A steak has roughly 21g of sat fat per serving, though. So you'd have to eat 7 bags of Doritos to eat the equivalent of a steak.

My point is not that Doritos aren't bad for you but that saturated fat isn't the reason they're bad

Yes. But they aren't good for you either. They're digestive spam. And as a result the body will continue to seek the nutrition it needs. Feed it more unnecessary calories and it will keep looking.

Eventually, "you are what you eat" catches up to you.

No disagreement here. As I said, it's not that they aren't bad, it's that saturated fat isn't the reason they're bad. I'm with you that doritos should be nixed from any person's regular diet

I'm more fearful of sugar and simple carbs than sat fats.

So.. how much is a serving? Wherever I eat steaks that seems to vary wildly. In any case the variation is too big to warrant giving such a precise number (21 grams) for the amount of fat.

The fun size bags have one serving, but even so I doubt that doritos, en masse, are to blame for obesity. It's the accompanying sedentary lifestyle that is the real culprit.

If we want a food source to blame, look at high sugar content foods like soda or the slew of 'Little Debbie' type snacks (I'm preferential to Nutter Butters) that can be consumed in one or two sittings if you aren't calorie conscious.

But, just to reiterate what's important, if we all just got a solid hour of exercise each day the rate of cancer and heart disease would drop appreciably.

> if we all just got a solid hour of exercise each day the rate of cancer and heart disease would drop appreciably.

But people really want a magic bullet, "X is bad, Y is good". People generally do not like to exercise so they'll keep looking for something else.

Conversely, junk food companies love to shift the blame to the consumers not getting enough exercise.

I don’t disagree that the sedantary lifestyle is the primary cause. However the processed food industry is a dangerous trap; Doritos and their ilk are almost as dangerous as those other sugary snacks, they are just a different kind of addictive, using fats, salt and MSG instead of sugar
