I had never thought of writing about this topic until a friend asked about it during one of the events I attended over the weekend. It was then I knew there could be many more people out there who do not know which is best for them to consume and the main differences or similarities between the two vegetables. It is important to state that it is erroneous to call them tubers just because of their resemblance to yam particularly sweet potatoes.
In some countries, the Irish potato is called white potato and there has been endless argument about which of the two vegetables is healthier for consumption either for the young or old. Potatoes, whether Irish or not, are generally a good inclusion into our diets. So, it is critical for you to note that either of both will improve your overall nutrition.
The chemical composition of both vegetable remains a tool that can make us see the nutrient levels in both veg. One area people are quite particular about is the amount of calories as most people seem to be on the train of losing some pounds o flesh. While sweet potato provides 90kcal per 100gram, Irish provides 93kcal per 100gram……making both vegetable close in calorie value. There is really no need to consider this factor when choosing which one to consume.
In the same amount of serving, both vegetables contain the same amount of carbohydrate with sweet potato containing about 3.3g of fibre in a 100g serving while Irish potatoes contains only 2.2g of fibre in the same 100g serving; making potatoes a good diet for people particularly children who have digestion issues.
The fat and protein content also are of similar levels. In both veg, there are no fat but they both contain some amount of protein. A 100 g serving of Irish potato contains 2.5 g of protein and the sweet potato contains 2 g of protein. In the case of vitamins, sweet potatoes provides more amount of vitamin A and C compared to Irish potatoes while Irish potato provides more amount of mineral (Iron and Potassium) than sweet potatoes.
For me, it is really a difficult one to determine which one is healthier in both as the two foods have their strengths and are majorly similar in some nutrients content. Depending on what health condition you are trying to treat or manage, one of the two foods may appear more appropriate for your situation. However, it does not render the other as less healthy or not healthy for consumption.
