I've one growing.

Sweet potatoes and white potatoes, to me, are two totally separated foods. Not interchangeable. But that is me. Potatoes are a starch. Sweet potatoes a great alternative to dessert; just crumble a little raw brown sugar and butter on it. But that's me.

I love sweet potatoes but can't grow them where I live.

I’m growing them and started eating then instead of whit potatoes. And the leaves are good in salad.

They have a few more calories per hundred grams - 87 as opposed to 76, so shoyuld be treated with caution on a calorie-controlled diet. If you are not on a diet, they make delicious crisps (US chips) cooked in the oven, lightly sprayed with oil and salted.

I buy them often can't grow them we haven't enough ground !

Yes, I did know that. Also, they are high in potassium, which is essential to heart health. They are high in vitamin C, which is extremely beneficial for healthy skin. They are a good source of magnesium, which is required for every bodily process...every organ. They have a low glycemic index, which means they do not raise blood sugar quickly when ingested (good for everyone, especially diabetics). They are high in beta-carotene, which is converted to vitamin A (Retinol) by the body They are fat free and full of fiber, which aids in lowering cholesterol. They contain Folate, which is an aid to cell growth (which usually slows with aging). AND they aid in collagen growth, which makes your skin glow. I’ve been studying nutrition...food and how our bodies use it and react to it for more than five years now. Sweet potatoes, especially the purple-ish Japanese kind, are a super-power food. And they are the reason I bought an air fryer, so I can enjoy fat-free sweet potatoes AT LEAST every other day.

I have planted a good quantity this year, ,_.50 slips, so I am looking forward to the harvest.
Hopefully several bushels by November.

And useful to diabetics, unlike ordinary spuds.

But, if you hare cardiac problems they are also very high in potassium. Not good.
