Most people over eat because food is tasty. If it didn’t taste good, they wouldn’t over eat. They would still eat to sustain themselves.
Ya think? And food is tasty because it has complex proteins in it. Taste is directly related to the nutritional value in food if you wish to demonstrate that try eating a organic garden tomato and a strip farm store tomato side by side. In clinical tests a garden tomato contains 100 times the lycopathine.
But eat it with food preservatives and you still will not be able to properly digest it. Or I should say your gut bacteria will not be able to. Food preservatives job is to block bacterial digestion, it does not choose what bacteria to block the enzyme action from.
