All nuts have some type of health benefit for diabetics, according to SFGate. Almonds have high levels of vitamin E, walnuts have alpha-linolenic acid and cashews are packed with magnesium.
People with type 2 diabetes should replace snacking on carbohydrates with eating about 2 ounces of nuts per day, says WebMD. This can lead to lower bad cholesterol levels and improved blood sugar control. Many nuts may also be beneficial to those at risk for heart disease, notes SFGate. Nuts with higher vitamin E levels, such as almonds and walnuts, slow plaque development that can lead to atherosclerosis, while omega-3 fatty acids, found in walnuts, reduce the risk of irregular heartbeats that can lead to heart attacks.
