Animal Proteins

Advantages:

• Enough of all the essential amino acids
• Slightly higher digestibility
• Higher proportion of protein to the received volume

Disadvantages:

• Higher in saturated fat
• The risk of putrefactive products and provocation of a colon cancer
• Greater burden on the liver and kidneys
• Residual content of antibiotics, growth stimulants, drugs or chemicals
• The risk of food allergies (milk protein)

Vegetable Proteins

Advantages:

• Lower amounts of some toxic substances
• Minimum amounts of cholesterol
• High content of essential fatty acids
• High content of healthy substances – vitamins, minerals, fiber, enzymes

Disadvantages:

• Incompleteness of amino acids
• Small absolute amount of proteins – therefore the need of a greater volume of food
• Higher risk of heavy metals occurence
• The risk of food allergies – soy, wheat
