Investigadores de Israel dicen que alimentos ricos en antioxidantes como el chocolate y los frutos del bosque pueden aumentar el riesgo de padecer el mal.<\/em><\/strong><\/p>\n

Por Abigail Klein Leichman, ISRAEL21c<\/p>\n

Justo cuando encuentras algo para beber y los cient\u00edficos est\u00e1n de acuerdo en que es bueno para tu salud aparece un nuevo estudio que afirma exactamente lo contrario.<\/p>\n

La m\u00e1s reciente y contradictoria informaci\u00f3n se refiere a alimentos ricos en antioxidantes como el t\u00e9 negro, el chocolate amargo y las bayas. Durante a\u00f1os se nos dijo que los antioxidantes protegen las c\u00e9lulas contra la oxidaci\u00f3n causada por los radicales libres, que pueden promover enfermedades card\u00edacas, c\u00e1ncer y otras patolog\u00edas.<\/p>\n

Ahora, un nuevo estudio del Centro Lautenberg de Inmunolog\u00eda e Investigaci\u00f3n del C\u00e1ncer de la Universidad Hebrea de Jerusal\u00e9n publicado en ingl\u00e9s en Nature sugiere que los altos niveles de metabolitos que se hallan en ciertas bacterias y alimentos ricos en antioxidantes ofrecen un entorno \u201cacogedor\u201d para el desarrollo del c\u00e1ncer de colon.<\/p>\n

El profesor Yinon Ben-Neriah y su equipo dirigido por Eliran Kadosh buscaban comprender por qu\u00e9 el 98 por ciento de los c\u00e1nceres intestinales ocurren en el colon y solo el 2 por ciento en su vecino intestino delgado.<\/p>\n

Los cient\u00edficos sospechaban que el microbioma intestinal de bacterias estaba involucrado en los resultados. El intestino delgado contiene pocas bacterias mientras que el colon contiene una gran cantidad.<\/p>\n

\u201cLos especialistas est\u00e1n empezando a prestar cada vez m\u00e1s atenci\u00f3n al papel que desempe\u00f1an los microbiomas intestinales en nuestra salud, tanto sus efectos positivos como, en este caso, su papel a veces perjudicial de ayudar e incitar a la enfermedad\u201d, explic\u00f3 Ben-Neriah.<\/p>\n

Para probar su teor\u00eda, los investigadores introdujeron prote\u00ednas p53 mutadas en ratones que promueven el desarrollo de c\u00e1ncer en el intestino.<\/p>\n

\u201cQuedamos fascinados por lo que vimos. Las bacterias intestinales tuvieron un efecto del tipo \u2018Dr. Jekyll y Mr. Hyde\u2019 sobre las prote\u00ednas p53 mutadas. En el intestino delgado cambiaron totalmente de rumbo y atacaron a las c\u00e9lulas cancerosas mientras que en el colon promovieron el desarrollo canceroso\u00bb, afirm\u00f3 Ben-Neriah.<\/p>\n

\u00bfQu\u00e9 es lo que hay en el microbioma intestinal que hace que el colon sea susceptible al c\u00e1ncer? Los cient\u00edficos creen que se podr\u00eda tratar de antioxidantes.
\nCuando alimentaron a los ratones con una dieta rica en antioxidantes, su flora intestinal aceler\u00f3 el modo impulsor del c\u00e1ncer de p53.<\/p>\n

\u201cEn t\u00e9rminos de la ciencia, este es un territorio nuevo. Nos sorprendi\u00f3 ver hasta qu\u00e9 punto los microbiomas afectan a las mutaciones del c\u00e1ncer, en algunos casos, cambiando por completo su naturaleza\u201d, describi\u00f3 Ben-Neriah, que para finalizar sugiri\u00f3 que las personas con alto riesgo de padecer c\u00e1ncer colorrectal puedan querer examinar su flora intestinal con m\u00e1s frecuencia.\u200b<\/p>\n
