Plant Protein v Whey Protein: which is better?
Whey protein has been at the top of every bodybuilders diet for as long as time remembers but is whey past its sell by date? And is plant protein a ‘whey’ better option?
Firstly, What is Whey?
Whey can be formed as a byproduct of cheese making or be separated from milk. (As milk is made from whey and also casein).
Whey also contains all the 9 essential amino acids needed, and as I addressed in my previous article, these are the building blocks of life and essential for muscle growth and even athletic performance.
What is Plant Protein?
It is pretty much as it says, it is protein from plants, many plant protein powders use brown rice, hemp, pea and soy as their protein sources.
As it may not contain the 9 essential amino acids required, food sources such buckwheat, quinoa, chia seeds, hemp seeds, soymilk, tofu are great to add into your diet, or simply add some chia seeds and hemp seeds along with some soy milk into your smoothie.
So Which One is More Popular?
Well according to the ‘Plant Based food association’ plant based ‘food sales have grown 43 percent in the past two years, 9x faster than total food sales’
The BPFA also concluded that 79% of Millenials eat plant based, with 79% of Gen Z eating plant based 1-2 times a week, itr also stated that ‘100 percent of Gen Z consumers articulated, environmental concerns, as a motivator.’
So you would factor this into account as to why many supplement brands now offering plant based options alongside their traditional whey, casein options.
Different Types of Whey:


There is more than one type of whey protein, listed below are the different types of whey protein on the market alongside some of their key facts and characteristics.





Whey Option




Characteristics






Whey Concentrate




Contains lactose and is 70-80% protein. Cheaper brands concentrate’s tend to have 30 percent protein and higher end up to 90 percent.






Whey Hydrolysate (Hydrolyzed)




It is pre digested form of whey so absorbs a lot faster, allowing for quicker results






Whey Isolate




Contains less lactose and is about 90% protein, but also contains less nutrients.





Different Types of Plant Protein:
Like its whey alternative, there are numerous plant based protein options available, listed below are some of them along with their key characteristics.





Plant Protein Option




Characteristics






Brown Rice Protein




Brown rice contains the necessary BCAA’s, but does lack lysine so you would need to obtain this from a food source.






Hemp Protein




Contains Omega 3’s, magnesium, fiber, zinc and iron but again lysine is missing so would need to obtain elsewhere.






Pea Protein




Contains all the essential amino acids plus BCAA’s arginine, leucine, isoleucine, and valine.






Soy Protein




Low fat and cholesterol and is a complete protein, so contains all the essential amino acids.






Pumpkin Seed




Low fat and contains magnesium, iron and zinc and has anti-inflammatory and antioxidant qualities.





Benefits and Disadvantages of Whey:
Tabled below are some of the benefits and disadvantages of whey protein:








Disadvantages






Contains all the essential amino acids and BCAA’s so great for muscle building and recovery




Can contain lactose so would affect anyone who is lactose intolerant (which is essentially all of us), and can be difficult to digest






Whey seems to contain more leucine which is crucial in the muscle building process.




High doses of whey can lead to acne






Metabolizes faster




As it derives from milk, typically has higher fat and calorie content






Can be beneficial in weight loss as it reduces the level of the hormone Ghrelin, which stimulates appetite and promotes fat storage.




More sweeteners to disguise the taste






Whey offers 26g (26%) of BCAAs per 100g of protein which is the highest concentration of BCAA’s, of any dietary protein.




Disposal of whey can lead to contamination of sewers and waterways






Can be used to reduce colic in infants









Benefits and Disadvantages of Plant Protein?
Tabled below are some of the benefits and disadvantages of plant based protein:








Disadvantages






Contain high levels of fiber and easier to digest




Not all contain all the essential amino acids but there seems to be contradicting evidence regarding this claim






Contain high levels of antioxidants and nutrients




Metabolizes Slower






Dairy free, so great if you are lactose intolerant




Lower BCAA content






Due to slow metabolization can keep you fuller for longer




Offers 18-19% of BCAA’s per 100g protein (not as high as whey which is 26%)






Cleaner taste and more natural









Great for anyone who has digestive sensitivities









Due to the phytochemicals, (Soy protein) may be effective for cancer prevention









Can be beneficial for blood sugar control









Other than soy it is hypoallergenic so great for anyone with allergies









Better for the planet








Conclusion: Which is Better?

If you are plant based or vegan then this isn’t even a debate as you would be opting for the plant based option, however if you are a meat eater then this could be an open debate.
It may be worth exploring another option to see if that works for you, but bear in mind the environmental impact of your choice.
As if you are looking at sustainability then according to Dr Andrew Berardy, Environmental Nutrition expert at Loma Lida University, stated that “The lower overall environmental impact of plant-based production systems means that the environmental footprint of plant-based proteins is less sensitive to changes over time than that of whey. This means plant-based protein supplements are likely to be the more sustainable choice in the long term.”
