Assignment – Drinks: Evidence-Based Claims

HBS108 Assignment – Drinks: Evidence-based Claims ------------------------------------------------------------------------------------------------------------------------------------ 1. INTRODUCTION Drinks are an important and yet relatively under researched area of children's nutrition. The purpose of this report is to research on what the latest peer- reviewed evidence states about the health benefits of products such as Nutrient water, and to then to compare this literature to the health benefits of cow’s milk.

By examining a range of recently published peer-reviewed journal articles on the topic of advantages and disadvantages of drinks which are evidence based claims, this report is an examination and comparison between nutrient water type drinks and cow’s milk. The report then concludes with a recommendation on how to make a good nutritional choice in which is best for children to consume. 2i. ADVANTAGES OF CHILDREN REGULARLY CONSUMING “NUTRIENT WATER”-TYPE DRINKS

Consumers today want more from their beverages than merely good taste. In addition to nutrient water type drinks, energy drinks such as red bull, has continued to gain popularity among teenagers (Malinauskas et al. 2007, p. 2). Studies has shown that energy drinks provide the consumer with increased energy as shown in advertisements with the aid of caffeine by providing the desirable effects of increased alertness, improved memory, and enhanced mood (Oddy & O’Sullivan 2009, p. 4). Malinauskas et al. (2007, p. 6) states that through research, energy drink consumption is common among college students, particularly due to insufficient sleep, needing more energy in general, while studying for exams or working on major course projects and while driving an automobile for prolonged period. Guarana is an ingredient found in energy drinks, its functional claim is to increase energy, enhances physical performance, and promotes weight loss.

There is scientific evidence to support this claim, major component of guarana is caffeine and caffeine consumption has been associated with increased energy, enhancement of physical performance, and suppressed appetite (Scholey & Kennedy 2004, p. 321). 2ii. DISADVANTAGES OF CHILDREN REGULARLY CONSUMING “NUTRIENT WATER”-TYPE DRINKS Caffeine has been found to have detrimental health consequences.

At moderate intakes, caffeine can enhance endurance performance and concentration in adults, but when consumed in larger doses, caffeine can cause anxiety, agitation, sleeplessness, gastrointestinal problems, and arrhythmias (Oddy & O’Sullivan 2009, p. 64). Further, acute caffeine consumption reduces insulin sensitivity and increases mean arterial blood pressure. Central nervous system, cardiovascular, gastrointestinal, and renal dysfunction have been associated with chronic caffeine ingestion. According to Clauson et al. (2008, p. 6) research has also shown that the high glucose content of energy drinks and other flavored enhanced beverages plays a considerable role in weight gain, which can lead to serious health consequences such as diabetes. In addition, Clauson et al. explains that deaths, new-onset seizures, manic episodes have been linked to ingestion of large amounts of energy drinks. Based on findings, consumption of energy drinks nor nutrient enhanced drinks by children is not recommended. 3i. ADVANTAGES OF CHILDREN REGULARLY CONSUMING COW’S MILK According to Popkin et al. (2006, p. 33) many beneficial, and some detrimental, health effects have been attributed to the consumption of cow’s milk. Furthermore, Popkin et al. (2006, p. 533) states that for children and adolescents, milk is the current key source of vitamin D and calcium and is an excellent source of high-quality protein. Cow’s milk consumption has several benefits. Watt, Dykes and Sheiham (2000, p. 14) explains that an adequate intake of calcium is needed to ensure development and maintenance of skeletal strength. Bone disorders such as osteoporosis are an increasing health problem which can be prevented with daily intake of ample quantity of milk.

A recent study demonstrated that intake of milk in childhood and adolescence is associated with increased bone mass and density in adulthood (Kristensen et al. 2005, p. 1803). Pfeuffer and Schrezenmeir (2006, p. 113) states that recent observational studies confirm that the consumption of milk products can actually lower cholesterol levels, have reduced risk of protein malnutrition, fewer dental cavities, increased mineral content in children bones and fewer bone fractures. 3ii. DISADVANTAGES OF CHILDREN REGULARLY CONSUMING COW’S MILK According to Bell, Grochoski & Clarke (2006, p. 4) up until recently, the only reputed downside to consuming bovine milk and other dairy products were intolerances to lactose and allergies to milk protein. Furthermore, Bell, Grochoski & Clarke explains that despite its health bene? ts, the consumption of cow’s milk has come under scrutiny for its reported links to the risk of chronic diseases. According to Haug, Hostmark and Harstad ( 2007, p. 6) several studies has suggested that there is an association between milk consumption and blood pressure; as hypertension is inversely related to milk consumption in some epidemiological- and intervention studies.

It has been suggested that some milk peptides have antihypertensive effects, both by inhibiting angiotensin-converting enzyme, having opoid-like activities, antithrombotic properties and by binding minerals. Experiments demonstrate that high calcium content of milk can interfere with a child’s absorption of iron, another mineral that is crucial for development. To ensure a child is not iron deficient, it’s a good idea to avoid serving milk products and iron-rich foods in the same meal (Dewar 2009, p. 28). 4. CONCLUSION Drinks are an important and yet relatively under researched area of children's nutrition.

This report has identified the advantages and disadvantages of children who are of 9 to 12 years of age regularly consuming “nutrient water-type drinks and cow’s milk. The impact of regularly consuming cow’s milk as opposed to energy drinks in addition to “nutrient water-type drinks” is expected to have positive health benefits such as the prevention of osteoporosis, increased bone mass and density, lower cholesterol levels, reduced risk of protein malnutrition, fewer dental cavities, increased mineral content in children bones and fewer bone fractures. . RECOMMENDATION From the above mentioned peer-reviewed evidence-based discussion, we recommend that children and adolescents of 9 years of age and older group should consume 3 cups per day of fat-free or low-fat milk or equivalent milk products instead as compared with the nutrient enhanced water in addition to energy drinks. Based on findings, consumption of energy drinks nor nutrient enhanced drinks by children is not recommended as the ingredient found in those drinks might lead to adverse effects and possibly death in case of over consumption.

Patients with clinically relevant underlying medical conditions, including heart disease, should consult their physician before drinking energy drinks. The prevalence of childhood obesity is increasing, and switching from whole milk to low-fat or fat-free milk has been suggested as one way to reduce children’s intake of excess fat and calories. Diets rich in milk products can reduce the risk of low bone mass throughout the life cycle. The consumption of milk products is especially essential for children and adolescents who are building their peak bone mass and developing lifelong habits.

Although each of these food groups may have a different relationship with disease outcomes, the adequate consumption of all food groups contributes to overall health. 6.
