Cauliflower pizza crust seems to be all the rage right now, and while I like cauliflower a lot, I really love sweet potatoes. I decided to get creative in the kitchen and test out a sweet potato pizza crust made from mashed sweet potatoes. This pizza is gluten-free, grain-free, and can be made in just over 30 minutes.
Supplements are great, but if you’re eating a not-so-healthy diet, they aren’t doing you much good. Eating lots of plant-based foods offer up an extra dose of nutrition to help keep you healthy and may even fight or prevent the development of illness.
I chose sweet potatoes as the main ingredient in this sweet potato pizza crust because they pack a hearty punch of vitamin A. While vitamin A is essential for preserving eyesight, it also helps boost your immune system, support bone health, and may even help lower your risk of developing certain cancers.
As you get older, your body will start to slow down and deteriorate—and this includes your eyesight. You may be surprised to learn that you can slow that process by making sure you’re getting proper nutrients from the foods you eat.
One of the first vitamin A deficiency signs can be night blindness (also known as nyctalopia). Vitamin A is a fundamental component of rhodopsin, which is a pigment found in the retina that is extremely sensitive to light. 
If you suffer from night blindness, chances are you can still see normally during the day; however, because your eyes struggle to pick up light at lower levels, your vision is reduced at night.
Age-related macular degeneration is another common eyesight concern; it’s actually the leading cause of blindness. Oxidative stress damages the cells and quickens this process. Vitamin A acts as an antioxidant and helps fight free radicals by reducing oxidative stress, which lowers inflammation. [2, 3, 4]
Many people think that cassava flour and tapioca flour are the same; however, that isn’t true. Tapioca flour and cassava flour are from the same plant, but different parts of the plant. Tapioca is used more as a thickener, whereas cassava is used more as an alternative to baking flour—at a one-to-one ratio.
Cassava flour is featured in this sweet potato pizza crust recipe. It's high in vitamin C, which acts as a water-soluble antioxidant. With water-soluble vitamins, excess amounts will be flushed out through your urine and not stored in your body. This reduces the risk of vitamin C overdose/toxicity (which too much of a good thing can be harmful).
A deficiency in vitamin C has been associated with decreased immune function, fatigue, poor iron absorption, poor vision, and weakened bones, to name a few.
The herb arrowroot contains high amounts of potassium, iron, vitamin B-6, thiamin, niacin, magnesium, riboflavin, and vitamin C. Given it's nutritional profile, I knew it had to be included in this sweet potato pizza crust.
Arrowroot is extracted from the roots (or rhizomes) of a plant called Maranta arundinaceaand has been shown to help reduce cell cytotoxicity. Cell cytotoxicity refers to the ability of certain chemicals to destroy living cells. 
Studies conducted on mice and rats in vitro and in vivo concluded these extracts boosted the production of cells, which lead to increased immune function.

Serving Size: 1 slice
1 cup mashed boiled sweet potato
