Toddler milk is popular and becoming more so. Just over a third of Australian toddlers drink it. Parents spend hundreds of millions of dollars on it globally. Around the world, toddler milk makes up nearly half of total formula milk sales, with a 200% growth since 2005. Growth is expected to continue.

We’re concerned about the growing popularity of toddler milk – about its nutritional content, cost, how it’s marketed, and about the impact on the health and feeding of young children. Some of us voiced our concerns on the ABC’s 7.30 program recently.

But what’s in toddler milk? How does it compare to cow’s milk? How did it become so popular?

What is toddler milk? Is it healthy?

Toddler milk is marketed as appropriate for children aged one to three years. This ultra-processed food contains:

• skim milk powder (cow, soy or goat)
• vegetable oil
• sugars (including added sugars)
• emulsifiers (to help bind the ingredients and improve the texture)

• added vitamins and minerals.

Toddler milk is usually lower in calcium and protein, and higher in sugar and calories than regular cow’s milk. Depending on the brand, a serve of toddler milk can contain as much sugar as a soft drink.

Even though toddler milks have added vitamins and minerals, these are found in and better absorbed from regular foods and breastmilk. Toddlers do not need the level of nutrients found in these products if they are eating a varied diet.

Global health authorities, including the World Health Organization (WHO), and Australia’s National Health and Medical Research Council, do not recommend toddler milk for healthy toddlers.

Some children with specific metabolic or dietary medical problems might need tailored alternatives to cow’s milk. However, these products generally are not toddler milks and would be a specific product prescribed by a health-care provider.

Toddler milk is also up to four to five times more expensive than regular cow’s milk. “Premium” toddler milk (the same product, with higher levels of vitamins and minerals) is more expensive.

With the cost-of-living crisis, this means families might choose to go without other essentials to afford toddler milk.

How toddler milk was invented

Toddler milk was created so infant formula companies could get around rules preventing them from advertising their infant formula.

When manufacturers claim benefits of their toddler milk, many parents assume these claimed benefits apply to infant formula (known as cross-promotion). In other words, marketing toddler milks also boosts interest in their infant formula.

Manufacturers also create brand loyalty and recognition by making the labels of their toddler milk look similar to their infant formula. For parents who used infant formula, toddler milk is positioned as the next stage in feeding.

How toddler milk became so popular

Toddler milk is heavily marketed. Parents are told toddler milk is healthy and provides extra nutrition. Marketing tells parents it will benefit their child’s growth and development, their brain function and their immune system.

Toddler milk is also presented as a solution to fussy eating, which is common in toddlers.

However, regularly drinking toddler milk could increase the risk of fussiness as it reduces opportunities for toddlers to try new foods. It’s also sweet, needs no chewing, and essentially displaces energy and nutrients that whole foods provide.

Growing concern

The WHO, along with public health academics, has been raising concerns about the marketing of toddler milk for years.

In Australia, moves to curb how toddler milk is promoted have gone nowhere. Toddler milk is in a category of foods that are allowed to be fortified (to have vitamins and minerals added), with no marketing restrictions. The Australian Competition & Consumer Commission also has concerns about the rise of toddler milk marketing. Despite this, there is no change in how it’s regulated.

This is in contrast to voluntary marketing restrictions in Australia for infant formula.

What needs to happen?

There is enough evidence to show the marketing of commercial milk formula, including toddler milk, influences parents and undermines child health.

So governments need to act to protect parents from this marketing, and to put child health over profits.

Public health authorities and advocates, including us, are calling for the restriction of marketing (not selling) of all formula products for infants and toddlers from birth through to age three years.

Ideally, this would be mandatory, government-enforced marketing restrictions as opposed to industry self-regulation in place currently for infant formulas.

We musn’t blame parents

Toddlers are eating more processed foods (including toddler milk) than ever because time-poor parents are seeking a convenient option to ensure their child is getting adequate nutrition.

Formula manufacturers have used this information, and created a demand for an unnecessary product.

Parents want to do the best for their toddlers, but they need to know the marketing behind toddler milks is misleading.

Toddler milk is an unnecessary, unhealthy, expensive product. Toddlers just need whole foods and breastmilk, and/or cow’s milk or a non-dairy, milk alternative.

If parents are worried about their child’s eating, they should see a health-care professional.

Humans have long been searching for a “magic elixir” to make us smarter, and improve our focus and memory. This includes traditional Chinese medicine used thousands of years ago to improve cognitive function.

Now we have nootropics, also known as smart drugs, brain boosters or cognitive enhancers.

You can buy these gummies, chewing gums, pills and skin patches online, or from supermarkets, pharmacies or petrol stations. You don’t need a prescription or to consult a health professional.

But do nootropics actually boost your brain? Here’s what the science says.

What are nootropics and how do they work?

Romanian psychologist and chemist Cornelius E. Giurgea coined the term nootropics in the early 1970s to describe compounds that may boost memory and learning. The term comes from the Greek words nӧos (thinking) and tropein (guide).

Nootropics may work in the brain by improving transmission of signals between nerve cells, maintaining the health of nerve cells, and helping in energy production. Some nootropics have antioxidant properties and may reduce damage to nerve cells in the brain caused by the accumulation of free radicals.

But how safe and effective are they? Let’s look at four of the most widely used nootropics.

1. Caffeine

You might be surprised to know caffeine is a nootropic. No wonder so many of us start our day with a coffee. It stimulates our nervous system.

Caffeine is rapidly absorbed into the blood and distributed in nearly all human tissues. This includes the brain where it increases our alertness, reaction time and mood, and we feel as if we have more energy.

For caffeine to have these effects, you need to consume 32-300 milligrams in a single dose. That’s equivalent to around two espressos (for the 300mg dose). So, why the wide range? Genetic variations in a particular gene (the CYP1A2 gene) can affect how fast you metabolise caffeine. So this can explain why some people need more caffeine than others to recognise any neurostimulant effect.

Unfortunately too much caffeine can lead to anxiety-like symptoms and panic attacks, sleep disturbances, hallucinations, gut disturbances and heart problems.

So it’s recommended adults drink no more than 400mg caffeine a day, the equivalent of up to three espressos.

2. L-theanine

L-theanine comes as a supplement, chewing gum or in a beverage. It’s also the most common amino acid in green tea.

Consuming L-theanine as a supplement may increase production of alpha waves in the brain. These are associated with increased alertness and perception of calmness.

However, it’s effect on cognitive functioning is still unclear. Various studies including those comparing a single dose with a daily dose for several weeks, and in different populations, show different outcomes.

But taking L-theanine with caffeine as a supplement improved cognitive performance and alertness in one study. Young adults who consumed L-theanine (97mg) plus caffeine (40mg) could more accurately switch between tasks after a single dose, and said they were more alert.

Another study of people who took L-theanine with caffeine at similar doses to the study above found improvements in several cognitive outcomes, including being less susceptible to distraction.

Although pure L-theanine is well tolerated, there are still relatively few human trials to show it works or is safe over a prolonged period of time. Larger and longer studies examining the optimal dose are also needed.

3. Ashwaghanda

Ashwaghanda is a plant extract commonly used in Indian Ayurvedic medicine for improving memory and cognitive function.

In one study, 225-400mg daily for 30 days improved cognitive performance in healthy males. There were significant improvements in cognitive flexibility (the ability to switch tasks), visual memory (recalling an image), reaction time (response to a stimulus) and executive functioning (recognising rules and categories, and managing rapid decision making).

There are similar effects in older adults with mild cognitive impairment.

But we should be cautious about results from studies using Ashwaghanda supplements; the studies are relatively small and only treated participants for a short time.

4. Creatine

Creatine is an organic compound involved in how the body generates energy and is used as a sports supplement. But it also has cognitive effects.

In a review of available evidence, healthy adults aged 66-76 who took creatine supplements had improved short-term memory.

Long-term supplementation may also have benefits. In another study, people with fatigue after COVID took 4g a day of creatine for six months and reported they were better able to concentrate, and were less fatigued. Creatine may reduce brain inflammation and oxidative stress, to improve cognitive performance and reduce fatigue.

Side effects of creatine supplements in studies are rarely reported. But they include weight gain, gastrointestinal upset and changes in the liver and kidneys.

Where to now?

There is good evidence for brain boosting effects of caffeine and creatine. But the jury is still out on the efficacy, optimal dose and safety of most other nootropics.

So until we have more evidence, consult your health professional before taking a nootropic.

But drinking your daily coffee isn’t likely to do much harm. Thank goodness, because for some of us, it is a magic elixir.
