Mouse evidence suggests that high fat diets cause inflammation in the brain and results in damage to the nervous system. Can these results be translated to humans?
It’s commonly accepted that higher protein intakes reduce cravings for sugar. But is that idea supported by the evidence?

Candida overgrowth can affect many people, resulting in mild to severe symptoms. In this review, Cliff summarises the evidence-based natural treatments available.
Recent media articles have highlighted the debate between low-carb and low-fat diets for treating diabetes. In this article, Cliff examines recent media reporting and the evidence for diet and the treatment of diabetes.
The idea that total and saturated fat intake is a risk factor for heart disease still persists. In this review, Cliff examines a recent meta-analysis that casts further doubt on this.
Some animal studies have suggested that a keto diet can result in insulin resistance and this is supported by some glucose tolerance challenges in humans. But is this phenomenon all that it seems, or could this actually be a healthy adaptation to a low-carb diet?
There is an endless debate between proponents of high-carb vs low-carb diets. So, how can you decide which is best for you? In this article, Cliff Harvey PhD summarises the research to show how you can determine what’s best for your body.

There is concern about the insulin stimulating effects of dairy. In this study, the effect on insulin and blood glucose homeostasis of increased dairy intake was explored.
A1 protein from milk has been suggested as a risk factor for health, while A2 is promoted as a health food that avoids these risks. Find out what the research tells us about A1 vs A2.
Low-fat dairy is recommended in dietary guidelines over natural, full-fat diary, but is this recommendation actually justified by evidence? Or is it simply outdated?

ABC News https://www.abc.net.au/news/health/2019-07-04/who-saturated-fat-recommendations-out-of-date-expert-team-says/11274136 Article Summary In a new study published in the British Medical Journal,1 18 well-known researchers have disputed the World Health Organisations dietary guideline to reduce saturated fat to less than 10% of daily calories, and have stated that this dietary guideline is not backed by evidence. The authors summarised the key points of the paper as: 2018 WHO draft guidelines on dietary saturated fatty acids and trans-fatty acids recommend reducing the total intake of saturated fat and replacing it with polyunsaturated and monounsaturated fatty acidsThe recommendations fail to take into account considerable evidence that the health effects of saturated fat vary depending on the specific fatty acid and on the specific food sourceMaintaining general advice to reduce total saturated fatty acids will work against the intentions of the guidelines and weaken their effect on chronic disease incidence and mortalityA food-based translation of the recommendations for saturated fat intake would avoid unnecessary reduction or exclusion of foods that are key sources of important nutrients Comment The evidence ‘against’ saturated fat has been lacking for the entirety of the advisement against it. Of the systematic reviews and meta-analyses published, only the Hooper analysis showed detrimental effects from increasing saturated fats at the expense of other fats and even this finding has been disputed as the statistics used gave greater weight to smaller, more biased studies (as covered in a previous CARR). It is completely baffling that a dietary guideline based on such weak evidence (at best) continues to be…
