Moisture content? Honestly no idea but now I'm curious too.

It’s because of water content, most likely. A common comparison I used to see was “are you going to get full faster on grapes or raisins?” They’re the same thing basically but one is dried. Because of that it takes up less volume and mass and can fit more compactly in the stomach per calorie

If I understand the summary of this study correctly, eating boiled potatoes doesn't satiate more than eating fries, at least if you use an equal mass of potatoes. The amount of oil increases the amount of calories in the fries a lot though and I can imagine that the shape of the fries makes them look like they're more than they are. Potatoes are big and stack densely, but french fries stack rather loosely, so if you fill bowls of the same size, the bowl with fries will be a lot lighter than that with boiled potatoes.

I feel like it might be the taste too, I don't think most people would as excited to eat mashed/boiled potatoes as they would be for french fries because it doesn't taste as good and perhaps the amount of salt added to the french fries make people crave for more

I’m not entirely convinced the premise is sound. Who is saying this? I imagine if you eat the same amount of each you’d likely feel a similar level of satiety.

Boiled potatoes are very interesting. They contain a lot of starch, but when a boiled potato cools down (i.e. on your plate) then the starch in the potato turns into something called 'resistance starch'.

Resistance starch stays intact more until the intestines where it acts as a fibre for intestinal flora. Cooled rice also has this affect too. I think this sense of the starch keeping form for longer is what's ultimately responsible for the difference. Fibre and starch and proteins keep their forms longer which contribute to a feeling of fullness. Focusing on calories alone doesn't work for example, you can consume a lot of calories in sugary alcohol and not feel full compared to the same calories in food. This is because the drink is more fluid (less fullness) and the calories are absorbed significantly quicker and earlier in the digestive tract.

As others have pointed out, water content, portioning size (small individual chips vs bigger potatoes) also come into it.

Do not fill up on raisins, at least according to my grandfather. A kid he knew did it after a bakery got bombed, and the kid died.

> I don't think most people would as excited to eat mashed/boiled potatoes as they would be for french fries because it doesn't taste as good

I disagree

After some research, I think it's very likely that kid had diabetes (though they probably didn't know it at the time). Eating a ton of raisins means eating a ton of sugar, and that will seriously fuck up a diabetic kid.

I found some indication that eating a ton of raisins can increase your chances of a stroke, but the link seems tenuous and I can't find any dosage information.

Not to suggest you should fill up on raisins if you're not diabetic, not doing that is very good advice regardless of why that kid died.

Sure, if you add enough potatoes to your cream and butter....

So potato salad will keep you feel fuller more quickly than mash?

Carb + fat is hyper rewarding, especially combined with salt or sugar. They mess with your natural satiety system making you eat more.

Depends if the mash has skin in it. The skin has the most fibre and micronutrients. But skin excluded, the mash and boiled potatoes don't differ too much as far as I know.

I disagree. I think boiled tatties feel much more wholesome and appetizing than the puffed up fry.

I appreciate you looking into it. I can't stand raisins myself, so the risk seemed low. But I thought it was worth mentioning.

I'm adding butter and salt to my boiled or mashed potatoes. Who isn't?

me too, French fries taste better with some kinds of meat, during mashed potatoes taste better with Fishsticks and other stuff.

As far as I know it's only the volume of the food that makes you feel full.
That's the reason some people say you should drink a glass of water before you start to eat.

a lot of times fries have MSG added to them, especially at fast food places, so you might be full but you’re not feeling full: that’s the MSG

My 73yo mun, STILL!
