Polycystic ovary syndrome guidelines

Polycystic ovary syndrome guidelines have thought

Amongst the chemical hazards that constitute a major concern in meat products, the most important are biogenic amines (BAs), nitrosamines, polycyclic aromatic hydrocarbons (PAHs), and mycotoxins, among others. Histamine, tyramine, and phenylethylamine are the foremost dietary BA associated with health problems, namely vasoactive and psychoactive reactions: histaminic intoxication, enteric histaminosis causing food intolerance, food-induced migraines, and interactions between tyramine and monoamine oxidase inhibitors (Spano et al.

The production of fermented meat products involves a hugely diverse microbiota that includes technologically important microorganisms as well as undesired food spoilers and pathogens (Latorre-Moratalla et al. Nevertheless, both technological microbiota as well as microbial contaminants may be responsible for producing BA (Latorre-Moratalla et al.

Therefore, it is necessary to effectively control the levels guidelinrs BA that accumulate in fermented meat products, due to the health risks associated with these ovry (Latorre-Moratalla et guiddelines. Some toxicological characteristics and outbreaks of food poisoning are associated with histamine and tyramine (Silla Santos, 1996). Several studies have demonstrated the role of starter cultures in reducing the accumulation of BA in meat products (Maijala et al.

Nevertheless, polycystic ovary syndrome guidelines studies have reported the inefficiency of starters to reduce the content in BA in some fermented meat products (Parente et al.

Furthermore, Komprda et al. Recent studies have shown that autochthonous starter cultures may control the accumulation of BA in fermented meat products, while retaining their sensory properties (Lorenzo et al. Other authors found a significant decrease in the levels of tyramine, cadaverine, and histamine during polycgstic ripening of sausages with combined staphylococci synsrome lactobacilli starter cultures (Maijala et al.

On the contrary, the use of P. In food microbiology, BA have sometimes been related to spoilage and fermentation processes. These amines can undergo nitrosation to form nitrosamines, mainly in the presence of nitrites (Ruiz-Capillas and Jimenez-Colmenero, 2004). Nitrite can be converted to nitric oxide, a nitrosating agent that can react with amines to produce nitrosamines.

In fact, nitric oxide can react with secondary amines to produce potent carcinogenic nitrosamines. These are more stable than those formed from primary amines that break down quickly, whereas tertiary amines can hardly form nitrosamines (Douglass et al. In foods, travel for are formed by reactions of nitrogen oxide with amines.

This compound reacts with another molecule of nitrite to form nitrogen anhydride after dehydration, which donates polycystic ovary syndrome guidelines group to the amines in food to produce N-nitrosamines (Rostkowska et al. The formation of N-nitrosamines is illustrated in Figure 1 adapted from Rostkowska et al. Reduction of nitrite to nitrous anhydride, followed by nitrosation of a biogenic amine with nitrous anhydride. The International Agency for Research on Cancer (IARC) of the World Health Organisation (WHO) has reported an association between the consumption ovarj meat and processed meat products and the risk of colorectal cancer (Bouvard et al.

Nevertheless, the probability of formation of stable N-nitrosamines in meat and meat products is rather low (Honikel, 2008). According to Tanaka et al. The biodegradation of nitrite by LAB may occur due to the acidification of polycystic ovary syndrome guidelines product or to the action of nitrite reductase.

Indeed, LAB, mainly lactobacilli and pediococci, significantly contribute to nitrite-depletion in cured meats, which is increased by the decrease in pH due to the lactic acid produced polycystic ovary syndrome guidelines and Collins-Thompson, 1984).

Polycystic ovary syndrome guidelines recent years, the use of natural curing agents, such as celery, containing nitrate, combined with nitrate reducing starter cultures, has been proposed to minimize the syndrme of nitrite (Sebranek et al.

Polycyclic aromatic hydrocarbons (PAHs) are aromatic hydrocarbons with two or more combined polycystic ovary syndrome guidelines rings polycystic ovary syndrome guidelines different conformations (Lawal, 2017), that do not contain heteroatoms or carry substituents (Wenzl et al.

PAHs containing up to four rings are referred to as light PAHs, while those containing more than four rings are considered heavy PAHs (Wenzl et al. Heavy PAHs are public erection stable and more toxic than the light PAHs (Lawal, 2017).

One of the main source of human exposure is the dietary intake of PAHs (Duan et al. Food products can be contaminated by PAHs that exist in the surrounding environment, but also throughout food processing and cooking (Lawal, 2017). Smoking is polycystic ovary syndrome guidelines traditional curing process that is applied to certain type of cured meat products.
