Caffeine is a natural compound found in coffee, tea and cocoa. It is a central nervous system stimulant and is probably the world's most widely consumed psychoactive drug. While the ingestion of caffeine was previously considered to have the potential for causing harmful effects, recent studies have provided evidence of several health benefits.
The effect of caffeine on the digestive system is still not clear. For example, recent studies suggest that caffeine alters salivary alpha amylase activity, but the results are contradictory. Other studies report that caffeine interacts with trypsin to form a caffeine-trypsin complex. However, the significance of this finding is unclear.
The aim of this study was to further investigate in vitro the effects of caffeine on the activity of alpha amylase, and of trypsin, using a spectrophotometric method. Starch and BSA (Bovine Serum Albumin) solutions were used as substrates to investigate alpha amylase and trypsin in-vitro degradation, respectively.
It was found that caffeine significantly inhibited both alpha amylase and trypsin activity in a dose-dependent manner.
We postulate that the inhibition of alpha amylase caused by caffeine may reduce the level of various sugars in the small intestine, thereby reducing the amount of glucose that is absorbed into the bloodstream. This may be beneficial in, for example, diabetic or obese individuals.
Our findings also suggest that caffeine administration may reduce amino absorption from the gastro-intestinal tract. The significance of this effect is unclear.

Galactooligosaccharide are prebiotics that changes the composition of gastrointestinal microbiota conferring bifidogenic effect on the gut. The purpose of this study was to assess the impact of Galacto-Oligo-Saccharide (GOS) gummies’ supplementation on gut health and constipation profile of sedentary adults. University teaching faculty who were constipated (n=35) were screened using validated pre-tested questionnaires. Eight parameters were studied including Rome IV criteria, WHO definition and Bristol Stool Chart. They were subjected to a double blind placebo controlled clinical trial (Figure 1). The participants were split into two groups; the experimental group (n=17) received 100% GOS gummies, while the placebo group (n=18) received sugar gummies for 30 days. Fecal samples were collected at baseline and Day 30. The relative abundance of genera including Bifidobacterium, Lactobacillus, Clostridium, Bacteroides and phyla Bacteroidetes and Firmicutes were examined using Real-Time PCR. Normalization of gene expression was done using 16s rRNA. SCFA profile was studied using gas chromatography technique with respect to Acetic acid, Butyric acid and Propionic acid as SCFA is linked with increased colonization of beneficial bacteria. The experimental group experienced a significant increase in stool frequency by 40% (p<0.01) and significant reduction of gastrointestinal symptoms. In contrast to the placebo group, the results showed a significant increase in the genera Bifidobacterium (p<0.001), Lactobacillus (p<0.001) in the GOS supplemented subjects. However, genus Clostridium (p<0.01), phyla Firmicutes (p<0.001) and Bacteroidetes (p<0.001) were found to be reduced significantly, particularly in the GOS supplemented group. In comparison to the placebo group (1.29), it was observed that the GOS supplemented group had a higher F/B ratio (2.57) which correlates to an improved gut health. Significant increase in Acetic acid (p<0.001) and butyric acid (0.01) was observed among the experimental group making it evident that short-term GOS consumption can relieve constipation status and result in improved gut health profile of constipated subjects.

Title: Development and physio-chemical evaluation of fermented fruit pulp
Mayuri Rastogi, BSc, MSc (Food and Nutrition, 2007) and pursuing PhD. She is working as assistant Professor in Sharda University from last 5 years. Prior to this she worked for 7 years in multispecialty hospitals as clinical Dietician. Her area of interest is micronutrients role and intervention studies.
Introduction: Nutrients especially water-soluble vitamins are vital for health and the requirements can be only met by oral or intramuscular route. Diet plays an essential role in fulfilling daily vitamin dose; however, lack of awareness, poor nutrient absorption and indigestibility leads to deficiency of water-soluble vitamins. The microbial production of vitamins provides a naturally and economically interesting approach to improve the nutrient content in fermented foods. The benefit of fermented foods for consumer is not only limited to enhance B12 vitamins but also a good source of antioxidants and improved antimicrobial, probiotic and organoleptic qualities.
Materials and methods: Pineapple pulp was fermented with Lactobacillus plantarum and produce nutrient rich fruit probiotic. Different sucrose concentration was checked for different parameters such as duration, acidity and viable cell count. After 48 hrs of incubation at 37oC, the viable cell count was measured. Physico-chemical analysis was done for analysis of Protein, sugars and Tithable acidity using standard protocols.
Results: Fermentation was done for 48 hrs and the CFU was observed 6.0 ± 0.1 to 8.10 ± 0.38 log CFU/mL, at the same, pH decreased to acidic (3.4-3.5). Phytochemical analysis showed that, the protein content 2.84 gm per 100 gm, reducing sugar 17.5%, Nonreducing sugar 5.83%, Total Sugar 23.5%, titrable acidity 0.373%.
Conclusion: It is possible to ferment pineapple pulp with Lactobacillus plantarum and create a delightful jelly. The entire product is formed by microbial fermentation, using Generally Recognized as Safe (GRAS) bacterium

The increased prevalence of iron deficiency among infants aged 6 and 24 months can be attributed to the consumption of an iron deficient diet or a diet that interferes with iron absorption at the critical time of infancy. The objectives of the study were to determine iron status among infants, to determine dietary intake of complementary foods by the infants and to ascertain the complementary feeding in Keiyo South Sub County. The cross-sectional study design was adopted. The study was conducted at Soy division in Keiyo South Sub County at Biretwo, Cheptebo and Sego health facilities. Systematic sampling procedure was used to select 136 subjects. In the second year, 54 mothers were followed up due to loss of subjects. The 24 -hour recall generated data on dietary iron intake. Biochemical tests were carried out by use of the portable Hemo_Control Photochrometer device at the health facilities. Data was analyzed using SPSS computer software version 17, 2009.
Results showed that 28.7% of the infants had mild anemia whereas 23.5% had moderate anemia. The mean iron intake was 10.59 ± 1.71 mg/day. Most (94.1%) of the mothers were still breastfeeding but on the contrary, 45.6 % of all the mothers fed their infants on tea which is an iron inhibitor. None of the infants had received iron supplements. Policies for screening infants for iron deficiency during the first year of life should be developed as the iron deficiency anemia is a problem in Kenya.
