Different Tastes

We eat different types of food items that have different tastes and smells. The taste of some food items is pleasing while the taste of several other food items irritates us. We do not like to eat food items having the same taste again and again because we get bored of the same taste over time.

Here are different food items and their taste:

  • Food items having sweet taste: Sugar, Kheer, Jalebi, Gulab Jamun, Apple, Banana, Jaggery etc.
  • Food items having salty taste: Samosa, Dal, Chicken, Meat, Cooked Vegetables, Aalu Bhujia, Fried peanuts.
  • Food items having sour taste: Citrus fruits, Tamarind (imli), Gooseberries, Cranberries, Grapes, Kiwi, Apples.
  • Food items having bitter taste: Bitter gourd, Broccoli, Citrus peel, Cocoa, Coffee, Beer, Red wine.
  • Food items having pungent taste: Chilies, Garlic, Ginger, Hot peppers and Onions etc.   From Tasting to Digesting Class 5 Notes EVS Chapter 3

Closing Eyes and Identifying Food

  • We can tell about various food items without seeing them. We identify different food items by just tasting them or smelling them.
  • We taste the food item with the help of our tongue. Our tongue has a rough surface due to tiny bumps on it. These tiny bumps on the tongue are called taste buds and help us in tasting different food items.

How do we taste food?

  • When we put a food item in our mouth, the saliva on our tongue mixes with the food item and after that reaches taste buds and we get to know the taste of the food item.
  • If we wipe the front part of the tongue and make it dry and then put a food item on it, we will not able to get the taste of the food item because the taste does not reach the taste buds.

From Tasting to Digesting Class 5 Notes EVS Chapter 3

  • The front end of our tongue tastes sweet and salty food items.
  • The side parts of our tongue identify the taste of sour food items.
  • The back end of the tongue identifies the taste of bitter food items.

Chew it or Chew it Well: What’s the difference?

The food that we eat goes into our stomachs through the food pipe after we swallow it. After that food is digested and is used by different parts of the body. We chew the food that we eat. Our elders usually tell us to eat slowly and chew the food thoroughly. The chewing is the first step in the digestion of food.

  • Digestion is the process of the breakdown of food items to obtain energy from them.
  • Chewing is a process in which food is broken down into smaller particles with help of our teeth.
  • The smaller particles of food are easy to digest.
  • After from breakdown of food into smaller particles, it is also mixed with saliva which breakdown some components of foods into simple ones.

How do we know we are hungry?

  • When we have a strong urge to eat something, it means we are hungry.
  • Also, if our stomach feels empty, it means we are hungry.
  • If we do not eat food for 2 or 3 days, we feel tired and dizzy and may fall ill.

What do we have to do in case of water loss from our body?

  • If we have loose motions and vomiting, we lose a sufficient amount of water and salts from our bodies.
  • If this loss of water and salts is not made up, or body will dehydrate.
  • We should use oral rehydration solutions (salt and sugar solution) to recover the loss of water and salts.
  • If we are not able to eat something, a glucose drip is given to us. Glucose provides instant energy to the body without eating.

FAQs on From Tasting to Digesting Class 5 Notes EVS Chapter 3

1. How do our taste buds work to help us taste food?
Ans. Our taste buds are located on our tongue and they are responsible for our ability to taste different flavors. When we eat food, the molecules from the food come into contact with our taste buds. These taste buds send signals to our brain, which then interprets the signals as different flavors like sweet, sour, salty, or bitter.
2. Is it true that different parts of the tongue can taste different flavors?
Ans. No, it is a common misconception that different parts of the tongue can taste different flavors. In reality, all taste buds on the tongue can detect all flavors. The idea that certain areas of the tongue are specialized for specific tastes is a myth.
3. How does our body signal that we are hungry?
Ans. Our body signals hunger through a combination of physical and chemical cues. When our stomach is empty, it releases a hormone called ghrelin, which signals to the brain that we are hungry. Additionally, our blood sugar levels can also drop when we haven't eaten for a while, triggering hunger signals.
4. What should we do if our body loses water?
Ans. If our body loses water, it is important to replenish it to avoid dehydration. We should drink plenty of fluids, especially water, to rehydrate our body. Additionally, consuming foods with high water content, such as fruits and vegetables, can also help in restoring the lost water.
5. How does closing our eyes affect our ability to identify food?
Ans. Closing our eyes can heighten our sense of taste because it eliminates the visual cues that can influence our perception of food. When we close our eyes, our focus shifts solely to the taste and texture of the food, allowing us to concentrate on its flavors. This can result in a more enhanced and accurate identification of the food we are eating.
