5 nutritionist-approved protein bars

diet nutrition protein tips and advice

A stroll down the health food aisle has become a choice minefield. Protein powders, functional foods and bars line the shelves, and it seems every product from cereal to yoghurt and chips is boosted with extra protein.

As an avid gym goer and adventurer, I’ve tried many ways to maintain energy and refuel throughout the day. Here I share my top five protein bar picks, explain what protein is, and how to get enough of it.

Ready to level up your protein game?

What is protein?

Although all the macronutrients are essential, the power of protein continues to be having a moment.

Of the three macronutrients that gives us energy, protein is essential for building and repairing tissues (like muscles, hair, and nails), making hormones, and supporting immune function. The king hunger-squasher, protein is also important for those trying to lose weight; if you satisfy your protein appetite, you’re less likely to eat excess calories.

Unlike its macro cousins, carbohydrates and fats, protein isn’t stored in the body. There is no protein reserve. We have to eat protein rich foods each day. Think beans, chickpeas, meat, fish, nuts, yoghurt, cheese, tofu, and eggs.

How much do we need?

The Australian Dietary Guidelines recommend 2.5 serves of protein per day for women and three for men. For women, this is the equivalent to a can of tuna, one egg and a 200g tub of yoghurt. According to the most recent National Nutrition Survey, 99 percent of Australians obtain sufficient protein from foods alone. But, if you’re very active, pregnant, vegetarian or vegan, training regularly or have a physically demanding job, consider boosting your protein.

If you’re not getting enough protein in your diet, up the protein-rich foods or choose a good quality protein powder or protein bar to supplement.

Don’t overdo it though (like by smashing protein shakes and bars at every meal) because a very high protein diet can strain the kidneys and liver. It can also prompt excessive calcium loss, which can increase osteoporosis risk.

I train hard, bike ride, and hike regularly and find protein bars are the perfect way to maintain energy without eating a whole meal. I wouldn’t eat them every day, perhaps two bars per week, preferring to get my protein from other sources, like nuts, eggs, cottage cheese and yoghurt, small amounts of beef, and fish.

What to look for in a bar

1.Does it contain enough or too much protein? The body can only absorb around 25-30g of protein in one go, any more than this is a waste. If a bar has too much protein, try eating half, waiting a few hours, then have the rest.

Look for bars that contain between 7-15g of protein per serve.

2. Watch out for artificial sweeteners. To reduce sugar content, many protein bars contain artificial sweeteners. Look out for these ones: Sucralose (955), Aspartame (951) or Saccharin (954). Artificial sweeteners are just that – artificial and unnecessary.

The best bars use natural sweeteners like dates, honey, or even stevia.

3. Avoid genetically modified soy, artificial flavours, thickeners and artificial colourings. Some of these additives can cause stomach upset and bloating or unknown long-term effects.

4. Does it contain too much energy? The average Australian needs 8700kJ per day. If a bar provides a fair portion of this, and you’re also eating 3 meals + extra snacks, you could easily surpass your energy needs - a sure-fire way to gain weight.

5. Type of protein Animal protein, like whey contains the full complement of essential amino acids (building blocks) and is easily assimilated in the body, so is typically the go-to protein for most.
However, as more Aussies lean into plant-based living, protein from plants is on the rise. As all plants are deficient in one or more amino acids, ideally your protein bar has a mix of plants (like rice and pea) to obtain the full complement of amino acids. Don’t worry too much though – as long as you’re getting the full range of amino acids throughout the day from a variety of plant foods, the body will sort it out.
