I had to check, and I cant understand why it says high in protein, when only 2,6g per 100g.
The problem is to get enough protein every day, and after you have met your protein, it really doesnt matter how balanced your other kalories is, but a good rule of thumb for anyone is 25% protein, 45% carb and 30% fat, and from there as long your protein is met, you can actually do whatever you want, as long you stay inside your total amount of kalories. If working out regulary, I would had higher protein intake.
What else you need to consider is how nutrient your diet is, and add vitamins and minerals if necessery, and balance with enough fibers, as well.
