Poor diet behind one in five deaths

Poor diet is a factor in one in five deaths across the world, a huge study compiling data from every country has found.

A bad diet is the second riskiest lifestyle choice after smoking, and more common, so it topped the list of leading causes of death worldwide.

Other high risk factors are high blood glucose (sugar), which can lead to diabetes, high blood pressure, obesity and high total cholesterol, all of which can be related to eating the wrong foods.

The Global Burden of Disease study found that millions of people are eating bad diets that are low in whole grains, fruit, nuts and seeds and fish oils and high in salt and sugar.

It is the most comprehensive study ever carried out on the subject and collects mortality information to calculate years of life lost and early death risk due to lifestyle and environmental factors.

More than 72% of all 2016 deaths were caused by non-communicable diseases (such as cardiovascular or heart disease, cancer, diabetes, lung disease, and Alzheimer's disease).

The study’s new report also confirmed a significant impact on mortality from air pollution, as more of the world’s population crams into cities.

It also found that people are living longer, with life expectancy in 2016 worldwide at 75 years for women and 70 for men. Japan had the longest life expectancy at 84 and the Central African Republic the lowest at 50. In Ireland it’s 81.

The upshot is that we’re living longer with more disease, and an inevitable result is going to be a growing need for long term medical care. For example, the prevalence of Alzheimer’s is expected to explode across the world as people continue to live longer.

Judging by recent reports about worsening waiting times and management problems in Ireland’s ailing health service, this doesn’t bode well for people approaching later middle age.

One health factor that has been consistently linked to diet and lifestyle choices such as smoking and diet is oral health.

It’s never too late to establish a regular check up and hygiene appointment and get on top of this aspect of your health, and the earlier you do the less pain and expense you can expect to face in later years, when you may have other things to worry about.
