Your fun task to do

Make a healthy salad/sandwich. Use multiple ingredients.

Draw a table. Write down all the ingredients used in the first column. 

Mention whether the ingrediant is from a plant source or an animal source in the second column. 

In the third column write down the nutrients obtained from this ingredient and say how it helps your body.

Take a picture of yourself at work and paste it. You could do this on an A4 size paper.

WEEK 2

We have all heard that we need to strengthen our immune system in order to be able to fight any disease. To do that we should ensure that we should eat right. Too much or too less of any nutrient will adversely affect our body and we will suffer from various diseases. We have learnt that too much consumption of fatty substances leads to obesity and thus cardiovascular diseases. Too little consumption may lead to deficiency diseases.

I would like you to collect pictures to show me 3 different types of diets that people follow and you also need to explain the advantages of that particular diet. You  may also include a diet plan for a person suffering from a particular disease.

Eg, this is a picture showing a diet that includes turmeric, ginger, cinnamon, fruits like banana.mango and pineapple and carrots to improve our immune system. This diet helps to protect us against diseases.
