What's worse: salt or sugar? That's what I was asked on the radio the other day when being interviewed about the most recent research into diet and health. The research, published in the Lancet, found that too much salt (sodium) is responsible for the disease-related deaths of three million people worldwide each year.
Media reports of this research highlighted the salt thing quite heavily. But in reality, while salt is a big problem we should be paying more attention to, there were 15 other dietary risk factors examined in this research – and we probably need to be keeping an eye on all of them if we really want to have the best health.
This study was big: it aimed to evaluate the consumption of major foods and nutrients across 195 countries, and to quantify the impact of their "suboptimal intake" – in other words getting not enough or too much of them – on death and disability from non-communicable diseases - heart disease, diabetes and colorectal cancer.
What they found was probably surprising to zero health experts. Globally, in 2017, suboptimal diet was responsible for 11 million deaths. Poor diet, they say, is responsible for more deaths than any other risks globally, including smoking.
