Are sweet potatoes alkaline or acidic?

As we all continue to figure out what’s good and what’s bad for our bodies, referencing our Acid/Alkaline chart can help make our daily food choices easier. Sometimes though, certain foods are close to the line of being acidic in nature. Even foods that we believe are healthy for us can be acidic.

Are sweet potatoes alkaline or acidic? Let’s learn more about this amazing superfood.

History of sweet potatoes

Sweet potatoes (Ipomoea batatas) are believed to have originated in Central and South America, specifically in the region that now includes parts of present-day Mexico and Central America. Archaeological evidence suggests that sweet potatoes were cultivated by indigenous peoples in these areas as early as 8000 BCE.

These early cultivators developed different varieties of sweet potatoes, which varied in size, taste, and color. The sweet potato’s versatility and ability to grow in a range of climates made it a valuable food source for all.

The history of sweet potatoes is a testament to the resilience and adaptability of this remarkable root vegetable.

Whether roasted, mashed, or incorporated into diverse dishes, sweet potatoes continue to be a beloved and nutritious food source for people around the globe.

What is acidic?

Before we dive into whether sweet potatoes are alkaline or acidic, what does acidic even mean? The pH scale measures the existence of positively and negatively charged hydrogen ions in a specific solution.

Depending upon the composition of a food, when it is consumed, it has an effect on the body’s chemistry. If the net effect is a pH of less than 7, the food is considered acid-forming in the body. Typical acid-forming foods include alcohol, meats, fish, eggs, dairy, and grains.

What is alkaline?

On the reverse side, alkaline food is easier to digest, assimilate, and eliminate without immune burden thus making your immune system happier and healthier.

What is critical to note here is that want to consume more “alkaline forming” foods irrespective of whether the food itself is acidic in nature or alkaline, (e.g., Eating an acidic food, like lime, is actually “alkaline forming” in the body).
