Science has proven it – rooibos tea is magic

There are very few things more proudly South African than a good cup of rooibos tea. But aside from tasting great with a slice of lemon and a squeeze of honey, rooibos is a globally recognised “superfood” with a surprising amount of health benefits.

Technically speaking, rooibos is a herb, not a true tea.  The brew that many South Africans grew up drinking is considered a tisane (herbal infusion). And like any superfood, it’s full of health-boosting vitamins, minerals, antioxidants, flavonoids and polyphenols (the last two are just fancy words for antioxidants).

A recent study by the South African Medical Research Council (SAMRC) suggests that rooibos may be able to prevent or delay the onset of type 2 diabetes. Type 2 diabetes, according to the American Diabetes Association, causes the blood sugar levels to rise higher than what is considered normal. It also causes insulin resistance which means the body is unable to use insulin properly and over time, cannot produce enough insulin to sustain normal blood sugar levels.

Type 2 diabetes is the most common form of diabetes.

Nireshni Chellan, the scientist who conducted the study, says one in 14 South Africans suffer from diabetes because of poor lifestyle choices. According to Chellan, strokes, blindness and renal failure are some of the more serious complications associated with diabetes.

Rooibos is packed with antioxidants which helps fight type 2 diabetes.

“Antioxidants are said to play a big role in terms of type 2 diabetes, because type 2 diabetes is characterised by high levels of oxidisers and inflammation,” Chellan told EWN.

“We look at mechanistic models that can determine how rooibos actually has antioxidant effects that lead to anti-diabetic effects. We’ve shown glucose lower in capabilities, lipids lower in capabilities and, of course, the antioxidant effect,” she said.

The complex mix of antioxidants in rooibos may also be able to prevent the onset of heart disease. Rooibos contains a heart-health promoting substance called Chrysoeriol. Chrysoeriol is an antioxidant that helps prevent and treat vascular disease (abrupt change of the direction of the blood flow) by slowing the migration of smooth muscle cells inside the aorta – a key cause of the narrowing of the arteries – which could lead to heart attacks. Chrysoeriol is also an effective bronchodilator (a substance that dilates the respiratory tract and increases airflow to the lungs), which helps to lower blood pressure and ease spasms.

A study led by Professor Jeanine Marnewick, specialist researcher at the Cape Peninsula University of Technology (CPUT), showed lower risk of heart disease in adults who drank six cups of rooibos every day for six weeks. Marnewick’s study showed that rooibos reduces total blood cholesterol levels by 10%, and significantly reduced “bad” cholesterol levels.

South Africa’s tea drinking population is 30.9 million strong and rooibos is fast becoming the more popular choice of tea in the country.

A survey conducted by the market research agency Insight Survey, called the South African Tea Industry Landscape Report, earlier this year indicates that more South African consumers are drinking rooibos than the traditional black tea alternative.

For the survey, 25 000 adults in both rural and urban areas were interviewed and it was found that the amount of people who drink black tea drinkers decreased between 2011 and 2015, from 58.6% to 51.5%. On the other hand, the percentage of rooibos consumers grew from 29.4% to 30.9%.

In terms of trade, rooibos is one of South Africa’s most popular exports.

According to the South African Rooibos Council, (yes, there’s a whole council dedicated to the stuff) an average of 12, 000 metric tonnes of Rooibos is produced in South Africa every year. Between 4,500-5,000 tonnes of rooibos is consumed by South Africans, the rest is exported.

Rooibos is a trademarked product and South Africa exports it to more than 30 countries worldwide. Council director Ernest du Toit told EWN that trademarking the product created better exposure of South Africa to international markets.

“Germany and Holland are already together consuming probably more than South Africa is but it’s also popular in the United States, Japan and other countries in the Far East,” said du Toit.

Due to its increasing global demand, exports for rooibos increases by about 6, 000 tonnes each year, so it’s great  for our domestic markets. It provides income and employment to over 5, 000 people and earns an estimated R500 million every year.

Rooibos is native to the Cederberg region of South Africa and has been harvested by the Khoisan for centuries.

According to the South African Rooibos Council rooibos is an all natural product containing no additives, colourants or preservatives. It is naturally caffeine free and – the best news – is that rooibos has no calories.

With its mildly sweet and fruity flavour, its soothing herbal smell and distinct red colour, there is nothing quite like rooibos tea.

    In July of 2016. it was discovered that I got type 2 diabetes, By the end of the July month. I was given a prescription for the Metformin, I stated with the ADA diet and followed it completely for several weeks but was unable to get my blood sugar below 140, Without results to how for my hard work. I really panicked and called my doctor. His response?? Deal with it yourself, I started to feel that something wasn’t right and do my own research, Then I found Lisa’s great blog (google ” HOW NOW I FREED MYSELF FROM THE DIABETES ” ) .. I read it from cover to cover and I started with the diet and by the next morning. my blood sugar was 100, Since then. I get a fasting reading between the mid 70s and 80s, My doctor was very surprised at the results that. the next week. he took me off the Metformin drug, I lost 30 pounds in my first month and lost more than 6 inches off my waist and I’m able to work out twice a day while still having lots of energy. The truth is that we can get off the drugs and help myself by trying natural methods….
