The scary truth about protein supplements

The scary truth about protein supplements

3 Things that shouldn’t be in your protein supplement

Do you or anyone you love take a protein supplement?

Matt Frazier is the marathon runner and ultra-endurance competitor who founded “No Meat Athlete.” He wanted to find a healthy protein powder to complement his athletic kids’ wholesome plant-based diet. So he started researching the available options, and he was horrified by what he learned.

A protein supplement isn’t for everybody. But if you’re someone who might benefit from it, then you deserve to know the facts so you aren’t spending an arm and a leg (Newsflash: Most protein supplements aren’t exactly cheap!) to buy a product that might wind up doing more harm than good.

The following from the Food Revolution Network provides the good and bad.

Over the years, we’ve talked a lot about protein: How much you needhow to get it from
food
, and whether or not
you should supplement
.

And there’s no one-size-fits-all answer to that last
question…

Although I’ve managed to get plenty of protein from whole
foods for the past few years, I’ve always acknowledged that for certain people
— people who want to add muscle, try to hit macronutrient levels, or just want
some peace of mind — supplementing makes more sense. 

But if you take protein powder yourself, there’s one question
you should most definitely know the answer to: 

What’s in your protein powder?

I started looking more closely at protein powders a few
months ago, for my kids’ sake. They’re both young plant-based athletes, and —
call it parental paranoia if you want — I find myself worrying about their
picky eating habits, specifically that most of the foods they love (fresh
fruits and vegetables, especially in smoothies) aren’t necessarily dense in
protein or, more generally, in total calories.

But when I started looking at the ingredient lists of the
common plant-based powders, I was surprised and disappointed. Unfamiliar and
artificial ingredients, plus sweeteners (even natural ones) that I knew they
wouldn’t like the taste of in their smoothies.

So I did some more digging… 

And it got worse. Waaay worse. 

Today I want to share a bit about what I found, in hopes that
it helps you to make more informed decisions when choosing a protein powder, if
you choose to use them. 

And I’ll start with the one that scares me the most… 

1. Heavy Metals and Other Carcinogens

Now, I know what you’re thinking.

Heavy metals and chemicals in my protein powder? Nah. No way.
I get the good stuff. And it comes from plants. 

Think again. Last year, the Clean Label Project™ completed
study
examining 134 plant-based and animal-based protein powder products
 from
52 different brands. They screened for over 130 toxins, including heavy metals,
BPA, pesticides, and other contaminants with ties to health
problems.  

And you know what they found? (You might want to sit down for
this one.)

Many of the most popular plant-based powders were ranked the
worst for their high levels of contaminants like heavy metals. In fact,
plant-based proteins ranked lower than animal-based proteins on average. 

So how does that nasty stuff get into your powder? 

According to Clean Label Project, “Contaminants are the
result of sourcing and production practices. Contaminants can be found in soils
because of pesticides and mining run-off (ex. heavy metals) and can be absorbed
into plants just like nutrients. They can also be the result of the
manufacturing process (ex. BPA/BPS is using the lining of cans and containers
and leach into the protein powder.)”

Let’s take a closer look at some of the most common heavy
metals and chemicals to see what the study actually found: 

BPA (bisphenol A)

By now you’ve probably heard of BPA, but most people don’t
actually know what it is. BPA, or bisphenol A, is a chemical used in a lot of
commercial product packaging as a way to strengthen the plastic. 

High amounts of BPA, however, are known to cause cancerous
tumors, birth defects, and other mental and physical health issues

A few years ago, BPA garnered a lot of attention when it was
discovered to leach
from plastic into drinks
, like water. Since then, many popular water
bottles have gone BPA-free, but it’s still commonly used in many food
containers, including some plastic containers that store protein powder, or
even the plastic measuring scoop often included in the tub. 

The Clean Label Project study found that 55% of protein
powders tested had high levels of BPA, and one had over 25 times the allowed
regulatory limit in just one serving. 

Lead

According to the study, nearly 70% of plant-based protein
powders contained measurable amounts of lead. The potential mental and physical
health problems associated with lead are well documented,
so why is it showing up in these protein powders?

The primary problem seems to be where the ingredients are
sourced from. Lead in the ground seeps into the growing food before harvesting
and stays there as it’s turned into your powder. 

Arsenic

Arsenic is a naturally occurring chemical often found
in water, food, and soil.
 

This is a particular problem with rice-based products,
which is grown in water-flooded conditions, and arsenic
in the soil
 finds its way into the roots of rice crops and is eventually
stored in the grains.

Arsenic, of course, is also known to cause a number of health
problems including cancer

So why is it in plant-based protein powder? Primarily because
of poorly sourced rice protein isolate. 

Cadmium

According to the same Clean Label Project study, 74% of
protein powders contained measurable amounts of cadmium.  

Cadmium is another natural toxic element often found in rocks
and soil, and because it does not corrode easily, it’s often used in batteries.
That’s right, batteries. 

And you guessed it, cadmium also has links to cancer

But what if my powder is organic? 

That was one of my first questions as well. But organic,
although good for other reasons, is no help when it comes to heavy metals.
Organic protein powders had on average twice the amount of heavy metals as
non-organic options, so if a brand doesn’t disclose heavy metal information to
you, you’re left wondering. 

2. Sweeteners and Flavorings

These days, sweeteners are added to just about every
processed food, so it should come as no surprise that they’re also often added
to protein powders. 

But here’s the thing. 

Sweeteners are totally unnecessary. Same goes with flavors
(natural or not) like vanilla. The only reason companies often adds the
sweeteners and flavors is to try and mask the taste. 

In turn, however, they’re adding unnatural ingredients that
not only taste fake, but are potentially harmful. 

Take a look at common artificial sweeteners like acesulfame
potassium, sucralose, or splenda, for example. These sweeteners with their
potent taste not only train the brain to crave sweet foods, but are known
to increase the
risk of cardiovascular disease and obesity. 

How about natural sweeteners like stevia or monk fruit, you
ask? 

In my opinion, if it isn’t serving me (or my kids), I don’t
want to add it to my smoothie, where the additional sweetness only makes things
taste less natural. I want my smoothie to taste like the fruit that’s in it,
and no sweeter.  

3. Fillers, Preservatives, and Gums

While the contaminants scare me most, the biggest shocker I
came across in my research on protein powders was what I learned about
fillers. 

First, there’s a reason you don’t see percentages next to
protein powder ingredients on labels.

Many brands, like the one I used to take, boast a “blend of
pea, rice, hemp, and chia” (for example) to create the appearance of a complete
amino acid profile. But if they’re not telling you the amounts of each in the
product, then nothing prevents them from using 95 or even 99 percent of the
cheapest powder, and only blending the others to make up the remaining 5
percent or less. 

There’s nothing to tell you it’s pretty much just one type of
protein. And that the amino acid profile is incomplete.

In an industry so unregulated as supplements are, it’s not
hard to imagine that’s what they do.

Besides cheap proteins, dextrin (a carbohydrate from starch)
and maltodextrin (produced from corn, rice, potato starch, or wheat) are common
fillers added to protein powder to bulk it up. 

Then there are gums, like xanthan gum, which is derived from
corn and soy and often used as a thickener in protein power. These gums are
totally unnecessary and some people can find them hard to
tolerate
.

Lax labeling requirements mean you can’t really feel
confident about what’s in your powder. Sure, you might have an ordered
ingredient list, but when you don’t know how much of each ingredient is
included, you have no idea if your powder is really what it claims to be. 

Where This Leaves Us

When it comes to protein, the
best place to get it is from food. And for many people, that’s not hard to
accomplish. If you eat a wholesome diet based around real food, then in the
vast majority of cases that will leave with more than enough. (And keep in
mind, the average American gets about twice as much protein as they need – and
in the industrialized world, excess protein consumption is causing vastly more
disease than inadequate protein.)

But if you’re over 65 or highly active, and vegetarian or
vegan, then you may want to consider supplementing – especially if you don’t
include soy, gluten, or abundant legumes in your diet. 

If you choose to use a protein supplement, the best bet is to
look for one that is fully compliant with California’s super stringent Prop 65
requirements. That means, any heavy metals and other carcinogens present are
less than 0.1% of the “No Observable Effects Level” set by California. And
remember, you are looking for brands that explicitly state that they comply
with California’s proposition 65 – not just in California, but everywhere else,
too!

And make sure to read the label to insure that the protein
you’re getting is organic and is free of any undesirable sweeteners,
flavorings, chemicals, preservatives, fillers and gums that you don’t want.
Bonus points if it uses a range of protein sources, tells you how much of each
is included, and has a diverse amino acid profile.

A protein supplement isn’t for everybody. In fact, it isn’t
even for most people. But if you’re someone who might benefit from it, then the
way I see it, you deserve to know the facts so you aren’t spending an arm and a
leg (newsflash: most protein supplements aren’t exactly cheap!) to buy a product
that might wind up doing more harm than good.
