Sweet Potatoes

Sweet potatoes are native to Central America and are one of the oldest vegetables known to man. It is documented that they may have been consumed since prehistoric times as sweet potato relics have been discovered in some Peruvian caves. Christopher Columbus first brought sweet potatoes to Europe after his first voyage to the New World in 1492.

They have a creamy texture with a sweet, warm and a little spicey flavour that makes them ideal for savoury dishes. However they are also great in cakes, cookies, smoothies and even to make ice-cream. Although peak season for sweet potatoes is October to March, they are a vegetable that is readily available, inexpensive, and delicious.

Depending upon the variety, there are around 400 different ones, the skin and flesh of the sweet potato may be almost white, cream, yellow, orange, pink, or deep purple. The Japanese and Korean white/cream and American yellow-orange flesh are most common.

Although sometimes referred to as ‘yams’ in the USA, sweet potatoes belong to an entirely different food family. They are also very different from the common potato. Sweet potatoes are far more nutrient dense and healing. Their properties and uses are diverse, and when you choose sweet potatoes as a dietary root vegetable, you are getting a truly unique and superior type of potato. Some of the benefits include

They are high in vitamin B6. Vitamin B6 helps reduce the chemical homocysteine in our bodies. Homocysteine has been linked to degenerative diseases, including the prevention of heart attacks.
They are a good source of vitamin C. While most people know that vitamin C is important to help ward off cold and flu viruses, few people are aware that this crucial vitamin also plays an important role in bone and tooth formation, digestion, and blood cell formation. It helps accelerate wound healing, produces collagen, which helps maintain skin’s youthful elasticity (sweet potatoes make us look young- bonus!), and is essential to helping us cope with stress. The anti-oxidant properties also may help to prevent cancer.
They contain some Vitamin D which is critical for immune system and overall health at this time of year. Both a vitamin and a hormone, vitamin D is primarily made in our bodies as a result of getting adequate sunlight. Vitamin D plays an important role in our energy levels, moods, and helps to build healthy bones, heart, nerves, skin, and teeth, and may support the thyroid gland.
Sweet potato’s are full of beta-carotene’s good for eyesight, immune system and digestive health.
Sweet potatoes contain some iron. Most people are aware that we need the mineral iron to have adequate energy, but iron plays other important roles in our body, including red and white blood cell production, resistance to stress, proper immune functioning, and protein metabolism, among other things.
Sweet potatoes are a good source of magnesium, which is the relaxation and anti-stress mineral. Magnesium is necessary for healthy artery, blood, bone, heart, muscle, and nerve function.

Another interesting thing about sweet potatoes is the antioxidant capacity of all their parts. Recent research has shown differences in consuming the flesh versus skin of the sweet potato. Both producing different concentrations of anthocyanin antioxidants. Purple-fleshed sweet potatoes (when you can find them- Asia has them fairly regularly) are a fantastic source of anthocyanins (especially peonidins and cyanidins) as the darker and more vibrant the colour of a vegetable the more antioxidants they contain. In one study, the antioxidant activity in purple sweet potatoes was seen to be up to 3 times higher than that of blueberries.

Since they are not actually a potato so therefore not a deadly nightshade, sweet potato can actually have a healing effect on your digestive system rather than an irritating one. The fibres in the sweet potato actually feed the bacteria and are classed as fermentable as a prebiotic (food for bacteria). This therefore helps to create a more balanced bacterial environment in your digestive system. Thus giving a digestive healing effect with an immune boost too.

Finally most kids love sweet potato- it is a great first food, great in the lunch boxes cold and as hot chips at dinner time. A simple way to get some amazing nutrients into kids without too many arguments. Try them in smoothies, juices and soups for a smooth creamy consistency and natural sweetness.
