There are very limited data concerning the influence of low-level trans fatty acid (TFA) intake on blood lipid levels. In this study, correlation of total and diene TFA intake with serum cholesterol levels was studied in young Japanese women. The mean intakes of total and diene TFAs were 0.36% and 0.05% of energy, respectively. There was a significant correlation between total fat intake and TFA intake. TFA intake was significantly correlated with erythrocyte TFA content. Total TFA intake was not correlated with total, LDL- or HDL-cholesterol levels. No correlatuon was found between diene TFA intake and cholesterol level. Total and diene TFA intake were not correlated with hemoglobin A1c or C-reactive protein levels. These results suggest that the average TFA intake of young Japanese women does not adversely affect serum cholesterol levels.

Purpose: Canada's public health objective is that ≥ 90% of the population consume <1% of total energy (< 1%En) as trans fatty acids (TFA), in line with World Health Organization recommendations. Our study aimed to estimate usual intakes of total TFA, industrially-produced TFA (i-TFA), and naturally occurring TFA (n-TFA) overall and in subgroups of the population before Canada's 2018 prohibition on the use of partially hydrogenated oils (PHO) in foods.
Methods: Data from 1-2 24-h recalls was available for 19,670 participants in the cross-sectional Canadian Community Health Survey (CCHS)-Nutrition 2015.

The intake of trans-fatty acids (TFA) is strongly associated with an increased risk of cardiovascular diseases and elevated low-density lipoprotein cholesterol levels in blood. This review explores the critical factors influencing TFA formation during industrial vegetable oil processing and home cooking practices, particularly deep-frying. While hydrogenation, a major source of TFA, has been largely eliminated in developed countries, it remains unregulated in many developing countries, posing significant health risks.

: Infertility poses a considerable threat to female reproductive health on a global scale. Dietary pattern, as a modifiable lifestyle factor, is frequently recommended as an important intervention for infertility-related diseases. Fatty acids play a crucial role in maintaining the health of the female reproductive system.

Article Synopsis
- This study examined how changes in fatty acid intake relate to mortality among 65,179 adults over several years.
- A higher total fat intake (5% increase) was linked to lower overall mortality, while specific types of fats (polyunsaturated and monounsaturated) were associated with even greater reductions in mortality risk.
- Conversely, an increase in trans fatty acid intake raised mortality risk, with certain fats like marine n-3 PUFA significantly lowering deaths from various diseases.
