In brief English walnut has:
thiamin (0.34 mg | 28% DV)
vitamin B6 (0.54 mg | 32% DV)
folate (98.00 mcg | 25% DV)
magnesium (158.00 mg | 38% DV)
phosphorus (346.00 mg | 28% DV)
zinc (3.09 mg | 28% DV)
copper (1.59 mg | 177% DV)
manganese (3.41 mg | 148% DV)
English walnuts (Juglans regia) are native to Eurasia. The fruits of English walnuts are more commonly eaten than black walnuts. English walnuts have thinner shells, a milder flavor, and are cheaper than black walnuts. Black walnuts have more magnesium and phosphorus than English walnuts.
English walnuts are an excellent source of B-vitamins, such as thiamin (vitamin B1), folate (vitamin B9), and vitamin B6. Thiamin (28% daily value [DV]) and folate (25% DV) contents in English walnuts are much higher than in black walnuts. Thiamin is essential for glucose metabolism, and it plays a key role in nerve, muscle, and heart function. Folate is a necessary nutrient that prevents neural tube defects. Vitamin B6 (32% DV) is important for the immune system, and it may also reduce the risk of cardiovascular disease and support the nervous system.
Magnesium (38% DV) promotes calcium absorption, helps the body build new bone cells, and regulates nerve and muscle activities. Phosphorus (28% DV) strengthens muscles, regulates heart rate, and supports nerve conductivity. Zinc (28% DV) is an essential element required by the immune system. Copper (177% DV) promotes heart health and important for bone and nerve health. Manganese (148% DV) affects cellular respiration, bone growth, glucose metabolism, and brain activity. English walnuts are commonly eaten as a snack or used in baking and salads.
