Flu busting vegetable soup

flu busting soup | vegetable soup

Looks like our soup season has started off a bit earlier than anticipated!! The weather is so rainy and being in isolation, just needs the soothing comfort of the good flu busting soup. As of now some Netflix, comfy PJs and the warmth from the bowl of vegetable soup are keeping us going.

Why does mixed vegetable soup work in flu?

There have been studies done on why broth and soup can be perfect when you are unwell.
Firstly they keep you hydrated. Keeping oneself hydrated is really important when the temperature fluctuates and the body is trying its best to work its immune mechanisms. Most soups are easily digestible providing nourishment without being overburdened. The warmth of the soup soothes the throat and the comfort of holding that bowl of soup. This is the best comforting idea when you are unwell. The flavours added to the soup are certainly the ones that ease up congestion and cold.

What makes this flu busting soup work?

The spices in this soup -we have added pepper, turmeric, ginger and garlic. All these ingredients are well known in the natural medicine world to provide relief from upper respiratory tract congestion. With antibacterial and antiviral properties,  the spices certainly provide toasty warmth.
The vegetable medley- a colourful mix of veggies certainly contributes to the functional upkeep of nourishment and colour, thereby providing vital minerals and vitamins to the body. There is no hard and fast rule about the vegetables to have in this recipe. Any mild-tasting, the quick-cooking vegetable will be perfect. I have chosen vegetables that provide colour as well as nourishment today like broccoli, peppers ( capsicum)  and carrots. Paired with the basic onion tomatoes this is a nourishing combo. Add spinach or kale to this vegetable soup you like too.
Good protein -The cooked lentils provide the necessary protein that aids the soup to be filling and nutritious. If not lentils, cooked beans will be perfect in this recipe.
The herbs- The freshness of the soup comes from herbs. I like the taste of lemongrass in soups especially when I am ill. The coriander leaves provide a lemony feel to the overall recipe.

Do we need to add cheese?

Stirring in some grated mozzarella just before you eat is tasty and thickening. But I prefer to have it without as digestive power during the flu is low and hence important to keep it simple.

Serving this soup

When you are sick or in isolation, the biggest thing you want to to keep your tummy going with soothing foods that call for minimal prep work. Since soups generally work as a dump and go, serve it with some garlic bread or plain toast to make it worth a meal. Alternatively, you can add a quarter cup of quinoa or bulgar to this as it cooks to make this vegetable soup hearty.

Storage for later.

If you are making a couple of meals out of this flu busting soup that is a good idea. It stays well in the fridge for 2 days and reheats perfectly. However, I am not keen on freezing these are you need them fresh when you are unwell.
