General nutrition thread
I was wondering if we could have a thread which was just about nutrition in general as opposed to being specifically about supplements or what you ate today or whatever. Macronutrient ratios, paleo diets, mediterranean diets, keto diets, anti-oxidants, nutrition biochemistry, food science and technology etc etc. Then the other threads can stay on topic and not get derailed by this stuff.

Anyway the idea for this thread came from something interesting I saw this morning on one of the morning shows. They had a nutritionist talking about different types of fibre. At present it seems as though the nutrition world is awash with studies regarding fibre and health benefits. Anyway the bit that was very interesting that I had never heard about before was that there are 3 different types of fibre: 1. the type that comes from stringy fruits and veges such as asparagus. (she mentioned pectin in apples so it could be this type). 2. the type that is associated with nuts and grain husks. That would be our wholegrains and psyllium etc and 3. there is a type of fibre which aggregates during the cooling process following cooking of starchy carbs such as potatoes and pasta. Hmm very interesting This is supposedly the type of fibre which is mostly missing from a typical (healthy) western diet. So if you cook pasta or potatoes you can let them cool... hey presto potato salad, pasta salads etc etc and then it isn't going to be so insulin spiking as you might think.

Soluble fibre - includes pectins, gums and mucilage, which are found mainly in plant cells. One of its major roles is to lower blood cholesterol levels. Good sources of soluble fibre include fruits, vegetables, oat bran, barley, seed husks, flaxseed, psyllium, dried beans, lentils, peas, soymilk and soy products. Soluble fibre can also help with constipation

Insoluble fibre - includes cellulose, hemicelluloses and lignin, which make up the structural parts of plant cell walls. A major role of insoluble fibre is to add bulk to faeces and to prevent constipation and associated problems such as haemorrhoids. Good sources include wheat bran, corn bran, rice bran, the skins of fruits and vegetables, nuts, seeds, dried beans and wholegrain foods.

Resistant starch - while not traditionally thought of as fibre, acts in a similar way. Resistant starch is the part of starchy food (approximately 10 per cent) that resists normal digestion. It is found in many unprocessed cereals and grains, firm bananas, potatoes and lentils, and is added to bread and breakfast cereals as Hi-Maize. It can also be formed by cooking and manufacturing processes such as snap freezing. Resistant starch is also important in bowel health. Bacteria in the large bowel ferment and change the resistant starch into short-chain fatty acids, which are important to bowel health and may protect against cancer. These fatty acids are also absorbed into the bloodstream and may play a role in lowering blood cholesterol levels.

^^^ is that a cut and paste or off the top of your head?

she mentioned also the bowel bacteria stuff which is another good reason to be not so afraid of carbs.

Sorry, should have linked.

I'm on a pretty intense health kick at the moment, and I'm pretty picky about sources of information I'll actually trust. Does anyone know of a good daily dietary intake estimator? I'm trying to work out (precisely) how much of each different thing I need (particularly fat/saturated fat - at the moment I'm on 60g/15g respectively).

I don't really see any definitive reasons why this can't be covered in the existing threads (like what did you eat), which most of it is, but I'll give you a few posts to change my mind before I lock it

Ive found some good nutritional information on the ausbb forums. A very interesting thread here http://ausbb.com/nutrition-diet/1534...-gi-myths.html called Canning the 6 meals, 'clean' eating, the Post Workout Anabolic Window and GI myths

I've found the "my fitness" app to be pretty good for Australian brands of foods.

the other one is [from memory] Calorie King (Australian) program which has a more comprehensive list of brands/foods.

No one has put up a compelling argument all day so I'm closing this -- if you'd prefer me to rename "what did you eat" to "what did/will you eat" let me know.

Here's a parting slice of nutritional intrigue for you all: http://www.thesun.co.uk/sol/homepage...ed-Claire.html
