Different Types of Fat

An archived page from the former Health Check nutrition program site. Kept because other sites still link here. Not part of HealthCheck.org's imaging services.

There are four main types of fats that make up the fat in food:

Healthy fats (unsaturates):

  • Monounsaturated fats/Monounsaturates
  • Polyunsaturated fats/Polyunsaturates
    • Omega-3 fat
    • Omega-6 fat

Unhealthy fats:

  • Saturated fats
  • Trans fats

The different fats behave differently in our bodies, and the impact does vary on our risk for certain diseases.
