According to Charles Harper, Chairman of ConAgra, the Healthy Choice line of frozen dinners began with his own heart attack. It has been brought on by years of eating anything he could get his hands on. As he lay in the hospital recovering, Harper imagined the line of healthy frozen foods that tasted good. The Healthy Choice product line was carefully tested with consumers before being introduced to the general public. ConAgra’s research and development staff spent a year working under the instruction "Whatever the cost, don’t sacrifice taste". The first test market results surprised even the ConAgra team. The low-sodium, low-fat frozen dinners sold much better than expected. According to the firm’s vice-president of marketing and sales, "We benefited from low expectations. The products were much better than people thought they would be." This finding supported ConAgra’s decision to position the product against other high-quality frozen dinners rather than as a diet or health food. The new product’s brand name and packaging were an important part of the development process. The name Healthy Choice was chosen for the positive implication it held for consumers. Because ConAgra felt the product would be an impulse purchase, it was important to make the item stand out in the freezer case. This was accomplished through the dark green packaging that not only differed from the competitors but also suggested freshness and richness in vitamins.
