But what about plants?
For the first 25 years of my life, my diet would reach near-carnivorous levels when I was bulking. My diet was made up almost entirely of red meat.
My body grew bigger and stronger, but I also felt like crap: I faced chronic fatigue, constant stomach bloating, and achy joints.
This is a common experience for my clients.
The other issue that weighed on me, is that meat lovers aren’t exactly nature’s best friend. A vegetarian’s carbon footprint is about half that of someone who eats meat, and it’s even lower for a vegan.
In fact, the biggest thing you can do to reduce your carbon footprint isn’t abandoning their cars, but to eat significantly less meat (1). And, new research shows better health outcomes for low-carbon-footprint diets (2).
…so, I did.
Now, I know this isn’t for everyone, but for those who also choose to do this, we need to find other sources of protein.
Do you know where whey comes from?
It’s created by separating components of milk during the cheese-making process.
At one time, it was seen as an annoying byproduct that didn’t have much market value at all. In fact, farmers would literally throw their whey out until food companies finally recognized its high protein content in the 1940s and started marketing it as a food supplement.
Whey was a goldmine: plentiful, inexpensive, high in protein, had a long shelf life, and had tremendous marketability.
Is whey a meat-free protein savor?
Whey is a cheap protein source that can be made to taste great, but there are drawbacks that might make you think twice before you down your next shake.
That leads us to…
That makes whey protein our Superman, who is strong and intelligent but is prone to suffering from sonic and psychic attacks. And on top of that, he’s useless around kryptonite.
Notably, plant-based protein is much easier to digest for most people, which can mean that you actually absorb a greater percentage of the protein you consume. This absorption factor can help overcome a slight price premium you’ll likely pay if you switch from whey to plant-based protein.
Some of you who know a thing or two about protein may ask, “How can plant-based protein be considered a good supplement choice if it isn’t even a complete protein?”
That’s a fair point.
A complete protein is one that has all nine of the essential amino acids, the amino acids that our body can’t produce on its own. Plant-based proteins are sometimes dismissed because they are incomplete, containing some, but not all, of these amino acids.
Fortunately, we don’t need all nine essential amino acids in every single food or meal we eat. If you fulfill the spectrum of amino acids through your total daily diet, then you’re all set.
Also, keep in mind that most plant-based proteins contain 6-8 of the essential amino acids, so they don’t fall too far behind whey or other animal-derived proteins.
If you’re a regular gym-goer and your main goal is muscle growth and recovery, opting for a combination of brown rice and pea protein gets you all the nine amino acids that you can find in whey protein (4).
There are four main options for plant-based protein supplements, each offering different benefits:
A 2013 study found that both brown rice and whey protein have nearly the same benefits for muscle-building and overall health (5). Brown rice protein is super-digestible and is typically very cost-effective.
The only downside of brown rice protein is that it lacks the amino acid lysine. But remember, you can always pair brown rice protein with other plant and animal-based proteins to get your lysine quota.
This fat and cholesterol-free plant-based protein is typically made from yellow split peas. Pea protein contains similar levels of protein per serving as whey and casein (another milk-derived protein supplement).
Pea protein usually contains few ingredients, making it a great choice for clean eating. Just take a look at the ingredients list for most brands — most include only yellow split peas.
The only downside of pea protein is that it lacks one amino acid, cysteine.
This plant-based protein is a derivative of cannabis (it’s actually made from hemp seeds). Don’t get too excited just yet; this protein contains very little THC, the high-inducing ingredient in marijuana.
Another great thing about hemp protein is that it has a high content of omega-3 fatty acids, which are also regularly lacking in typical Western diets. As with the other plant-based proteins on this list, hemp protein digests easily.
A 2009 study found that soy protein has similar muscle growth-stimulating effects to whey protein (6). That’s the good news. The bad news is that the isoflavones found in soy can interact with estrogen and potentially mess with your body’s hormone levels when taken in excess. But, although some evidence has shown soy negatively affects testosterone production, the data are mixed (7).
Like dozens of my clients who have made the switch to a brown rice and pea protein blend, I’ll never go back. Personally, this decision originally came down to valuing the environmental impact and my health, or inconvenience. But once I shifted, I felt my gut health improved and I had no issue maintaining muscle mass. While the research is still limited on plant-based diets for performance, for the general population, it seems to be incurring better health outcomes. Save the world plus be healthier became a no-brainer for me.
It may not sound like a tedious option at first, but don’t dismiss plant-based proteins until you’ve tried it for yourself. You can change the way your body feels and performs, while also helping the environment.
