But watch out for this terms---hydrogenated vegetable fats or oils and transfat.
Just because we see the word "vegetable" we think it's healthy. Hydrogenated vegetable fat is really dangerous for the heart. So if you are fond of eating biscuits to appease hunger and you do this regularly, I hope you don't end up with a heart problem someday.
Hydrogenation puts hydrogen atoms in oil, the process reduces the amount of unsaturated fatty acids and increases saturated fatty acids in the oil. When you take in lots of saturated fatty acids, you increase your cholesterol levels which may lead to serious heart problems.
Healthy eating means you lower your saturated fats intake. But you do the opposite when you always eat quick snacks like cup cakes, biscuits and cookies with tansfats or hydrogenated vegetable fats. These fats are also present in most sandwich spreads. So, white bread (which is bad for your health) plus sandwich spread with hydrogenated vegetable oils equals serious health problems.
I often snack on fresh fruits. When there are no fruits around, I eat traditionally cooked hopia with no preservatives.
Well, sometimes you have no other option but to eat snacks with hydrogenated stuff. When you're out of the house and find yourself in modern eateries, you are likely to eat these things.
So make sure to always counter them with fresh fruits high in antioxidants. Or drink natural and fresh carrot juice.
