Nutritionist Explains: Are pea-based products a good protein source? | Facts, Benefits & More

What is pea protein?

Pea protein is usually made from split peas (yellow peas) and one of the highest quality plant proteins available. Pea protein is considered high quality due to the fact it contains all of the essential amino acids. Furthermore, it has a well-balanced nutritional profile, being low in fat and high in fibre. Pea protein isolate means that the protein content is higher compared to the average protein blend and often lower in calories as well.

How much protein do I need?

It is recommended that the average person requires 0.8-1.2kg protein per kg of body weight. However, protein needs increase in those that participate in strength or endurance sports, with a range of 1.2-2g of protein per kg of body weight. Furthermore, it is recommended to have an extra 15-25g protein within 24 hours of a to maximise muscle repair.

How much protein Is in pea protein? Is It Enough?

Benefits of pea protein

1. Protein helps with muscle repair: whilst this is not specific to pea protein isolate, it is important to understand the main reason for supplementing with protein powders. When we exercise, whether cardiovascular or strength training is preferred, the muscles become damaged. Supplementation with protein can help repair this muscle damage, as it helps to promote protein synthesis – this is integral for new muscle growth.

2. Pea protein contains all the essential amino acids – amino acids cannot be synthesised by the body and can only be obtained through dietary sources. Plant-based sources of protein have long been thought to be incomplete proteins however, research now suggests that pea protein is a complete protein. This means it contains all the essential amino acids, so a blend of different protein sources is not necessarily required.

3. Pea protein has a high bioavailability – the higher the bioavailability, the higher the percentage of protein that can be absorbed and utilised in the body. Pea protein has a pretty similar bioavailability to both casein and soy protein powders. This suggests efficacy of pea protein as a supplement is likely to be high and may be helpful in helping you meet your protein needs.

4. Pea protein may help increase satiety – protein has been frequently studied for its hunger busting properties. Evidence suggests that the high protein content found in in pea protein can help to reduce hunger and help you feel satisfied for longer. Whilst this is useful for post-workout muscle repair, increased satiety associated with pea protein supplementation may help with weight loss.

5. Pea protein may help to reduce blood pressure – peas in their food form as well as protein powder form may have a positive impact on blood pressure by aiding vasodilation. Vasodilation reduces resistance in blood vessels, meaning the heart doesn’t have to work as hard to pump blood around the body. Lower resistance often means a lower blood pressure and improved cardiovascular health.

What is the nutritional make-up of pea protein powder?

Myvegan pea protein is predominantly made up of the protein itself (88%), with small

amounts of carbohydrates, fat and salt. It is also refined sugar-free, so won’t cause the energy crash associated with foods high in sugars. This makes pea protein a suitable mid-morning or mid-afternoon snack for those wanting to include protein in more of their meals.

Does pea protein have any side effects?

Due to the higher fibre content of pea protein, it can sometimes cause some GI upset. If this happens to you, try reducing the portion size or frequency of use. Alternatively, you could try a pre-made protein blend, or mix with another protein such as brown rice protein.
