Due to its flavonoid content and antioxidant potential, the Jonagold apple can neutralize aggressive substances and can thus protect against cancer and heart attacks.
Red Delicious apple The Red Delicious apple has become known for its high procyanidin content of around 207.7 milligrams per apple and is very healthy. Procyanidin prevents the buildup of platelets, which constrict blood vessels and disrupt blood flow. Thus, the Red Delicious apple can act like a vessel cleaner.
Granny Smith apple The Granny Smith apple has many valuable and healthy substances and it has enormous amounts of them, such as potassium, vitamin C and magnesium. 100 grams of a Granny Smith apple has the same effect as 400 milligrams of pure vitamin C.
Gala apple The Gala apple is small, tastes sweet, is healthy and can protect against flu thanks to its flavonoids. Flavonoids protect body cells from damage that increases the risk of cancer and reduce the growth of viruses and bacteria.
