limits recommended for health

recommended
• Take care to check the label of foods as even canned vegetables have salt
added. You can check the content at this site:

9 are referred to as essential amino acids as the body is unable to make
them and must get them from the diet
• Animal proteins such as meat, fish, poultry, eggs
and dairy foods contain all 9 and are complete

option however, you need to be aware that products such as cheese often
used in lacto vegetarian meals may have non-Halal (Haraam) ingredients.
