Calories Fat Cholesterol and Sodium

One tablespoon of mustard seed contains about 53 calories, with 3.2 grams of total fat. The mustard seed contains only 0.2 grams of saturated fat, which is about 0.8 percent of your recommended daily saturated fat intake; no cholesterol; and a measly 0.6 milligrams of sodium.
