Saturated fat, also known as trans-fat or partially hydrogenated oil can cause a host of health related problems, such as clogging of the arteries, type-2 Diabetes in children and adults, obesity.
It is better to eliminate saturated fat rather than limit, if possible.
As a teenager you do not need to limit your intake of saturated fat. I would recommend at least 10% of your calories come from saturated fat.

The recommended intake of saturated fat that an adult human should consume is up to 5 grams. Saturated fat can cause weight gain, increase in cholosteral, and raise your blood pressure.
The amount of recommended saturated fat intake depends on a person's calorie diet. If he consumes 2,000 calories a day, he should consume not more than 200 calories of saturated fat.
According to the American Heart Association and also the USDA's 2005 Dietary Guidelines for Americans, you should limit dietary cholesterol to 300 mg per day regardless of caloric intake. However, if you are watching cholesterol, you also need to limit saturated fat to less than 10 percent of your total calories. Both saturated fat and trans fat increase cholesterol levels. So, in your case that would mean you should limit saturated fat to 380 calories or about 40 grams.
No RDI is stated for unsaturated fat however there is for saturated fat. (approx 20 - 25 grams saturated fat for an recommended total intake of about 70 grams of fat.) So this works out to be a ratio of about 30% saturated and 70% unsaturated. Meaning, if your total fat intake is around 70g then this would amount to 20g for saturated and 50g for unsaturated fat.
It is about 20 to 25 grams of saturated fat out of a recommended total intake of about 70 grams of fat (about 30% saturated and 70% unsaturated).
Intake of saturated fat raises blood cholesterol more than intake of cholesterol
Too much saturated fat can raise blood cholesterol, which can increase the risk of heart disease. You should therefore consume no more than your recommended daily intake.
The daily recommended intake for fat is 18 grams or less for a total of 1,600 calories. You should take about 25 percent fat of your daily calories.
Most vegetable spring rolls contain 3.5 to 4 g of total fat and 0.5 to 1.0 g of saturated fat. High intakes of fat and saturated fat can increase your risk of high cholesterol and heart disease.
