Cancer Diet: Best Recipes to Prevent Dehydration

by Dr Krishna Priya

Many cancer patients experience dehydration during treatment. We help you prevent this in three delicious ways.

 If you notice that your mouth and tongue are dry often, you might be at risk of dehydration. Other symptoms of dehydration include dizziness, extreme tiredness, dry skin, constipation, nausea and headaches. 

Dehydration results from not consuming enough water, or when your body loses water rapidly through diarrhea, vomiting or sweating. 

One of the easily noticeable symptoms of dehydration is dryness of the mouth and throat. But lack of sufficient water affects a lot more than just your mouth. Your cells and internal organs depend heavily on water for their proper functioning. 

If you do not consume enough water, you affects all of these:

  • The temperature of your body
  • The removal of wastes and toxins from your body
  • Your heart rate and blood pressure
  • Putting your eyes, mouth and ears at risk
  • Reducing the nutrients and oxygen in your body
  • Lubrication of your joints
  • Production of saliva

How can dehydration be prevented?

Drinking too much water at a time might lead to vomiting. Try sipping water through-out the day instead. There are a variety of eco-friendly and convenient bottles designed specifically to allow you to carry them with you at all times. 

Home-made popsicles without any artificial colours, and ice cubes might help you soothe your mouth and tongue. You can also consume these in flavours that reduce your nausea.

Here are some simple and tasty recipes to help you consume more liquids to prevent dehydration. 

1. Muskmelon and Cucumber Cooler

Muskmelons are rich in vitamin C which improves digestion, and potassium which helps control blood pressure. Additionally, muskmelons also contain vitamin A which help with hair regrowth. 

This recipe uses a single cup of chopped cucumbers which complete 19% of your daily requirement of vitamin K. It also gives you vitamins B and C, along with copper, potassium and magnesium. 


Muskmelon: 2 cups, peeled, deseeded and cubed

Cucumber: 1 cup, peeled, deseeded and cubed

Mint leaves: 1 tbs, finely chopped

Salt: a pinch


  • Use a juicer to blend the muskmelon and the cucumber cubes.
  • Strain the juice through a sieve, if you prefer a thin juice. 
  • Add the mint leaves and salt.
  • Serve chilled.

2. Green Smoothie

Green smoothies are made from leafy vegetables like spinach, kale or bok choy. Since spinach is easily available in India, we have used it in this recipe. 

Spinach is a superfood. It is loaded with vitamins, protein, iron and minerals. 

While spinach is extremely nutritious for you, consuming it in a smoothie can be difficult as it can taste bitter. To balance this taste, we use ripe and sweet fruits like banana and apple. You can also use mangos if they are in season. 


Spinach: 1/2 cup, chopped

Banana: 1/2 cup, ripe, chopped (you can also use mango or pineapples in place of banana)

Apple: 1/4 cup, chopped

Water: 1 cup


Use a juicer to blend the spinach, the peeled fruits and the water together.

3. Sunset Juice
