Fasting and postprandial hypertriglyceridemia are causal risk factors for atherosclerosis. The prevalence of hypertriglyceridemia is approximately 25–30% and most hypertriglyceridemic patients suffer from mild to moderate hypertriglyceridemia. Data regarding dietary interventions on postprandial triglyceride metabolism of mildly to moderately hypertriglyceridemic patients is, however, sparse. In a randomized controlled trial, eight mildly hypertriglyceridemic patients and five healthy, normolipidemic controls received three separate standardized fat-meals containing either saturated fatty acids (SFA), mono-unsaturated fatty acids (MUFA), or medium-chain fatty acids (MCFA) in a randomized order. Fasting and postprandial lipid parameters were determined over a 10 h period and the (incremental) area under the curve (AUC/iAUC) for plasma triglycerides and other parameters were determined. MCFA do not lead to a significant elevation of postprandial total plasma triglycerides and other triglyceride parameters, while both SFA (patients: p = 0.003, controls: p = 0.03 compared to MCFA) and MUFA (patients: p = 0.001; controls: p = 0.14 compared to MCFA) do lead to such an increase. Patients experienced a significantly more pronounced increase of plasma triglycerides than controls (SFA: patients iAUC = 1006 mg*h/dL, controls iAUC = 247 mg*h/dL, p = 0.02; MUFA: patients iAUC = 962 mg*h/dL, controls iAUC = 248 mg*h/dL, p = 0.05). Replacing SFA with MCFA may be a treatment option for mildly to moderately hypertriglyceridemic patients as it prevents postprandial hypertriglyceridemia.

Isocaloric modification in the ratio of dietary polyunsaturated-to-saturated fatty acids influences intestinal uptake of actively and passively transported nutrients. This study was undertaken to determine which dietary fatty acid was responsible for these alterations in absorption. Adult female rats were fed isocaloric semisynthetic diets high in palmitic and stearic acids (SFA), oleic acid (OA), linoleic acid (LA), or linolenic acid (LNA). An in vitro technique was used to measure the uptake of varying concentrations of glucose as well as a series of fatty acids and cholesterol. Jejunal uptake of 40 mM glucose was highest in rats fed SFA and lowest in those fed LA; ileal glucose uptake was similar in OA, LA, and LNA, but was lowest in SFA. Jejunal uptake of medium-chain fatty acids (8:0–12:0) was higher in OA than in other diet groups; ileal uptake of medium-chain fatty acids was unaffected by diet. Jejunal and ileal uptake of 18:2 was higher in LNA than in SFA or OA; the uptake of the other long-chain saturated or unsaturated fatty acids was unchanged by diet. The ileal but not the jejunal uptake of cholesterol was increased in LA as compared with SFA or OA, and reduced in LNA as compared with LA. These transport changes were not explained by differences in the animals' food consumption, body weight gain, intestinal mass, or mucosal surface area. We postulate that these diet-induced transport alterations may be mediated via changes in brush border membrane phospholipid fatty acyl composition. Thus, intestinal transport of nutrients may be varied by isocaloric changes in the dietary content of individual fatty acids.

Eight Holstein cows with body weight 570 ± 43 kg and 60 ± 20 lactation days were distributed in a double Latin square design with four 21-day periods to determine the effects of feeding ground or whole flaxseed with or without monensin supplementation (0.02% on a dry matter basis) on fatty acid profile of butter stored for 15 and 45 days. Ground flaxseed supply, in comparison to whole flaxseed, reduced relative percentages of 16:0, cis7-16:1, 17:0, and cis10-17:1 but it increased those of cis9,trans11-18:2, cis3-18:3, and omega 3 fatty acids in butter fat, reducing relative percentage of medium-chain fatty acids and increasing the content of polyunsaturated fatty acids. Supplementation with monensin increased relative percentages of cis9,trans11-18:2 and tended to increase relative percentage of 17:0 and decrease that of saturated fatty acids in butter. Butter from cows fed diet with monensin presented lower relative percentages of cis 6-20:4. Relative percentages of cis 9-16:1, cis10-17:1, 18:0, trans11-18:1, cis9-18:1, cis3-18:3, cis6-20:4 in butter stored for 15 days were higher than those stored for 45 days and the relative percentages of cis3-20:5 tended to decrease with the increase of storage period. As a result, relative percentages of saturated fatty acids and medium-chain fatty acids increased with storage time, while those of monounsaturated and long-chain fatty acids decreased. Butter enriched with polyunsaturated fatty acids may have a shorter shelf life due to the negative effect of storage on fatty acid profile which may cause oxidation and rancidity.

The nature of the fatty acid presented in each type of vegetable oil will determine the oil’s characteristic. The purpose of this review is to describe the medium chain fatty acids present in vegetable oils absorption mechanism and their benefits for human body, combined with technological advantages in the preparation of food formulations. Highlighting how the source of the raw material and the extraction method interfere with the concentration of fatty acids present in the oils. It is a review of narrative literature, which used as a theoretical framework recent scientific articles in the English language. Oils derived from coconut, palm kernel, and babassu, for example, have a solid or semi-solid characteristic at room temperature. This happens due to the presence of saturated fatty acids with medium-length carbon chains, that is from 6 to 12 carbons. Although medium-chain fatty acids are saturated, they present characteristics that are different from other long-chain saturated fatty acids. They are quickly digested by the body, which favors the absorption and the using of these nutrients, leading an impact on diseases’ control, such as obesity, diabetes and hypertension. In addition, due to their chemical structure, medium chain fatty acids can be used in the food industry as a substitute for animal fat, combining their nutritional benefits with technological advantage, being used in food preparations to impact texture, flavor, stabilize emulsions, and improve the rheological characteristics of the product.

Abstract Background The ketogenic diet (KD) can promote the anti-inflammatory metabolic state and increase ketone body level in rats. This study was to explore the effects and differences of KD with or without medium-chain fatty acids (MCFAs) on serum inflammatory factors and mTOR pathway in Sprague–Dawley (SD) rats. Results Male SD rats were assigned to five groups: control diet (C), 20% caloric restriction diet (LC), 20% caloric restriction ketogenic diet (containing MCFAs) (LCKD1), 20% caloric restriction ketogenic diet (LCKD2) and 20% caloric restriction foreign ketogenic diet (LCKD3), and fed for 30 d. LC and KD could significantly reduce the body weight of rats; LC and KD containing MCFAs showed anti-inflammatory effects; KD without MCFAs decreased the concentration of mTOR1, while KD containing MCFAs decreased the expression of AMPK, mtor1 and P70sk. Conclusions KD containing MCFAs showed better effects on the mTOR pathway and anti-inflammation than that without MCFAs.
