Mixing spinach with sukuma wiki (also known as kale) is a common practice in many households, especially in African cuisine, where both leafy greens are staple vegetables......See Full Story>>.....See Full Story>>
However, recent findings have raised concerns about the potential health effects of combining these two vegetables. Although both spinach and sukuma wiki are rich in vitamins, minerals, and fiber, combining them might not be as beneficial as once thought due to specific compounds they contain.
One of the main concerns revolves around the high levels of oxalates found in spinach. Oxalates are naturally occurring substances in certain foods that, when consumed in large quantities, can bind with calcium and form insoluble crystals. These crystals may contribute to kidney stone formation in susceptible individuals, particularly when consumed in excess.
While oxalates are present in various foods, spinach is particularly rich in them. When spinach is consumed alongside sukuma wiki, which also contains oxalates but in slightly lower amounts, the combined intake may increase the total oxalate load on the body, raising the risk of kidney stones and other related issues, especially if the person has a history of kidney problems.
Moreover, both spinach and sukuma wiki contain goitrogens, compounds that can interfere with thyroid function by inhibiting the absorption of iodine. While the effects of goitrogens are usually mild and can be mitigated through cooking (which deactivates many of these compounds), consuming large quantities of both vegetables together could exacerbate the risk, particularly for individuals with pre-existing thyroid conditions. It is important to note that this effect is more significant when raw vegetables are consumed, as cooking can reduce the goitrogenic effect.
Another factor to consider is the balance of nutrients. While both spinach and sukuma wiki are packed with essential vitamins like A, C, and K, as well as minerals like iron and calcium, they also have different nutrient profiles. For example, spinach has higher levels of folate, while sukuma wiki is richer in calcium. Mixing them in large amounts might lead to an imbalance in nutrient absorption, especially in individuals with specific dietary needs.
In conclusion, while spinach and sukuma wiki are both highly nutritious, consuming them together in large quantities may pose some health risks, particularly related to oxalates, goitrogens, and nutrient imbalances. It is advisable to eat them in moderation and, where possible, vary one’s vegetable intake to ensure a more balanced nutrient profile. For individuals with kidney or thyroid concerns, it may be best to consult with a healthcare provider or nutritionist before combining these greens regularly in meals.
