The Ultimate Guide To Using Protein Powder

protein powder

Protein powder is everywhere. It’s in our social media feeds, on our supermarket shelves and there are countless brands, types and formulations. Understandably it can be a little overwhelming.

So, we thought we’d break it down into bite sized pieces of information to help clarify some common question about protein and protein powder.

Do you need it?
We love protein powder for its ease and convenience. It’s an efficient way to get protein into one’s diet. It’s especially great for those who are short for time, struggle to consume adequate protein or want to stimulate muscle protein synthesis.

In saying that, it’s definitely not essential for optimum health. We encourage focusing on whole food sources of protein first and foremost. When we eat protein from whole food sources we get the added benefits of other nutrients and minerals. Plant based protein sources are also rich in fibre which we know is super important for our gut health.

There are so many delicious sources of animal and plant-based proteins (with the added bonus that they contain iron as well). Animal sources include: meat and poultry (organic and grass-fed when possible), fish, eggs and dairy products. Plant-based sources include legumes (beans, lentils, peas, chickpeas), quinoa, tempeh, edamame, nuts and seeds. (1) Many of our vegetables and wholegrains also contain protein, simply in smaller amounts.

How much protein do we need?
How much protein you need per day is very individual. Therefore, it is important to do what works for you personally. How much we need is based on many factors such as activity level, age, gender, the rest of your diet composition and how you digest and utilise protein. Therefore, the amount can fluctuate during different life stages or even week to week.

The recommended dietary allowance for protein suggest that individuals should focus on getting at least 0.8g of protein per kilogram of body weight per day. Again, this may increase depending on the above variables e.g. a dietary intake of 1.0-1.6g of protein per kg of body weight per day is recommended for those participating in minimal to intense activity, respectively.

The different types of protein powder

Whey Protein
Whey protein is isolated from milk and therefore does contain a small amount of lactose. Whey protein contains all 20 amino acids, including the 9 essential amino acids and is digested quickly by the body (ideal for those looking to stimulate muscle growth). (3)

+ Whey Protein Concentrate (WPC): Still contains small amounts of carbohydrates and fats

+ Whey Protein Isolate (WPI): Has undergone another process which further isolates the protein content and is therefore slightly higher in protein. WPI is also generally lower in lactose than WPC with some WPI protein blends reporting to be 99.99% lactose-free. (4)

Plant-based protein powder alternatives (e.g. pea, brown rice or hemp protein)

These are all vegan friendly and will therefore be more suitable for those who do not digest lactose well.

Pea protein is often made from split peas and is generally lower in carbohydrate content when compared to brown rice protein powder. However, some people find that they digest brown rice protein powder more efficiently and with less side effects then when using pea or whey protein powder. Hemp protein powder is relatively new to the market but has the added benefit of containing omega-3 fatty acids. Plant-based protein powders generally contain more fibre. (5) Therefore, choosing a protein powder that works for you personally can involve some trial and error.

It is important to consider that plant-based protein powders don’t always contain all the essential amino acids, this is why pea and brown rice are often pair together in certain protein blends. The amino acid profile also varies greatly from brand to brand, which is why choosing a high quality plant-based protein powder is important. (3) However, if you are consuming other dietary sources of protein such on a regular basis then this is less of a concern.

What to look for when purchasing protein powder?
The ingredient list:
Avoid using products that contain artificial sweeteners, sugar alcohols, preservatives, thickeners, emulsifiers, caffeine and added sugar.

Nutritional Panel:
Protein per serve: 20-30g
Sugar per serve: Less than 5g

How to use it?
You can add protein powder to your overnight oats, bircher muesli, chia puddings, smoothies, homemade bliss balls or protein bars. As mentioned above, whether you need the additional protein from protein powder is very dependent on you personally, you energy needs and so on. Also, depending on your protein needs you can also opt to only include half a serve e.g. if having a bowl of oats with milk and nut butter, you will already be ingesting sources of dietary protein so a full serve of protein may be unnecessary.
