2 Grapefruit
Grapefruit contains an active ingredient called quinine. This is thought by some to effectively neutralize the parasites that are responsible for malaria symptoms. At the same time, it is able to strengthen the immune system and support it in doing its job.
Grapefruit has a ton of health benefits besides this. It is actually considered to be one of the few ‘negative calorie foods’ for instance and is a staple in countless diets. If you want to forego the sour taste though, then you can actually extract the quinine yourself. Simply boil the pulp of the grapefruit and it will be released.
On top of everything else, grapefruit is also high in vitamins A and C, which will help to strengthen the immune system to fight the good fight.
