You've probably asked yourself too if that old bottle of water in your pantry is still good to drink? Water is life, yet there are remaining questions about the shelf life. Whether you are stockpiling for emergencies or wondering if that bottled water left in a heated car is safe to drink, understanding if and how water "expires" is essential. This article goes into the science behind water storage and its potential risks and practical tips to ensure your water will remain safe and consumable.

Water itself does not spoil or degrade. Chemically, pure water (H₂O) remains unchanged indefinitely. However, there are issues that arise due to the containers in which it is stored and the environmental conditions surrounding the storage.

In the United States, most bottled water has an expiration date. This labeling is often misunderstood as being an indication of the water's safety, but it mainly has to do with quality. The U.S. Food and Drug Administration (FDA) confirms that commercially sealed bottled water is safe to drink indefinitely if stored properly. Over time, though, the taste, smell, and even the appearance of water may change due to interactions with its packaging.

Role of Packaging in Water Safety

Plastic Bottles and Chemical Leaching

Bottled water is mostly packed in polyethylene terephthalate, PET plastic. Even though it is light in weight, resistant, and recyclable, this material is limited in other aspects. It leaches chemicals in trace amounts in the water if heated or placed under direct sunlight. For instance, do not leave your bottled water in the hot car for an extended period.

The next is bisphenol A or BPA. This chemical has been used to soften some plastics and is known for its hormone disruption. Many producers have shifted toward BPA-free materials, but older bottles and improper storage still pose risks. Bottles carrying recycling code #7 may be BPA-contaminated. There are also concerns over microplastics and long-term storage.

Microplastics and Long-Term Storage

Over time, the plastic in the bottle may leach into the water, causing some to question health risks. In 2019, one article published in the International Journal of Environmental Research and Public Health noted that these particles exist but are usually not at high enough concentrations to pose a problem if the water is properly stored.

How Long Can Water Be Stored Safely?

Bottled Water

Unopened bottled water, kept in a cool, dark place, remains safe to drink for years. But manufacturers often advise that it should be consumed within two years of its manufacture date for best quality. After this period, it may start showing off-flavors or odors due to contact with the plastic.

Tap Water

Tap water, under the Environmental Protection Agency (EPA), undergoes strict standards for safety. It can be kept in pure, BPA-free bottles up to six months. Afterward, it loses its fresh flavor or becomes dirty if not properly sealed.

Rainwater

Don't drink rainwater unless treated first. It usually contains contaminants that should not reach the human stomach. It should be used to water plants if not filtered and sterilized first.

Signs That Water Has Gone Bad

Water itself doesn't go bad, but extrinsic factors make it unsafe. Always discard water that has:

An off smell: An earthy, metallic smell indicates contamination.

Coloration: Greenish or bluish coloration signifies microbial growth or rust.

Unpleasant taste: A metallic or stale taste is a hallmark of degradation.

Froth or particles: Indicate dirt, germs, or other impurities.

How to Store Water Safely?

Avoid Heat and Sunlight

Store water in a cool, dark place and out of direct sunlight. Heat breaks down the plastic, allowing chemicals to leach out more easily.

Choose the Right Containers

For long-term storage, select BPA-free or food-grade plastic containers. The best alternatives are stainless steel and glass containers, which avoid all the risks that plastic poses.

Hygiene Maintained

Wash and sanitize the container before refilling. Always seal the lids so that no bacteria get inside.

Rotate Your Stock

Use a first-in, first-out rotation system with stockpiled water. This will mean that you will use the oldest water first to keep your water supply fresh.

Is It Safe to Drink Water Past Its Expiration Date?

The expiration date on bottled water is a mark of its quality, not safety. Although the water is safe to drink past this date, it is sensible to check it for any signs of spoilage as mentioned above. Tap water that has been stored for longer periods should be checked for clarity and odor before consumption.

Plastic bottles, although convenient, degrade the environment. Only a few percent of PET bottles are recycled, while the rest remain in landfills or oceans. Choose reusable containers and tap water whenever possible to minimize plastic waste and environmental damage.

Water is one of the most precious resources in this world, yet it can be safe only if it is kept appropriately. People may tell you that water does not expire, but the fact is that packaging materials, exposure to the environment, and storage conditions may affect the quality of the water. Proper storage techniques, opting for BPA-free containers, ensure that water remains fresh, safe, and ready for consumption at any time.

Have you been diagnosed with oral cancer? Wondering if you can have your favourite fruit, mango? Then make sure to consult your doctor before having it. Though mangoes are rich in vitamins and antioxidants, oral cancer patients should consume them carefully, depending on their treatment stage and mouth condition. It is not a good idea for oral cancer patients to eat mangoes in large quantities.

Can oral cancer patients eat mangoes?

In an interaction with Health and Me, Dr. Amit Chakraborty, Head and neck onco-surgeon, Mumbai, shared some simple guidelines to help oral cancer patients satisfy their mango cravings healthily.

Everyone, including oral cancer patients, eagerly waits for the mango season. After all, it is difficult to resist mangoes, right? As summer and mangoes go hand in hand, even oral cancer patients may be tempted to eat them. Mangoes are packed with vitamins, antioxidants, and natural sweetness, but they should be eaten in moderation. However, oral cancer patients and those undergoing cancer treatment often wonder whether mangoes are safe for them. Understand that the answer depends on the patient’s condition, stage of treatment, and symptoms affecting the mouth and throat.

What happens when oral cancer patients eat mangoes often?

In many cases, ripe mangoes can be safely consumed by oral cancer patients because they are soft, nutritious, and easy to swallow. However, they should have only two to three small slices of mango per day. It is not advisable to eat an entire mango. Mangoes contain vitamins A, C, and E, along with antioxidants that help support immunity and overall health. They may also provide energy to patients who struggle with appetite loss during treatment. However, oral cancer patients can suffer from mouth ulcers, pain, burning sensations, dry mouth, difficulty chewing, or sensitivity due to chemotherapy, radiation, or surgery.

In such situations, very sweet, fibrous, or slightly sour mangoes may irritate the mouth and increase discomfort. Sticky mango pulp can also sometimes remain inside the mouth, making oral hygiene important. It is necessary to avoid sour and unripe mangoes. Mango pulp, smoothies, or mashed mango can be chosen by patients who have difficulty swallowing. Again, the expert will decide the quantity. If the expert does not allow it, then it is better not to eat mangoes. Maintaining proper oral hygiene after eating is equally important to prevent infections and irritation.

Conclusion

If you have oral cancer and want to eat a mango, choose a soft, ripe mango. Moderation is key, and maintaining oral hygiene is essential. As every patient’s condition is different, follow your doctor’s advice regarding cancer treatment. All you need to do is to ensure that you do not go overboard with the fruit, as it can do more harm than good if eaten mindlessly, especially with comorbidities.

In an interview with Health and Me, Dr Sandeep Talwar, Fertility Specialist, Nova IVF Fertility, East of Kailash, Delhi, said, "The thyroid gland plays a pivotal role when it comes to controlling metabolism, energy levels, hormones, and even reproductive health. When thyroid hormone levels become imbalanced, a large number of women experience signs and symptoms such as irregular periods, difficulty with ovulation, weight changes, fatigue, or fertility problems. You will be surprised to know that one of the key nutrients needed for proper thyroid function is iodine. Yes, you heard that right! However, many women don’t know much about it and fail to include it in their daily diet. So, by adding simple iodine-rich Indian foods to everyday meals, it is possible to improve thyroid and reproductive health. A balanced diet, along with regular medical check-ups, can make a positive difference, especially for women who are planning a pregnancy."

Iodine-Rich Indian Foods For Thyroid Health

These iodine-rich foods will be beneficial for Indians in maintaining thyroid health and supporting ovulation:

1. Curd and milk are commonly available iodine-rich foods in Indian households. They also provide calcium and protein, which support overall health during fertility planning. Try to have a bowl of curd or a glass of milk for healthy thyroid function.
2. Eggs contain iodine, protein, healthy fats, and vitamin D, which support hormonal and reproductive health. Have boiled eggs or egg-based dishes for breakfast. Also, the yolk contains iodine, so eating whole eggs in moderation is fine. Make sure to consult an expert before including them in your diet.
3. Fish such as tuna, sardines, and mackerel are rich in iodine and omega-3 fatty acids, which support thyroid health and hormone balance. People who consume non-vegetarian food can include fish once a week as part of a balanced diet.
4. Green leafy vegetables and dals support hormone health. Spinach, rajma, moong dal, and chana can be included in the diet. Though they may not contain very high iodine levels, they support overall reproductive and thyroid health.
5. Iodised salt helps maintain adequate iodine intake. Be cautious and consume it in moderation, as excess salt can increase blood pressure.

Including iodine-rich foods in daily meals, exercising regularly, and undergoing regular thyroid check-ups help improve reproductive health. On World Thyroid Day, it is advised to follow a balanced and healthy diet that will help you manage disorders while also meeting basic nutrition requirements.

Sugar is bad for health, and we have heard this several times, on loop. But little do people realise that not all forms of sugar are bad for your body - some sugars are naturally occurring and might actually be the sweet treat you need. Fructose, for instance, found in fruits, is not as bad as processed sugar. But it is still important to know when to stop. In an interview with Health and Me, Dr Nimitt Nagda, Consulting Physician, Zynova Shalby Hospital, Mumbai, explained how natural sugar is different from processed sugar.

What is natural sugar?

Natural sugars present in fruits and milk tend to have nutrients and fibre, while processed sugar often adds empty calories that can harm health when consumed excessively. This article helps to explain how natural sugars impact the body differently when compared to processed sugars. Read on to know more about this and make sure to avoid excess processed sugar. So, adhere to healthy eating habits.

Sugar is a part of many foods that are eaten by people on a daily basis. However, not all sugars affect the body in the same way. Natural sugars are present in foods such as fruits, vegetables, and milk, whereas processed or added sugars are found in sweets, soft drinks, packaged snacks, bakery products, and desserts. While both types provide energy, the body handles them differently. It is the need of the hour to understand the difference between the two, as excessive intake of processed sugar is linked to obesity, diabetes, heart disease, and fatty liver disease. So, be cautious when it comes to your well-being.

Is natural sugar better?

Natural sugars are usually accompanied by fibre, vitamins, minerals, antioxidants, and water content. Fruits contain fructose, but they also provide fibre that slows down sugar absorption into the bloodstream. This helps maintain stable energy levels and prevents sudden spikes in blood sugar. Milk contains lactose along with protein and calcium, making it more nutritionally balanced. When it comes to processed sugar, it is quickly absorbed by the body because it lacks fibre and nutrients. This can lead to rapid increases in blood sugar and insulin levels. Frequent consumption of sugary foods and beverages may increase cravings, weight gain, fatigue, diabetes, obesity, and fatty liver disease. Processed sugar also contributes to inflammation, tooth decay, and unhealthy fat accumulation in the body. Moreover, natural foods are more filling, whereas processed sugary foods often encourage overeating because they do not satisfy hunger for long.

Natural sugars consumed through whole foods like fruits and milk are generally healthier because they come with essential nutrients and fibre that support overall well-being. Processed sugars, when consumed in excess, can negatively affect health and increase the risk of several chronic diseases. Choosing natural food sources and limiting added sugars can help maintain better energy levels, weight control, and long-term health. So, make sure to pay attention to your health without fail and limit processed sugar.
