Worked Solution & Example Answer:‘More than a quarter of young people growing up in Ireland are obese or overweight according to the latest Growing Up in Ireland survey.’ (www.irish examiner.com) The table below shows nutritional information per 100 g, for full fat, low fat and fat free natural yoghurt - Leaving Cert Home Economics - Question 1 - 2021
Step 1
Using the information presented in the table, state which of the yoghurts you would recommend for an obese person. Give four reasons for your choice.
Answer
I would recommend the fat free natural yoghurt for an obese person.
Reasons:
- Low-Calorie Content: The fat free natural yoghurt contains only 54 kcal per 100 g, which is significantly lower than the full fat (133 kcal) and low fat (65 kcal) options. This can help reduce overall caloric intake, an essential factor in weight management.
- Reduced Fat and Saturates: With only 0.4 g of fat and 0.2 g of saturates, this option supports lower fat consumption, which is beneficial for individuals trying to manage their weight.
- Higher Carbohydrate Content: Although slightly higher in carbohydrates at 7.6 g, the fat free yoghurt can provide a quick source of energy without adding unnecessary fats.
- Similar Protein Content: With 4.8 g of protein, it delivers an adequate amount of protein needed for satiety compared to the fat free option, aiding in maintaining muscle while promoting weight loss.
Step 2
State three causes of obesity.
Answer
- Imbalance in Energy Intake: Consuming more calories than the body expends, often due to a sedentary lifestyle and high-calorie dietary choices.
- Psychological Factors: Conditions such as depression and emotional eating can lead to overeating.
- Genetic Predisposition: Family history can play a significant role in obesity, as genetics can influence metabolism and fat storage.
Step 3
Give an account of lipids (fats) under each of the following headings: classification.
Answer
Lipids can be classified into several categories:
- Animal Lipids: Found in animal fats, such as butter and lard.
- Plant Lipids: Derived from plants, including oils such as olive and canola oil.
- Saturated Fats: Typically solid at room temperature and found in animal products.
- Unsaturated Fats: Usually liquid at room temperature and found in plant oils; can be further divided into monounsaturated and polyunsaturated fats.
Step 4
Give an account of lipids (fats) under each of the following headings: functions in the body.
Answer
- Energy Storage: Fats serve as a major energy reserve, storing more energy per gram than carbohydrates or proteins.
- Cell Structure: Lipids are crucial components of cell membranes, contributing to the structure and integrity of cells.
Step 5
Step 6
Discuss four factors to be considered when selecting and buying foods to reduce fat intake in the diet.
Answer
- Nutritional Labels: Review fat content and prefer products labeled as low-fat or fat-free to make healthier choices.
- Cooking Methods: Opt for cooking methods that require less fat, such as steaming or grilling instead of frying.
- Whole Foods vs. Processed Foods: Choose whole foods that are naturally lower in fat; processed foods often contain unhealthy trans fats.
- Plan Meals: Preparing meals at home allows control over ingredients, reducing reliance on high-fat convenience foods.
