Background: UK Government recommendations for dietary fibre intakes have recently increased to 30 g per day, well below current population intakes. Aim: This study aimed to explore whether the target for dietary fibre intake could be achieved and the effects on markers of cardiometabolic health. Methods: In this 4-week high-fibre intervention study, 15 participants were instructed to achieve dietary fibre intakes of 30 g/day. Results: Dietary fibre intakes significantly increased post intervention (16.0 ± 8.1 g/day, p < 0.001). No significant changes in glucose and triglyceride concentrations were observed and there was a significant increase in average body weight (0.7 ± 1.2 kg, p = 0.025). Conclusions: This study shows that achieving the new dietary fibre recommendations of 30g/day is achievable, in the short term, in a sample of British adults without any observed effect on health markers.

1. Twelve young adult male volunteers were given a low-fibre white bread diet (9 g neutral-detergent fibre (NDF)/d) and a medium-fibre coarse-bran bread diet (22 g NDF/d), each lasting 20 d. In a third period of 20 d the volunteers were subdivided in groups of four, consuming a high-fibre coarse-bran bread diet (35 g NDF/d). a medium-fibre fine-bran bread diet (22 g NDF/d, bran particle size < 0.35 mm) or a wholemeal bread diet (22 g NDF/d), Retention of calcium, magnesium, iron, zinc and copper were determined during each 20 d period.2. An increase of the amount of dietary fibre (through bran in bread) from 9 g to 22 g NDF/d resulted in a significantly increased mineral intake, but also faecal excretion increased significantly; mineral retention remained almost constant.3. Both intake and faecal excretion of all minerals studied, except faecal Ca. increased further (P < 0.05) on the diet providing 35 g NDF/d: only Fe balance decreased significantly. No significant differences with respect to intake, excretion (except urinary Ca) and balance of the minerals could be detected between the coarse-bran bread and fine-bran bread diets providing 22 g NDF/d. Faecal Fe, Cu balance and Mg balance increased significantly during the wholemeal bread period compared to the coarse-bran bread diet providing 22 g NDF.4. Serum cholesterol increased significantly, i.e. by 0.3 mmol/1, during the coarse-bran bread diet providing 22 g NDF, compared to the white-bread diet.5. It is concluded that increasing the amount of bran in bread does not appear to affect mineral balance considerably but there seems to be an influence on mineral availability. The increased intake was accompanied by increased faecal excretion.

AbstractAn experiment was conducted to examine the effects of dietary fibre and starch levels on the response to condition score at calving. Fifty-two cows were used over two winter feeding periods, with 24 and 28 different cows in each. Twelve weeks before their expected calving date, cows were paired and the level of feeding adjusted to attain mean condition scores at calving of 2·0 (T) and 3·5 (F) within pairs. At calving, pairs of cows were allocated to treatment HF or LF, giving four groups in total. Each day for the first 16 weeks of lactation, all cows were offered 10 kg dairy concentrate containing either high-fibre/low-starch (FHF and THF), or low-fibre/high-starch (FLF and TLF), 2 kg sugar-beet pulp and hay ad libitum. Two cows from each group were used to determine apparent digestibility of the whole diet each year, using chromium III oxide as a faecal marker. Eight steers were used to determine the degradabilities of dry matter, nitrogen and fibre in the two concentrates and to provide rumen fluid samples for volatile fatty acid determination.

Dietary fibre is fermented by the gut microbiota and protects against the development of cardiovascular disease (CVD) through the production of gut microbial metabolites. We hypothesised dietary fibre intake during pregnancy may prevent the development of CVD in the offspring via in utero epigenetic mechanisms. To investigate this, we fed C57BL/6J female mice diets high or low in resistant starches (‘high-fibre’ and ‘low-fibre’, respectively) during gestation. At 6-weeks of age, we performed single-cell RNA-sequencing in the offspring (n=8/group) or they were challenged with saline (sham) or angiotensin II (Ang II, 0.25mg/kg/day, n=18-23/group). Maternal diet resulted in a distinct gut microbial composition ( P =0.001). This was still evident in the adult offspring, with high-fibre offspring having a different gut microbial colonisation ( P =0.001), irrespective of sham/Ang II treatment. Maternal fibre intake significantly changed the cardiac cellular and molecular landscape and promoted differential gene signatures in the offspring. This included upregulation of genes associated with extracellular matrix production in the offspring from low-fibre mothers. When challenged with Ang II, low-fibre offspring developed increased cardiac hypertrophy ( P =0.034) and fibrosis ( P =0.01) compared to high-fibre offspring. This was accompanied with decreased ejection fraction ( P =0.001) and increased left ventricular posterior wall thickness ( P= 0.017). These changes were independent of blood pressure. High-fibre offspring had decreased expression of natriuretic peptides ( Nppa , P =0.03, Nppb , P =0.002) compared to low-fibre offspring. Chromatin-immunoprecipitation assay revealed decrease in H3-acetylation at the cis-regulatory region of Nppa gene in Ang II-treated high-fibre offspring (P=0.002), suggesting that maternal fibre intake influences the epigenetic changes of the Nppa gene in the offspring’s heart. Together, these data reveal maternal high-fibre intake leads to foetal epigenetic reprogramming, likely through maternal to foetal transfer of gut microbial-derived metabolites.

The effect of dietary fibre on the gastric emptying rate of solids is controversial. Similarly, the mechanisms by which it modulates food intake are partially unknown. Gastric emptying and proximalv.distal stomach filling were evaluated in triplicate on four conscious pigs using scintigraphic imaging. Each animal received in an isoenergetic manner a concentrate low-fibre diet enriched in starch (S) and two high-fibre diets based on sugar beet pulp (BP) or wheat bran (WB). All meals had the same viscosity before ingestion (100.0–100.5 Pa.s). Viscosity of the gastric contents was measured in four additional animals fitted with a gastric cannula. The gastric emptying rate of BP diet was significantly slower than S and WB diets (t1/278.4 (SEM 5.68), 62.8 (sem 10.01) and 111.6 (sem 10.82) min for S, WB and BP diets respectively,P<0.05). For BP diet only, rate of distal stomach filling was steady during the first 120 min after the meal whereas that of S and WB diets decreased in an exponential manner. Numerous backflow episodes from the distal into the proximal stomach were observed for BP diet that generated the larger intragastric viscosity (0.26 (sem 0.03), 0.3 (sem 0.02) and 0.52 (sem 0.002) Pa.s for S, WB and BP respectively). In conclusion, viscosity of the meal or the percentage total fibre, unlike viscosity of the gastric contents, are poor predictors for emptying. The reduced emptying rate observed with BP is associated with major changes in intragastric distribution of the meal absent with WB and S diets.
