If fish are eaten as part of the weekly diet, research reveals that the smallest fish are the safest. And we have seen that garlic helps lower mercury levels. It is good to know that various fruits have also been linked to reduced mercury in the body from dietary contamination:
“Eating tropical fruit reduces mercury exposure from fish consumption in the Brazilian Amazon…A 12-month prospective dietary survey was carried out with 26 adult women from a fish-eating community in the Brazilian Amazon. Food ingestion was determined using a daily food diary, and total hair Hg [mercury] levels were assessed for each month…for the same number of fish meals, those who ate more tropical fruits had lower hair mercury levels…Many types of fruit are seasonally available, but the most commonly eaten are bananas (Musa spp., Musaceae), ingas (Inga spp., Leguminosae-Mimosoideae), and Oranges (Citrus spp., Rutaceae). A negative correlation was observed between the frequency of fruit consumption (all fruit) and HHg… As expected, the consumption of carnivorous fish, which are higher in the trophic chain and have higher levels of Hg, correlates positively with HHg (Dolbec et al., 2001; Lebel et al., 1997)… A number of phytochemicals and nutritional fibers present in fruits might be interacting with Hg [mercury] in several ways: absorption and excretion, transport, binding to target proteins, metabolism, and sequestration…a number of studies suggest that an important group of health promoting phytochemicals is the polyphenols (Bravo, 1998). These compounds are particularly abundant in fruits, and one of their important properties is that of antioxidants; they can form complexes with reactive metals, thus reducing their absorption…fruit consumption has been shown to be beneficial for well-being; studies have demonstrated that fruits reduce the risk of many chronic diseases (Botterweck et al., 1998; Joshipura et al., 1999). Here, bananas, inga´s, and oranges showed the largest influence on HHg…”

“Methylmercury (MeHg) is a potent neurotoxin that crosses the blood-brain and placental barriers, leading to developmental and neurocognitive impairment (Castoldi et al., 2001; Steuerwald et al., 2000)…After being absorbed in the gastrointestinal tract, MeHg quickly enters the blood stream and is distributed throughout the human body (Clarkson et al., 2007)…Tropical fruit consumption has been associated with an over 60% reduction in Hg levels in human hair and blood (Passos et al., 2007)…”
Although the above fruits are not directly named in the Bible, the virtuous woman of Proverbs did bring her food from "afar." It is reasonable to conclude that the fruits of the Bible will have the same properties (yet likely even more powerful). Oranges, however, are in the rue family, which is named in the Bible (Luke 11:44).
Fruits should be eaten pesticide free.
