Reverse osmosis is a method of filtering water that removes many contaminants, including heavy metals andsediments like chlorine, salt, viruses, bacteria, and microorganisms. This process works by pushing water through a semi-permeable or synthetic membrane.

Reverse osmosis water is considered to be one of the cleanest forms of water. However, along with removing potentially harmful compounds, reverse osmosis alsoremoves important minerals from water. In this article, we have outlined the benefits and health risks that come fromdrinking reverse osmosis water.

Is Reverse Osmosis Water Beneficial to Your Health?

There are two strong answers to this question. The World Health Organization (WHO) warns that drinking reverse osmosis water is unsuitable for long-term human consumption and could negatively impact human health.

On the other hand, people believe that reverse osmosis water is beneficial because it is purified and free from potentially harmful compounds that could cause illness and disease.

What Is Removed From Water by Reverse Osmosis?

Reverse osmosis filters remove organic matter, sediment, sodium, copper, lead, calcium, iron, magnesium, metal ions, aqueous salts, bacteria, viruses, and essential minerals. Reverse osmosis also reduces fluoride, arsenic, chlorine, nitrate, andtrihalomethane levels.

Advantages of Reverse Osmosis Water

The advantages of reverse osmosis water include the following.

Fewer Contaminants

Reverse osmosis filters are very effective and used to treat water on a large scale in wastewater plants and on a small scale in homes. Reverse osmosisremoves 98 percent of all contaminants from drinking water.

Clean Water on Demand

Reverse osmosis filters can be fitted directly onto your tap, providing clean drinking water on demand.

Softer Water

Water with a high mineral content is known as hard water. Hard water can cause scale, buildup in pipes, and other issues. Because reverse osmosis removes these minerals, it softens the water.

Tastier Food

The chemicals and minerals inunfiltered water can alter the taste of food when used in cooking. Many people report that reverse osmosis water results in better tasting food because it removes impurities and minerals.

Reduced Risk of Illness and Disease

Reverse osmosis water removes the potentially harmful microorganisms from water that could cause illness and disease.

Disadvantages of Reverse Osmosis Water

The disadvantages of reverse osmosis water include the following

Unusual Taste

One of the biggest disadvantages of reverse osmosis water is that it may have an unusual taste. Due to the removal of minerals, reverse osmosis can taste flat. Sometimes, the reverse osmosis process can also give water afishy smell.

Health Implications

The WHO has warned that long-term consumption of reverse osmosis water could result in negative health effects. Reverse osmosis is essentially demineralized water, which leeches minerals from the body. Leeching minerals from the body means that the minerals consumed via food and vitamins are urinated away. Fewer minerals consumed and more minerals being excreted means negative side effects and health problems.

It is believed that the reduced mineral intake from water cannot be completely compensated for through diet. People who drink reverse osmosis water as their main source of water could experience side effects like fatigue, muscle cramps, weakness, cardiovascular disorders, or hypertension in severe cases. Critics suggest that drinking reverse osmosis water also deprives the body of electrolytes.

Reverse osmosis water throws off homeostasis in the body, which causes a 20 percent increase in the need to urinate. An unbalanced homeostasis system leads to increased levels of thirst.

Can Reverse Osmosis Water Make You Dehydrated?

Reverse osmosis has no electrolytes and a lower pH level. It is actually considered to be acidic, which has negative implications on the body. Reverse osmosis water does not hydrate the body as well asalkaline water, which could result in progressive dehydration.

Should You Drink Reverse Osmosis Water?

There are advantages and disadvantages to drinking reverse osmosis water. Reverse osmosis is a beneficial solution if you live in an area plagued by many water concerns, like excess herbicides, pesticides, or polluted water. It is also a good option for when you visit a place with questionable local water, like when you go on holiday.

Eating a healthy, balanced diet and taking supplements could compensate for the loss of essential minerals. However, in the world we live in, most people don’t receive all the minerals they need from their food. Therefore, drinking reverse osmosis water could result in mineral deficiencies and negative health effects.
