Worked Solution & Example Answer:'Fruit and vegetables are highly nutritious and an essential part of the diet, however only 21% of adult men and 19% of women in Ireland are meeting the current World Health Organisation target, with young children eating even less.' (a) Discuss (i) the nutritional significance and (ii) the contribution to the diet of fruit and vegetables - Leaving Cert Home Economics - Question 2 - 2008
Step 1
(i) Discuss the nutritional significance
Answer
Fruit and vegetables are rich sources of essential nutrients, including vitamins A, C, E, and various B vitamins. They provide dietary fiber, which aids digestion and helps maintain a healthy weight. Additionally, antioxidants found in fruits and vegetables combat oxidative stress, thereby reducing the risk of chronic diseases like heart disease and cancer. The low energy density of these foods makes them beneficial for weight management.
Step 2
(ii) Discuss the contribution to the diet
Answer
Fruits and vegetables contribute significantly to a balanced diet by providing a variety of flavors, colors, and textures. They offer hydration, important for overall health, and can replace higher-calorie foods. The inclusion of fruits and vegetables can lead to improved overall nutrient intake, helping to fulfill dietary recommendations and promoting optimal health.
Step 4
Explain the underlying principle of the method of preservation you have selected
Answer
Jam-making involves the correct proportion of sugar, which serves multiple purposes: it creates a concentrated solution that inhibits microbial growth, helps to preserve the fruit and enhances flavor. The process also involves heating to destroy enzymes and microorganisms, while pectin acts as a gelling agent, providing texture and helping to prevent spoilage.
Step 5
Write an informative note on food irradiation
Answer
Irradiation is a physical treatment where food is exposed to a defined dose of ionizing radiation. This method eliminates harmful microorganisms, reduces spoilage and extends shelf life by disrupting the DNA of pests and pathogens. It preserves the nutritional quality of food, allowing fruits to retain their color and texture. In the European Union, foods treated by irradiation must be labeled with the Radura symbol, indicating they have undergone this process.
