We know the importance of staying hydrated, especially in hot weather. But even for something as simple as a drink of water, conflicting advice and urban myths abound.

Is cold water really bad for your health? What about hot water from the tap? And what is “raw water”? Let’s dive in and find out.

Myth 1: Cold water is bad for you

Some recent TikToks have suggested cold water causes health problems by somehow “contracting blood vessels” and “restricting digestion”. There is little evidence for this.

While a 2001 study found 51 out of 669 women tested (7.6%) got a headache after drinking cold water, most of them already suffered from migraines and the work hasn’t been repeated since.

Cold drinks were shown to cause discomfort in people with achalasia (a rare swallowing disorder) in 2012 but the study only had 12 participants.

For most people, the temperature you drink your water is down to personal preference and circumstances. Cold water after exercise in summer or hot water to relax in winter won’t make any difference to your overall health.

Myth 2: You shouldn’t drink hot tap water

This belief has a grain of scientific truth behind it. Hot water is generally a better solvent than cold water, so may dissolve metals and minerals from pipes better. Hot water is also often stored in tanks and may be heated and cooled many times. Bacteria and other disease-causing microorganisms tend to grow better in warm water and can build up over time.

It’s better to fill your cup from the cold tap and get hot water for drinks from the kettle.

Myth 3: Bottled water is better

While bottled water might be safer in certain parts of the world due to pollution of source water, there is no real advantage to drinking bottled water in Australia and similar countries.

According to University of Queensland researchers, bottled water is not safer than tap water. It may even be tap water. Most people can’t tell the difference either. Bottled water usually costs (substantially) more than turning on the tap and is worse for the environment.

What about lead in tap water? This problem hit the headlines after a public health emergency in Flint, Michigan, in the United States. But Flint used lead pipes with a corrosion inhibitor (in this case orthophosphate) to keep lead from dissolving. Then the city switched water sources to one without a corrosion inhibitor. Lead levels rose and a public emergency was declared.

Fortunately, lead pipes haven’t been used in Australia since the 1930s. While lead might be present in some old plumbing products, it is unlikely to cause problems.

Myth 4: Raw water is naturally healthier

Some people bypass bottled and tap water, going straight to the source.

The “raw water” trend emerged a few years ago, encouraging people to drink from rivers, streams and lakes. There is even a website to help you find a local source.

Supporters say our ancestors drank spring water, so we should, too. However, our ancestors also often died from dysentery and cholera and their life expectancy was low.

While it is true even highly treated drinking water can contain low levels of things like microplastics, unless you live somewhere very remote, the risks of drinking untreated water are far higher as it is more likely to contain pollutants from the surrounding area.

Myth 5: It’s OK to drink directly from hoses

Tempting as it may be, it’s probably best not to drink from the hose when watering the plants. Water might have sat in there, in the warm sun for weeks or more potentially leading to bacterial buildup.

Similarly, while drinking water fountains are generally perfectly safe to use, they can contain a variety of bacteria. It’s useful (though not essential) to run them for a few seconds before you start to drink so as to get fresh water through the system rather than what might have been sat there for a while.

We are fortunate to be able to take safe drinking water for granted. Billions of people around the world are not so lucky.

So whether you like it hot or cold, or somewhere in between, feel free to enjoy a glass of water this summer.

Just don’t drink it from the hose.

Does it seem like most vegetables you serve your children end up left on the plate, or worse, strewn across the floor? But mention dessert, and your fruit skewers are polished off in an instant.

Or maybe the carrot and cucumber sticks keep coming home in your child’s lunchbox untouched, yet the orange slices are nowhere to be seen.

If you’re facing these struggles with your child, you’re not alone. Many children prefer fruit to vegetables.

So if your child eats lots of fruit but minimal or no vegetables, is that OK? And how can you get them to eat more veggies?

Children have an innate preference for fruit

The Australian Dietary Guidelines’ recommended daily intakes for vegetables and fruit depend on a child’s age.

Consumption among Australian children falls well below recommendations. Around 62.6% of children aged over two meet the recommended daily fruit intake, but only 9% meet the recommended vegetable intake.

This is not surprising given children have a natural preference for fruit. At least in part, this is due to its sweetness and texture, whether crispy, crunchy or juicy. The texture of fruit has been linked to a positive sensory experience among children.

Vegetables, on the other hand, are more of an acquired taste, and certain types, such as cruciferous vegetables, can be perceived by children as bitter.

The reason children often prefer fruit over vegetables could also be related to the parents’ preferences. Some research has even suggested we develop food preferences before birth based on what our mother consumes during pregnancy.

Balance is key

So, a preference for fruit is common. But is it OK if your child eats lots of fruit but little to no vegetables? This is a question we, as dietitians, get asked regularly.

You might be thinking, at least my child is eating fruit. They could be eating no veggies and no fruit. This is true. But while it’s great your child loves fruit, vegetables are just as important as part of a balanced eating pattern.

Vegetables provide us with energy, essential vitamins and minerals, as well as water and fibre, which help keep our bowels regular. They also support a strong immune system.

If your child is only eating fruit, they are missing some essential nutrients. But the same is true if they are eating only veggies.

Fruit likewise provides the body with a variety of essential vitamins and minerals, as well as phytochemicals, which can help reduce inflammation.

Evidence shows healthy consumption of fruit and vegetables protects against chronic diseases including high blood pressure, heart disease and stroke.

Consumed together, fruit and vegetables in a variety of colours provide different nutrients we need, some of which we can’t get from other foods. We should encourage kids to eat a “rainbow” of fruit and vegetables each day to support their growth and development.

What if my child eats too much fruit?

If your child is eating slightly more fruit than what’s recommended each day, it’s not usually a problem.

Fruit contains natural sugar which is good for you. But too much of a good thing, even if it’s natural, can create problems. Fruit also contains virtually no fat and very little to no protein, both essential for a growing child.

When overindulging in fruit starts to displace other food groups such as vegetables, dairy products and meat, that’s when things can get tricky.

6 tips to get your kids to love vegetables

1. Get them involved

Take your child with you when you go shopping. Let them choose new vegetables. See if you can find vegetables even you haven’t tried, so you’re both having a new experience. Then ask them to help you with preparing or cooking the vegetables using a recipe you have chosen together. This will expose your child to veggies in a positive way and encourage them to eat more.

2. Sensory learning

Try to expose your child to vegetables rather than hiding them. Kids are more likely to eat veggies when they see, smell and feel them. This is called sensory learning.

3. Have fun with food

Use colourful vegetables of different sizes and textures. Make them fun by creating scenes or faces on your child’s plate. Add edible flowers or mint for decoration. You can even serve this with a side of veggie-based dip such as hummus or guacamole for some bonus healthy fats.

4. Teach them to grow their own

Teach your child how to grow their own vegetables. Evidence shows kids are more inclined to try the food they have helped and watched grow. You don’t need to have a big backyard to do this. A windowsill with a pot plant is a perfect start.

5. Lead by example

Your child learns from you, and your eating habits will influence theirs. Ensure they see you eating and enjoying veggies, whether in meals or as snacks.

6. Practise persistence

If your child refuses a particular vegetable once, don’t give up. It can take many attempts to encourage children to try a new food.
