People tend to enjoy food because of the taste rather than nutrition. I wonder whether it is possible for food to be nutritional, tasty and affordable? To most people, nutrition is a term that is intangible. But taste is different, when something is tasty, it is enjoyable. Cost is also something very tangible as it typically implies gives or takes; for example, you pay more for food then you might have to spend less on clothing or entertainment.
The challenge here is how to create highly nutritional low cost food that can be cooked in such a way that is tasty and can become the staple diet of the mass. One example is the soya milk that has helped many poor people from the Asian countries nutritionally more than half a century ago.
The picture shows a popular brand of soya milk drink.
A lot of nutritional recipes claim the resulting dishes are tasty; may be to the person who created the particular recipe, but many times they are just good enough but not to the point that people would crave for them.
Unfortunately, the way I see it, nutrition would not play an important role in the culinary industry unless there is government intervention with regulations, such as mandatory nutrition facts provided in all food packaging, including the paper that wraps the burger from a fast food restaurant and on the menu of a regular restaurant.
Without government intervention, we have to do our own fact finding on nutrition. An example of a credible nutrition website is the WHO (World Health Organization), a specialized agency of the United Nation, where you can find many good scientific reports on nutrition, https://www.who.int/nutrition/topics/en/. Avoid going to websites that are not credible, such as this one from the Livestrong foundation, https://www.livestrong.com/scat/diet-and-nutrition/. This particular website showcases many celebrities, in particular their own stories on diet and nutrition. Unfortunately the information is not scientifically based and it is more a platform for advertisements from the food industry.
