(15-02-15) The best natural sources of manganese

by Michael Ravensthorpe 

(NaturalNews) Manganese is a trace mineral that is present in only small amounts in our bodies. It is considered an essential nutrient and is responsible for a large number of biological roles, including proper enzyme functioning, wound healing, nutrient absorption and bone development. Manganese is also a component of the antioxidant enzyme superoxide dismutase (SOD), which helps fight cell-damaging free radicals.

According to the University of Maryland Medical Center, up to 37 percent of the American population fails to meet the recommended daily intake (RDI) of manganese, which is 2.3 milligrams for adult men and 1.8 milligrams for adult women. Over time, this can lead to deficiency symptoms such as joint pain, poor bone health and fertility problems. Therefore, it's important that we eat enough foods rich in manganese to maintain our health.
Excellent sources of manganese
Seafood -- Though seafood is best-known for its rich concentrations of zinc, it is also one of the world's finest sources of manganese. In first place is mussels, which provide us with 5.8 milligrams of manganese, or 340 percent of our RDI, per 85 grams. Next on the list is clams (43 percent of our RDI per 85 grams), followed by crawfish (22 percent of our RDI per 85 grams). Regular fish such as bass, trout, pike and perch are also excellent sources of manganese, with 85 grams of each providing us with between 38 and 48 grams of our RDI. Avoid contaminated seafood by favoring sustainably farmed produce sourced from the Atlantic Ocean.

Nuts -- Nuts are one of the best sources of manganese for vegetarians and vegans. One 28 gram serving of hazelnuts, for instance, supplies us with 78 percent of our RDI. Pecans, macadamia nuts and walnuts also contain over 40 percent of our RDI per 28 grams. Other nuts, such as almonds, cashews and pistachios, contain fewer (but still high) concentrations of manganese.

Aside from their manganese content, nuts are also a good source of omega-3 fatty acids, vitamin E, plant sterols (which are known to reduce LDL cholesterol) and L-arginine, a semi-essential amino acid that can boost cardiovascular function. Some people like to soak their nuts in water before eating them, since soaking mimics the natural germination process that occurs in nature, which helps neutralize anti-nutrients and activate certain enzymes.
