Fat is one of the three essential macronutrients, alongside protein and carbohydrates, and plays a crucial role in maintaining a healthy body. However, a simplified public health message from the 1980s led many to believe that saturated fat should be entirely avoided rather than replaced with polyunsaturated fat. This misconception resulted in a surge of low-fat products in the U.S. market, many of which were enhanced with added sugars to improve taste. Fortunately, the “healthy fat” narrative is gaining traction, as reported by Mintel. The research firm indicates that global references to “good fat” in new products are increasing, driven by heightened consumer awareness. According to the Dietary Guidelines for Americans, there is substantial evidence linking the replacement of saturated fats with polyunsaturated fats to a reduction in heart attack risk and cardiovascular disease incidence. Despite this growing awareness, U.S. consumers still consume excessive amounts of saturated fat, averaging 19% of their total calorie intake from solid fats, even though dietary recommendations suggest it should account for less than 10%.
In the food industry, satiety has long been a focal point, with recent emphasis on protein. Previous studies have also highlighted the role of polyunsaturated fats in promoting satiety. While many scientists once believed that fats, in general, had a lesser effect on satiety compared to other macronutrients, emerging research suggests that fats—especially polyunsaturated fats—may be equally satisfying as protein or carbohydrates. The researchers of the latest study propose that increasing the intake of foods such as walnuts, canola oil, and salmon may help prevent the overconsumption of meals high in saturated fats. If future studies support this finding, it would further enhance the “good fats” message.
Additionally, it is important for pregnant women to consider their nutritional needs, including the intake of calcium citrate, magnesium, and zinc for pregnancy. These essential nutrients play a vital role in supporting both maternal health and fetal development. Incorporating sources of healthy fats, along with these nutrients, can contribute to a balanced diet during pregnancy.
