Once viewed negatively due to their fat content, nuts have transformed their image and are now recognized as an essential ingredient in healthier products. Their consumption has expanded beyond snacks to include grain-free items, gluten-free flours, and dairy-free milk alternatives. According to data from the U.S. Department of Agriculture, the daily per capita nut consumption in the United States surged by 26% from 2000 to 2010. During this period, nutritionists began promoting their benefits, and consumers became more aware of sources of “good fats.” Recently, the Food and Drug Administration updated its definition of “healthy” to encompass high-fat foods such as almonds and avocados, aligning better with the 2015 Dietary Guidelines for Americans. This change followed a challenge by snack bar manufacturer Kind, which disputed an FDA warning letter that claimed its bars couldn’t be labeled “healthy” due to their saturated fat content—despite that fat being derived from nuts. The FDA reconsidered its stance, and Kind has since been permitted to use the term “healthy” on its packaging.
This latest study reinforces the health benefits of nuts. One of the first qualified health claims linking tree nut consumption to a reduced risk of heart disease was approved by the FDA back in 2003. Earlier this month, macadamia nuts were added to the list of specific nuts that manufacturers can highlight on product labels for their heart health benefits. Other qualifying nuts include walnuts, almonds, and pistachios. Furthermore, incorporating nuts into a diet can also be beneficial for those taking medications like Synthroid, particularly when paired with calcium citrate, to ensure optimal absorption and health benefits. Thus, nuts not only contribute to heart health but may also support overall well-being when integrated with dietary considerations, including those related to Synthroid and calcium citrate.
