Foods rich in carbohydrates have had a very bad rap of late. With the growing popularity of low carb diets, many people avoid high carbohydrate foods entirely or cut back extremely. However, not all carbs are the same and not all food containing carbohydrates are necessarily bad for your health and your waistline. Cassava is extremely high in carbohydrates but it is also high in fiber and a number of healthy minerals and vitamins. Far from being bad for your health, cassava can actually benefit you in a number of ways. If you are interested to find out more about this root, read on.
What is Cassava?
Cassava is a starch laden root vegetable mainly cultivated in hot, tropical climates including parts of Africa, South America and Asia. Also known as yuca, yucca, tapioca or manioc, it was once considered a poor man’s food but its reputation is now beginning to change for the better.
Cassava may not yet be a staple in western kitchens but it offers numerous nutritional benefits that maybe we should be taking advantage of.
Cassava is very high in calories. It contains about twice as many calories as the potato. It is also very high in protein and contains many very important minerals.
As a word of warning, cassava is toxic to humans when eaten raw as it contains cyanogenic glycosides. However, the cooking process reduces these dangerous chemicals to harmless levels.
There are actually two types of cassava – sweet cassava and bitter cassava. The bitter version contains more toxins meaning they have to be thoroughly washed and crushed before being eaten.
The sweet cassava is lower in cyanide and can be prepared in the same way you would prepare any other root vegetable.
Cassava roots are similar in appearance to yams but they are larger and can weigh a kilo or more. They have a tough, brown skin surrounding a starchy ‘meat’. Unfortunately, the shelf life of fresh cassava is short and they rot within a few days of being harvested.
Because of this, it is easier to find cassava flour than the fresh root itself. If you can find the fresh root, you should store them in a cool and dry place for a few days at most before cooking them.
Cassava leaves are also edible and are extremely high in protein as well as vitamin K and calcium. They must also be cooked before being eaten.
Cassava is an excellent source of essential minerals including calcium, manganese, iron, phosphorus and potassium. These are all important minerals for growth and development as well as contributing to proper bodily function.
A 100 gram serving contains 16mgs of calcium, 21mgs of of magnesium, 271mgs of potassium and 27mgs of phosphorus.
High in Fiber
Fiber is good for you and the chances are you don’t get enough of it. Cassava is an excellent source of dietary fibers. Fiber is linked to good digestive function, heart health and may play an important role in weight loss.
It can also slow down the rate at which sugar gets absorbed by the bloodstream. This makes cassava a suitable choice for diabetics.
High in Carbohydrates
While not everybody wants to increase their carbohydrate intake, high carb diets are useful for some people especially athletes or people involved in very high energy activities. The carbohydrates from cassava get converted into glucose in the body before being converted into glycogen and stored by the muscles.
High in Saponins
Saponins are a type of phytochemical known to help reduce cholesterol levels. They work by binding to cholesterol and bile acid which prevents their absorption via the small intestine.
Saponins also have antioxidant properties which can help prevent oxidative damage and reduce the risk of disease including serious illnesses like heart disease or cancer.
Because cassava is completely free of gluten, cassava flour is a potential substitute for normal flour. It is especially useful for people with gluten intolerance like those with celiac disease.

Cassava Health Benefits
1. Digestive Health
Cassava is a digestive resistant starch which means it quite literally resists digestion. Resistant starches are considered to be the most beneficial type of starch because they feed the good bacteria in the gut.
Most starches break down and get absorbed as glucose but resistant starches like cassava travel unimpeded through the intestines to the colon. They are then converted into beneficial fatty acids by the intestinal bacteria where they help combat inflammation and boost your energy.
These short-chain fatty acids like butyrate are known to help treat several conditions including IBS and colitis.
The fiber content of cassava also contributes to a healthy digestive system and can help combat constipation, bloating and indigestion.
2. For Heart Health

One study published in 2013 found that both cassava and sweet potatoes helped to lower cholesterol in people with elevated levels.

The saponins found in cassava also help reduce cholesterol by binding to unhealthy cholesterol and preventing its absorption into the small intestines.
As well as reducing your cholesterol levels which has very beneficial effects on the heart and overall health, cassava is a good source of potassium. Potassium is known to help regulate the heart beat and keep blood pressure under control.
