Low-carb diets could shorten life, study suggests

Don't think any of you could have missed this throughout the press today 

A low-carb diet could shorten life expectancy by up to four years, a study suggests.

Low-carb diets, such as Atkins, have become increasingly popular for weight loss and have shown promise for lowering the risk of some illnesses.

But a US study over 25 years indicates that moderate carb consumption - or switching meat for plant-based protein and fats - is healthier.

The study relied on people remembering the amount of carbohydrates they ate.

Quote

"Dr Alison Tedstone, chief nutritionist at Public Health England, said: "This provides further evidence that low-carb diets could be incredibly damaging to our long-term health.

"High-fibre starchy carbohydrates should provide about half of our energy, including fruit and vegetables, while reducing intake of higher fat meat and dairy.""

So there you have if the chief  nutritionist at Public Health England thinks this is evidence of low carb being damaging it must be bad for us then, but as usual most nutritionist's don't even realise what percentage of carbs make up a low carb diet

Dietary carbohydrate intake and mortality: a prospective cohort study and meta-analysis





Collins must have wet her bloomers in excitement when she read the papers 


Here's own fantastical interpretation


Catherine Collins RD FBDA, NHS dietitian, said:

“No aspect of nutrition is so hotly contended on social media than the carb versus fat debate, despite the long term evidence on health benefits firmly supporting the higher carb argument.  Yet supporters of the cult of Low Carb High Fat (LCHF) eating, itself based on a lifestyle choice and the flimsiest of evidence supporting benefit, will no doubt disagree with this newest research on the subject.

for some reason I can't pull a quote, but there's yet another clueless dietician rabbiting on about "eliminating entire food groups" when they are carbs/grains while no doubt championing low fat and vegan diets, as they do.

The most obvious confounder I could see from the study, apart from Willett, is that usually people only turn to low carb diets when they are already ill. I am going to be dead soon and this will undoubtedly be blamed on the low carb/keto diet I have eaten for the last thirteen years and not on the fifty preceding high carb years or the diabeetus.

Epidemiology has become a joke. At least when they had to do it by hand, at least you could admire the hard work. Now days they just put numbers on a computer and manipulate them to dead to get the results mainly the bias of the researchers. By just looking at the arbitrary cut off points you can see it just data massaging.

We, with R.H., can't enjoy the luxury of forsaking a low carb diet!

Bet there are dietitians that would dispute that

Was this what you were wanting to quote ?

In this way, low-carb diets are known to promote weight loss, but the wider, long-term health ramifications warrant further research. In particular, the elimination of whole food groups may be a cause for concern in both the paleo and keto diets i.e. paleo eliminates dairy while both diets eliminate wholegrains. The British Association of Dieticians (BDA) assert that the limitation of whole food groups in a dietary plan is a sign of “fad” diets that should be avoided if healthy weight loss is the goal, rather people should opt for balanced and nutritious diets. This food group elimination can also lead to both the keto and paleo diets traditionally being heavy on animal protein and fat, which clinical studies increasingly suggest may not promote longevity or heart health, they warn.

More hypocrisy from a BDA dietitian then, it's ok for vegans to eliminate whole food groups but not for low carbers. Makes me wonder if there's a financial incentive for the BDA for giving their blessing to vegan diets

Yes the classic "treatment" is to eat carbs every few hours. Doesn't work, obviously.

Collins is spreading her message down under along with a Prof 

Catherine Collins, a dietitian in Britain's National Health Service, said: "No aspect of nutrition is so hotly contended on social media than the carb versus fat debate, despite the long-term evidence on health benefits supporting the higher carb argument.

"Yet supporters of the cult of Low Carb High Fat eating will no doubt disagree with this newest research. Such a stance is at odds with advice from WHO and government health bodies that recommend a carb intake to provide half our daily calorie needs."

Prof Nita Forouhi, from the MRC Epidemiology Unit, University of Cambridge, added: "This finding is spot on in line with the Public Health England dietary guidelines in the UK."

No doubt the study will be included in the evidence based guidelines or would they be that stupid

Oh yes that article by Angela Stanton is good. Zoe Harcombe had a go too

http://www.zoeharcombe.com/2018/08/low-moderate-or-high-carbohydrate/

So did just about everyone else and their dog.

Completely begs the question - if high carb low fat diets are so good, where did all the fat people and diabetics come from and why weren't they there before these diets were invented?

Don't even think of mentioning PURE or the similar Czech study, or Virta, or the literally millions in the "Banting" groups in South Africa and Nigeria, or all the other studies that disagree with the high carb low fat vegan dogma.

Ivor's seen the article in science media centre he calls the site goon central though

Ivor is too polite (ha!) more like fuckwit city.

That meat is a tricky blighter isn't it? We had to eat it for millennia before it suddenly turned round and attacked us.
