Test: Food and its Components - Class 6 MCQ

• Fat: Fats are composed of carbon, hydrogen, and oxygen, but they contain less oxygen compared to carbohydrates. Fats have a higher proportion of carbon and hydrogen atoms relative to oxygen atoms.


• Carbohydrate: Carbohydrates, such as starch, have a higher proportion of oxygen atoms compared to fats. This is because carbohydrates are made up of carbon, hydrogen, and oxygen in a ratio where oxygen atoms are more abundant.


• Protein: Proteins also contain oxygen atoms, but they have a different chemical structure compared to carbohydrates and fats. Proteins are composed of amino acids, which contain nitrogen in addition to carbon, hydrogen, and oxygen.


• Vitamins: Vitamins can vary in their chemical composition, but they generally contain oxygen along with other elements essential for various biological functions in the body.

- Rice is primarily composed of carbohydrates, making it a staple energy source in many diets worldwide.
- Carbohydrates are essential nutrients that provide energy for the body, fueling brain function, muscle activity, and metabolism.

Proteins are needed for the growth and repair of our body. Foods proteins are often called ‘body building foods’

Deficiency of Vitamin B1 causes Beriberi

• Rickets: Deficiency of Vitamin D causes Rickets, not Vitamin B1.


• Beriberi: This is a condition caused by a lack of Vitamin B1 in the diet.


• Scurvy: Scurvy is caused by a deficiency of Vitamin C, not Vitamin B1.


• Goiter: Goiter is primarily caused by iodine deficiency, not Vitamin B1 deficiency.

Therefore, the correct answer is Beriberi. Beriberi is a condition that affects the nervous and cardiovascular systems and can lead to symptoms like fatigue, weakness, difficulty walking, and nerve damage. It is important to consume an adequate amount of Vitamin B1 through diet to prevent this deficiency-related condition.

• Vitamin B is a group of water-soluble vitamins that play essential roles in various bodily functions.


• Thiamine, also known as Vitamin B1, is crucial for energy metabolism and nerve function.


• Deficiency in Thiamine can lead to conditions like beriberi or Wernicke-Korsakoff syndrome.


• Food sources of Thiamine include whole grains, legumes, nuts, and lean meats.

Sugar is classified as a carbohydrate.

Energy Source: Sugars provide quick energy because they are easily broken down by the body.

Carbohydrates: Carbohydrates are the main source of energy for our bodies. When consumed, carbohydrates are broken down into glucose, which is then used by our cells as fuel for energy.

Fat: Fish are a great source of healthy fats which are important for brain function and reducing inflammation in the body.

Protein: Fish is a high-quality source of protein, which is essential for building and repairing tissues in the body.

Vitamin D: Fish is one of the few natural food sources of vitamin D, which is important for bone health and immune function.

Carbohydrate: Fish do not contain significant amounts of carbohydrates 

Answer:

The correct answer is option A: (i), (ii), (iii)

Therefore, fish mainly provide us with fat, protein, and vitamin D, making them a nutritious addition to a balanced diet.

• High Fat Intake: Obesity occurs when we consume a diet high in fats, especially saturated and trans fats. These fats are calorie-dense and can lead to weight gain if consumed in excess.

• Calorie Density: Fats have a high calorie content per gram, which can contribute to weight gain if not consumed in moderation.


• Lack of Nutrient Density: Foods high in fat often lack essential nutrients like vitamins and minerals, leading to overconsumption in order to meet nutritional needs.


• Impact on Metabolism: Excessive fat intake can negatively impact metabolism, making it harder for the body to burn calories efficiently.

• Healthy Eating Habits: Focus on a balanced diet that includes a variety of nutrients from fruits, vegetables, lean proteins, and whole grains.


• Regular Exercise: Physical activity plays a crucial role in maintaining a healthy weight and preventing obesity.


• Portion Control: Be mindful of portion sizes and avoid overeating, especially foods high in fats and calories.

Butter mainly contains:

• Fat: Butter is primarily composed of fat, specifically saturated fat.


• Vitamin: Butter contains fat-soluble vitamins such as vitamin A, D, E, and K.


• Protein: Butter does contain some protein, but it is not the main component.


• Calcium: Butter does not contain significant amounts of calcium.
