When you’re following this diet, it’s important to know which popular foods are low in FODMAPs and which aren’t. 

For example, let’s think about sweet potatoes. While they’re rich in various nutrients and antioxidants, are there suitable for an IBS-friendly diet?

Fried sweet potatoes aren’t higher in FODMAPs than baked sweet potatoes. But they are higher in calories and fats, as they’re usually fried using butter or cooking oil.

So, if your goal is also losing weight, you might want to stick to oven-baking your sweet potatoes to avoid intaking too many calories from unhealthy fats.

Are sweet potatoes healthy?

Sweet potatoes are a starchy vegetable, so they provide you with a lot of calories from carbohydrates. 

In fact, a one-cup serving of baked sweet potatoes contains 6.6 g of fiber, which equals 26% of your daily recommended need for this nutrient.

Sweet potatoes contain two types of fiber: soluble and insoluble. Soluble fiber absorbs water and helps move food through your digestive tract. On the other hand, insoluble fiber doesn’t absorb water and prevents indigestion.

What’s more, sweet potatoes contain 65% of your daily need for vitamin C in a single serving. 

This micronutrient, also known as ascorbic acid, is important for the growth, development, and repair of all body tissues.

Vitamin C is also crucial for the absorption of iron, the formation of collagen, and the health of your immune system. Because of that, getting enough of this vitamin can help prevent anemia, keep your skin healthy, and fight against viral infections.

Sweet potatoes also pack a great dose of potassium, around 950 mg in a one-cup serving

This mineral is important for fluid balance in your body as well as for offsetting the negative effects of sodium on your blood pressure.

Potassium is also responsible for muscle contractions and nerve signal transmission. So, it’s important to get enough of this nutrient each day.

Just like all other types of potatoes, sweet potatoes contain a lot of powerful antioxidants. 

These plant compounds help protect your cells from oxidative damage, reducing your risk of various chronic conditions like heart disease, diabetes, and even cancer.

What’s more, the antioxidants found in sweet potatoes also have anti-inflammatory properties, which help prevent chronic inflammation and conditions resulting from that.

So, make sure to load up on antioxidant-rich foods.
