The cashew nuts as commonly known are actually a part of the cashew fruit and is in reality a seed. Cashew trees bear fruit called the cashew apple. The stem of the cashew fruit is the encasing of the cashew nut. The nut is hidden inside a toxic casing which contains cashew balm. Cashews aren’t just easily available but very easy to add to the diet as well. A handful of these every morning or any time of the day can boost your health in many ways. The presence of monounsaturated and polyunsaturated fatty acids in cashews make them very beneficial for the heart. In simple terms, these fatty acids are nothing but the ‘healthy’ fats that are extremely essential for your body. Researchers have found out that just 300 mg of magnesium a day for a month is enough to lower blood pressure and so, a handful of cashews every day can prove very beneficial. To relax your blood vessels and improve blood flow, magnesium plays an important role. The presence of potassium in cashews is also responsible for lowering blood pressure.
