Majority of Fats in Almonds Not Absorbed

In the fitness world, almonds are praised for their presence of monounsaturated fatty acids, dietary fiber, antioxidants, vitamins like riboflavin, and trace minerals such as magnesium. In addition to being healthy, several studies have suggested that regular almond consumption can enhance weight loss. Think of almonds as a natural weight loss pill. For example, in the Nurses’ Health Study, showed that people who frequently eat almonds and other nuts retain healthier body weights and lower rates of obesity over time compared to those who avoid nuts. Other studies show that when dieters eat almonds daily, they are less likely to over-consume carbohydrates and more likely to reach and maintain a healthier body weight.

According to a new study just released, the healthy weight loss of almonds may be due to the fact that a majority of the fats in almonds are not absorbed, in a way, almonds are a natural fat blocker.

Results showed that the bioaccessibility of fat from the almonds chewed by the human volunteers was approximately 8% and 11% for natural almonds and roasted almonds, respectively.

In the new study, researchers wanted to quantify the effects of chewing (mastication) on the bioaccessibility of the fats of almond and examine microstructural characteristics of chewed almonds. In the study, 17 healthy subjects chewed raw natural almonds (NAs) or roasted almonds (RAs) in 4 separate sessions. After chewing thoroughly, subjects spit out the food bolus so that researchers could measure the particle size using mechanical sieving and laser diffraction. The researchers used mechanical sieving and laser diffraction to determine the almond piece size and lipid content. The bioaccessibility of the fat was predicted by using a theoretical model, based on almond particle size and cell dimensions, and then compared with empirically derived data. Results showed that the bioaccessibility of fat from the almonds chewed by the human volunteers was approximately 8% and 11% for natural almonds and roasted almonds, respectively. Microstructural examination of the almonds by microscopy indicated that most of the fat remained undisturbed in intact cells of almonds after chewing. These results indicate that almonds have a much lower calorie content than previously thought due to 90% of the fat in almond not being absorbed. Thus, most of the lipid in chewed almonds are not immediately bioaccessible and remains unavailable for early stages of digestion. The low bioavailability of fat in the almonds make it the perfect diet food.
