Canibais e Reis

Acabo de descobrir este blogue, o NephroPal - Nephrology from a Paleolithic standpoint, que é mantido por um médico nefrologista americano, o Dr. Kenneth Tourgeman. Para quem não sabe, "Nefrologia é a especialidade médica que se ocupa do diagnóstico e tratamento clínico das doenças do sistema urinário, em especial o rim." Trata-se de um blogue relativamente recente, com ideias muito boas no que respeita a estilo de vida e saúde. O Dr. Tourgeman tem como referências, por exemplo, o blogue do cardiologista Dr. William Davis, o Whole Health Source e o Animal Pharm. O NephroPal é blogue científico de qualidade, mantido por um médico da especialidade, já com muita informação sobre variadíssimos temas. Em minha modesta opinião, está muito bom, suportado por um paradigma evolucionário. Ah, e eu já disse que este Doutor não acredita naquela estória das gorduras saturadas entupidoras de artérias? Por tudo isto, recomenda-se! No que ao Canibais e Reis respeita, já conquistou o seu lugar, nas ligações da coluna mais à direita, junto ao blogue do Dr. William Davis.

Saturated Fats (Dr. Kenneth Tourgeman):

 

It seems what we were taught in medical was totally wrong - high saturated fat and low carbohydrate diets promote heart disease. However, the contrary seems to be the truth. A high carbohydrate, high Omega 6 fatty intake (vegetable oils, margarine) is a proinflammatory diet. Well, today’s blog entry on Animal Pharm is a must read (click on the purple text). He sites a study from 2004 showing that coronary artery disease (CAD) may actually be reversed on a high saturated fat diet. What I really liked is that there was LESS progression in CAD in women who were NOT on statins (0.22mm vs 0.09). Moreover, a high saturated fat intake IMPROVED the lipid panel - higher HDL and lower triglycerides. Love my coconut oil.
A high triglyceride level and low HDL is a reflection of high carbohydrate intake. But it gets better. A study from Tel Aviv University showed a higher risk of vascular disease with a high carbohydrate diet. 54 overweight/obese non-diabetics were placed on morning meals of glucose (highest glycemic load), cornflakes (lower), or high fiber cereal (lowest) after an overnight fast. Measurements of the brachial artery flow were measured pre- and post meals. The results showed that 2 hours after the meal, the dilation of the brachial artery was decreased but "was reduced 2 h post-prandially in all groups, showing statistical significance in only high-glycemic index meals."
Thus it appears that high glucose intake decreases the amount of Nitric Oxide which is the chemical responsible for dilation. Studies by Richard Johnson, MD have shown that high fructose consumption increases serum uric acid levels which then in return chelates Nitric Oxide.
