Sally K. Norton, a Richmond nutrition researcher and consultant, will conduct a two-part seminar from 6:30 to 8:30 p.m., November 3 and 10, at Goochland County Parks and Recreation. She will share the simple diet changes that can relieve or completely eliminate many painful, long-standing health problems.

Those with joint pain, chronic fatigue, gout, bone loss or sleep, kidney or stomach disorders may not know that a chemical naturally occurring in foods we believe are healthy could be to blame. “People don’t know that foods such as spinach, soy, celery, figs and almonds can be a problem,” says Norton.

Those foods contain the highly corrosive chemical, oxalic acid. Oxalic acid bonds with calcium, iron, magnesium and other metals to form tiny crystals called oxalates that irritate bladders and lodge in arteries, joints, bones and kidneys.
