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.

The Diet That Changed Lionel Messi: The Five Foods That Power The Footballer At 38

Updated Dec 15, 2025 | 01:36 PM IST

SummaryDuring his India visit, Lionel Messi’s fitness has sparked curiosity, his diet shift. Once known for pizzas and sugary foods, he adopted a simple, controlled eating plan in 2014. Built around water, olive oil, whole grains, fruits and vegetables, the diet reduced inflammation, improved recovery, and helped sustain performance at 38.

Lionel Messi is here in India and is ready for his touch down in Delhi on December 15 as part of his GOAT (Greatest of All Time) Tour's India visit. Argentina's World Cup-winning captain is also set to visit Hyderabad after his visit in Delhi, for now, he has met his fans in Mumbai and Kolkata. All things said and done, what every one is always curious about is a sports person's fitness regime. The 38-year-old football star undergoes a strict fitness regime, which includes consistency, but it is not based on heavy lifting, but agility training, and a simple not-too-fancy diet.

However, his fitness journey was not traditional in any manner. In fact, during his early years, he was known for eating without much of a thought. So, what changed him? What is his secret to a fit life?

How Messi Changed His Eating Habits To Stay Fit

In 2013-14 World Cup, which was disappointing for Messi, ESPN India reported that Messi improved his performance by adapting a new diet. Charly Rexach, the then FC Barcelona's sporting director, who signed the then 13-year-old Messi to the club in 2000 on a napkin, said that Messi had previously "eaten too many pizzas".

In an interview to America TV's La Cornisa, Messi admitted about his eating habits and poor diet, which had even led to bouts of vomiting, nausea, and even lethargy. The footballer said, "I don't know what I ate, but I ate badly for many years. At 22, 23...[it was] chocolate, alfajores [South American sandwich cookies], fizzy drinks."

It was nutritionist Giuliano Poser who helped Messi make changes in 2014. His diet was nothing fancy, nothing too difficult, but it was controlled.

Five Pillars Of Messi's New Diet

Messi's new diet was based on five pillars:

  • Water
  • Olive oil
  • Whole grains
  • Fruits
  • Vegetables

Messi also shared in an interview, "Now I eat well: fish, meat, vegetables, salads. Everything is organized and taken care of. Sometimes a bit of wine, but that's not a problem."

This diet helped him reduce inflammation and recover his muscles faster. When it came to avoiding certain foods Poser stressed the importance of eating little sugar and refined flour. Poser called these two "the worst thing for the muscles". "The farther he stays away from sugars, the better. Refined flours are also a big problem as these days, it’s difficult to find uncontaminated wheat.”

Water

Studies published in the Journal of Athletic Training and Journal of Physical Therapy Science, show that dehydration increases markers of muscle damage and inflammation after exercise. Research also notes that adequate hydration supports blood flow and nutrient delivery, which are essential for muscle repair.

Olive oil

Research in Nature and the Journal of Nutritional Biochemistry highlights that extra virgin olive oil contains oleocanthal and polyphenols, compounds shown to have anti-inflammatory effects similar to mild anti-inflammatory drugs, helping reduce muscle soreness and inflammation.

Whole grains

According to studies in the American Journal of Clinical Nutrition, whole-grain intake is associated with lower levels of C-reactive protein, a key marker of inflammation. Their complex carbohydrates and magnesium content support muscle function and recovery after physical activity.

Fruits

Research published in Nutrients and Sports Medicine shows that antioxidant-rich fruits like berries and citrus help reduce oxidative stress caused by exercise, which can otherwise delay muscle recovery and increase inflammation.

Vegetables

Large observational studies, including reports in The BMJ, link high vegetable intake with reduced systemic inflammation. Their vitamins, minerals, and phytochemicals support immune response and tissue repair, aiding post-exercise muscle recovery.

What Does Messi's Workout Regime Look Like? 3s Of Messi's Fitness

As per reports, Messi's training is not as rigorous as players like Neymar and Cristiano Ronaldo, but it does not mean that there is not consistency. In fact, his primary training focuses on three factors:

  • Speed
  • Strength
  • Stretching

The footballer’s fitness does not come from heavy weightlifting. Instead, it is built on a balanced routine that focuses on strength training, agility, speed, extensive stretching, and overall muscle health. His workouts include short, explosive sprints, bounding drills like hurdle hops and pillar skips, all aimed at keeping his body sharp, responsive, and match-ready.

Taking Mounjaro For Weight Loss? Doctor Warns Why Protein Intake Is Non-Negotiable

Updated Dec 15, 2025 | 03:00 AM IST

SummaryTaking Mounjaro for weight loss can sharply reduce appetite, but doctors say that eating too little protein may cost you muscle, energy, and metabolic health. An expert explains why protein intake becomes critical on Mounjaro, how much you should aim for each day, and the hidden risks of focusing only on the scale.

Mounjaro has reshaped weight-loss journeys by powerfully reducing appetite, but doctors are now flagging an important concern. Dr Hasia, who recently addressed this on her Instagram, explained that when food intake drops sharply on Mounjaro, protein intake often falls with it. The result is weight loss that may include muscle, not just fat.

How Mounjaro’s Appetite Suppression Affects Muscle

Mounjaro works by influencing hormones that control hunger and blood sugar, helping people feel full faster and eat less. Dr Hasia notes that while this is effective for fat loss, it can quietly lead to muscle breakdown if protein is not prioritised. When protein is low, the body turns to muscle tissue for essential amino acids, weakening the body over time.

The Protein Rule Dr Hasia Recommends on Mounjaro

In her Instagram post, Dr Hasia shared a simple guideline for those using Mounjaro. Aim for 1.0 to 1.5 grams of protein per kilogram of body weight each day. For example, a person weighing 70 kilograms should target roughly 70 to 100 grams of protein daily. This amount supports muscle preservation even when overall calories are reduced.

Why Protein on Mounjaro Protects Metabolism

Muscle plays a major role in keeping metabolism active. Dr Hasia explains that losing muscle on Mounjaro can slow metabolic rate, making long-term weight maintenance harder. Adequate protein helps preserve lean mass, which keeps calorie burning steady and reduces the risk of fatigue during weight loss.

How Protein on Mounjaro Supports Skin and Strength

Rapid weight loss can sometimes lead to sagging skin and weakness. According to Dr Hasia, protein supports collagen production, which helps maintain skin firmness. It also preserves strength, making day-to-day activities easier and reducing the sense of physical depletion some people report while on Mounjaro.

Easy Protein Meals to Tolerate on Mounjaro

Because appetite is often low on Mounjaro, Dr Hasia suggests choosing protein foods that feel light and manageable. Greek yogurt with chia seeds works well for breakfast. Smoothies with almond milk and a scoop of whey or collagen are often easier than solid meals. Lunch or dinner can include grilled salmon, chicken, eggs, or tofu with vegetables and healthy fats.

Smart Protein Snacks While Using Mounjaro

On days when full meals feel difficult, Dr Hasia recommends small protein-rich snacks. Boiled eggs, edamame, tuna cups, cottage cheese, or a simple protein bar can help meet daily needs without overwhelming the stomach. These options make it easier to stay consistent.

How to Space Protein Intake on Mounjaro

Dr Hasia also highlights the importance of spreading protein throughout the day. Instead of eating it all at once, aiming for 20 to 30 grams per meal allows better absorption and ongoing muscle support. On Mounjaro, consistency matters more than portion size.

Protein, as Dr Hasia reminds her followers, is not an extra on Mounjaro. It is a foundation. Protecting muscle now helps protect metabolism

Vegan Children Are Shorter And Skinnier Than Meat-Eaters, Nutritionists Raise Concern

Updated Dec 13, 2025 | 08:00 PM IST

SummaryNew research shows vegan and vegetarian children may be shorter and lighter than meat-eaters due to lower intake of key nutrients like B12, calcium, and zinc, though plant-based diets also support heart health. Keep reading for more details.

Children following vegan and vegetarian diets may be missing key nutrients, according to a group of international researchers who shared their findings on Friday.

Plant-based eating has long been linked with lower risks of heart disease and stronger immunity. Yet a new peer-reviewed study, the largest of its kind, analysed 48,000 children and adolescents and found that vegetarian kids were consuming fewer calories, less protein and fat, and lower amounts of important nutrients like zinc and vitamin B12, which supports the nervous system. Vegan children showed similar patterns, with a particularly noticeable lack of calcium, which is vital for bone health.

Vegan Children Are Shorter And Skinnier Than Meat-Eaters

“Vitamin B12 rarely reaches adequate levels without supplementation or fortified foods, and calcium, iodine, and zinc are often at the lower end of recommended intake, making them critical nutrients for kids on plant-based diets,” said Dr. Jeannette Beasley, associate professor at New York University and one of the study’s authors.

The research reviewed 59 studies across 18 countries, comparing nutritional outcomes among 7,280 vegetarians, 1,289 vegans, and 40,059 children who ate both plants and meat (omnivores).

A Boost To Heart Health

While the study highlighted potential nutrient gaps in plant-based diets, it also showed benefits. Vegetarian children consumed more fibre, iron, folate, and vitamin C than omnivores, and both vegan and vegetarian children showed healthier hearts.

They had lower levels of LDL cholesterol, the “bad” cholesterol that can clog arteries and increase the risk of heart attacks and strokes later in life.

“The more animal products replace whole plant foods in the diet, the worse cardiovascular health tends to be,” said Dr. Dana Hunnes, senior dietitian at Ronald Reagan UCLA Medical Center, who was not involved in the study, as per The Independent.

Vegan and vegetarian children were also shorter and had a lower body mass index than meat-eaters, which may reduce the risk of obesity and diabetes—conditions that can further impact heart health.

Small Snacks, Big Difference

Although plant-based diets may leave gaps in nutrients like B12 or zinc, careful planning can help children meet their needs.

While animal products are naturally higher in zinc, lentils, pumpkin seeds, and cashews are excellent plant-based sources, with cashews providing nearly eight grams of zinc per cup. These can be eaten as snacks, added to soups, or blended into smoothies.

For vitamin B12, plant-based children can include seaweed or shiitake mushrooms in their diet. A 100-gram serving of shiitake mushrooms contains about 5.6 micrograms of B12.

According to Stanford Medicine, children should get between three and 11 milligrams of zinc depending on age, and between 0.9 and 2.4 micrograms of vitamin B12.

“Our findings suggest a balanced approach is key, with families ensuring kids get enough of vitamin B12, calcium, iodine, iron, and zinc to grow and thrive,” said Dr. Wolfgang Marx, co-author and senior research fellow at Deakin University in Australia.
