Protein Bars: buying guide

When a protein bar makes sense

The Australian Institute of Sport (AIS) lists sports bars and protein supplements as Group A sports foods. Its fact sheet on mixed macronutrient products says bars are most useful when appetite is low after training, when whole foods are hard to store or prepare, or when travelling. It also notes that whole foods are usually more cost-effective and provide a wider range of nutrients, so a bar works best as a convenient extra, not your main source of protein. The International Society of Sports Nutrition suggests about 20 to 40 g of protein per serve, spread every 3 to 4 hours, which puts a 21 g bar at the lower end of a useful serve.

How to compare protein bars

  • Protein per bar and source. Fibre Boost lists whey protein isolate and milk protein isolate.
  • Fibre. Better Health Channel recommends about 30 g of fibre a day for men and 25 g for women, and notes most Australians eat around 20 to 25 g. A bar with 27 g is close to a full day's target on its own.
  • Sweeteners. Some high-protein bars use sugar alcohols, which the AIS notes can upset some people's stomachs. Fibre Boost lists steviol glycosides (from stevia).
  • Allergens. Bars often contain milk, nuts or gluten. Fibre Boost lists milk proteins and almonds and is described as gluten free.
  • Energy. Check kilojoules per bar if you are managing your weight.

Fitting a high-fibre bar into your day

If your usual diet is lower in fibre, start with one bar and drink plenty of water. Better Health Channel advises increasing fibre slowly, because a sudden jump can cause abdominal pain and wind, and fibre without enough fluid can lead to constipation. Values vary slightly between flavours, so check the wrapper of the one you buy.

Protein Bars: questions and answers

Can I eat a protein bar instead of a meal?
Occasionally, but it is not ideal as a habit. A protein bar has far less variety than a meal, and the Australian Institute of Sport notes that whole foods usually provide a wider range of nutrients and better value. Bars are most useful when appetite is low, food is hard to prepare, or you are travelling. Pair one with fruit if it has to stand in for lunch.
How many protein bars can I eat a day?
Follow the wrapper, and think about fibre as well as protein. A Fibre Boost bar lists about 27 g of fibre, close to the daily target of 25 to 30 g for adults. Better Health Channel advises increasing fibre slowly and drinking enough water, because a sudden jump can cause stomach pain and wind. Starting with one bar a day is a sensible approach.
Is a protein bar good after a workout?
It can be. The International Society of Sports Nutrition suggests around 20 to 40 g of protein per serve, spread through the day every 3 to 4 hours. A bar with about 21 g of protein sits at the lower end of that range, which suits a smaller person or a snack. Larger or older lifters may want a shake or meal as well.
Why do some protein bars upset my stomach?
Common causes are sugar alcohols, which the Australian Institute of Sport notes can cause problems for some people, and high fibre, which Better Health Channel says can cause abdominal pain and wind if you increase it too quickly. Try one bar at a time, drink water with it, and check the ingredients list for sweeteners that disagree with you.
