Provide answers to questions about alcohol consumption and the importance of warm-ups before exercise.

Here are the answers to Question 1 and Question 2. Question 1: a) Four common reasons why people consume alcohol: • Socializing and celebration: Alcohol is often consumed in social settings to relax, celebrate, or enhance social interactions. • Stress relief and coping: Some individuals use alcohol to cope with stress, anxiety, or emotional difficulties. • Cultural and traditional practices: In many cultures, alcohol plays a role in rituals, traditions, and social norms. • Peer influence and perceived enjoyment: People may consume alcohol due to peer pressure or the belief that it enhances enjoyment and pleasure. b) Warm-up is important before exercise because: • It increases blood flow and muscle temperature, making muscles more flexible and less prone to injury. • It gradually elevates heart rate and breathing, preparing the cardiovascular system for increased activity. • It improves joint mobility and reduces stiffness, allowing for a greater range of motion. • It mentally prepares the individual for the upcoming physical exertion, improving focus and coordination. c) A sedentary lifestyle impacts health by: • Increasing the risk of chronic diseases such as obesity, type 2 diabetes, heart disease, and certain cancers. • Weakening muscles and bones, leading to muscle atrophy and decreased bone density. • Contributing to poor mental health, including increased risks of anxiety and depression. • Slowing down metabolism, which can lead to weight gain and impaired ability to process fats and sugars. d) Arranging the following according to the 30-40-30 rule (30% protein, 40% carbohydrates, 30% fat): • Protein (30%): Grilled chicken • Carbohydrates (40%): Brown rice • Fat (30%): Avocado e) Fibre benefits someone with diabetes by: • Slowing down sugar absorption, which helps prevent rapid spikes in blood glucose levels after meals. • Improving insulin sensitivity, allowing the body to use insulin more effectively. • Promoting satiety, which aids in weight management, a crucial aspect of diabetes control. • Lowering cholesterol levels, reducing the risk of cardiovascular complications often associated with diabetes. Question 2: a) Differentiate between malnutrition and overnutrition: • Malnutrition is a broad term referring to a condition that results from a diet in which nutrients are either not enough or are too much, such that the diet causes health problems. It encompasses both undernutrition (deficiency of nutrients) and overnutrition. • Overnutrition is a specific type of malnutrition where the intake of nutrients, especially calories, is excessive. This often leads to an accumulation of body fat (obesity) and can result in health issues like type 2 diabetes, heart disease, and high blood pressure. b) Breastfeeding is prioritized over formula for infants because: • Nutritional completeness: Breast milk provides all the essential nutrients in the perfect balance for an infant's growth and development. • Immune protection: It contains antibodies, enzymes, and white blood cells that protect infants from infections and diseases. • Easier digestibility: Breast milk is naturally easier for an infant's digestive system to process compared to formula. • Promotes bonding and development: It fosters a strong bond between mother and infant and supports optimal cognitive and physical development. c) Two ways alcohol affects the central nervous system (CNS): • Depressant effect: Alcohol acts as a CNS depressant, slowing down brain activity. This leads to impaired judgment, reduced coordination, slurred speech, and slowed reaction times. • Neurotransmitter disruption: It interferes with the balance of neurotransmitters in the brain, such as increasing the inhibitory effects of GABA and decreasing the excitatory effects of glutamate, resulting in sedation and cognitive impairment. d) The role of fibre in digestion: • Adds bulk to stool: Insoluble fiber adds bulk to fecal matter, which helps food move more efficiently through the digestive tract, preventing constipation. • Promotes gut health: Soluble fiber ferments in the colon, feeding beneficial gut bacteria and producing short-chain fatty acids that are vital for gut health. • Regulates nutrient absorption: Soluble fiber slows down the absorption of glucose and cholesterol, contributing to stable blood sugar levels and lower cholesterol. e) Advice for a diabetic patient on choosing carbohydrates: • Prioritize complex carbohydrates: Choose whole grains (e.g., brown rice, oats, whole wheat bread), legumes, and non-starchy vegetables, which have a lower glycemic index and cause a slower, more gradual rise in blood sugar. • Limit refined carbohydrates and added sugars: Avoid sugary drinks, white bread, pastries, candies, and highly processed foods, as these lead to rapid spikes in blood glucose. • Focus on fiber-rich options: Select carbohydrates high in fiber to help manage blood sugar levels, improve satiety, and support digestive health. • Practice portion control: Be mindful of carbohydrate portion sizes to effectively manage blood glucose levels and overall calorie intake.
