Recent BMJ research suggests that a low carbohydrate-high protein diet (like the Atkins diet) is associated with an increase in risk of cardiovascular disease. The editorialists for this paper add: "Although these results are based on an observational study, their biological plausibility seems self evident. A low carbohydrate diet implies low consumption of wholegrain foods, fruits, and starchy vegetables and consequently reduced intake of fibre, vitamins, and minerals. A high protein diet may indicate higher intake of red and processed meat and thus higher intake of iron, cholesterol, and saturated fat. These single factors have previously been linked to a higher risk of major chronic diseases, including cardiovascular disease, in observational studies,9 so it is not surprising that this combination of risk factors is linked to a higher incidence of disease and mortality. This problem becomes even more challenging considering that these types of diets are mainly targeted at overweight and obese people, whose diets tend to be of lower quality." Do you know patients who have gone on Atkins to lose weight? |

There were also previous studies that hinted toward a possible increased risk of cancer in those consuming high protein diet. These associations are not that straightforward simple. Nutritional studies can be tricky and potential biases should be considered. However. it seems that diets with excess of certain nutrients are not healthy. So, a balanced diet containing protein, carbohydrates, fat, fibers and vegetable and fruit is important. Too much protein, especially derived from processed meat can be harmful not merely due to the protein excess, but the various prooxidants that are consumed.

Getting a person to lose weight is the first step and this is best achieved by low CHO diets. When they reach a lean BMI they can then have more CHO in a maintenance diet so these studies don't tell the whole picture. Averting type 2 diabetes is step 1. If they end up diabetic they will find the only way to lose weight is the ELF diet which most find they can't do (eat less food). Do carnivores have more CVS disease? If not why not. How do lions and killer whales get all their water soluble vitamins? The only fat carnivore is a domestic dog. There are no fat jaguars except in zoos.

Why aren't there more carnivores in coronary care units? Do Esquimaux have more coronary artery disease on a traditional meat-based diet? There are no Greek salads in the Arctic Circle.

Difficult to find papers on Inuit CVS health, excpet in the face of the Western obesity epidemic. This paper looked at records recently re-discoverd from 'pre-Western' Greenland Inuit in the 1960s. They found LVH under 30s, not related to high blood pressure which only developed above 40 years, and attributed this to a life of "marked physical activity". This paper might be of interest, but no olnine copy is available: Arch Pathol. 1970 Nov;90(5):433-8. Cause of death in 339 Alaskan natives as determined by autopsy.Arthaud JB.
and this paper is much more modern and reviews the cardiovascular helath of Nunavik Inuit, whih is not good. They conclude that "The current belief that the Inuit are protected from Cardiovascular disease is seriously questioned by the results of the present study."http://www.ncbi.nlm.nih.gov/pubmed/20548980 THis study demonstrated "the major health problems facing the Greenlandic community are the high mortality from suicides and homicides, the prevalence of violence often triggered by alcohol, the many accidents, the high infant and child mortality and the high mortality from preventable cancers (lung and cervix)."

According to what I read in the newspaper in my country the study would have been going on for 16 years. How is that possible? Did people start to follow the Atkins/LCHF diets already 16 years ago? |

In Response to Re: Low carbohydrate-high protein diet increases risk of cardiovascular disease: How about this for a radical thought: Low carb, high veg Posted by James Carroll High vege is ok if the vegetables are not root vege. Eat the green tops and the green ones not the ones under the soil. That way we keep above the soil longer and I tell patients that; descend forever to the Underworld of the potato, turnip, carrot, sweet potato etc.
