Great Post. Thanks for sharing.

I just wondered if you were aware of Nutritional Yeast as opposed to Brewer's Yeast. Its available in UK Supermarkets. I sprinkle it on my food and its full of a broad spectrum of B Vitamins and for Vegan Food it actually tastes really nice.

Top 5 nutritional yeast benefits and how to use it


Also I copied this from NutritionFacts.Org ....



Benefits of Nutritional Yeast to Prevent the Common Cold

Written By Michael Greger M.D. FACLM on February 14th, 2017

Natural immunomodulators that can help regulate our immune system without side-effects have been sought for centuries, and all the while they’ve been sitting in the produce aisle. Plants produce thousand of active compounds, many of which modulate our immune system, but we can’t forget the fungi (see Boosting Immunity While Reducing Inflammation).

Mushrooms have been used for centuries as folk remedies, and for good reason. Some have been shown to boost immune function, so much so that a type of fiber found in shiitake mushrooms is approved for use as adjunct chemotherapy, injected intravenously to help treat a variety of cancers by rallying our immune defenses.

More than 6,000 papers have been published on these so-called beta glucans, but almost all of the data about preventing infections had come from petri dish or lab animal studies, until a few years ago when a series of experiments on athletes showed beneficial effects in marathon runners (see Preserving Immune Function in Athletes With Nutritional Yeast). What about the rest of us? We didn’t know… until now.

As I explore in my video, Nutritional Yeast to Prevent the Common Cold, beta glucan fiber found in baker’s, brewer’s, and nutritional yeast helps to maintain our body’s defense against pathogens even in nonathletes, according to a double-blind, randomized, placebo-controlled trial. The recurrence of infections with the common cold was reduced by 25% in those that ate the equivalent of about a spoonful of nutritional yeast a day, and they had fewer cold-related sleeping difficulties when they did get sick.

What about half a spoonful a day? Still worked! Subjects experienced a big drop in common cold incidence and a reduction in symptoms as well. Why is this? This study found that not only were upper respiratory infection symptoms diminished, but that mood states appeared to improve, for example, a significant boost in feelings of “vigor.” So, the researchers suggest that maybe the yeast fiber is able to counteract the negative effects of stress on the immune system.

In terms of side effects, two folks reported stomachaches, but they were both in the placebo group.

Unlike antibiotics and antivirals, which are designed to kill the pathogens directly, these yeast compounds instead appear to work by stimulating our immune defenses, and as such don’t share the same antibiotic side effects. They stimulate our immune defenses presumably because our body recognizes them as foreign. But if it’s treated like an invader, might it trigger an inflammatory response? Turns out these fiber compounds may actually have an anti-inflammatory effect, suggesting nutritional yeast may offer the best of both worlds, boosting the infection fighting side of the immune system while suppressing inflammatory components.
