I have reviewed the top rated healthy food stores or delivery services. There are some issues:
First, they are still too expensive. It costs C$ 20 per meal for a family of 4. So a full daily meal can cost above C$ 50 including snacks. It's almost twice the money of what you can make by yourself with the best quality recipes. The only good thing is that you save the cooking time. So, many people just can't afford to enjoy healthy food. Therefore, it's not the best solution to solve current health issues in the society.
Second, they use terms like plant based food, calorie friendly food to replace healthy food. Those are totally different concepts. Also, there is keto or similar restricted food, which is already proved to be not so healthy. In many cases, unhealthy food can make larger part of the menu as well.
Finally, because the high costs of operation, such as rental, marketing, salaries for the chef, and other unavoidable costs, it may not be able to reduce the price significantly.
I think the best solution could be:
The recipes must be really good and inexpensive. The cost of ingredients will be lower as well. But if you want to add meat, such as chicken breast, salmons, the savings could be limited.
Only include well designed raw materials. But the cooking time should be as less as possible. It can save the costs for store front and chefs. The best case is that people can just take it out, make some simple preparations, put into the macrowave, after several minutes, they can eat a quick but delicious meal.
I think, breakfast and snacks could be totally different from lunch and dinner in the process.
