Magnesium

According to the Office of Dietary Supplements (ODS), seeds are good sources of magnesium, one of the seven essential macrominerals.
In one study, scientists found that 100 grams (g) of pumpkin seeds contained 90.69 milligrams (mg) of magnesium.
The ODS recommend that males aged 19 to 30 years should consume 400 mg of magnesium a day, and females 310 mg or 350 mg during pregnancy. Older people should have a slightly higher intake.
Magnesium plays an important role in over 300 enzymatic reactions within the body, including the metabolism of food and synthesis of fatty acids and proteins. Magnesium is vital for the proper functioning of muscles.
Magnesium deficiency is prevalent in older populations. It is linked to insulin resistance, metabolic syndrome, coronary heart disease, and osteoporosis.
