Caffeine has a mild diuretic effect, leading to increased urination. As a result, water-soluble vitamins, such as vitamin B complex and vitamin C, may be depleted due to fluid loss.
Studies also show that the higher the level of caffeine, the more it interferes with the absorption of vitamin D. Caffeine can also interfere with calcium absorption.
It has been shown that just one cup of coffee can slightly reduce the body's absorption of calcium and increase its loss due to the diuretic effect of coffee.
Further research concludes that drinking a cup of coffee or tea with a burger reduces iron absorption by 39% and 64%, respectively.
What is the solution?
Excluding all caffeinated beverages can be extremely difficult for some people. Studies show that drinking coffee one hour before a meal has no negative effect on the body's absorption of iron.
It has also been found that increasing the amount of vitamin C and honey in your meals improves the absorption of iron and reduces the bad effects that coffee and other caffeinated beverages have.
However, the healthiest solution is to replace highly concentrated caffeinated beverages with natural foods that are high in nutrients.
Act wisely to minimize coffee consumption for the sake of your health.
