Regarding the potential application of LAB to reduce wheat allergy, in vitro studies carried out in cell model, demonstrated that probiotic Bifidobacterium lactiswas able to inhibit the toxic effects caused by the ingestion of wheat gliadin. Some authors found that Lactobacillus rhamnosus GG may contribute to improving gut permeability, presenting potential to prevent the disruption of the gut epithelial barrier caused by this protein. Other results also suggested that the administration of probiotics, such as Bifidobacterium animalis subsp. lactis BB-12, Lactobacillus acidophilus, and Lactobacillus rhamnosus GG could suppress the production of specific IgE (Lindfors et al. 2008, Orlando et al. 2014, Paparo et al. 2019b). Still on this matter, De Angelis et al. 2007 observed that commercial probiotic VSL#3, used as starter for dough fermentation, was able to provoke extensive hydrolysis of wheat proteins, cleaving some IgE-binding antigens. Besides, the authors reported that the remaining IgE-binding proteins were completely hydrolyzed by pepsin and pancreatin after simulated digestion.
Dairy Product Consumption, Dairy Fat, and Cardiometabolic Health*

Finally, the impact of consuming fermented dairy products on plasma lipid levels has been of interest for more than 30 years. Agerholm-Larsen et al. (2000a) published a meta-analysis of six RCTs on Gaio®, a commercially available yogurt fermented with one strain of Enterococcus faecium and two strains of Streptococcus thermophiles. Data indicated that consumption of the fermented yogurt significantly reduced plasma LDL-C compared with consumption of control yogurts, which were of identical composition to the test yogurt, but chemically fermented with an organic acid instead of a live bacterial culture. Such data have been reproduced in some (Anderson and Gilliland 1999; Andrade and Borges 2009) but not all (de Roos et al. 1999; Sadrzadeh-Yeganeh et al. 2010) of the more recent studies of fermented dairy intake. Finally, consumption of fermented dairy of any form seems to have very little impact on plasma TG (Schaafsma et al. 1998; Bertolami et al. 1999; St-Onge et al. 2002; Hansel et al. 2007), while the effects on HDL-C concentrations have not been investigated thoroughly. In a small parallel RTC, we have shown that 4-week consumption of yogurt products containing different doses of Bifidobacterium animalis subsp. lactis (BB-12) and Lactobacillus acidophilus (LA-5) had no significant impact on plasma LDL-C, TG, and HDL-C concentrations compared with a control yogurt (Savard et al. 2011). This is an area that certainly deserves intensified research.
Patulin
Dongyou Liu in Handbook of Foodborne Diseases, 2018
Different works postulated biodetoxification as an effective method for removing patulin of the media. Fuchs et al. [146] found a strain of Bifidobacterium animalis that reduced 82% of the patulin in liquid medium. The best conditions for the adsorption of patulin were pH 5, and a high amount of bacteria in the medium (≥108 CFU/mL). Also, it was demonstrated that the viability of the cells played an important role in the detoxification process, suggesting that a mechanism other than binding to the cell walls (e.g., metabolic conversion by the release of specific enzymes) could be involved. Different yeast strains have been described as in vitro degraders of patulin.

B. infantis 35624 and B. breve YIT10347 activate the intestinal DCs by interacting with TLRs and stimulating RA metabolism. As a result, DCs activation elevates the expression of IL-10 and the number of Foxp3+ Treg and type 1 regulatory T (Tr1) cells. Moreover, L. rhamnosus GG and L. acidophilus can reduce the number of Th17 cells and the expression of IL-23 and IL-17 cytokines through prevention of STAT3 and NF-κB signaling and further shift the balance between pro-inflammatory M1 and immunosuppressive M2 macrophage toward M2 phenotype.178 In contrast, Bifidobacterium animalis spp. lactis Bl 5764 is able to promote IL-17A expression by CD4+ T lymphocytes in vitro. L. reuteri Lr 5454 co-culture with DCs can promote Tregs, and regenerating islet-derived protein 3-beta (Reg3b) expression in a NOD2-dependent manner and further induce IL-22 production.179 IL-22 plays an imperative role in preserving gut homeostasis and tissue regeneration. Furthermore, this cytokine accelerates the colonization of Phascolarctobacterium bacterium and thereby prevents C. difficile infection (CDI).180

Early researches on prebiotics were mainly focusing on plant foods that contain inulin, polyphenols, fructo- or galactooligosaccharides. More recently, certain functional foods, such as Geranium dielsianum tea, cassava bagasse flour, and kiwifruit pectins, have also been reported for their prebiotic effects.23–25Gynostemma pentaphyllum is a dietary herbal medicine known for its many health benefits. In our previous studies, we demonstrated that triterpenoid saponins from Gynostemma pentaphylum together with ginseng, rotoginseng display prebiotic-like effects in the normal mouse model.26 Further research showed that G. pentaphylum saponin (GpS) exerts significant cancer-preventive effects in ApcMin/+ mice through modulating the GM composition and the gut epithelial microenvironment.27–29 We hypothesize that treatment with GpS might have preserved a particular group(s) of bacteria that provides health advantage to the host. In this current study, we performed both in vivo and in vitro experiments to track down the potential bacterial group(s) that confers the prebiotic and cancer-preventive effect of GpS. We provide evidence that Bifidobacterium animalis might be the critical gut microbe contributing to the anticancer and cancer-preventive activities of GpS against colonic cancer.

Clinical studies suggest that some probiotic bacteria can promote health and prevent disease;1,8,21,22 however the mechanisms underlying these beneficial effects are not well understood. In this study, the in vivo effect of Bifidobacterium animalis subspecies lactis (Bb12) on intestinal function and immunity against a parasitic nematode was evaluated. Ascaris suum is a persistent and common problem in swine raised worldwide, and the related species in humans, A. lumbricoides (large roundworm) infects an estimated 804 million people.23 Although infections are common in countries with poor sanitation, ascariasis exhibit a cosmopolitan distribution with sporadic cases also described in developed countries24 where pigs can be a source of infection.25 Examination of the immunological and physiological responses to intestinal helminths also has been used to study local and systemic allergic disease.26,27
