Nuts contain the good fats the body needs to keep healthy. Research has shown that a diet of nuts won't make you gain weight.
Best bit is they go so good with beer.
But go with the unsalted nuts, much better for you. The other good thing for your gut ( internally speaking) is psyllium husks, a sprinkling on your cereal or in a glass of cold water or fruit juice. Don't sprinkle it on warm anything is quickly turns to gloop.
