The study evaluated the effects of fat and fiber consumption on sex hormones in men.

Men were assigned into 2 groups eating (a) Low fat, high fibre diet (b) High fat, low fibre diet.

The men on the high fat, low fibre diet had higher total and sex-hormone-binding-globulin (SHBG)-bound testosterone levels by 13% and 15% respectively.

Higher testosterone and SHBG levels are associated with a reduced risk of metabolic syndrome.

The case for high fat/low carbohydrate diets in diabetes management

This paper reviewed the evidence of low fat/high carbohydrate diets and high fat/low carbohydrate diets in the management of diabetes.

The review found:
(a) Low fat/high carbohydrate diets raise blood glucose levels which increases the risk of heart disease, high blood pressure, obesity and diabetes.
(b) The current epidemic of obesity and diabetes over the last 30 years has coincided with a significant decline in fat consumption and an increase in carbohydrate consumption.
(c) Evidence from trials has shown that the high fat/low carbohydrate diet is more effective than the low fat/high carbohydrate diet in the treatment of diabetes.
E.g. High fat/ low carbohydrate diets:
(i) Result in more weight reduction.
(ii) Have a greater improvement in various cholesterol values.
(iii) Control blood pressure.
(iv) Reduce triglycerides.
(v) Increase high density lipoprotein (HDL) cholesterol levels.#
(d) Scientific evidence has shown the traditional low fat/high carbohydrate diet treatment for diabetes has an ambiguous record at best.
(e) The objections to a high fat/low carbohydrate diet have very little scientific basis.

The findings of the paper are that some form of high fat/low carbohydrate diet is a viable option for patients with diabetes.

Recipe of the day

Salmon and Garlic Spinach

Ingredients:

Food Mall: Salmon Fillets

◦3T + 2T fat

◦2 salmon fillets
◦S&P
◦1/2 lb. fresh spinach
◦3-5 gloves garlic, finely chopped

Method:
In a saute pan over medium high heat, melt about 3 T fat. Pat the salmon dry with a paper towel and sprinkle with S&P. Place the wing in the pan and saute for about 7 minutes, flip once you see a little bit of color and saute on the other side. You shouldn’t see any pink or redness, if you do, cook it longer.

For the spinach, use the same saute pan and saute the garlic in about 2 T melted fat. Add the spinach all at once and let it sit for about 2-3 minutes. Then use some tongs or a spatula to turn it over so the fresh spinach gets wilted. This should take less than 10 minutes.

Low fat diets implicated in the rising epidemics of obesity, lipid abnormalities, type II diabetes, and metabolic syndromes

Published in the J Am Coll Cardiol, 2004; 43:731-733

The diet–heart hypothesis: a critique
Sylvan Lee Weinberg, MD, MACC*,*
* Dayton Heart Hospital, Dayton, Ohio, USA

The low-fat "diet–heart hypothesis" has been controversial for nearly 100 years. The low-fat–high-carbohydrate diet, promulgated vigorously by the National Cholesterol Education Program, National Institutes of Health, and American Heart Association since the Lipid Research Clinics-Primary Prevention Program in 1984, and earlier by the U.S. Department of Agriculture food pyramid, may well have played an unintended role in the current epidemics of obesity, lipid abnormalities, type II diabetes, and metabolic syndromes. This diet can no longer be defended by appeal to the authority of prestigious medical organizations or by rejecting clinical experience and a growing medical literature suggesting that the much-maligned low-carbohydrate–high-protein diet may have a salutary effect on the epidemics in question.

Weinberg reports that the low-fat diet dogma may well have played an unintended role in the current epidemics of obesity, lipid abnormalities, type II diabetes, and metabolic syndromes.
