⚠️ Watch-outs & how to enjoy it better
The high natural sugar and carbohydrate content can cause blood sugar spikes, especially when eaten alone or in large portions. To counteract this, pair sweet potato dishes with a source of protein (like beans or chicken) or healthy fat (like olive oil or nuts) to slow digestion, and practice portion control. Also, boiling or steaming instead of frying can help manage calorie intake.

FAQ
Are sweet potatoes and yams the same thing?
No. In the U.S., the terms are often used interchangeably, but true yams are a different, starchier tuber from Africa and Asia. Most 'yams' in American supermarkets are actually orange-fleshed sweet potatoes.
Is the skin of a sweet potato edible?
Yes, the skin is edible and nutritious, especially when the potato is baked or roasted. It adds fiber and texture. Just scrub it well before cooking.
How should I store sweet potatoes?
Store them in a cool, dark, well-ventilated place (like a pantry) for up to a month. Do not refrigerate raw sweet potatoes, as the cold can alter their texture and taste. Once cooked, refrigerate leftovers in an airtight container for up to 5 days.
