A few weeks ago, I wrote about the body’s stress response, or “fight-or-flight” response. The article described what happens inside the body in a situation of immediate danger – the alarm phase. The changes I described are mainly due to the stress hormone adrenaline. It triggers a cascade of mechanisms designed to save our life. The effects of adrenaline are very short lived.

For more than 60 years now, we have been told to limit our fat intake or – better still – to avoid it altogether, because not only does fat make you fat, it also causes heart disease.

People did listen: We now eat a lot less fat than we used to, especially of the saturated kind.

The tomato sauce on pizza or the lettuce on a burger, baked beans in the morning and a glass of orange juice … that’s three already of our five-a-day. Surely that’ll do?
Why would it be necessary to learn about nutrition? Grandma never knew and she managed just fine by … simply eating food. But that’s just it: Grandma just ate food, because that was all there was. She couldn’t have gone far wrong. Today, however, we are surrounded by “Frankenfoods” – products that are manufactured to look and feel like food, even taste good, but are entirely artificial and provide very few, if any, of the chemicals we need to thrive, but plenty of chemicals that are unwelcome, even toxic, and that our body then has to dispose of.
