OBJECTIVE: To compare the effects of a 1-year intervention with a low-carbohydrate and a low-fat diet on weight loss and glycemic control in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS: This study is a randomized clinical trial of 105 overweight adults with type 2 diabetes. Primary outcomes were weight and A1C. Secondary outcomes included blood pressure and lipids. Outcome measures were obtained at 3, 6, and 12 months. RESULTS: The greatest reduction in weight and A1C occurred within the first 3 months. Weight loss occurred faster in the low-carbohydrate group than in the low-fat group (P = 0.005), but at 1 year a similar 3.4% weight reduction was seen in both dietary groups. There was no significant change in A1C in either group at 1 year. There was no change in blood pressure, but a greater increase in HDL was observed in the low-carbohydrate group (P = 0.002). CONCLUSIONS: Among patients with type 2 diabetes, after 1 year a low-carbohydrate diet had effects on weight and A1C similar to those seen with a low-fat diet. There was no significant effect on blood pressure, but the low-carbohydrate diet produced a greater increase in HDL cholesterol.

The hypertriglyceridemic waist phenotype versus the National Cholesterol Education Program-Adult Treatment Panel III and International Diabetes Federation clinical criteria to identify high-risk men with an altered cardiometabolic risk profile. Metabolism 2009;58:1123-30 Nueva!

In this article, the hypertriglyceridemic waist phenotype (waist circumference ≥90 cm and triglyceride levels ≥2.0 mmol/L) is compared to the National Cholesterol Program-Adult Treatment Panel III (NCEP-ATP III) as well as to the International Diabetes Federation (IDF) clinical criteria to identify white men (n=272) at increased cardiometabolic risk. Prevalence values of men with the NCEP-ATP III criteria, the IDF criteria or the hypertriglyceridemic waist phenotype were 59.2%, 64.0% and 51.1%, respectively. The majority of men with the hypertriglyceridemic waist phenotype also met the NCEP-ATP III (82.7%) or the IDF criteria (89.2%). Men with the hypertriglyceridemic waist phenotype were characterized by small low-density lipoprotein particles, increased apolipoprotein B and insulin levels as well as reduced adiponectin concentration. Similar alterations in cardiometabolic markers were observed in men meeting the NCEP-ATP III and IDF criteria. In conclusion, these results show that these 3 screening approaches are useful to identify individuals with altered cardiometabolic risk profile. However, the hypertriglyceridemic waist phenotype is simpler to use than the two other approaches.

Sedentarismo, dieta y tabaquismo
Las costumbres argentinas no son saludables.
El riesgo cardiovascular del país es el más elevado de la region.
Los médicos se quejan. Dicen que los argentinos comemos mal, que hacemos poca actividad física y que estamos demasiado expuestos al humo del tabaco. Y lo malo es que razón no les falta.
Los estudios y las estadísticas muestran que la dieta de los argentinos presenta un déficit del 58% de alimentos de alto valor nutricional; que el 46,2% de los adultos lleva una vida sedentaria, y que el 33,4% del mismo nivel poblacional fuma, aunque es el 56,7% de la población el que está expuesto al humo del cigarrillo.

La ingesta de verduras durante la gestacion podria proteger al neonato de diabetes.
Según concluye un estudio llevado a cabo por investigadores de la Universidad de Gotemburgo (Suecia) y publicado en la edición digital de la revista Pediatric Diabetes (10.1111/j.1399-5448.2009.00563.x), la ingesta diaria de verduras durante el embarazo protege al niño de desarrollar diabetes tipo 1.

Los jugos de frutas naturales engordan como las gaseosas
Pueden tener incluso más calorías, porque un vaso concentra el azúcar de varias frutas.
Los jugos de fruta cuentan con una muy buena imagen, asociada a la buena salud y a la idea de que su consumo diario es parte fundamental de una dieta adecuada. Pero según coinciden muchos especialistas, el jugo de frutas 100% natural encierra los mismos riesgos para la salud --relacionados con la obesidad-- que las gaseosas.
Un vaso de jugo concentra el azúcar de varios trozos de fruta. Contiene más calorías que una gaseosa común, aunque tiende a ser consumido en porciones más chicas. Un vaso de jugo de tres naranjas tiene aproximadamente 112 calorías y un vaso de jugo de tres manzanas 114, según el Departamento de Agricultura de EE.UU. La misma cantidad de Coca-Cola tiene 97 calorías y de Pepsi 100. Y las gaseosas "sin azúcar" tienen cero calorías.
