1. Pork belly

Just imagine some grilled pork belly with some BBQ sauce on top. We already sense the smell of it! Delicious! But at the same time, this is one of the unhealthy protein sources that you should avoid.

Is this a pattern, or is all the good food off-limits because it is not the best for our bodies? Nutrition experts would say that there is no food that is truly off-limits, but they would recommend that you limit the consumption of some foods that can become harmful if consumed regularly.

Pork belly is one of those foods, and the ideal portion you can have is just 3 ounces! But keep in mind that even from this small amount, you will still get 242 calories and 7 grams of saturated fat. And this is a lot.

Consuming meals high in saturated fat may increase your chance of developing cardiovascular disease. If you really like pork belly, you can still have a small portion from time to time if you combine it with other nutrient-dense, high-fiber meals such as vegetables and beans.
