^^ there is truth to this.
Of course, I like doritos, and I know how bad they are for me...
and its HARD to make a nutritionally good bread. My wife makes sourdough. We've had the same starter for two decades plus now, its fair to say she's had some practice. Makes great white bread (or cuban bread or french bread or italian bread), tolerable english muffins, very good pretzels. We use a good high protein flour (King Arthur brand bread flour) - but to try and make a whole wheat flour or a seeded whole wheat flour and really juice the protein numbers???
The results are much less palatable. In an emergency, its easier to spread low sodium peanut butter on the finished white bread and accept the chemical residues present in exchange for the much higher protein (and salt, and fat) than to try and make a nutritionally great bread to start with.
