Studies have proven that there is an inverse relationship between regular consumption of green tea and body fat percentage and distributions.

However, compared to coffee, the tea includes a lower level of caffeine, which might cause sleeplessness but can also improve cognitive capacities. Green tea drinking can cause uneasiness, sleep difficulties, vomiting, and headaches in caffeine-sensitive people.

Because the tea plant absorbs Aluminum (‘Al’), ‘Al’ tends to accumulate in the body with increased tea consumption. If one has serious kidney problems and needs to limit your dietary ‘Al’ consumption, it’s best to avoid drinking green tea or any other type of tea daily. Green tea contains less Al than black tea. Tea catechins also can chelate iron (Fe), lowering the availability of ‘Fe’ when ingested close to a meal.
