Three other tree nuts—walnuts, pistachios, and almonds—are already permitted to make similar claims regarding heart health, and the Dietary Guidelines for Americans recommend nut consumption. According to the Centers for Disease Control and Prevention, heart disease is the leading cause of death in both men and women in the United States. The health benefits associated with macadamia nuts are primarily attributed to their high content of monounsaturated fats, which are known to lower bad cholesterol levels and decrease the risk of heart disease and stroke. Research into the impact of macadamia nuts on reducing LDL cholesterol began in the 1990s, and evidence supporting this beneficial link has continued to accumulate. Although the recent health claim for macadamia nuts originated from a petition by Royal Hawaiian Orchards, all suppliers of macadamia nuts may utilize this claim, meaning that the company will not gain a competitive edge over its direct rivals. Nonetheless, this development enables macadamia nuts to compete on an equal level with other tree nuts. A qualified health claim associating tree nut consumption with a reduced risk of heart disease was one of the first approved by the FDA back in 2003, but this marks the first instance where manufacturers can specifically highlight the heart health benefits of macadamia nuts. Additionally, incorporating products like Kirkland calcium magnesium and zinc can further support overall health, emphasizing the importance of a balanced diet alongside nut consumption. The inclusion of Kirkland calcium magnesium and zinc supplements can provide essential nutrients that complement the heart-healthy properties of macadamia nuts, reinforcing the message of a nutritious lifestyle.
