If only people would go back to a pre world war 2 diet without all the processed foods and junk food from take away outlets. Treats now and then in moderation is just that a treat. But we are so conditioned to eating all sorts of things by high pressure advertising.
Sadly too, many people are time poor and just want to get meal time done quickly, especially with a family and working full time. Then the pressure of getting children to do homework every night. There is way too much pressure on families just to survive since the 1970’s and here we are in current times with that pressure at breaking point, with additional pressure of the cost of living crisis and the housing shortage.
There has to be a better way to live and stop being so depleted of quality time, with affordable quality food and the time needed to prepare healthy meals. Without the affordable healthy foods available to everyone, of course we will become ill, and that includes the brain being impaired.
