Trans Fat: Heart Attack Risk and Prevention
Trans fat is a type of unhealthy fat found in some processed foods.
It can harm your heart by increasing bad cholesterol and decreasing good cholesterol, which can lead to heart attacks.
Trans fats are often found in fried foods, baked goods, and snacks.
The World Health Organization says we should limit our intake of trans fats to stay healthy.
People with conditions like diabetes or high blood pressure are at higher risk.
To avoid trans fats, read food labels, choose healthier fats like olive oil, and eat more home-cooked meals.
Trans fats increase LDL (bad) cholesterol and decrease HDL (good) cholesterol, leading to heart disease.
Common sources include vanaspati, deep-fried foods, commercial bakery products, and packaged snacks.
The WHO recommends limiting trans fat intake to less than 1% of total daily energy intake.
High-risk groups include people with diabetes, obesity, high blood pressure, and existing heart disease.
Healthier alternatives include olive oil, nuts, seeds, fatty fish, and avocados.

Health Risks of Trans Fats
Regulatory and Consumer Actions
Health Impact
Health Risks of Trans Fats
Trans fats significantly increase the risk of heart disease by raising LDL cholesterol and lowering HDL cholesterol, leading to plaque buildup and potential heart attacks.
Regulatory and Consumer Actions
Regulations and consumer awareness have led to a reduction in the use of industrial trans fats, but they still remain in some processed foods.
