I think the relevant part here, is where they mention the preservatives.
If you go into a supermarket and pick up a pack of cheap ham, it may be only 80% pork and have added water, salt, pork protein, sodium phosphate, sodium polyphosphate, sodium nitrate, dextrose and tapioca starch.
The ham I buy (from Lidl incidentally) is air-dried, produced in the same way in Italy since Roman times and the only additional ingredient is salt.
Cheapest pork sausages in Tesco contain only 43% pork with 8% pork fat, rusk(wheat) potato starch, vegetable protein (soya), guar gum, diphosphates (not specified which), sodium metabisulphate, E300, E307 and cochineal.
I can easily believe that the majority of people in the developed world, eating red meat, are eating burgers, sausages, ready meals and processed meats containing the cheapest meat, unspecified animal protein, additives, preservatives, fillers, colourants i.e. all kinds of junk.
You can't expect to get high quality sausages at 8 for £1.25 for example.
Looking at the cancer charity link, it says that people eating more red meat, may be eating fewer vegetables. Again, that may be true.
When husband and I wiped out bread, pasta, rice etc from the base of the food pyramid, we replaced it with vegetables. From March - September I recorded all food purchases and using the 'this is 1 of your 5 a day' blurbs on a supermarket website, I reckon that I'm getting more like 10 - 15
This news may give the anti-low carb camp more ammunition but whether shoppers get behind it depends on whether the government gets behind it.
Realistically, what are people going to eat more of, if on a budget ?
If you're eating ready meals, burgers, sausages and processed meats because they are cheap, you are likely to cut back on them and eat more carbs not veg, if you take any notice of the WHO advice at all.
It's possible to pick up 2 whole farmed fresh trout in Sainsbury's for 2.25 but so many people cannot cook or get squeamish around fish that fish probably won't get more popular. Besides which we get warned not to eat too much fish, because of mercury.
Sometimes it feels like this world is so polluted and industrialised that all our food is toxic.
