Substituting regular meat with crocodile meat could have various health benefits:

Lean Protein
Crocodile meat has a low carbohydrate content, high protein content, low saturated fat content, high iron content, and fewer calories than other meats, therefor reduce the risk of obesity and diabetes.

Low Cholesterol
Crocodile has far less cholesterol than other meats. A 300-gram serving only contains 23 mg of cholesterol, which is below our daily recommend allowance of 300 mg.

Omega 3s
Crocodile meat is rich in omega 3 fatty acids, which many other meats do not contain in great quantity. Omega-3 normalizes and regulates your cholesterol triglyceride levels by reducing the enzyme activity that causes the liver to metabolise fat. Studies have also shown that omega-3 fats are anti-arrhythmic (preventing or counteracting cardiac arrhythmia), anti-thrombotic (prevents thrombosis or a blood clot within a blood vessel), anti-atherosclerotic (preventing fatty deposits and fibrosis of the inner layer of your arteries), and anti-inflammatory (counteracting inflammation – the heat, pain, swelling, etc.).  Omega-3 also has a great impact on your brain health by its influence on brain dopamine levels, neural regeneration and cerebral circulation.

Anti-Carcinogenic and arthritic
Crocodile meat is believed to have anti-carcinogenic properties.
