Presented in the paper are three eating patterns for convalescents following the coronavirus disease (COVID-19). Eating pattern no. 1 involves an increased content of complete protein necessary for recovery of the immune system. Eating pattern no. 2 includes a higher content of carbohydrates and polyunsaturated fatty acids, i. e. a high energy value of the food intake, as well as a lower content of cooking salt. It enhances an anti-inflammatory effect while polyunsaturated fatty acids increase the number of T-cells, decrease the concentrations of TNF and BSF2. Eating pattern no. 3 is advisory for patients with dyspeptic disorders as a result of an acute infectious disease.

Inflammatory Effect

Polyunsaturated fatty acids (n-3 PUFAs) are long-chain polyunsaturated fatty acids with 18, 20 or 22 carbon atoms, which have been found able to counteract cardiovascular diseases. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), in particular, have been found to produce both vaso- and cardio-protective response via modulation of membrane phospholipids thereby improving cardiac mitochondrial functions and energy production. However, antioxidant properties of n-3 PUFAs, along with their anti-inflammatory effect in both blood vessels and cardiac cells, seem to exert beneficial effects in cardiovascular impairment. In fact, dietary supplementation with n-3 PUFAs has been demonstrated to reduce oxidative stress-related mitochondrial dysfunction and endothelial cell apoptosis, an effect occurring via an increased activity of endogenous antioxidant enzymes. On the other hand, n-3 PUFAs have been shown to counteract the release of pro-inflammatory cytokines in both vascular tissues and in the myocardium, thereby restoring vascular reactivity and myocardial performance. Here we summarize the molecular mechanisms underlying the anti-oxidant and anti-inflammatory effect of n-3 PUFAs in vascular and cardiac tissues and their implication in the prevention and treatment of cardiovascular disease.

The Brain

In mammals, brain function, particularly neuronal activity, has high energy needs. When glucose is supplemented by alternative oxidative substrates under different physiological conditions, these fuels do not fully replace the functions fulfilled by glucose. Thus, it is of major importance that the brain is almost continuously supplied with glucose from the circulation. Numerous studies describe the decrease in brain glucose metabolism during healthy or pathological ageing, but little is known about the mechanisms that cause such impairment. Although it appears difficult to determine the exact role of brain glucose hypometabolism during healthy ageing or during age-related neurodegenerative diseases such as Alzheimer’s disease, uninterrupted glucose supply to the brain is still of major importance for proper brain function. Interestingly, a body of evidence suggests that dietary n-3 polyunsaturated fatty acids (PUFAs) might play significant roles in brain glucose regulation. Thus, the goal of the present review is to summarize this evidence and address the role of n-3 PUFAs in brain energy metabolism. Taken together, these data suggest that ensuring an adequate dietary supply of n-3 PUFAs could constitute an essential aspect of a promising strategy to promote optimal brain function during both healthy and pathological ageing.

The objective of the study was to assess the influence of gender, age, and carcass weight on the properties of meat from adult horses slaughtered in Lithuania. M. pectoralis profundus of twenty-six obsolescent horses from 3 to 21 years of age were used in the experiment. Gender appeared to affect the horse meat properties. Stallions demonstrated (p < 0.01 and p < 0.05, respectively) lower content of dry matter and also considerably lower (p < 0.001 and p < 0.01) intramuscular fat content compared with mares and geldings and higher (p < 0.01) cholesterol content compared with mares. The meat of stallions showed the highest pH; however, a significant (p < 0.01) difference was obtained only in comparison with mares. Meat lightness (L*) and yellowness (b*) of stallions were lower (p < 0.05) compared with geldings. Meat toughness of stallions was also lower (p < 0.01) than the meat of mares and geldings. The highest (p < 0.05 and p < 0.01, respectively) proportion of total polyunsaturated fatty acids (PUFA), higher (p < 0.05) and more favorable PUFA/SFA ratio, and also the highest (p < 0.05) but least favorable n-6/n-3 PUFA ratio, were detected in the muscles of stallions compared with mares and geldings. The differences in horse ages did not exhibit any effect on the properties of M. pectoralis profundus. Despite the age differences at the decline of horse life, the properties of the horse meat exhibited good quality and showed that horse meat is potentially highly beneficial to human health.

Bothriocephalus Acheilognathi

The changes in total lipids, their fatty acid composition and the ratio of individual classes were established in tissues of the intestine, hepatopancreas and skeletal muscles of carp (Cyprinus carpio Linnaeus, 1758), with body weight 14.5–20.5 g, at different rates of invasion by Bothriocephalus acheilognathi (Yamaguti, 1934) helminth, which belongs to the family Bothriocephalidae, of the Pseudophyllidae order, of the Cestoda class. The examined carp was divided into three groups: first group of fish was free from intestinal helminths of B. acheilognathi (control); second group of fish was weakly infected with helminths (intensity of invasion is 1–3 helminths per fish); the third group of fish was highly infected (the invasion intensity is 4 worms and more per fish). Our results showed that fish infected with helminth B. acheilognathi compared to uninfected fish had reduced total lipid level in the gut due to phospholipids, triacylglycerols, and also lipids were characterized by lower content of linoleic, linolenic, arachidonic, penta- and hexanoic fatty acids; decrease in the level of unsaturated and increase in the content of saturated fatty acids, which leads to an increase of the saturation factor. During the infection of carp with B. acheilognathi in the hepatopancreas, the content of total lipids, structural lipids – phospholipids and reserve energy sources – triacylglycerols is probably reduced, and lipids are characterized by a high content of saturated fatty acids (С14:0, С16:0, С18:0) and lower content of unsaturated: arachidonic (С20:4), linolenic (С18:3) and linoleic acid (С18:2), which is associated with a decrease in the source for the synthesis of a number of polyunsaturated fatty acids, especially docosahexaenoic (С22:6). The total content of lipids, triacylglycerols, free fatty acids and phospholipids in skeletal muscle of carp during the Bothriocephalus invasion decreased and the content of free cholesterol, mono- and triacylglycerols increased. Helminth B. acheilognathi has the effect of reducing the total lipids of the skeletal muscle content of С18-, С20-, С22-polyunsaturated fatty acids and increasing the content of saturated (С14:0, С16:0, С18:0) and monounsaturated (С16:1, С18:1) fatty acids. The obtained results prove that the parasite B. acheilognathi in the intestine of the carp significantly affects the nutrition processes of the host depending on the intensity of the damage by helminths, which is accompanied by impaired lipid metabolism.

Different Ages

This study aimed to evaluate the cholesterol content, ?-tocopherol and fatty acids in the meat of Nellore young bulls or steers castrated at different ages, 13 or 18 months. The animals were confined for 100 days and slaughtered at 22 months of age. The experimental design was completely randomized with three treatments, using 12 repetitions. The levels of palmitic acid (26.39%), stearic (24.39%), myristic (3.01%) and total saturated fatty acids were not altered by sexual condition or castration age. Oleic was the fatty acid with the highest average participation in the meat (34.54%), and lower content in the meat of young bulls in relation to the castrated. The content of total unsaturated fatty acids was lower in the young bulls in relation to castrated at 18 months, which did not differ from castrated at 12 months. The content of total polyunsaturated fatty acids was increased by elevation of the castration age, being similar between young bulls and castrated at 18 months. The ratio ?6/?3 was not altered by sexual condition or castration age. Castration at the beginning of the finishing period increases the content of beneficial fatty acids to health in relation to castrated in the first third of backgrounding.
