Hello !
I didn’t receive any scoop with my Jimmy Joy and would like to know how to easily mesure the quantity of food I need. I understood it must be 173g, but is it possible to know the equivalent in ml on the shaker ?
Second question, have there been any health long-term studies on meal powders ?
Thank you,
Stéphane
Yo Stephane!
Measuring with the ml only gives a rough estimate, if you fill the Jimmy Joy shaker till 350 ml, you are somewhere around 175 grams.
As for your second question, there are no officiel studies been carried out on this type of meals, but a lot of DIY experiments have been done, see the following links:
Thank you very much Karel for these answers !!!
I would love to find more medical studies but it must be too early probably.
Have a nice day and thanks again.
Stéphane
I’m on the same page on that one, medical research on powder meals would be very intereseting!
No problem at all, I’m glad to be of service! You too have a nice day 
Hi Karel,
For information, I talked about powder meals with a gastroenterology specialist yesterday. I showed him the ingredients also. He don’t advises these meals because we don’t have enough feedbacks about the synthetics vitamins in the long term and it could be suspected to create some cancer.
It was also my main concern about Jimmy Joy when I read all these chemical ingredients on the packaging. I think I will be more vigilent next time and will try some alternatives like Bertrand Bio (in France).
Take care,
Stef
Hello Steff!
I see your concerns, here is a quote from Nutrition department from Harvard Medical School:
“Read enough nutrition news, and you’ll see that not all scientists agree on multivitamins. Some say that there’s not enough proof that multivitamins boost health, so they don’t recommend them. Other scientists point to studies that seem to show a link between multivitamin use and increased risk of death. But those studies are flawed. Looking at all the evidence, the potential health benefits of taking a standard daily multivitamin seem to outweigh the potential risks for most people.”
I hope this quote helped a bit with your worries!
Talking about “chemical” ingredients is a tricky one, from my chemistry background everything is chemicals. It’s the consumers idea of bad chemicals which is just an personal feeling of wrong food. From the nutritional point of view, the body doesn’t distinguishes between chemically made and naturally accuring, if its exactly the same molecule structure it works the same in the body.
I don’t know if this helps in your search 
but this is my point of view on the subject 
Thanks Karel to take the time to answer me and find this quote .
Like in any industries, there is pros and cons, but we are talking about health. Personnaly, I would feel much more secure with natural ingredients in the recipe.
