Sweet potatoes are a type of root vegetable that are incredibly versatile and nutritious. They have lots of vitamin A, vitamin C, and fibre. What’s not to love? Of course, as a digestive health dietitian, I tend to get questions about whether sweet potatoes are gut-friendly. Let’s chat about the benefits of sweet potato, the FODMAP content of sweet potato, and whether it’s good for those with IBS. Plus, I’m sharing a hearty roasted sweet potato salad recipe that you’ll love!
In this recipe roasted sweet potato is mixed with fresh red pepper and parsley and drizzled with a lemon-dill dressing. All the ingredients accompanying the sweet potato are low in FODMAPs and therefore, calculating a portion size is simple. If you stick to ½ cup or less of this salad you will keep the sweet potato portion to a low FODMAP serving! Therefore, serve on the side of some of your favourite dishes. Perhaps try it on the side of our Low FODMAP Lemon Herb Chicken, or our Low FODMAP Grilled Shrimp!
Have you been trying to do the low FODMAP diet on your own? Feeling overwhelmed? Here at Ignite Nutrition we offer one-on-one nutrition counselling to help you start on the low FODMAP diet with guidance.
Are sweet potatoes low FODMAP?
Yes and no. They are not only nutritious, but low FODMAP, at ½ cup portions, and moderate at 2/3 cup portions! This just means it’s important to keep portions moderate if you follow a low FODMAP diet.
There are a few types of sweet potatoes. One kind has a white interior that is slightly less sweet. The other type has a bright orange interior that has a sweeter taste1. There are also purple sweet potatoes now too! Perhaps, you have tried the sweet orange kind, for example if you’ve ever ordered sweet potato fries. In fact, I thought sweet potatoes were only orange coloured for a long time! I was quite surprised when I peeled the sweet potatoes for this recipe, and they were white.
Are sweet potatoes good for you?
Sweet potatoes are a good source of fibre, magnesium, as well as a high source of Vitamin A.1 Sweet potatoes do contain FODMAPs but are considered low FODMAP if consumed below the low FODMAP portion size of ½ cup.2 Therefore, serving this nutritious vegetable on the side of a meal is a great way to still enjoy the flavour and nutrients from this vegetable without exceeding the low FODMAP serving size.
How to Use Sweet Potato
What I love most about sweet potatoes is how versatile they are. They can be pureed for use in creamy soups, grated on top of salads, made into fries, mashed like potatoes, or even served as a sweeter dish with cinnamon and roasted walnuts. However, my favourite method to cook sweet potato is simply to roast them in the oven. It looks fancy, yet it is a simple method that leaves you with very little dishes to clean at the end. I also find that roasting, and slightly browning vegetables helps bring out their flavours!
