molybdenum: am I low in this?

i had took decay... and mercury poisoining, and i dont eat any of the foods high in it (no legumes, etc)

How do you get enough from foods?
The amount of molybdenum found in foods depends on both the food type and upon the soil in which the food (or fodder) grows. Legumes such as beans, lentils and peas as well cereals and leafy vegetables are considered good sources of molybdenum. Liver is also a good source, but animal products are generally poor sources of the element. In general, the typical America diet contains molybdenum levels well above the Recommended Daily Allowance (RDA).
Are there any risks associated with consuming too much?
Although molybdenum does not have a known toxicity level in humans, taking high concentrations of molybdenum in supplements may have adverse effects on copper levels by interfering with its absorption. One study found that high levels of dietary molybdenum, up to 1,500 mcg, caused excessive excretion of copper. However, another study showed no negative effect of excess molybdenum intake (up to 1,500 mcg per day) on copper levels in humans.
Are there any other special considerations?

  • Molybdenum is abundant in human tooth enamel and may have a role in lowering the risk of tooth decay.

Longevity
Rugao is a county in Jiangsu province (China) renowned for the longevity of its residents. Extended longevity can hardly be attributed to significant differences in traditions, lifestyles, or dietary habits among the residents, and most longevous people are not related to one another, limiting the possible influence of genetics. However, the county has a large number of different soils whose compositions could affect the distribution of trace elements in water and crops and ultimately be linked with human health and longevity. Significant correlations were found between the ratio of people over 90 years old per 100,000 inhabitants and trace elements, including molybdenum, in soils, drinking water, and rice, which constitute key elements of their natural environment (40). The percentage of long-lived people (>80 years old) in Zhongxiang (Hubei province) was also positively linked to the content of molybdenum in their staple food, rice (41). In these regions, it is likely that combinations of trace elements contribute to optimum health and longevity as opposed to the sole effect of molybdenum.
