Abstract There is evidence that algae can be a sustainable alternative of omega-3 polyunsaturated fatty acids (w-3 PUFA; DHA and EPA) in the diets of felines, but more information is needed to determine bioavailability of algal w-3 PUFAs in felines. Therefore, the objective of this study was to determine the effects of dietary supplementation of algae DHA on plasma and red blood cell (RBC) membrane fatty acid profiles and fecal microbiota of adult cats. A complete randomized design was utilized with thirty female and male adult cats (mean age: 1.8 ± 0.03 yr, mean BW: 4.5 ± 0.8 kg) which were fed an assigned diet for 90 d. Three diets were formulated with poultry fat alone or inclusion of 2% fish oil or 2% algae DHA meal. Blood samples were collected after fasting on 0, 30, 60 and 90 d to be analyzed for plasma and red blood cell fatty acid profiles. A fresh fecal sample was collected within 15 min of defecation from each cat to be analyzed for fecal microbiota. Illumina 16S rRNA sequencing from V4 region was completed using MiSeq and analyzed using QIIME 2. Plasma and RBC fatty acid concentrations at baseline were similar among all cats and treatment groups. However, dietary treatment had a significant effect on the concentrations of several fatty acids in plasma and RBC over time. Plasma and RBC concentrations of DHA were greater (P < 0.05) for cats fed the algal DHA diet compared to the control and fish oil diets. Conversely, plasma and RBC concentrations of EPA did not differ among treatments when analyzed as a change from baseline. Beta- and alpha-diversity did not differ among treatments, indicating that 2% fish oil or algal-DHA meal does alter fecal microbiota of cats in contrast with cats fed a poultry fat-based diet.

The present study evaluated the effects of moderate intakes of myristic acid (MA), at 1·2% and 1·8% of total energy (TE), associated with a 0·9% TE intake of α-linolenic acid (ALA) on lipid and fatty acid profiles and red blood cell membrane fluidity. Twenty-nine monks without dyslipidaemia were enrolled in a 1-year nutritional study in which two experimental diets were tested for 3 months each: diet 1, MA 1·2% and ALA 0·9%; diet 2, MA 1·8% and ALA 0·9%. A control diet (MA 1·2%, ALA 0·4%) was given 3 months before diets 1 and 2. Thus, two different levels of MA (1·2%, 1·8%) and ALA (0·4%, 0·9%) were tested. Intakes of other fatty acids were at recommended levels. Samples were obtained on completion of all three diets. For fluidity analysis, the red blood cells were labelled with 16-doxylstearate and the probe incorporated the membrane where relaxation-correlation time was calculated. Diet 1 was associated with a decrease in total cholesterol, in LDL-cholesterol, in triacylglycerols and in the ratio of total to HDL-cholesterol; ALA and EPA levels were increased in both phospholipids and cholesterol esters. Diet 2 was associated with a decrease in triacylglycerols and in the ratios of total to HDL-cholesterol and of triacylglycerols to HDL-cholesterol, and with an increase in HDL-cholesterol; EPA levels were decreased in phospholipids and cholesterol esters. Red blood cell membrane fluidity was increased in both diets (P<0·0001), but the higher increase was obtained with diet 1, mainly in the oldest subjects. Intakes of myristic acid (1·2%TE) and ALA (0·9%TE), both mainly in the sn-2 position, were associated with favourable lipid and n−3 long-chain fatty acid profiles. These beneficial effects coexisted with particularly high membrane fluidity, especially among the oldest subjects.

AbstractObjectivesTo assess dietary fatty acid intakes and to examine the relationship between dietary sources ofn-3 andn-6 PUFA and red-blood-cell (RBC)n-3 andn-6 PUFA composition.DesignA cross-sectional study. Dietary intakes were assessed with a 24 h dietary recall. A second recall was performed for 44 % of the children. Usual dietary intakes were estimated with the Software for Intake Distribution Estimation (SIDE). The fatty acid composition was measured in RBC membranes. Multivariate linear regression analyses were performed to explain RBCn-3 andn-6 PUFA concentrations.SettingChild-care centres in Nunavik, northern Québec, Canada.SubjectsOne hundred and sixty-seven Inuit children aged 11–53 months.ResultsA high proportion of the participants had inadequaten-3 andn-6 PUFA intakes (47·9 % and 93·5 %, respectively). Breast-feeding status and consumption of traditional food during the first 24 h dietary recall were significantly associated with RBCn-3 PUFA levels. Older children also tended to have higher RBCn-3 PUFA levels (P= 0·0528), whereas sex, infant formula status andn-3 PUFA dietary intakes were not associated with RBCn-3 PUFA concentrations. RBCn-6 PUFA concentrations were positively associated with breast-feeding status andn-6 PUFA dietary intakes, whereas age, sex and infant formula status were not.ConclusionsThe present findings highlight the fact that Inuit pre-school children are not consuming enoughn-3 andn-6 PUFA for optimum health. These observations call for actions to increase traditional food intake among Inuit children and to help them and their parents make healthier store-bought food choices.
