Dr Mosley will speak at his Wonders of the Human Body event at Civic Theatre on Wednesday night.

Red meat: "I'm OK with meat. I think if you eat it a couple of times a week that's fine. Red meat is a good source of iron."

Bacon: "I love bacon but have it rarely. I don't think it's a terribly healthy thing. Processed meat is not so great."

Butter: "I'm a fan of it. I do think the arguments about saturated fat are overdone, particularly when it comes to dairy. I'm a big fan of full fat yoghurt and things like that. We drink full fat milk these days and we have butter, not huge amounts though."

Margarine: "Hate the stuff. It's a horrible processed food. I try to keep as close as I can to real foods."

Dairy: "Dairy has quite a lot of good stuff in it. The Australian Heart Foundation recently changed its guidelines and said there's no particular benefit from low-fat dairy, so why bother?"

Eggs: "Big fan. I have eggs most days. The idea that eggs are bad for you and increase cholesterol is almost a total myth. They have lots of protein, nutrients and vitamins."

Wheat: "It depends. We know fibre is good for your gut bacteria and microbiome, but it doesn't have to be wheat. I eat oats. Gluten intolerance is on the rise. That's a genuine thing. I love bread so it's very difficult. I tend to go for rye bread and the dark stuff."

Vegetables: "Try and get as rich a variety of colours as you can because those colours all represent different phytonutrients. Now I eat a lot more veg and a lot less pasta and carby stuff."

Fruit: "You're better off eating fruit that's not too sweet. Unfortunately, things like melon and grapes are almost pure sugar. I tend to go for apples, oranges, pears. I eat the whole thing down to the stalk. Most of the goodness is in the skin, obviously not in the case of oranges. With mangoes I also eat the skin."

Sugar: "I try to avoid it. I still have a sweet tooth for chocolate, which is regularly voted the world's most addictive food. I'm yet to shake off my addiction to that."

Chocolate: "There's lots of fibre and good stuff in cocoa. It's the sugary stuff which is not so good. I can eat a square of dark chocolate and not feel the need for more. When I eat the milky stuff, I eat the whole thing and feel terrible afterwards."

Alcohol: "There's quite good evidence around the benefits of red wine in moderation. It seems to be better than any other form of alcohol. It has higher levels of phytonutrients. I wouldn't describe it as a health drink. I have the odd glass of red wine."

Coffee: "I'm a big fan of it. There's lots of evidence that drinking four or five cups a day is quite good for you because of its interesting nutrients. People are very variable in their response to coffee."
