Mutton flaps are parts of sheep that are often used for meat, just like chicken or beef. However, there is some controversy surrounding them because they are very high in fat and are considered a less healthy option than other cuts of meat.
Think of it like this: when you eat junk food like candy or chips instead of fruits and vegetables, you're not getting as many nutrients and it's not as good for your body. Mutton flaps are similar to junk food for sheep - they don't offer as much nutrition and can be bad for their bodies if they eat too much of it.
Because of this, some people think that mutton flaps should not be sold or eaten because they are not a healthy option. However, others argue that they are a cheap source of protein and should be available for people who cannot afford more expensive cuts of meat.
Overall, mutton flaps are a part of sheep meat that some people like to eat, but there is some debate over whether they are a healthy choice.
