Trans Fatty Acids
What are trans fatty acids (TFA)? Fatty acids found in foods can be saturated (SFA, no double bonds), monounsaturated (MUFA, 1 double bond) or polyunsaturated (PUFA , 2 or more double bonds). The double bonds provide rigidity to the molecule and result in specific molecular configurations. Naturally occurring fatty acids in foods usually have the cis configuration, i.e. the hydrogen atoms with ...

متن کاملTrans Fatty Acids, does Exist Safety Dosage?
Recent data regarding Trans Fatty Acids (TFAs) have implicated this lipid as being particularly deleterious to human health. TFAs are unsaturated fatty acids that contain at least one non conjugated double bond in the trans configuration, resulting in a more linear shape. The presence of a trans double bond in a fatty acid chain results in a smaller bond angle, or kink, than in a cis double bon...
متن کاملSignificance of Trans Fatty Acids in Cancer
Trans fatty acids (TFAs) are a recent focus of health problems. TFA is a definitive risk factor for cardiovascular diseases and the death. TF A is also possible risk factor for Alzheimer's disease, obesity, diabetes, fatty liver, and ovulation infertility. The relationship between TF A and carcinogenic risk is controversial; however, TF A is reported to increase the risk of breast cancer and pr...
متن کاملTrans fatty acids and coronary heart disease.
Epidemiologic evidence has linked trans fatty acids (TFAs) in the diet to coronary heart disease in human populations. It has been estimated that dietary TFAs from partially hydrogenated oils may be responsible for between 30,000 and 100,000 premature coronary deaths per year in the United States. Although it is known that TFAs increase low-density lipoprotein (LDL) cholesterol levels and decre...
