According to the Platelet Disorder Support Association, a change in diet can help build up blood platelets. An organic diet rich in nutrients can have a beneficial effect on someone's platelet count.
The Platelet Disorder Support Association suggests eating fruits and vegetables and eliminating harmful foods that contain few nutrients, vitamins or minerals. Many low-nutrient foods also add extra fat and promote acid indigestion. Some foods containing quinine, aspartame or alcohol can cause low platelets; elimination of these foods from a person's diet can promote platelet buildup.
Oxidative stress, or inflammation, impairs bone marrow cell functions and inhibits the production of blood platelets; the reduction of oxidative stress can have a positive effect on the number of blood platelets. One type of anti-inflammatory diet is the macrobiotic diet: It encompasses whole grains, beans and vegetables and minimizes the consumption of meat, poultry and dairy.
Calorie restriction can also have a positive effect on blood platelets. In a scientific study of mice with a blood platelet disorder, those who consumed 32 percent fewer calories had an improved platelet count and a longer lifespan. Calorie restriction in humans can promote good nutrition, slow the aging of the cardiovascular system, reduce inflammation and prevent bone marrow fibrosis.
