Yes, you can get some of your water from different food sources. Obvious things like watermelon, rockmelon (cantaloupe), strawberries and celery are high in water content. Leafy greens like lettuce, cabbage and spinach also contain a large percentage of water. Eating soups, laksa and broths are another way to hydrate from food, while adding things like cucumber, tomatoes and capsicum to a salad is a simple way.
I appreciate you explaining that rainwater is devoid of harmful pollutants and that some simple filtering can provide you with pure, delicious drinking water that you will like and want to consume more of. I find this information super exciting as I’ve been looking for ways to live more sustainably. I feel like purchasing a rainwater filter system can help me achieve this goal so I will be looking further into that.
