Abstract

The present invention relates to a food composition beneficial for gastrointestinal tract. We have found that one of the ways human bodies can resist harmful viruses by producing Antimicrobial Peptides (AMPs). However, a few interventions can boost human body's ability to enhance production of such AMPs. It is thus an object of the present invention to provide a food product for boosting Antimicrobial Peptides (AMPs) in the intestinal epithelial cells of the gastrointestinal tract. The present inventors while working on this have surprisingly found that a food product that comprises a vitamin B3 compound or its precursors or analogues thereof; and an edible PPAR fatty acid preferably a hydroxy fatty acid having number of carbon atoms from 6 to 20 is able to boost the AMP generation in the intestinal epithelial cells of the gastrointestinal tract and thereby protecting against the viruses. Furthermore, the present inventors have found that this effect provides for inactivation or killing of enveloped virus in the intestinal epithelial cells of the gastrointestinal tract.

Description

A FOOD PRODUCT
Field of the Invention
The present invention relates to a food composition. More particularly, the present invention relates to a food composition beneficial for gastrointestinal tract.
Background of the Invention
Food is the most suitable way to deliver benefits to the gastrointestinal tract which is one of the vital internal organs of human body. When viruses enter the human body either through the respiratory tract or by consuming food contaminated with such viruses, they cause disturbances in the way the intestine (both small and large) works. This in turn causes an upset stomach, diarrhea, stomach flu and other relates problems.
More recently, SARS COV-2 (COVID 19), a coronavirus which has caused immense suffering in the world, was also found to be causing gastrointestinal problems. One of the symptoms of COVID 19 infection is found to be stomach related issues. Other than COVID 19, there are other enveloped viruses which causes similar problems.
We have found that one of the ways human bodies can resist such viruses is by producing Antimicrobial Peptides (AMPs). This is known to be human body’s own defense mechanism. However, a few interventions can boost human body’s ability to enhance production of such AMPs.
AMPs were initially discovered in insects and in animals and ever since their initial discovery AMPs are regarded as promising antimicrobials. AMPs are ubiquitous in nature, and they typically exhibit a broad spectrum of activity against invading bacteria, fungi, enveloped viruses and parasites (Braff and Gallo, 2006). AMPs are generally short peptides and in humans about 90 different AMPs are reported to be present. AMPs, in general, have two major physical features and they are - a) presence of cationic charge and b) a significant proportion of hydrophobic residues. The cationic charge of the AMPs promotes selectivity for negatively charged microbial cytoplasmic membranes whereas the hydrophobicity facilitates interactions with the cell membrane of the microbial species.
It is thus an object of the present invention to provide for a food product for boosting Antimicrobial Peptides (AMPs) in the intestinal epithelial cells of the gastrointestinal tract. It is another object of the present invention to provide a food product for inactivation or killing of enveloped viruses in the intestinal epithelial cells of the gastrointestinal tract.
It is a further object of the present invention to provide a food product for boosting Antimicrobial Peptides (AMPs) in the intestinal epithelial cells of the gastrointestinal tract thereby inactivating or killing enveloped viruses in the intestinal epithelial cells of the gastrointestinal tract.
The present inventors while working on this have surprisingly found that a food product that comprises an edible peroxisome proliferator-activated receptor (PPAR) fatty acid e.g. a hydroxy fatty acid; together with a vitamin B3 compound or its precursors or analogues thereof is able to synergistically boost AMP generation in the intestinal epithelial cells of the gastrointestinal tract and thereby protecting against viruses.
Edible PPAR fatty acid as per this invention includes edible fatty acids which have a PPAR action and also includes their corresponding mono, di and triglyceride forms.

It includes all foodstuffs, beverages, drinks and nutraceuticals that contains or consists of body nutrients, such as carbohydrates, fats, proteins, vitamins, minerals or similar ingredients which is ingested and assimilated to produce energy, stimulate growth and/or maintain life. When delivered as a nutraceutical it may be a vitamin/ mineral supplement in the form of a tablet, capsule, gummy or powder.
The present invention provides a food product comprising a vitamin B3 compound or its precursors or analogues thereof and an edible PPAR fatty acid preferably a hydroxy fatty acid having number of carbon atoms from 6 to 20
The most preferred vitamin B3 compound is niacinamide. This is also known as nicotinamide or as pyridine-3-carboxamide and is the active, water soluble form of vitamin B3. It is essential to the coenzymes NADH and NADPH and therefore for over 200 enzymatic reactions in the body including ATP formation.
Precursors of vitamin B3 compounds are also within the scope of the present invention. The most preferred precursor being tryptophan.
Analogues of vitamin B3 are also within the scope of the present invention. Nicotinamide, or pyridine 3- carboxamide has 2 other positional isomers by substitution at 2, and 4 position of the pyridine ring, picolinamide (pyridine 2- carboxamide) and iso-nicotinamide (pyridine 4- carboxamide) respectively. These two are the most preferred analogues. Analogues of vitamin B3, as per this invention, also includes derivatives like cyclo alkyl nicotinamide with the cyclo alkyl group having 3 to 6 carbon atoms.
The vitamin B3 compound or its precursors or analogues are preferably included in 0.01 to 1%, more preferably 0.02 to 0.6%, further more preferably 0.05 to 0.4% by total weight of the food product. The food composition of the present invention preferably comprises both the vitamin B3, its precursor or analogue thereof; and an edible PPAR fatty acid preferably a hydroxy fatty acid having number of carbon atom from 6 to 20.

Hydroxy fatty acids are derivatives of fatty acids containing a hydroxyl group at one or more positions. Preferably the fatty acids are saturated or unsaturated and branched or unbranched. The hydroxy fatty acids used in the present invention having 6 to 20 carbon atoms, preferably 8 to 20 carbon atoms, more preferably 10 to 16 carbon atoms, most preferably 10 to 14 carbon atoms. Hydroxy fatty acids as per this invention includes esters or precursors there. Esters may be of the C1-C6 alkyl esters. Precursors may be trihydroxy stearin or compounds that yield one or more molecules of hydroxystearic acid or hydroxystearate on their breakdown like mono, di or tri ester of glycerol with hydroxystearic acid.
Preferably the hydroxy fatty acid is selected from 2-hydroxymyristic acid, 3-hydroxymyristic acid, 2-hydroxypalmitic acid, 3-hydroxypalmitic acid, 10- hydroxystearic, 12-hydroxystearic acid, 17-hydroxystearic acid, trihydoxystearic acid (e.g. 9,10,13-trihydroxystearic acid) or trihydroxy stearin or compounds that yield one or more molecules of hydroxystearic acid or hydroxystearate on their breakdown like mono, di or tri ester of glycerol with hydroxystearic acid.
Preferably the hydroxy fatty acid is hydroxystearic acid. The most preferred hydroxystearic acids are 10 hydroxystearic acid (10HSA) and 12 hydroxystearic acid (12HSA).
