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.

US Vice President JD Vance has credited his weight loss to Health and Human Services Secretary Robert Kennedy Jr.’s advice to eat sauerkraut and protein.

Speaking at the first official White House press briefing since July 23, Vance said Kennedy’s advice helped him begin his weight-loss journey around Lent in February.

“So, when you're the vice president of the United States and one of the first questions at a press conference in the White House is how much weight you've lost, you must have gotten very fat,” Vance said, according to Fox News.

What Did Robert Kennedy Jr. Advise JD Vance?

Vance said he called Kennedy and told him he was thinking of giving up sugar.

“Bobby Kennedy says, ‘No, no, no, no, I've got something that's way better than that and way more intense.’ And basically ... I eat a lot of high protein stuff, and I eat a lot of sauerkraut. And let's just say that if that was Fat Tuesday, Fat Wednesday never came,” Vance said.

“So, my advice to you is that if you want to lose weight, call Bobby Kennedy. And if you want to enjoy what you eat, do not call Bobby Kennedy.”

At the press briefing, Vance also addressed several other topics, including the Iran war, oil and gas prices, inflation and Republican messaging ahead of the midterms.

What Is Sauerkraut?

Sauerkraut is traditionally a fermented food made from shredded cabbage and salt.

Fermentation occurs through Lactobacillus bacteria that naturally occur on the leaves of the vegetable. These bacteria feed on the sugar in the cabbage.

To make sauerkraut, the cabbage is submerged in a salty liquid created by combining it with its own juice. The bacteria consume the sugar and produce lactic acid, which helps preserve the food, prevent the growth of harmful organisms and create an environment where beneficial bacteria can grow.

The simple dish contains beneficial bacteria that can support gut health and overall well-being. It is also known to aid digestion and support immunity.

Health Benefits Of Sauerkraut

A 2025 study published in Applied and Environmental Microbiology suggested that fermented cabbage could help protect the gut, an essential part of overall health.

Researchers from the University of California, Davis, found that sauerkraut helped maintain the integrity of intestinal cells, while raw cabbage and brine did not.

Studies have also suggested that sauerkraut may have:

• Anti-inflammatory effects
• A role in regulating immune function
• Antioxidant properties
• Potential anticancer properties.

How Does Protein Help With Weight Loss?

During weight loss, protein can help preserve muscle and increase satiety. For muscle gain, however, protein needs to be paired with resistance training.

Dr Amit Prakash Singh, Consultant - Internal Medicine at CK Birla Hospital, Delhi, told HealthandMe that protein can help preserve muscle and improve satiety during weight loss, while muscle gain requires protein along with resistance training.

“Simply increasing protein without appropriate calories and exercise will not build muscle.”

How Much Protein Do You Need?

Most healthy adults need around 0.8 g/kg of protein per day. Regular exercisers and strength trainers may need 1.2–1.6 g/kg/day, depending on their goals, activity level, diet, age and health.

Low protein intake can contribute to muscle loss, weakness, poor recovery and slower healing. Protein supplements are usually unnecessary when the diet already provides enough protein.

We often think about longevity as a number: 80, 90, perhaps even 100. But the more meaningful question is not simply how long we live but how well we live while we are here.

Nutrition has an important role in answering these questions. And the good news is that a longevity diet does not have to be exotic, expensive, or built around a shelf of supplements. Much of what supports healthy ageing is already familiar to kitchens across India and around the world.

The secret is less about a single “superfood” and more about the pattern on our plate.

Think Beyond Calories

For many years, nutrition conversations centered on calories, weight and individual nutrients. These remain relevant, but longevity requires a broader view.

A healthy diet should provide adequate protein, fibre, vitamins, minerals and healthy fats while keeping excess salt, free sugars and unhealthy fats in check. The World Health Organization describes adequacy, balance, moderation and diversity as the basic principles of a healthy diet.

In practical terms, this means making minimally processed foods the foundation of everyday eating.

Build A Colorful, Proportionate Plate

A useful starting point is surprisingly simple: make plants the stars of every meal.

Vegetables, leafy greens, fruits, pulses, whole grains, nuts and seeds provide a combination of fibre and micronutrients that is difficult to replicate through processed foods or supplements alone. But the key, though, is the proportion: the ¼-¼-½ rule. Imagine your plate as a pie chart: a quarter goes to carbohydrates, a quarter to protein, and an entire half has to go to vegetables.

An Indian plate is generally fresh and unprocessed (which is the good part), but also heavily unbalanced (which is the bad part). Our plates usually cede place to excess carbohydrates in lieu of protein or vegetables. Imagine a pile of buttered rotis with watery dal or a mountain of rice with rasam, which are the usual staples at many Indian homes, and you will understand this proportionality problem.

Cuisine can change across states. The nutritional principle does not. The WHO recommends at least 400 grams of fruits and vegetables a day, while also encouraging whole grains, pulses and nuts. Half the plate should be strictly reserved for salads/veg rich sabzi / poriyals and such, while carbs are strictly confined to a quarter. No more than a cup of rice, no more than two rotis!

Do Not Forget Protein

The final quarter in the plate belongs to protein. One of the less appreciated aspects of healthy ageing is the preservation of muscle, and muscle needs protein. India is a chronically protein-deficient nation. Multiple national surveys have shown the protein intake of the population to be inadequate across the length and breadth of the nation.

As we grow older, maintaining adequate protein intake becomes increasingly important, particularly when combined with regular resistance or strength-building exercise. Protein does not always have to mean eating large quantities of meat.

For vegetarians, dal, rajma, chana, soy, peas, milk, curd, paneer, nuts, and seeds can all contribute. For those who eat non-vegetarian foods, eggs, fish, poultry and lean meats can be included according to personal preferences and cultural practices.

Portion Your Carbs, But Also Choose The Grain

Carbohydrates are not the enemy if we eat them in the right quantity, particularly if they are less processed.

Replacing a diet dominated by refined grains and highly processed foods with more whole grains, millets, vegetables, fruits and pulses can increase fibre and improve the overall nutritional quality of the diet. They also reduce sugar spikes in diabetics and people with prediabetes, who constitute 50% of the entire population in some Indian states!

Rice, bread, or potatoes need not disappear from the table. We just need to put them in context alongside vegetables, protein and healthy fats rather than allowing refined carbohydrates to dominate every meal.

Interestingly, traditional Indian cuisine already has the ingredients. We just need to make the effort to find the balance. A bowl of rice with paneer, veg salad and thick dahi, for example, is very different nutritionally from a meal built around refined carbohydrates alone.

Fats: Quality Matters

Healthy ageing does not require a completely fat-free diet. Fat is an essential nutrient. What matters is the type and amount. Unchecked oil consumption along with refined sugar intake is fuelling the obesity epidemic in India today. No more than three spoons of oil in a day, and we should stick to less inflammatory filtered groundnut and mustard oils while we are at it!

The rest of the healthy fats can come from sources such as nuts, seeds, dahi, milk and lean meat such as fish and chicken. Foods high in saturated and trans fats, along with frequent deep-fried and highly processed foods, should be avoided. Read: biscuits, cookies, burgers, fried food, refined seed oils and vanaspati.

Even familiar foods such as ghee need not become either a hero or a villain. It is better to think about overall dietary pattern and portion size than to label individual foods as universally “good” or “bad”.

The Quiet Problem: Salt, Sugar And Ultra-processed Food

The foods that quietly accumulate in our diets can matter as much as what we consciously add.

Sugary beverages, packaged snacks, bakery products, processed meats and highly salted foods can contribute substantial amounts of sugar, sodium, unhealthy fats and calories without providing comparable nutritional value.

The WHO recommends limiting free sugars to less than 10% of daily energy intake, with further reduction offering additional health benefits, and keeping salt intake below 5 grams a day for adults.

This does not mean giving up birthday cake, festival sweets or an occasional restaurant meal. Longevity is less about eating perfectly every single time and more about making a healthier choice most of the time.

Perhaps The Most Important Ingredient Is Consistency

There is no single longevity food. No turmeric latte, berry, seed, oil, supplement or superfood can compensate for a dietary pattern that is consistently poor. Likewise, one celebratory meal does not undo years of healthy eating.

The most sustainable approach is one that fits into real life: seasonal vegetables, locally available fruits, pulses, whole grains, nuts and seeds; appropriate protein; sensible portions; plenty of water; and fewer foods that are heavily processed, excessively salty or sugary.

For an Indian audience, this is encouraging because our culinary traditions already offer enormous diversity from millets and dals to greens, fermented foods, curd, spices, nuts and seasonal produce. For an international audience, the same philosophy can be adapted to their own local foods and cultures.

The longevity plate, therefore, is not a prescription for one perfect meal. It is a way of eating.

Eat a little closer to nature. Add more variety. Protect muscle. Choose quality over processing. Keep portions sensible. And make these choices consistently. Because the goal of nutrition is not simply to add years to life. It is to help us add strength, independence and vitality to those years.

A particular brand of granola marketed for breastfeeding mothers has been recalled in the US over concerns that it could be contaminated with Salmonella.

The US Food and Drug Administration (FDA) said The Hampton Grocer, Inc. recalled around 8-ounce packages of its Lacnola Lactation Granola after being alerted by an ingredient supplier about possible contamination. No illnesses linked to the granola have been reported so far.

Popular Granola For New Mothers Recalled

The issue traces back to organic moringa powder, an ingredient that is used in the recalled granola. The Hampton Grocer was notified by its supplier, Food to Live, that a sample of its Organic SuperGreens Powder Mix had tested positive for Salmonella. The same supplier’s moringa powder is used in the affected Lacnola batches.

US FDA said that neither the finished Lacnola granola nor the specific moringa powder used in it had tested positive for Salmonella at the time of the recall. The exact source of possible contamination remains under investigation. The company has suspended production while the investigation continues.

Which Products Are Affected?

The recall applies specifically to 8-ounce pink stand-up pouches of Lacnola Lactation Granola with UPC 850035324554. Consumers should check the lot information printed on the back of the package. The affected products are:

• Lot HGLC-102125 | Expiration: October 21, 2026
• Lot HGLC-021326 | Expiration: February 13, 2027

The granola was sold nationwide through mail orders on The Hampton Grocer’s website and through Amazon between October 21, 2025 and August 12, 2026.

What Is The Risk From Salmonella?

Salmonella is a kind of bacteria that can cause an infection called salmonellosis. It causes food-borne illnesses. In otherwise healthy people, this infection can commonly lead to symptoms like diarrhoea, fever, nausea, vomiting and stomach or abdominal pain. Symptoms can sometimes become severe, particularly when the infection spreads beyond the intestine.

The FDA notes that young children, older people and those with weak immunity are at greater risk of serious illness if they get infected by salmonella.

For breastfeeding mothers, the recall is particularly concerning because the product is specifically marketed as a lactation granola. However, the recall does not mean that Salmonella from contaminated food automatically passes into breast milk.

The immediate concern is the mother’s exposure to the contaminated granola and the possibility of foodborne illness. This could cause the mother as well as the newborn to get sick.

What Should You Do If You Have The Granola?

If you have Lacnola Lactation Granola at home, check the lot code and expiration date before eating it. If it matches either recalled lot, the FDA advises consumers to dispose of the product and contact the place of purchase for a refund.

The FDA says no illnesses have been reported in connection with the recalled granola to date. The recall is a precautionary measure while authorities and the company investigate the contamination.
