    Which of the following is a good source of vitamin C?

    • Arrots

    • Oranges

    • Spinach

    • Almonds

    Correct Answer
    A. Oranges
    Explanation
    Oranges are an excellent source of vitamin C, also known as ascorbic acid. Vitamin C is a water-soluble vitamin that plays a crucial role in immune function, collagen production, and wound healing. It's also a powerful antioxidant, protecting cells from damage caused by free radicals. Because vitamin C is not stored in the body, it's important to consume it regularly through foods like oranges, grapefruits, lemons, strawberries, and bell peppers. Getting enough vitamin C can help boost your immune system and keep you healthy.

    Correct Answer
    A. Diabetes
    Explanation
    People with diabetes must carefully monitor and regulate their blood sugar levels because diabetes is a condition characterized by high blood sugar levels. Failure to manage blood sugar levels can lead to various complications such as heart disease, kidney damage, nerve damage, and vision problems. Therefore, individuals with diabetes need to regularly monitor their blood sugar levels, take medications as prescribed, follow a healthy diet, and engage in regular physical activity to keep their blood sugar levels within a target range.

    Explanation
    Milk and other dairy products are excellent sources of calcium. Calcium is a vital mineral for building and maintaining strong bones and teeth. It also plays a role in muscle function, nerve transmission, and blood clotting. If you don't consume dairy, you can also get calcium from fortified plant-based milks, tofu, and leafy green vegetables like broccoli and kale. Getting enough calcium throughout life is important for preventing osteoporosis, a condition that weakens bones and increases the risk of fractures.

    Correct Answer
    A. Body Mass Index (BMI)
    Explanation
    Body Mass Index (BMI) is a measure that calculates a person's weight in relation to their height. It is widely used to determine if a person's weight is healthy or not. BMI provides a numerical value that indicates whether a person is underweight, normal weight, overweight, or obese. By comparing an individual's BMI to the standard BMI ranges, healthcare professionals can assess the level of risk associated with their weight and provide appropriate recommendations or interventions. Therefore, BMI is a reliable measure to determine if a person's weight is healthy.

    • Vitamin D

    Correct Answer
    A. Vitamin C
    Explanation
    Vitamin C is found in oranges and is known for its immune-boosting properties. It helps prevent colds by enhancing the production of white blood cells, which are essential for fighting off infections. Additionally, vitamin C acts as an antioxidant, protecting cells from damage caused by harmful free radicals. Therefore, consuming oranges or other foods rich in vitamin C can help strengthen the immune system and reduce the risk of catching a cold.

    Which mineral is important for oxygen transport in the blood?

    • Calcium

    • Iron

    • Potassium

    • Sodium

    Correct Answer
    A. Iron
    Explanation
    Iron is essential for oxygen transport in the blood. It's a key component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. Without enough iron, your body can't produce enough hemoglobin, leading to iron deficiency anemia. Symptoms of anemia include fatigue, weakness, and shortness of breath. Good sources of iron include red meat, poultry, fish, beans, lentils, and leafy green vegetables. Consuming iron-rich foods along with vitamin C-rich foods can improve iron absorption.

    • Vitamin A

    • Vitamin B

    • Vitamin C

    • Vitamin D

    Correct Answer
    A. Vitamin A
    Explanation
    Vitamin A is important for eyesight because it plays a crucial role in maintaining the health of the retina, which is the part of the eye responsible for detecting light and color. It helps in the production of a pigment called rhodopsin, which is necessary for proper vision in low-light conditions. Additionally, vitamin A also supports the overall health of the cornea, the clear outer layer of the eye. A deficiency in vitamin A can lead to a condition called night blindness, where it becomes difficult to see in dim light.

    Correct Answer
    A. Calorie
    Explanation
    A calorie is a measure of the energy that is obtained from food. It represents the amount of energy required to raise the temperature of one gram of water by one degree Celsius. Therefore, when we consume food, the calories in that food provide us with the energy needed for various bodily functions, such as metabolism, physical activity, and growth.

    Explanation
    Fiber plays a crucial role in aiding digestion. It adds bulk to the stool, making it easier to pass through the digestive tract and preventing constipation. There are two types of fiber: soluble and insoluble. Soluble fiber dissolves in water and can help lower cholesterol levels, while insoluble fiber doesn't dissolve and primarily promotes regularity. Foods high in fiber include fruits, vegetables, whole grains, and legumes. A diet rich in fiber is not only beneficial for digestive health but also contributes to overall well-being by helping regulate blood sugar levels and promoting feelings of fullness

    Explanation
    Avocado is a great source of healthy monounsaturated fats. These fats are beneficial for heart health, helping to lower bad cholesterol levels and reduce the risk of heart disease. Unlike saturated fats found in butter and trans fats found in fried and processed foods, monounsaturated fats contribute to overall well-being. Avocados also provide other essential nutrients like fiber, potassium, and vitamins, making them a nutrient-dense choice for incorporating healthy fats into your diet. They can be enjoyed in various ways, from adding them to salads and sandwiches to making guacamole.

    A. Saturated fats
    Explanation
    Saturated fats should be limited in the diet. These fats are often found in animal products like red meat, butter, and cheese, as well as some plant-based oils like coconut oil and palm oil. Consuming too much saturated fat can raise bad cholesterol levels, increasing the risk of heart disease. It's recommended to replace saturated fats with healthier unsaturated fats, such as monounsaturated fats found in avocados and olive oil, and polyunsaturated fats found in nuts, seeds, and oily fish

    What is the primary function of carbohydrates in the body?

    • Build muscle

    Carbohydrates are the body's main source of energy. When you eat carbohydrates, your body breaks them down into glucose, a type of sugar that your cells use for fuel. This energy is essential for everything from physical activity to basic bodily functions like breathing and thinking. While protein helps build muscle and fats provide long-term energy, carbohydrates are the quickest and most readily available source of energy for daily activities. Choosing complex carbohydrates like whole grains, fruits, and vegetables over simple carbohydrates like refined sugars is important for sustained energy release and overall health.

    • Carbohydrates

    • Protein

    • Vitamins

    Correct Answer
    A. Protein
    Explanation
    Protein is crucial for building and repairing tissues in the body. It's the building block of muscles, organs, skin, hair, and nails. From growth and development in childhood to maintaining and repairing tissues throughout life, protein plays a vital role. When you consume protein, your body breaks it down into amino acids, which are then used to create new proteins where needed. Good sources of protein include lean meats, poultry, fish, eggs, beans, lentils, and dairy products. Getting enough protein in your diet is essential for maintaining a healthy body composition and supporting various bodily functions.

Antioxidants neutralize free radicals, preventing them from harming cells. Many fruits and vegetables are rich in antioxidants, including vitamins C and E, as well as compounds like beta-carotene and flavonoids. Eating a diet rich in antioxidant-rich foods can help reduce the risk of chronic diseases like heart disease, cancer, and Alzheimer's disease.
