Silicon balance in human volunteers; a pilot study to establish the variance in silicon excretion versus intake

Nutrition & Metabolism

Table 2 Estimated silicon content ¹ of the meals (mg Si/meal) provided to all participants during the study period

Meals	Components	Day 0³(mg Si)	Day 1 (mg Si)	Day 2 (mg Si)
Breakfast	Egg fried rice with pork/chicken, orange juice, drinking water²	6.78	7.70	7.34
Lunch	Rice with chicken, drinking water², yogurt, sponge cake	7.59	7.33	9.01
Dinner	Rice with stir-fried pork/chicken with kale, melon, drinking water²	9.93	7.43	7.97
	Total Si intake per day	24.29	23.86	23.91

¹Calculated from reference food Si values (5, 18).
²Produced from tap water by reverse osmosis (Si concentration = 0.67 mg Si/L as analysed here by ICP-OES).
³Day 0 = pre-dose, baseline collection period, conducted 24 h prior to ingestion of the test solutions on day 1.
