¿Qué son los polialcoholes y si son seguros de consumir?
2024-12-08
Los polialcoholes han tomado un lugar prominente en la actualidad, ya que pueden ser una alternativa valiosa para reducir el consumo de azúcar en la dieta. Sin embargo, es esencial tomarlos con moderación.

Descubre los beneficios y riesgos de los polialcoholes en la alimentación.

Características de los polialcoholes

Los polialcoholes se metabolizan en el intestino delgado. El cuerpo los absorbe de manera incompleta y gradual. La parte absorbida llega al torrente sanguíneo, donde se utiliza como energía para los diversos procesos celulares. Los residuos que no son absorbidos pasan al intestino grueso, donde las bacterias los fermentan. Estos compuestos aportan sabor, son bajos en calorías (en promedio, la mitad de las calorías que un equivalente en azúcar de mesa) y tienen un índice glucémico menor. Al aumentar progresivamente los niveles de glucosa en la sangre sin un cambio brusco, son populares entre las personas con diabetes. Además, algunos, como el sorbitol, actúan como humectantes y ayudan a retener la humedad de los alimentos y aportar volumen, lo que es útil en la fabricación de productos de panadería. También tienen una acción anticaries y producen una sensación de frescura en la boca cuando se agregan en gran cantidad a un alimento.

Los polialcoholes son varios y dependiendo del azúcar de donde se derivan, toman nombres diferentes y varían en su aporte calórico, dulzor e índice glucémico. El índice glucémico se considera bajo si está entre 1 y 55, por lo que todos los polialcoholes están en ese rango.

Efectos de los polioles en el organismo

Los polialcoholes aportan una menor cantidad de calorías y carbohidratos al cuerpo. Además, producen un cambio menos brusco de los niveles de azúcar en la sangre. Algunos, como el isomaltol, podrían tener un efecto probiótico, aunque esto aún está en investigación. Sin embargo, la absorción lenta tiene efectos negativos, especialmente en el intestino grueso. Si se consumen en exceso o si la persona es sensible a ellos, puede presentarse lo siguiente: otro riesgo es que aumente la posibilidad de sufrir un ataque cardíaco o un accidente cerebrovascular. El eritritol y el xilitol, por ejemplo, pueden hacer que la coagulabilidad de la sangre aumente.

Además, aunque son mejores que el azúcar en términos calóricos (tienen entre cero y dos kilocalorías por gramo frente a los cuatro kilocalorías del azúcar de mesa) y en el índice glucémico (que oscila entre 0 y 35 frente al 65 del azúcar de mesa), son menos dulces. Por ello, en la fabricación industrial, se suelen combinar con otros edulcorantes. También tienen un efecto laxante, lo que es un aspecto a tener en cuenta.

¿Engordan?

La respuesta a esta pregunta no es clara. Las personas que quieren bajar de peso a menudo utilizan polialcoholes para reducir calorías en sus comidas. Sin embargo, si se consumen en exceso, también puede aumentar el peso. Consumir entre 10 y 15 gramos de polialcoholes al día es seguro, pero superar esas cantidades puede traer efectos adversos, como los que ya hemos mencionado.

¿Quién no debería comerlos?

Las personas con enfermedades gastrointestinales, como el síndrome del intestino irritable o la enfermedad de Crohn, no deben consumir polialcoholes, ya que pueden incrementar sus síntomas. Tampoco es recomendable que los niños pequeños los ingieran, a menos que lo autorice su pediatra.

¿Qué alimentos contienen polialcoholes?

De forma natural, estas sustancias se encuentran en algunos alimentos en pequeñas concentraciones, como frutas y verduras. También hay polialcoholes fabricados industrialmente a través de la fermentación o hidrogenación de almidones. Estos se agregan a otros productos durante la fabricación y pueden usarse solos o en conjunto con otros edulcorantes no nutritivos. Algunos alimentos procesados que los contienen son dulces, bebidas y productos de panadería.

En resumen, los polialcoholes pueden ser una alternativa valiosa en la dieta, pero deben tomarse con moderación. Son una buena opción para quienes desean reducir el consumo de azúcar y carbohidratos, pero también se deben tener en cuenta sus posibles efectos adversos. Una alimentación saludable y equilibrada es esencial al consumirlos.

Trump's "Concepts of a Plan" for Healthcare vs. Kristen Welker's Push
2024-12-08
During an exclusive interview on Sunday morning's edition of NBC's Meet the Press, President-elect Donald Trump faced tough questions from anchor Kristen Welker about his healthcare plans. Months after his infamous "concepts of a plan" phrase from the disastrous debate performance, Trump was pressed to provide more details.

Trump's Healthcare Stance Under Scrutiny

Trump's Response to the Healthcare Question

When asked if he had an actual healthcare plan, Trump replied that he had "concepts of a plan that would be better." He emphasized that Obamacare was a disaster and that there were better answers. Trump stated that he had the biggest healthcare companies and doctors looking at it, and if a better plan emerged, he would present it. However, he also admitted that he didn't know when the fully developed plan would be shown to the public.

When asked about coverage for people with preexisting conditions and guaranteeing their prices wouldn't go up, Trump said the answer was yes. He expressed his desire to have better healthcare for less money and believed there were ways to achieve it. He had the smartest people in the healthcare world looking at it and trying. But he also acknowledged that it might not be sellable.

Trump also defended his actions regarding Obamacare. He claimed that he made it workable and that it had insured 20 million people. He said that if he had repealed and replaced it, they would have had a better system, and the Democrats would have been forced to do something.

The September Debate and Memorable Moments

Trump and Vice President Kamala Harris met on the debate stage in September, generating many memorable moments. One of the most notable was Trump's response when moderators asked about his healthcare plan. His answer of "I have concepts of a plan" became a punchline.

This incident highlighted the ongoing debate and uncertainty surrounding Trump's healthcare stance. It showed that despite his claims of having "concepts," there was still a lack of a clear and detailed plan.

The interview with Kristen Welker provided an opportunity for Trump to clarify his positions and address the concerns of the public. However, it also raised more questions about the future of healthcare under his administration.
