Its Lean Cuisine and Stouffer's meals no longer have preservatives, such as sodium benzoate, and Nestlé just launched the preservative-free Sauté Sensations line of frozen meals. Leslie Chester, president of the frozen meals division for Nestlé Canada, says, "We have a checklist: It has to taste great. It has to have no preservatives. It has to meet the Heart and Stroke Foundation Health Check nutritional requirements for sodium [less than 720 mg per serving]. And it should have a minimum of two servings of vegetables per serving."
