Mindful Eating: A Pathway to Health - What Do We Eat?

Grade 6CBSE

Review the key concepts, formulae, and examples before starting your quiz.

🔑Concepts

•

Nutrients are the chemical components in food needed by our body for growth, energy, and repair. The major nutrients are Carbohydrates, Proteins, Fats, Vitamins, and Minerals.

•

Carbohydrates and Fats are known as 'Energy-giving foods'. Fats provide significantly more energy compared to the same amount of carbohydrates: Energyfats>EnergycarbohydratesEnergy_{fats} > Energy_{carbohydrates}.

•

Proteins are 'Body-building foods' essential for the growth and repair of body tissues.

•

Vitamins and Minerals are 'Protective foods' that help in protecting our body against diseases. For example, Vitamin C helps the body fight many diseases, and Calcium (CaCa) is needed for strong bones.

•

Roughage (Dietary Fiber) and Water are also essential. Roughage helps our body get rid of undigested food, while Water helps in absorbing nutrients and flushing out waste as urine and sweat.

•

Mindful Eating is the practice of being fully attentive to the food we buy, prepare, and consume. It involves recognizing hunger cues and choosing a 'Balanced Diet' that contains all nutrients in the right proportions.

•

Test for Starch: Adding 2-3 drops of dilute Iodine solution to food turns it blue-black, indicating the presence of starch.

•

Test for Protein: Mix mashed food with 22 drops of Copper Sulphate (CuSO4CuSO_4) and 1010 drops of Caustic Soda (NaOHNaOH). A violet color indicates protein presence.

•

Test for Fats: Rubbing food on a piece of paper leaves a translucent/oily patch, confirming the presence of fats.

📐Formulae

Total Energy (kcal)≈(4×masscarbs)+(4×massproteins)+(9×massfats)Total\ Energy\ (kcal) \approx (4 \times mass_{carbs}) + (4 \times mass_{proteins}) + (9 \times mass_{fats})

Nutrient Intake=Consumed AmountRecommended Daily Allowance×100Nutrient\ Intake = \frac{Consumed\ Amount}{Recommended\ Daily\ Allowance} \times 100

Food+Iodine→Blue-Black color (Starch positive)\text{Food} + \text{Iodine} \rightarrow \text{Blue-Black color (Starch positive)}

Food+CuSO4+NaOH→Violet color (Protein positive)\text{Food} + CuSO_4 + NaOH \rightarrow \text{Violet color (Protein positive)}

💡Examples

Problem 1:

A snack contains 15 g15\text{ g} of carbohydrates and 5 g5\text{ g} of fats. Calculate the total energy provided by these two nutrients.

Solution:

15×4=60 kcal (from Carbs)5×9=45 kcal (from Fats)60+45=105kcal\begin{array}{r} 15 \times 4 = 60 \text{ kcal (from Carbs)} \\5 \times 9 = 45 \text{ kcal (from Fats)} \\ \hline 60 + 45 = 105 \text{kcal} \end{array}

Explanation:

Carbohydrates provide 4 kcal/g4\text{ kcal/g} and fats provide 9 kcal/g9\text{ kcal/g}. By multiplying the mass of each nutrient by its energy value and adding them, we get the total energy of 105 kcal105\text{ kcal}.

Problem 2:

During a science experiment, Rahul added 22 drops of CuSO4CuSO_4 and 1010 drops of NaOHNaOH to a solution of crushed pulses. What change will he observe?

Solution:

The solution will turn Violet in color.

Explanation:

Pulses are rich in proteins. The chemical reaction between protein, Copper Sulphate (CuSO4CuSO_4), and Caustic Soda (NaOHNaOH) produces a violet color, which is a standard test for protein detection.
