Proteins have been a long time though to be from specific foods and with adequate research there are some other sources of proteins the make great substitutes to the traditional sources such as meat and milk. Many vegetarians are now able to select from this substitutes to complete their meal experience.

Walnuts are one of the best protein substitutes as they contain not only large amounts of omega-3 fatty acids but also are rich in fiber, vitamins b, magnesium and plant sterols. Salmon is also another good source of proteins and omega-3 fatty acids. Canola is another new generation protein substitute, it easily dissolves in water and its isolates do not affect its color or settle to the bottom as other proteins. It has been rendered safe for human consumption as it contains 1% of erucic acid and people are advised to take twice as much canola oil for every single meal taken.
