Soylent hits back at claims of unsafe levels of lead and cadmium

The meal-replacement startup argues that the metals are only present in safe levels

Food replacement startup Soylent has hit back at claims that its product contains unhealthy levels of lead and cadmium, after environmental campaign group As You Sow announced its intention to sue the firm under California's Proposition 65.

The law, also known as the Safe Drinking Water and Toxic Enforcement Act of 1986, imposes strict limits on the levels of toxic elements that can be found in foodstuffs without a warning label. But Soylent argues that its only error is one of labelling, and that the levels of the metals in its product are totally safe.
