Description

CBC Nature of Things: It Takes Guts (close captioning avail.) https://www.cbc.ca/player/play/2678011123 Start at beginning of the documentary. 1. What is the “microbiome”? - Microbes living inside and on us (skin, mouth and gut) - ecosystem with gut flora that have a specific role to play - some produce nutrients - some break down foods and make energy - 100 trillion bacteria in our bodies - having a wide range of species of bacteria is important 2. Describe the relationship between the microbiome and obesity? - people and rats that are obese have different communities of bacteria in the gut compared to people and rats that are lean. - Bacteria from obese people and lean people  put into mice bacteria from obese people made the mice obese - Makes you think that microbes are actually causing obesity, not only associated with it. - Obese people have less rich and less diverse microbiomes than lean people - Microbes send messgaes via neutrotransmitters along the vagus nerve  can influence dietary choices Stop at 10:00min Start at 13:00min 18:00min. 1. -

How does our diet influence our microbiome? “junk food” does not make it to the colon, starving the microbiome processed foods full of CHO and sugars, goes right to blood stream deprives microbiome 2 way street- we give them a nice place to live and they break down our foods and provide nutrients.

Start at 19:50min 26:00min 2. What kinds of foods are good for our microbiome? - foods that are made of indigestible fibre- nourish bacteria (prebiotics) - zucchini, artichokes, leeks, lentils, chickpeas start at 27:00min commercial (~28min) 3. how did a short term diet of burgers and fries influence the microbiome and how long did it take Tom’s microbiome to recover? - decrease number of species (6000-3000) - took more than 2 weeks of fibre diet to allow mircobiome to get back to normal. start at 32:25min 38:00min 4. How is antibiotic use and method of birth influencing our microbiome and risk for obesity? - wipes out bad bacteria and good bacteria - increase risk of obesity if treated with Abs by first birthday start at 40 min

1. What are some practical messgaes that we can take away from this documentary - diets don't work - increase gut microbes by eating lots of fibre containing foods, meats that are antibiotic free, unpasteurized diary, 20-30 types of food per week. Christensenella...
