unfiltered water

Did you know water plays a significant role in the taste of food?

Yes, you read that right. Good quality water raises the oomph factor of your meal making the dish tastier.

Using tap water for cooking purposes is quite normal. But whether that water is completely free of impurities, one cannot be fully sure. According to recent research, the contaminants in tap water can affect human health, and more so when it is being used for cooking.

So, if you want your meals to be a spread of delectable delicacies, filtered water is one sure-short way of ensuring that. Plus, by reducing the levels of contaminants within the water, you are ensuring your drinks and foods are healthier and less harmful to the body over time.

Health implications

Tap water, even though treated, contains a trace amount of metals and other common contaminants which on prolonged, regular consumption through cooking, also start to be deposited in the human body. With the increased micro-deposits in the body, cells start to be affected, and in effect which consequently affect the overall health of the individual.

Here is a list of common contaminants in India’s tap water


Tap water is commonly treated with Chlorine to free it of sediment and bacteria. However, regular consumption of chlorine-treated water can mean ingesting a high level of chlorine which impairs an individual’s health. One health concern of frequent Chlorine consumption relates to the respiratory system. Chlorine can be found to block the airway which causes chest pains for the individual. It can also affect the digestive system, resulting in diarrhea and other gastric-related health problems. Furthermore, bacteria such as E Coli can live on in your tap water despite it having been treated with chlorine.


If Arsenic is present in water, at a limit above the WHO permissible guidelines, regular consumption is associated with the risk of cancer.


Cadmium is a metal that naturally occurs in zinc, lead, or copper ores. Its presence in tap water has a series of short-term and long-term impacts on human health. The short-term health concerns include individuals feeling nauseous or experiencing vomiting, diarrhea, renal failure, convulsions, and shock. The long-term implications are grave concerns like kidney, liver, or brain damage.


Though zinc is naturally present in water, a high proportion of it could be the cause of nausea, cramps, and vomiting. Besides that, zinc also adds an unwanted flavor to the water.


Utilized as a mineral for flowers and plants, a high percentage of nitrates are commonly left behind in the groundwater. Drinking water infused with nitrates can tamper with the health of infants and pregnant women.

Now that you know the common contaminants to look out for and how they individually can affect your health, we are taking a look at how they affect the taste of your drinking water and food.

Taste Implications

Unfiltered water with its contaminants lends an unpleasant taste to food. At times, it is also responsible for giving food a foul odor. Affix a water filter and you will notice a significant difference in the taste of your food. Not only will a filter improve the taste of your water, but you will come to realize that beverages are more flavourful than before and baked goodies are fluffier when baked with filtered water as it increases yeast efficiency and slows down the fermentation process.
