It never ceases to amaze how myth can survive across generations. Take the bible for instance! 😀
The fruit thing is a prime example of both myth, and peoples need to have neat little bite sized answers that don’t require too much thinking.
It’s not so much the combining of ‘fruits’ and other foods that’s an issue, but more a question of what you happen to be eating as a whole. All fruits are not equal for one, with varying degrees of sugar and fiber in each, so the most important factor becomes insulin impact, which of course most people when you tell this to either look puzzled, or roll their eyes. Another factor is timing. Throw back a water melon before running a marathon and you’re going to hit a brick wall pretty quickly as the insulin spike rips all available glucose from the blood, but eat one afterward and you just aided glycogen uptake (energy), sped recovery, and replenished ATP stores (muscular contraction). And so it goes on… I’m aware I tend to get a little technical when I post anything related to nutrition & exercise, but then I’m not in the habit of being glib either, and it’s the attention to detail that people tend to forget, or just don’t invest the time in.
Anyone who takes the time to learn and understand the simplicity of insulin response to foods will forever understand the impact of everything they eat. I wish it was taught in schools, but then of course it won’t be as long as the major food corps continue to seek gargantuan profits from cheap to produce crops, including the number one drug on the planet, sugar.
