Baby Foods (BFs) and Infant formulas (IFs) are the main sources of nutrition for an infant throughout the 1st year of life. A variety of enriched products are commercially available for parents seeking to fulfill the nutritional needs of infants. Consequently, different bioactive lipids are present in BFs and IFs including dietary oxidative substances (DOxS) whose known toxicity has been associated with mutagenicity, cancer, and other chronic diseases. In this work, we performed an exposure assessment of 25 bioactive lipids on a total of 63 baby food samples (50 IFs and 13 BFs) commercially available in the US. To determine the dietary exposure to DOxS, we used EPA's SHEDS-HT probabilistic model. Even though β-sitosterol was the most exposed bioactive lipid with 75,4 μg/day, cholesterol was the most absorbed compound during the entire first year (19,320 μg/day). Additionally, we found 7α-hydroxycholesterol (7α-OH) as a potential DOxS biomarker of the BFs manufacturing process. This is the first time that an exposure assessment including DOxS ingested by infants after BFs and IFs consumption is performed, enabling much-needed information regarding these hazardous compounds and their potential effects on infants' health.

Ultra-processed foods (UPFs) and their nutritional value have become a trending topic in the scientific community because of their increasing demand, and their potentially adverse effects on human health. Besides the poor nutritional value attributed to UPFs, countless studies have also reported the presence of different dietary oxidized substances in these meals. DOxS are associated with several chronic diseases such as cardiometabolic diseases (CMD), cancer, diabetes, Parkinson's, and Alzheimer's disease. In this study, a database of DOxS and other dietary metabolites detected in 63 UPFs meals part of the Western diet is reported. Significant differences were found in DOxS and phytosterol contents between ready-to-eat and fast food (FF). Putative biomarkers were suggested for RTE (brassicasterol) and FF (7a-OH and 7b-OH), as well as for all 6 different food categories: dairy (brassicasterol), eggs & derivatives (stigmasterol and b-sitosterol), meat & poultry (7a-OH), seafood, baby food (b-sitosterol), and others (campesterol). Ideally, the use of dietary biomarkers could potentially help in the future to identify in an early stage the presence of different chronic diseases, and even, prevent their development. Nevertheless, an exposure assessment is critical to understand the exposure level of DOxS and their relationship with different chronic diseases.

Background: The long-term consumption of junk food products can lead to nutritional and metabolic imbalances, especially when it is associated with a lack of physical activity and the consumption of alcohol or other high-calorie products. Methods: The evaluation of junk food consumption among teenagers and young people in Romania was carried out with the help of a cross-sectional study based on a questionnaire. Results: A total number of 1017 respondents participated in this study, comprising 470 males and 547 females aged between 16 and 25 years. Although the majority of young people fell into the normal-weight category (607 of them, p < 0.0001), some aspects can be noted that in the long term can produce a series of nutritional imbalances: an increased tendency toward sedentarism, with 553 (p = 0.613) of the respondents declaring that they performed sports rarely or not at all, and a tendency toward relatively high consumption of foods high in calories (fast food products and especially fried potatoes, hamburgers, shawarma, pastries, and snacks, along with sweetened drinks and even alcoholic beverages). The respondents participating in this study even indicated a perceived addiction to the consumption of certain products: coffee (50.48%), fried potatoes (38.9%), hamburgers (37.05%), shawarma (31.65%), and snacks (30.08%). Many of these products are rich in calories, saturated fat, and even trans fat. Conclusions: This study highlights a series of aspects that can have long-term negative effects related to the excess weight associated with other imbalances: consumption preferences among young people for hypercaloric fast food products, sweetened drinks associated with reduced physical activity, and even the development of some forms of food addictions for a series of hypercaloric foods.
