, which meant they would have to be debated when the House reassembled, could have resulted in some delay to the early operative dates, but little chance of the main proposals being changed.) The controversy began as soon as the EEC draft directive was published and has continued from the Directive of 1971 with 1975 amendments. There has been long and painstaking study of problems by the Ministry with all interested parties; enforcement was not the least of these. The expansion and growth of the poultry meat industry in the past decade has been tremendous and the constitution of what is virtually a new service, within the framework of general food inspection, was inevitable. None will question the need for efficient inspection or improved and higher standards of hygiene, but the extent of the organization in the first and the enormous cost of structural and other alterations to premises in the second, were seen as formidable tasks, and costly. The execution and enforcement of the new Regulations is assigned to local authorities (District, Metropolitan and London Borough Councils), who are empowered to make charges for inspection, licences, etc., to recoup the full costs of administration. The Government had previously promised that the cost of this new service, which when fully operative, will be significant, would not fall upon the already over‐burdened economies of local authorities. The figure of a penny per bird is given; in those areas with very large poultry processing plants, with annual outputs counted in millions of birds, this levy should adequately cover costs of enforcing the Regulations, but there are many areas with only one of a few small concerns with annual killings of perhaps no more than 200,000 birds—this much we know from perusing annual health reports received at the offices of this Journal—and the returns from charges will certainly be inadequate to cover the cost of extra staff. The Regulations require the appointment of “official veterinary surgeons” and “poultry meat inspectors”, both new to local government.

Abstract

Examines the impact of the sugar tariff‐rate import quota programme on the United States economy. Uses a computable general equilibrium model composed of 14 producing sectors, 14 consuming sectors, six household categories classified by fincome, and a government. Examines the effects of abolishing the tariff‐rate import quota on sugar prices and quantities. Suggests that a complete elimination of the sugar programme would result in lower output by all producing sectors (by about $2.85 billion) but, for all producing sectors besides the agriculture programme crops, crude oil, and petroleum refining sectors, output would actually increase (by about $2.98 billion). There would also be an increase in the consumption of goods and services (by about $197 million), and an increase in welfare (by about $121 million). The government would realize a reduction in revenue of about $15 million. When subjected to a sensitivity analysis, the study′s results are reasonably robust with regard to the assumption of the value of the own‐price elasticity of demand for sugar – i.e., while the model′s equilibrium values do vary in response to different assumptions of the values of this elasticity, the fluctuations are not so enormous as to suggest that the model is unrealistically sensitive to these parameters.
