The video tutorial explains the different types of fats, including omega-3 fatty acids, saturated fats, unsaturated fats, and trans fats. It discusses their molecular structures and how they affect health, particularly in terms of cholesterol levels and risks of heart disease. The tutorial emphasizes that unsaturated fats are generally healthier than saturated and trans fats. It concludes with a positive message about kindness.

Which type of fat is known to support brain function and has anti-inflammatory properties?

• Trans fats
