OK got it, So technically PHE are correct about that, but give the inference they are all harmful.Eh? please explain this.

Red meat provides a small amount of naturally occurring trans fats in the form of trans-rumenic acid and trans-vaccenic acid. This type of trans fat is actually beneficial and not the same as the artificial trans fats resulting from hydrogenation and used in the food manufacturing industry. Both of these natural trans fats are categorized as omega-7 fats and can help promote healthy cholesterol levels by lowering LDL, or bad cholesterol. In addition, trans-rumenic acid is a form of conjugated linoleic acid, also known as CLA, which is associated with weight control and also found in cows milk.
endquote.
Omega 7 are classed as unsaturated, or monounsaturated, not trans fats, from the bonding.I can't actually understand why they come to that conclusion, as a trans fat is specifically the bonding, which is the issue.
My inference was that because so many manufacturers have reformulated their products, the main sources of trans fats in the diet are now the small percentage that are in butter, beef and lamb fat, whereas previously the main sources were products containing partially hydrogenated vegetable oil. (I must admit, that was news to me - I thought partially hydrogenated vegetable oil was still winning.)OK got it, So technically PHE are correct about that, but give the inference they are all harmful.

I've been trying to understand why you thought someone from PHE had said that all animal fats were trans fats. There is no way that anyone with a basic knowledge of nutrition would think that, let alone an expert from a public body. I wonder if it's because you hadn't realised that animal fats actually consist of a mixture of different fats. The different fats have different chain lengths, different degrees of branching within the molecule and different degrees of saturation (double bonds), all of which affect their properties. A small percentage of the fats present in the animal fat mixture are trans fats.
Naturally-occurring trans fats are still thought to be potentially harmful but in the normal UK diet, the amount of trans fats consumed does not exceed the recommended maximum so they're unlikely to be a problem for most people. However, if someone following a high fat diet relies extensively on animal fats, they might exceed the UK Scientific Advisory Committee's recommended maximum intake that trans fats form no more than 2% of food energy intake.

I have already agreed that point.I can only see this reference
'The only remaining sources of trans fatty acids in the UK diet are butter, beef and lamb fat. '
Which is most likely true.
The fats listed contain an amount of trans fats, but they are mainly saturated fats.
Artificially made vegetable trans fats have been (mostly) banished from the foodchain now.
(Although a lot of people still like to incorrectly use them as a scare tactic when arguing over animal fats.)
I have already agreed that point.
Most Cholesterol is made in the liver, you need it to produce vitamin D.Reports or no reports, it stands to reason, cholesterol clogs arteries, fact, (I should know after a quintuple bypass), cholesterol comes from animal fat. I'm sorry but it doesn't need studies or a nutritionist to connect those dots.
The following has been copied from an article written by Alison Tedstone on the PHE website:I don't see where you're getting the 'all animal fats are trans fats' from?
The quote states there are some trans fats in animal fats, not that all animal fats are trans fats.
It also states that is the only place they now enter the food chain.
Possibly you are reading it differently?
You also need it to transport essential amino acids to the cells. Without cholesterol we die.Most Cholesterol is made in the liver, you need it to produce vitamin D.
Cholesterol is indeed necessary for life - it is an essential component of cell membranes, and a precursor for steroid hormones, vitamin D and bile acids. Fortunately we can manufacture it in our livers.You also need it to transport essential amino acids to the cells. Without cholesterol we die.
Can you provide a link to the PHE report regarding bariatric surgery, please?The following has been copied from an article written by Alison Tedstone on the PHE website:
The majority of trans fat in UK diets comes from natural sources in meat and milk. We know trans fats are harmful to health, but in the UK average consumption is already well within maximum recommended levels and is falling.
This is not the quote I have been looking for, but it is from the same website that her other blog was found on. I cannot find it now, and Alison is no longer listed as an author in the blogs section.
It seems clear that PHE are certain that all transfats are harmful, and by inference, since they are found in meat and dairy, then this is a reason for restricting consumption. They have not recognised that the natural Omega-7 transfats may actually be beneficial, but lump them all on the naughty step.
As an aside, during my research here, I have uncovered two worrying reports released recently by PHE. One is that diabetics should be recommended to have bariatric surgery/ gastric banding as a primary means of control
And, secondly, they have ammended the Eatwell#2 guidance by reducing dairy intake from 15% of RDA to 8% per day. This has the immediate effect that the average woman will exceed this limit just by consuming 1 Latte coffee, or 3 milky coffee's. it is 3 slices of processed cheese max for a man. They have also apparently reduced protein input to 70g max/day
Sorry, i should have said fatty acids. Amino acids transfer in the blood plasma.Cholesterol is indeed necessary for life - it is an essential component of cell membranes, and a precursor for steroid hormones, vitamin D and bile acids. Fortunately we can manufacture it in our livers.
What makes you think it transports essential amino acids?
It was reported on this site yesterday.Can you provide a link to the PHE report regarding bariatric surgery, please?
