Fat vs Carbohydrates - take a look at the evidence

By Jane, Jan 4 2018 10:16AM

These days everyone in my industry likes to claim that their ideas are "evidence-based", and yet so often the evidence that they refer to is either anecdotal or from their own poor quality research, often ignoring years of respected research that states the opposite view.

I don't like to refer to scientific evidence unless it is clear, well presented and comes from a source with no conflict of interest. And in the field of nutrition this is very rare!

Each year, the London-based analytics company Altmetric releases a ranking of the 100 most popular research articles that year, across all scientific diciplines.

Here is their report from last year. Take a look at number 1. Here is the summary:

"1. Associations of fats and carbohydrate intake with cardiovascular disease and mortality in 18 countries from five continents (PURE): a prospective cohort study

Yet another piece from The Lancet with a catchy title, this study compared the diets of 135,000 people from 18 countries. The result? Low-fat diets were associated with a higher likelihood of heart attacks and heart disease.

Meanwhile, low-carb diets appeared to be significantly healthier, just once more affirming the notion that dietary fat is not the enemy, while excess sugar definitely causes harm.

Global dietary guidelines should be reconsidered in light of these findings, the researchers wrote in the paper."

I agree. This is why I support the Public Health Collaboration in our attempts to do just that.
