Final answer:
Consumption of trans fats can increase LDL and decrease HDL, leading to an imbalance in blood cholesterol levels and an increased risk of heart disease.
Step-by-step explanation:
Consumption of trans fats can increase low-density lipoprotein (LDL) and decrease high-density lipoprotein (HDL). Trans fats are known to elevate LDL levels, which are commonly referred to as 'bad' cholesterol, and reduce HDL levels, which are considered 'good' cholesterol. This can negatively impact total blood cholesterol levels and increase the risk of heart disease.
