Summary of “We don’t need nearly as much protein as we consume”

His early experiments are some of the few recorded cases of high protein intake having extreme adverse effects – but despite soaring sales of protein supplements, many of us are still unsure how much protein we need, how best to consume it, and if too much, or too little, is dangerous.
Taking centre stage in our health kick is protein, with protein balls, bars and enhanced protein versions of staple products, from cereals to soup, dominating supermarket shelves.
With the global protein supplements market valued at $12.4bn in 2016, it’s clear we’re buying into the idea that we need as much protein as possible.
Protein bars are really just candy bars with a bit of extra protein.
“There’s no need for anyone to have supplements. They’re a convenient way to get protein, but there’s nothing in supplements you can’t get in food. Protein bars are really just candy bars with a bit of extra protein.”
While protein itself isn’t harmful, many protein supplements are high in carbohydrates called FODMAPs that trigger digestive symptoms like bloating, gas and stomach pain.
The risk of consuming too much protein is small, but the bigger risk might just be falling for overpriced products offering us more protein than we need.
“Some products labelled as high protein aren’t, and they’re quite expensive. Anyway, consuming more protein than need is wasteful in terms of money, and it’s paid down the toilet,” says Johnstone.
