    The programme presenters state there is no mixture of sugars and fats in nature and that we all crave a 50/50 mixture of such.
    Surely this is nonsense?
    Does not milk contain lactose which I always thought was a sugar? Does it not also contain fats?
    It would not surprise me to learn that the mixture in milk was 50/50 and that as we are weaned on milk we have a lifelong craving for this, hence our current problems with obesity.

    Avocado, coconut, milk, durian, bananas, and many other things. So obviously not true.

    and that we all crave a 50/50 mixture of such.
    How would we have evolved to crave something that doesn't exist? That doesn't appear to make sense.

    Sounds like it. I'm sure Horizon used to be quite a good documentary series. The last couple I tried to watch were like music videos with portentous voice overs.

    Does not milk contain lactose which I always thought was a sugar? Does it not also contain fats?
    Indeed.

    I remember reading a fairly persuasive argument from Colin Tudge in The Food Connection. He points out that, for our hunter-gatherer forebears, a craving for high calorie foods like fats and sugars was a good thing.

    To get a good quantity of fat for a group of people, their main option was to crack open an animal's skull to get to the brain and/or the large bones to get to the marrow. To get sugars, they had to make the most of fruit for the brief season when it was ripe or they had to contend with bees to steal honey. So you needed a fairly strong drive to hunt and kill animals. And you needed to gorge on fruit for a few weeks each year and/or be willing to risk life and limb climbing to get to beehives and withstand attack from bees to get honey.

    These strong urges to get high calorie foods helped pre-agricultural, pre-industrial people to get the nutrition they needed. But for us, with all foods easily available, preference for such foods is not such a good thing.

    That makes sense. Sounds like either the Horizon program was totally messed up (they have made some monumentally stupid programs in recent years) or it was presented in a very confusing manner.

    Watching this program last night it seemed to make sense to me.
    One doctor goes on a fat only diet, the other on a sugar only diet. I was expecting them to prove that both are bad for you. I'm a bit addicted to sugar myself, but it turned out that it was quite good for the body, especially when taking exercise which they proved in a cycling challenge where the sugar diet won easily. Even the fat only diet was not so bad, but it did affect mental ability.
    The conclusion was quite startling. We love to eat doughnuts but not all doughnuts are the same. The ones we prefer (the ring glazed type) have a 50/50 mix of fat and sugar. Experiments for this were done in New York and London. Ice cream also has a 50/50 mix of fat and sugar.
    So there you have it - if you want to lose some weight, then its best to avoid these, but I would need to see a long list of items containing 50/50 fat and sugar. And a lot more evidence.

    One thing I forgot. A much, much smaller portion of our populations now engage in hard physical labour. And a lot of hard work is now much less demanding than it used to be. Equipment is used instead or limits are placed on what people do and don't do for health, safety, and insurance reasons.

    But if you think about working at jobs like shearing, laundry, mining, farmhand, roustabout fifty or more years ago - you'd be literally starving if you ate what counts as an adequate diet now. And that would be because your output of calories far exceeded your dietary intake. A big meal of fats and proteins twice a day and a couple of "smokos" where you got a fair sized cake or a sugary bun with your cup of tea would keep you going between meals.
