Sweet Potato Facts

The sweet potato (Ipomoea batatas) is a dicotyledonous plant belonging to the family Convolvulaceae. Sweet potatoes are one of the oldest vegetables known to mankind. They have roots, whereas regular potatoes are tubers (underground stems)

 

History and Origin

The origin and domestication of the sweet potato is thought to be either Central America or South America. In Central America, sweet potatoes were domesticated at least 5,000 years ago. In South America, Peruvian sweet potato remnants have been dated back as far as 8000 BC.

In one of history's mysteries, Polynesians in the South Pacific were growing sweet potatoes as early as 1200 A.D. In fact, the native South American vegetable was the Maoris’ principle food when Captain Cook first reached New Zealand in 1769.

 


Types of Sweet Potato

Sweet potatos grown and sold in Australia, include;
  • • Beauregar
  • • Northern Star
  • • Wspf
  • • Kestle

 

Beauregard - The Beauregard has a rose/gold smooth skin, with a moderately deep orange flesh. Over 90% of sweet potatoes sold in Australia are Beauregard.

The Beauregard sweet potato is a popular, high-yielding variety with pink to orange skin and deep orange flesh that is known for its sweet flavour and versatility. It is disease-resistant, fast-maturing, and stores well, making it suitable for both commercial production and home gardening. The flesh is often described as juicy and slightly stringy when cooked, making it ideal for mashing, baking, and desserts.

 

Northern Star - The Northern Star has a red purple skin, with bright, white flesh. This is the second most popular sweet potato in Australia with around 8% of sales.

The Northern Star sweet potato is a variety with a red or purple skin and creamy, white, nutty-flavoured flesh. It is the second most popular sweet potato in Australia, known for its firmer, drier texture compared to the more common orange varieties. Both the tubers and the leaves (which can be eaten like spinach) are edible. 

 

WSPF - The WSPF has a white skin with white and purple flesh. Around 2% of Australian sweet potato production is devoted to WSPF

WSPF stands for White Skin Purple Flesh sweet potato, a variety known for its white skin, purple and white flecked flesh, and slightly sweeter taste. It's suitable for various cooking methods like salads, baking, and mashing, and is notable for its high levels of antioxidants like phenolics and anthocyanins. 

 

Kestle - The Kestle has a white skin, with cream to white flesh. Only small amounts of this sweet potato are grown in Australia.

The Kestle variety of sweet potato is a white-skinned, white-fleshed type that has a mild, slightly nutty, and subtly sweet flavour. It is less sweet than common, orange-fleshed sweet potatoes and has a drier, more starchy texture.

Sweet Potato Health Benefits

Sweet potatoes are nutrient-dense, offering antioxidants, fiber, vitamins (A, C, B6), and minerals (potassium, copper) that support vision, immune function, gut health, heart health, and stable energy, while also having anti-inflammatory properties that help manage blood sugar and protect against chronic diseases like cancer and heart disease. Their rich beta-carotene, polyphenols, and anthocyanins contribute to these extensive benefits, making them a healthier complex carbohydrate than many other starches.

 


  • RICH IN VITAMINS AND MINERALS
    Sweet potatoes are rich in vitamins, minerals, and antioxidants like beta-carotene (which the body converts to vitamin A), vitamin C, and potassium. They are also a good source of manganese, B vitamins, and fiber, contributing to overall health, including vision, immunity, and heart function.
  • GOOD FOR YOUR CARDIOVASCULAR SYSTEM
    Sweet potatoes are good for your cardiovascular system due to their high potassium content, which helps manage blood pressure, and their fiber and antioxidants, which support heart health. The potassium aids in excreting excess sodium, reducing blood pressure and easing the pressure on blood vessels. Fiber helps lower cholesterol, and antioxidants, like beta-carotene, help protect against cardiovascular disease.
  • HELPS MANAGE BLOOD SUGAR
    Sweet potatoes can help manage blood sugar due to their high fiber and antioxidant content, which slows sugar absorption and improves insulin sensitivity. However, since they are a starchy carbohydrate, it is important to eat them in moderation, be mindful of portion sizes, and choose healthier cooking methods like boiling.
  • SUPPORTS BRAIN FUNCTION
    Sweet potatoes support brain function through various nutrients like beta-carotene (vitamin A), vitamin C, and anthocyanins, which act as antioxidants and provide stable energy. These compounds protect brain cells from damage, improve memory, and help maintain steady energy levels for better mood and cognitive performance.
  • PROMOTES HEALTHY SKIN
    Sweet potatoes promote healthy skin by providing essential nutrients like beta-carotene (which converts to vitamin A) and vitamin C, which support skin repair, protect against sun damage, and boost collagen production. The antioxidants in sweet potatoes also protect skin cells from damage caused by free radicals and inflammation, contributing to a more radiant complexion and helping to prevent signs of aging like wrinkles.

HEALTH
  • POWERFUL ANTIOXIDANTS
    Sweet potatoes are packed with powerful antioxidants, primarily carotenoids (like beta-carotene), anthocyanins (especially in purple varieties), and phenolic acid, which help protect against cellular damage and reduce inflammation. These antioxidants support overall health by contributing to eye and heart health, brain function, and a reduced risk of certain chronic diseases.
  • HELPS KEEP EYES STRONG
    Sweet potatoes help keep eyes strong because they are rich in beta-carotene, which the body converts to Vitamin A. This nutrient is crucial for vision, especially in low light, and helps prevent dry eyes, cataracts, and macular degeneration. Sweet potatoes also contain vitamins C and E, which are antioxidants that protect eye cells from damage.
  • SUPPORTS DIGESTIVE HEALTH
    Sweet potatoes support digestive health due to their high fiber content, which promotes regularity and prevents constipation. They also contain resistant starch, a prebiotic that feeds beneficial gut bacteria and helps produce short-chain fatty acids that reduce inflammation and support gut health. Additionally, sweet potatoes contain antioxidants that may protect against colon cancer.
  • MAINTAINS NORMAL GROWTH AND DEVELOPMENT
    Potatoes support normal growth and development by providing essential vitamins and minerals like vitamin A, vitamin C, magnesium, and manganese. These nutrients are crucial for everything from bone health and immune function to cell division and metabolism. They also contain fiber, which supports digestive health.
  • ANTICANCER PROPERTIES
    The anticancer activity of sweet potato extracts is believed to be driven by their high levels of bioactive compounds, particularly polyphenols and anthocyanins. These compounds are known to induce cell cycle arrest and promote apoptosis (programmed cell death) in cancer cells.
