7 Reasons Why Eating Yams and Cassava is Linked to Having Twins
Yams and cassava, two staple foods in many African diets, have long been associated with an increased likelihood of conceiving twins. This fascinating connection has sparked both scientific and cultural interest.
The connection between yams, cassava, and twin births is a fascinating blend of science and tradition. While more research is needed to fully understand the mechanisms behind this link, the high levels of phytoestrogens, diosgenin, and other nutrients in these root vegetables are likely contributors.
Additionally, the cultural and genetic factors in regions where yams and cassava are dietary staples further support the belief that these foods play a role in the higher incidence of twin births.
Whether through tradition or nutrition, the consumption of yams and cassava remains a significant and intriguing factor in the world of fertility and twin conception. Here are some reasons why these root vegetables are believed to aid in twin births.
1. High Levels of Phytoestrogens
Yams, particularly the wild varieties found in West Africa, contain high levels of phytoestrogens. These plant-based compounds mimic the hormone oestrogen in the body. Elevated oestrogen levels can lead to the release of more than one egg during ovulation, increasing the chances of conceiving fraternal twins.
2. Diosgenin: A Natural Hormone Booster
Diosgenin, a compound found in yams, is a natural precursor to progesterone, another key hormone in the reproductive process. By boosting progesterone levels, yams may enhance the overall fertility of women, thereby increasing the chances of multiple ovulations in a single cycle.
3. Cassava’s Role in Hyperovulation
Cassava, another root vegetable commonly consumed in Africa, is thought to have a chemical property that inhibits the enzyme responsible for breaking down gonadotropins. Gonadotropins are hormones that stimulate the ovaries to release eggs. By inhibiting this enzyme, cassava can lead to higher levels of gonadotropins, promoting the release of multiple eggs and thus increasing the likelihood of twin pregnancies.

4. Nutrient-Rich Diets
Both yams and cassava are rich in essential nutrients, including vitamins and minerals that support reproductive health. A diet high in these root vegetables ensures that women have the necessary nutrients to support a healthy pregnancy, including the potential for carrying twins.
5. Traditional Beliefs and Practices
In many African cultures, the consumption of yams and cassava is steeped in traditional beliefs and practices. In regions like Igbo-Ora in Nigeria, often referred to as the “Land of Twins,” the local diet heavy in yams is believed to be a major contributing factor to the high twin birth rate. While scientific evidence is still being explored, cultural practices and dietary habits play a significant role in this phenomenon.
6. Genetic Factors
Genetics also play a critical role in the likelihood of having twins. Communities with diets high in yams and cassava often have higher incidences of twin births, which may be partly due to genetic predispositions passed down through generations. These genetic factors, combined with a nutrient-rich diet, create an environment conducive to multiple births.
7. Increased Folic Acid Intake
Yams and cassava are excellent sources of folic acid, a vital nutrient for women trying to conceive. Folic acid is known to support healthy cell division and DNA synthesis, both crucial for a successful pregnancy. Higher folic acid intake is also linked to increased fertility and the possibility of multiple births.
