Thank you all for your opinions and links to the relevant research. Below I've laid out my interpretation of the research and share some more information about the planned content of Queal Athletic 5.0.
Protein in Queal 5.0 Standard:
- 21g per 100g
- 35,2g per 700kcal
- 105,5g per 2100kcal
Protein need - Average Adam
At Queal we take in various sources when considering our formula. These range from input from our customers to recommendations from production. One other main source is the EFSA recommendations. Especially for vitamins, they make very well reasoned and accurate recommendations. They also make recommendations for protein intake.
The EFSA recommendation is 0.83kg per kg of body weight per day.
(In the US the recommendation is 0.8kg)
This is the recommendation for adults. (see here for the summary and here for full article)
For an individual who weighs 80kg (average in Europe, males 18+) this means you would need 66.4g of protein per day.
Queal Standard 5.0 will provide you with 158% of that.
And before we move on, this is in essence what Queal Standard is made for. To provide you with all the essentials for the day. But at the same time, we also believe that protein is a very good source of energy. And quite some research points to arguments for an increased recommended intake per day.
Examine.com is a great aggregator of excellent research and they recommend that you (Average Adam) should eat 1.2g to 1.8kg of protein per kg of body weight per day. In the cited study they found that eating this amount of protein led to an increase in muscle mass. Two things should be noted however. The first is that all participants ate 40% more calories than they needed to sustain their weight. And that the group in the low protein situation didn't lose a significant amount of muscle mass (note: not significant means that the fluctuation is nothing more than random variation, so for all intents and purposes they stayed at the same amount of muscle mass (and I find it a bit sloppy from them to write it up like this, but on the other side it could reference to a bigger trend)).
With this information in mind. An individual of 80kg should need between 96g and 144g of protein per day.
With Queal you are within this range, but yes it's on the low side.
A final note for Average Adam. An individual who weighs 80kg and is moderately active is probably consuming more than 2100kcal (3 meals of Queal Standard) per day. This can be in the form of calories from drinks, snacks, etc. Depending on the caloric calculator used you would need about 2450kcal to sustain your weight. If you would eat all of this from Queal, you would consume 123g of protein per day (right in the middle of the recommendations from Examine.com)
Protein need - Sports Sam
Protein in Queal 5.0 Athletic:
- 26,8g per 100g
- 49,5g per 766kcal
- 148,5g per 2300kcal
If you're very active you may very well like to increase your protein intake to much higher levels. Also because there aren't many (if any) negative consequences from consuming more protein, you may even want to eat more than needed.
Examine.com recommends between 1.4 and 2.2g per kg per day for very active adults.
They recommend 1.8 to 2.6g per kg per day for muscle gain.
And even 3.3kg to possibly minimise fat gain.
In the article cited by @Skymirrh on strongerbyscience.com they found that the average intake of top athletes was 1.5g per kg per day (which is a bit lower than the recommendation above). The article also gives a recommended minimum for athletes of 120g per day, which Queal Athletic provides (at 2300kcal per day, which is probably less calories than you will consume).
I'm assuming that Sports Sam also weighs 80kg, but is much more active than Average Adam.
This means that the total need for calories per day would be 3100.
If all of that is consumed from Queal Athletic 5.0 (again, most use Queal only for 1 or 2 meals, but this is just to show what it would also mean on average), you would have exactly 200g of protein, or 2.5g of protein per kg per day.
I know that I've taken the favourable case for Queal here, and I invite you to see what the recipe would mean for you. But I hope also that I've been able to show that the protein content is still very high and that Standard maybe is a bit more standard/average, but for everyone that is using Athletic that you can still trust on Queal to provide you with the protein you need.
As a last note on protein. Many sources advise you to take a small protein shake about 30 minutes after your workout and I agree that this could be good advice. This (mini) meal was never intended to be replaced by Queal and I think this could add to your total protein intake for the day (on training days).
Although I know it's hard to change someone's mind, especially online in a forum, I hope the above gives you some insight into the considerations of the total protein content. For anyone reading this discussion, I also encourage you to read more about the fats in Queal and the carbs (and lower GI). And for all who want to try Queal 5.0 Standard, you can already get it with our limited edition Royal Rice Pudding.
