Isekai Healthy Kitchen

Stress, obesity, baldness… Tackle any parallel world people’s health problems with a delish!
A nutritionist, Asayama Touya suddenly got sent to another world together with his little sister one day.
After that, he ended up in a restaurant called "Healthy Kitchen", and found out that "all healthy food" tastes bad in that world...

"A tasty, yet healthy food is just a pure fantasy."
That's what most people in Miliasky thought in the country where a Nutritionist, Asayama Touya found himself to be transported into.
Even though he was lucky enough to be sent into a world with good public order, and didn't have any trouble procuring any ingredients nor cooking tools. Since science research didn't really advance well there, the concept of "Nutritional Balance" wasn't really well received there, which in turn made them think that it's normal to eat whatever they like.
But then, he stumbled across a restaurant called "Healthy Kitchen", the only place that seems to serve "food that's supposed to make you healthier," in a world with such a loose view of nutritional balance.
However, what was actually served to Touya, who anticipated some awe-inspiring another world food, was something that is far from what he expected...
With his Nutritionist Knowledge as his weapon, will this ex-office worker be able to turn around the entire norm in the other world!?
