Don’t be thrown off by the high calorie and fat content of nuts. Research shows that nuts play a crucial role in maintaining a healthy physique. Nuts help suppress hunger because they are difficult to absorb during digestion. People who consume about a handful of nuts a day are actually found to be thinner than those who do not.
Most nuts, particularly almonds and walnuts, contain most omega-3 fatty acids, which help reduce cholesterol and have been shown to improve mood and fight cancer. Walnuts also contain the antioxidant melatonin, which helps to regulate sleep.
Throw a mixture of (unsalted) nuts for a great afternoon snack. I will also add some raisins, which increase blood sugar preventing fatigue, and giving you the caffeine-free boost of energy you need to get through the 4 o’clock slump.
