Re: Flaw in the argument
"I saw Mr Oliver on telly feeding his young a very healthy breakfast of various bits of tasty fruit. Back of the envelope tells me that was over £4 of fruit each. That's £240 a month for two kids or £360 for three. These are not amounts that the majority of the UK could easily afford for a total food bill, let alone just the kids' breakfasts. Good quality protein is similar - compare the prices of mass produced burgers with even fairly cheap cuts of beef."
If your food bill is too high, you need more imagination, not a fix of junk food.
In-season fruit bought from a market stall is dirt cheap. Out of season or exotic fruit bought from a supermarket is extremely expensive and often tastes worse.
Vegetables are generally healthier than fruit (less sugar), and are even cheaper. Carrots, swede, beetroot, parsnips, cabbage, broccoli, onions, kale, spring greens are massively nutritious and are always cheap. Peas, green beans, tomatoes, peppers aubergine, courgettes, marrow, squash are equally nutritious and are cheap for much of the year.
Lentils, beans, eggs, tuna, mackerel, chicken thighs, pork are all cheap sources of high quality protein. Roasting joints of most meat are also economical unless you pig out. Braising joints are even cheaper and often taste better (slow cookers cook less than £20 these days).
Potatoes, brown rice, brown pasta, home-made wholemeal bread (bread makers are cheap) are dirt cheap sources of very healthy carbs. Porridge is probably the healthiest breakfast cereal available; it's also the cheapest.
A diet based on those ingredients would cost significantly less than one based on ready meals, crisps, biscuits, cakes, and trashy snacks. It would also be healthier and tastier.
Anyone who claims they're too poor to eat well is lying. The truth is probably that they're too lazy to cook and they're looking for an excuse.
"...shoes that are good enough to give you 6 months of injury-free jogging most certainly are not"
You don't need expensive running shoes; research suggests that cheap shoes are less likely to cause injury. You can buy a full set of running gear including shoes from Aldi for less than the cost of one month's gym membership.
Anyone who claim's they're too poor to exercise is lying. The truth is probably that they're too lazy and looking for an excuse.
