If you’re reading this while pondering what to have for breakfast, you might want to think about whole grains, fruit, nuts: something high in fibre. Not necessarily for the good of your colon, but for your brain, your immune system and overall health. Fibre is a dietary health star, and it’s time to stop relegating it to a supporting role as roughage.

Today in The Conversation Canada, Mark Wulczynski of McMaster University writes about some of fibre’s lesser-known benefits, including its function as a prebiotic nutrient, its connection to the gut-brain axis and its role in the immune system.

“Fibres can also have microbe-independent effects on our immune system when they interact directly with receptors expressed by our cells. These beneficial effects may even help teach the immune system to be more tolerant and reduce inflammation.”

It is possible to have surgery to replace the crystalline lens, the natural lens of the eye, with an implant — without having a cataract. But surgery has risks.

En mettant l’accent sur les triomphes tactiques, les erreurs de calcul et les frasques sexuelles de Napoléon, Ridley Scott néglige l’héritage paradoxal qu’il a laissé en tant que législateur.
