Debunking Myths: The Truth About Pure Water and Bone Health - Orthopedics

Minerals and Bones


Hello, doctor: Recently, I've heard people say that one should not drink pure water because it lacks minerals, which can lead to weakness and have negative effects on cells.
They also mentioned that U.S.
law prohibits drinking pure water.
I haven't studied much and don't understand these things, so I'm not sure if what that person said is true.
I came here to seek your advice.

I'm sorry, 20~29 year old female. Ask Date: 2003/06/02

Pure water is safe to drink, but it has very low or zero mineral content.
Long-term consumption without drinking other types of water can lead to mineral deficiencies in the body.
However, other foods and beverages also contain minerals, so if you are still using or consuming other types of water, it is unlikely to cause mineral deficiencies, and therefore, there is no need to worry too much.
Commercial multivitamin tablets also contain various minerals, which can be purchased for supplementation when necessary.

The concerns surrounding the consumption of pure water, particularly distilled or demineralized water, often stem from misconceptions about its effects on health, especially regarding bone health. Let's clarify these myths and provide a comprehensive understanding of the relationship between pure water, mineral intake, and bone health.

Firstly, it is essential to understand what pure water is. Pure water, such as distilled water, is water that has been purified to remove impurities and minerals. While it is true that pure water lacks minerals like calcium and magnesium, which are beneficial for health, the idea that drinking pure water will lead to immediate negative effects, such as "soft hands and feet," is exaggerated and not supported by scientific evidence.

The human body is remarkably resilient and can adapt to various dietary conditions. While long-term consumption of only pure water without any mineral intake could potentially lead to mineral deficiencies, this scenario is unlikely for most people. The average diet provides sufficient minerals through food sources such as fruits, vegetables, dairy products, and meats. Therefore, if an individual maintains a balanced diet, the occasional consumption of pure water should not pose a significant health risk.

Regarding bone health, the primary concern is not the type of water consumed but rather the overall intake of essential nutrients, particularly calcium and vitamin D. Calcium is crucial for maintaining bone density, and vitamin D helps the body absorb calcium effectively. Research indicates that inadequate calcium intake is a significant risk factor for osteoporosis, a condition characterized by weak and brittle bones. However, the relationship between water consumption and bone health is more nuanced.

Some studies suggest that high protein diets, particularly those rich in animal proteins, can lead to increased calcium excretion in urine, potentially affecting bone health negatively. This phenomenon is often referred to as the "calcium-protein debate." However, it is essential to note that the body requires a balance of nutrients, and both calcium and protein play vital roles in bone health. Therefore, rather than focusing solely on the type of water consumed, individuals should pay attention to their overall dietary patterns.

Moreover, the claim that U.S. laws prohibit the consumption of pure water is unfounded. There are no regulations that prevent individuals from drinking distilled or demineralized water. In fact, many people choose to drink such water for various reasons, including taste preferences and perceived purity.

In conclusion, drinking pure water is not inherently harmful, especially when consumed as part of a balanced diet rich in essential minerals. The key to maintaining bone health lies in ensuring adequate intake of calcium and vitamin D, along with a healthy lifestyle that includes regular weight-bearing exercise. If there are concerns about mineral intake or bone health, it is advisable to consult with a healthcare professional who can provide personalized recommendations based on individual dietary needs and health status.
