Milk, tea and fruits do not mix well.


Scientific studies in recent years suggest that antioxidants found in tea and berries such as blueberries and cranberries are the key to slowing the aging process and prevent diseases such as Alzheimer’s, Parkinson’s, cancer and cardiovascular disease. Foods containing these compounds should thus constitute a large part of the daily diet. Following these studies, the consumption of berries has increased dramatically. They are found nature, frozen, dried, juice, compote and also mixed with milk products such as yogurt and ice cream. milk and fruitsAlthough excellent in taste, these amalgams dairy / fruit should be avoided as milk proteins have a negative impact on phenols and polyphenols, the active compounds found in plants and that provide antioxidant benefits.  In a recently published study, the researchers added a preparation of strawberry to yogurt and found an immediate decrease in the total antioxidant activity by 23%. It was the same with blueberry, pomegrenade but also with green tea. In the case of green tea, the decrease is more noted with catechin and epicatechin with a loss of 60% each. These compounds are behind the protective effects of green tea, and are also found in coffee and cocoa. That would explain the reason why the dark chocolate antioxidant content is significantly stronger than the one of milk chocolate. It looks to be the same with black tea that is as powerful as green tea but usually taken with a dash of milk.
