The egg is a nutrient-dense food and contains a number of antioxidants. The consumption of eggs has been considered to improve the balance of diets, although its impact on serum cholesterol levels has been a matter of concern in many countries. Here, we conducted a pilot study to investigate whether daily additional consumption of an egg might affect serum lipid profiles and also antioxidant status in healthy subjects. Fourteen male subjects were provided with breakfasts including a boiled egg for 4 wk. At the end of intervention, serum concentrations of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) were unchanged, despite the significant increase in the intake of dietary cholesterol. In contrast, a significant increase in high-density lipoprotein cholesterol (HDL-C) and a reduction of the LDL-C/HDL-C ratio were observed. Interestingly, the malondialdehyde modified-LDL (MDA-LDL)/LDL-C ratio and the oxidizability of LDL were significantly reduced. Serum total antioxidant capacity value after the intervention period was higher than at baseline. These data indicate that consuming one egg per day for 4 wk as breakfast in addition to a normal diet does not affect serum lipids, and suggests that it may improve serum antioxidant status in healthy males.

The food supply system is facing important challenges and its sustainability has to be considered. Genome-editing technology, which accelerates the development of new variety, could be used to achieve sustainable development goals, thereby protecting the environment and ensuring the stable production of food for an increasing global population. The most widely used genome-editing tool, CRISPR/Cas9, is easy to use, affordable, and versatile. Foods produced by genome-editing technologies have been developed worldwide to create novel traits. In the first half of the review, the latest scientific findings on genome-editing technologies are summarized, and the technical challenge in genome sequence analysis are clarified. CRISPR/Cas9 has versatile alternative techniques, such as base editor and prime editor. Genome sequencing technology has developed rapidly in recent years. However, it is still difficult to detect large deletions and structural variations. Long-read sequencing technology would solve this challenge. In the second part, regulatory framework and approach for genome-edited foods is introduced. The four government ministries, including the Ministry of Environment, the Ministry of Agriculture, Forestry and Fisheries, and the Ministry of Health, Labour and Welfare (MHLW), started to discuss how the regulation should be implemented in 2019. The SDN-1 technique is excluded from the current genetically modified organism (GMO) regulation. The Japanese regulatory framework includes pre-submission consultation and submission of notification form. In the last part of this review, transparency of regulatory framework and consumer confidence were described. Since maintaining consumer trust is vital, transparency of regulatory framework is a key to consumers. The information of notification process on approved genome-edited foods is made public immediately. This review will help regulators build regulatory frameworks, and lead to harmonization of the framework between the countries.

Green tea and coffee contain various bioactive compounds (e.g., polyphenols), and their consumption has been proposed to decrease the risk of cardiovascular diseases. Here, we investigated the associations between the consumption of green tea and that of coffee and the prevalence of coronary artery disease (CAD) in Japanese patients. The study group was 612 patients who underwent coronary angiography at Tokyo Medical Center between July 2008 and February 2017. CAD was confirmed in 388 of the patients: one-vessel disease (1-VD, n=166); two-vessel disease (2-VD, n=112); three-vessel disease (3-VD, n=110). Myocardial infarction (MI) was found in 138 patients. After adjustment for well-known atherosclerotic risk factors and other dietary habits, greater green tea consumption was significantly inversely associated with CAD prevalence (p for trend=0.044), and the patients who drank >3 cups/d had a lower prevalence of CAD compared to those who drank <1 cup/d (odds ratio [OR]: 0.54, 95% CI: 0.30-0.98). Greater green tea consumption (>3 cups/d) was also associated with a decreased prevalence of 3-VD (OR: 0.49, 95% CI: 0.24-0.98, p-trend=0.047) and MI (OR: 0.51, 95% CI: 0.27-0.97, p-trend=0.037). In contrast, coffee consumption was not associated with CAD or MI. In subgroup analyses, the inverse association between green tea consumption and CAD or MI was found in the high intake groups of vegetables or fruits but not in the low intake groups of vegetables or fruits. These results suggest a beneficial effect of green tea consumption, especially with a diet rich in vegetables and fruits, against coronary atherosclerosis in Japanese.
