What Foods Increase Platelet Count?

The Platelet Disorder Support Association notes that leafy greens such as kale, collard greens and seaweed increase platelet count, according to Kim Zupnik for Nutrition Warriors. These foods contain calcium, minerals and vitamin K, which are nutrients beneficial to platelet health.

Individuals wishing to increase platelet count should eat a wide variety of fresh, whole foods, says Zupnik. These foods include whole-grain cereals, brown rice and whole-wheat products, rather than white flour and highly processed grains. Eat organic foods that have not been treated with chemical fertilizers or insecticide and consume healthy fats in the form of cold-pressed canola and olive oils. Drink plenty of pure, filtered or bottled water at room temperature or above for increased platelet count.

Foods to avoid when trying to increase platelet counts include sugar, dairy, alcohol and excess meat, reports Zupnik. Protein sources recommended by the Platelet Disorder Support Association include lean, white fish; whole grains; beans; and nuts. Many foods thought of as healthy should be avoided by individuals working to increase platelets. These include blueberries, dark grapes, garlic, onions, ginger, ginseng and tomatoes; they can interfere with blood clotting. Quinine, a substance found in tonic water, should be avoided as well because it can lower platelet counts.
