Polyunsaturated Fats Give Sugar A Bad Name.
A friend pointed out an article in this mornings local paper, referencing a recent Melbourne University study, published in the Nature journal, Nutrition and Diabetes, discussing the impact of so called ‘Paleo’ Low Carb High Fat Diets (LCHFD) on the symptoms of metabolic disorders, including obesity and diabetes.
“…recent studies have suggested that there could be some potential benefits for reducing carbohydrate intake in favor of increased fat. It has also been suggested that low-carbohydrate diets be recommended for people with type 2 diabetes.
In our study, we were specifically interested in determining whether an LCHFD would improve β-cell function and therefore whether it may be useful for preventing deterioration in glucose control in a model of obesity and type 2 diabetes.
…we examined the effect of an LCHFD on glucose-stimulated insulin secretion, which is also crucial for maintaining normal blood glucose control.
…our study and others clearly show that increased dietary fat…is…associated with greater weight gain and insulin resistance
…rather than being beneficial, an LCHFD may ultimately contribute to faster decline in β-cell function.
Overall, this diet resulted in greater impairment in glucose tolerance. Our results do not support the recommendation of an LCHFD for use in prediabetes;”
Although the authors have failed to acknowledge the significance of the relatively high unsaturated fat content (which I have discussed in previous posts on the topic) of the diet in question here, this very recent study provides further evidence in relation to the dangers of sugar restriction, and increased fat consumption, particularly in relation to disorders of metabolism including obesity as well as diabetes.
Once again it seems as though a diet restricting fat intake (particularly polyunsaturated fat) and providing sufficient protein from milk cheese and gelatin and increased amounts of sugar from sweet ripe juicy fruits, fruit juice, honey and sucrose, is a rational and logical approach to improving metabolic function, providing protection from related issues of diabetes and obesity.
