In a change in the last 5 years, I see a lot of protein shakes have collagen protein, even at Pak 'n Save.

Globalnews Canada: Reality check: Is it safe to drink collagen powder?

...According to Villeneuve, there’s a misconception that consuming more collagen will lead to higher quantities of collagen in our bodies, which will make our bones, skin, ligaments and cartilage stronger. This isn’t the case.

'Proteins are synthesized from amino acids. When we consume collagen, we need to first break it down into those amino acids,' ....

That's a pity, because I've been eating oyster shell powder in hope of producing a pearl necklace :)

Collagen powder is a fancier word for gelatine that you make jelly out of. Most likely they add it as a thickener.

I don’t think I’ve ever knowingly had one!

While we're on the subject, cacao nibs are popular in these shakes.

Cacao nibs contain alkaloids, and make them bitter. It's often advertised as being the similar taste as unsweetened chocolate, but I think it's much worse.

I've even seen Cacao nibs and spinach protein shakes, so a double whammy of bitter.

Well it's "derived from" collagen.

If people saw what gelatine is made from I think many would avoid it. Gelatine factories have a certain smell to them, if the raw material is a bit rotten, then it's still ok, pathogens will be boiled to death, the end product will be clean, toxin free, purified.

Last time I had a tour of one, they were using cow face skins as raw material. The dehairing process soaking the cow faces in an alkali solution to break down the keratin makes the collagen in the skin swell up, the stainless steel vessel had glass windows on the side so the operators could see what was going on, every few seconds a bloated swollen and now hairless cow face with holes where its eyes used to be, ears still attached would peer back at you out the window. I guess no worse than the more usual offcuts of skin and hide used as raw material, except instantly recognisable as once the face of an animal, reminiscent of horror movies or bad nightmares.

OTOH the cattle are killed for meat, so using the face skins for something productive is better than throwing it to waste.

Thanks for putting us off innocent jelly. How can any reader eat it again with a cows face skin staring through the mind’s eye. Some things are better kept in the realms of oblivion. I had always consoled myself that it was made from feet/legs.

It "can be" made from cow's faces, that doesn't mean it always is. Things like killing wild sharks for the fins and throwing the other 99% back into the sea is probably a more horrific crime against our planet.

Really not so innocent then is it...? A lot of our food is nowhere near innocent. If people really knew where their food came from and how it was made and what from our diets would be (and arguably ought to be) very different. Like when a small child learns the lamb on their plate is the same as the cute, fluffy thing frolicking in the field.

There is a lot of hocus-pocus BS about food supplements.

Calcium supplements:

You can take calcium supplements - but the body absorbs very little of it.

A glass of regular milk has all the other things that are required for most of the calcium to be absorbed and used effectively.

Omega Oils:
Supplements when tested often have rancid/stale oil of poor quality and tests have revealed that they are not well absorbed.

I piece of Salmon or tinned Sardines are rich in Omega oils and very well absorbed.

Collagen:

(well summed up above) Eating collagen doesn't actually do a lot for you. The body actually needs to build it from scratch to use it.

Vitamin supplements in general:

Many vitamins often require other amino acids or other vitamins in order to be absorbed by the body.

While the odd person may occasionally benefit from some sort of supplements, most people are just wasting money.

Trying to keep a balanced diet appears to be the best bet.

only if the fish you eat had eaten omega rich foods. many European farmed salmon have been called out because they were fed junk and had no omega oils in them. not sure about NZ farmed ones

Possible exceptions:

Vitamin D, particularly in people with darker skin in colder climates, or anybody who doesn't get a reasonable amount of sunlight exposure (which is actually most people in cool climates in winter), and all older people. Wild salmon etc may be a good source of vitamin D, but you'd need to eat a lot - and farmed salmon probably isn't unless they are fed it as a supplement/additive in their now mainly plant-based feed. (We synthesise it via sunlight exposure on our skin, but fish don't synthesise it at all, it's passed up the food chain from plankton).

Iodine - easy to solve with zero risk - use iodised salt.

Vegans need to take special care, there seem to be enough vegans around these days for them not to be considered "just the odd person". Thinking about vitamin B12, iron, calcium and vitamin D intake and considering either supplementation or reading labels and buying and eating fortified foods seems a sensible and reasonable way to avoid complications.

I think farmed salmon is fine for Omega 3 content, there's a question mark over it also having a much higher Omega 6 content as well as having more fat in total.

There's a page dedicated to fatty acid ratios on Wkipedia:

https://en.wikipedia.org/wiki/Fatty_acid_ratio_in_food

It's leading to a huge warren of branching rabbit holes to explore, full of many questions but few definitive answers. Included is ammo for diet fads like "paleo" or whatever you choose, you'll find data to cherry-pick to support just about anything.

Does make me think that *if* Omega 3 : 6 ratio is the important thing, then any Omega 3 supplement tablets would need to be golf-ball sized and supplied in large drums to make any real difference to the average western diet.
