However, lots of peer reviewed articles in dietetics are aimed to establish and clarify the dietary requirements due to which people can maintain a healthy life and receive nutrients in reasonable quantity and sufficient quality. It is crucial to have an adequate mineral intake at any age in order to not hurdle normal organism’s functioning and to prevent diseases. There are many publications sometimes styled as a fast food persuasive essay that argue a vast abundance of essential minerals, such as Mn, Ca, Cr, Cu, Fe, Zn, Se and Mg in fast foods, although they often skip or at best mention in passing the bioavailability of these minerals.
Together with a health concern that is deepening, there appear many scientific articles and one can meet a good sample of a book report regarding the bioavailability and content of essential mineral elements in foods that are thought to be unhealthy. Moreover, a big lot of discussions is devoted to the questionable influence of cooking processes, such as microwaving or reheating, of foods in containers and throw-away packing. Fast food essay topics also include the evaluation of food technology and its line of development, and therefore, the contemporary reader is welcome to acquire an understanding of all the hazardous and convenient sides of ready-to-eat foods.
The content of essential minerals in fast foods: the comparison of products and ready-to-eat comestibles
Here we will try to revise some available data pertinent to general dietary habits and food selection in order to contribute to the reader’s understanding of the minerals quantity importance. The main minerals essential for the human’s organism are as follows:
- Calcium (Ca) is probably the most valuable nutrient and the leading contributors to the Ca intake are milk and dairy products as well as vegetables, cereals, fish, dried fruits and legumes. Unfortunately, fast foods do not include many of these products. At the same time, one can easily find a case study template related to studies of fast foods consumption, and many of them claim that children’s rations these days consist of fewer dairy products and fruits due to the prevalence of snacks and soft drinks. As regards the content of Ca into fast foods, the lowest score were demonstrated by apple pie and salty French fries (from 12 to 50 mg/100g), whilst the highest amount of calcium was found in cheeseburger, pizza, chocolate donuts and vanilla custard (192, 112, 100 and 80 mg/100g, respectively). Certainly, neither table-service restaurants nor bistros could meet the recommendations for the calcium intake (up to 900 mg per day for adults) if to compare with a balanced and healthy diet.
- Iron (Fe) also plays an indispensable role for human organism’s functions. Not infrequently, students of medicine choose to investigate methods of Fe detection for their thesis methodology . The recommended daily intake of Fe is 17-19 mg for females and 7-9 mg for males. Predominantly, the natural sources of Fe are cereals, vegetables, meat, liver, fruits, nuts, and legumes. Hence, among fast foods most abundant with Fe are breakfast cereals enriched with fruits as well as chocolate donuts, chicken sandwiches, fish burgers and pizza. Simultaneously, cheese-tomato-pasta and vanilla custard were said to have the lowest amount of Fe. Accordingly, the main comestibles rich of this mineral are fish, poultry and meat; also, these products stimulate the absorption of nonheme iron, which makes them even more wholesome.
- Magnesium (Mg) is the element, which often becomes the subject-matter of the discussion in every other fast food essays. The recommended daily amount of Mg ranges from 400 to 420 mg per day for males and from 310 to 320 mg/d for females. Although magnesium can be discovered in almost all foods – fish, cereals, tofu, ice cream, honey, etc. – the people in developed countries definitely not always receive sufficient amounts of Mg with fast foods. One more time, pizza and hamburgers can boast of 27 and 29 mg/100 g respectively, whereas muffins and vanilla custard hold the lowest positions (up to 10 mg/100g) in this contest. However, the total amount of Mg in different fast foods can vary greatly owing to different contents of these elements in base products, such as cheese, potato, and flour.
- Zinc (Zn) is the fourth essential element that defines normal growth and well-developed immunity. The usual daily intake of Zn can be defined precisely if to follow any more or less authoritative science paper published by The US Institute of Medicine; it makes up 11,5 mg for men and 8,2 mg for women. Fish (esp. shellfish), meat products, tofu, cereals, and eggs are comestibles most abundant with Zn, which makes quiches and meat shawarma the leaders of fast foods that are rich in zinc. Among ready-to-eat foods that are characterized by the lowest level of Zn are croquettes, cheese-tomato-pasta and breakfast cereals.
- Copper (Cu) is also an inevitable mineral, and there is no way one can write a critical essay about fast food without mentioning the importance of Cu. The average daily amount of Cu sufficient for both men and women is 900 µg/d, and eggs, meat, vegetables, beverages, and cereals are the main contributors to the intake of copper. It was observed that confectionery containing sugar or sweeteners, such as biscuits, milk and dark chocolate, Viennese bread and ice-cream represent foods most abundant with Cu.
