Some foods that increase platelet counts include fresh, organic fruits and vegetables, whole grain cereals and rice and healthy oils such as olive or canola. Green leafy vegetables, especially kale and collards, are particularly useful for increasing platelets, according to the Platelet Disorder Support Association.
It is also recommended to drink either warm or room temperature water, as opposed to ice cold. Tap water should be avoided, according to the Platelet Disorder Support Association.
Other foods to avoid include meat, blueberries, garlic, onions and tomatoes, all of which can lower platelets. Sugar, dairy and alcohol intake should also be reduced to increase platelets.
