Potato Power – Why you should eat more potatoes!

The humble potato – a vegetable that pretty much all of us grew up eating. Whether it is mashed, baked, boiled or sautéed, the potato is a staple around the globe. But somewhere along the way, the poor old reliable potato got a bad rap.

Concern over High Glycemic Index Foods

Potatoes contain a large amount of starch that can raise your glycemic index (GI). The GI is a measure of how quickly a food converts to glucose. When foods convert quicky to glucose, they cause a spike in insulin levels, which increases the risk of diabetes and heart disease.

However, the problem with the GI is that it is calculated based on eating a food in isolation, which we rarely do. What is more relevant is what happens when you eat potatoes with other foods. By adding some healthy fat or protein, keeping the skins on, or eating another fibre-rich food, the GI is significantly lowered. Cooking and cooling your potatoes also reduces the GI. Sorry guys – unfortunately French fries and chips do not have the same effect!

This may present itself differently in different people. An elimination diet or gut reset is a great way to see of potatoes are a problem. Never assume that you have an allergy or sensitivity to a food without testing it! You don’t want to lose that variety if you don’t have to.

Raw Potato Starch

Raw potato starch is the newest supplement to hit the market. It isn’t actually that new though. Potato starch has been used to thicken sauces, soups, and stews for years. It is easy to add into things since it is very neutral tasting.
