A digestive biscuit, sometimes described as a sweet-meal biscuit, is a semi-sweet biscuit that originated in Scotland, and is popular worldwide. The digestive was first developed in 1839 by two Scottish doctors to aid digestion. The term "digestive" is derived from the belief that they had antacid properties due to the use of sodium bicarbonate when they were first developed. Historically, some producers used diastatic malt extract to "digest" some of the starch that existed in flour prior to baking.

First manufactured in 1892, McVitie's digestive is the best-selling biscuit in the UK. The digestive is ranked the fourth most popular biscuit for "dunking" into tea among the British public, with the chocolate digestive coming in at number one.
In 1839, digestives were first developed in the United Kingdom by two Scottish doctors to aid digestion. Digestives featured in advertisements for the Berkshire-based biscuit company Huntley & Palmers in 1876, with a recipe being given in Cassell's "New Universal Cookery Book" of 1894. In 1851 an issue of The Lancet London's advertising section offered brown meal digestive biscuits. At the time, it was asserted grain millers knew only of bran and endosperm. After 10% of the whole grain's coarser outer-bran coat was removed, and because the innermost 70% of pure endosperm was reserved for other uses, brown meal, representing only 20% of the whole grain, remained, consisting of about 15% fine bran and 85% white flour. By 1912 it was more widely known that brown meal included the germ, which lent a characteristic sweetness.
In 1889, John Montgomerie of Scotland filed a U.S. patent application, which was granted in 1890. This patent asserted a prior patent existed in England dated 1886. The U.S. patent, titled "Making Malted Bread", included instructions for the manufacture of digestive biscuits. Montgomerie claimed this saccharification process would make "nourishing food for people of weak digestion".
Despite rumours that it is illegal for them to be sold under their usual name in the United States, they are, in fact, widely available in imported food sections of grocery stores and by mail order.
The typical digestive biscuit contains coarse brown wheat flour (which gives it its distinctive texture and flavour), sugar, malt extract, vegetable oil, wholemeal, raising agents (usually sodium bicarbonate, tartaric acid and malic acid) and salt. Dried whey, oatmeal, cultured skimmed milk and emulsifiers such as DATEM may also be added in some varieties.
A digestive biscuit averages around 70 calories, although this sometimes varies according to the factors involved in its production.
Digestive biscuits are frequently eaten with tea or coffee. Sometimes, the biscuit is dunked into the tea and eaten quickly due to the biscuit's tendency to disintegrate when wet. Digestive biscuits are one of the top 10 biscuits in the United Kingdom for dunking in tea. The digestive biscuit is also used as a cracker with cheeses, and is often included in "cracker selection" packets.
In the UK, McVitie's digestive is the best selling biscuit, with 80 million packs sold annually. Digestives are also popular in food preparation for making into bases for cheesecakes and similar desserts.
Digestive biscuits are also available, coated on the underside with milk, dark or white chocolate. Originally produced by McVitie's in 1925 in the UK as the Chocolate Homewheat Digestive, other varieties include the basic biscuit with chocolate shavings throughout (chocolate "chips" in the biscuit mix), or a layer of caramel, mint chocolate, orange-flavoured chocolate, or plain chocolate. American travel writer Bill Bryson described the chocolate digestive as "a British masterpiece". The McVitie's chocolate digestive is the most popular biscuit in the UK to dunk into tea.
In pop cultureEdit
McVitie's digestive biscuits have become known among fans of the rock group The Beatles because they were the cause of an argument between George Harrison and John Lennon during a recording session for the group's 1969 album Abbey Road. The incident was recounted by recording engineer Geoff Emerick in his book Here, There, and Everywhere: My Life Recording the Music of The Beatles. According to Emerick, Lennon's wife Yoko Ono was in the recording studio and at one point helped herself to Harrison's box of McVitie's while the Beatles were in the control room listening to a playback of the song they'd just recorded. Harrison got angry at Ono, and his subsequent outburst caused Lennon to lose his temper in response.
Chocolate digestives were the technical challenge to the bakers in series 3, episode 8 of The Great British Bake Off. They were also the technical challenge to the bakers in episode 2, season 2 of The Great Canadian Baking Show.
In the ITV television show "Doc Martin" the character Louisa Glasson (played by Caroline Catz) likes to eat Chocolate Digestives. Her boyfriend/husband Martin Ellingham (played by Martin Clunes) tries to stop her behavior.

Digestive biscuits are prepared in such a manner that they may contain diastase, the nitrogenous transforming matter of malt; but whatever quantity of this substance they may contain in the condition of dough is destroyed in the process of baking.

A new competitor in this field was Paterson's Extract of Malt, exhibited by the Phoenix Chemical Works, Glasgow; the odour and flavour of this was excellent, and it is said to be rich in diastasic power. Prepared from it was exhibited a series of digestive biscuits, rusks and bread by John Montgomerie, of Glasgow. In making these part of the starch of the flour is changed by being mixed with the malt extract and water and kept for some time at a suitable temperature; the yeast being probably added to another portion of flour and water, to form dough to mix with the above before baking. These biscuits seemed to be appreciated by visitors. Messrs. Hill and Son also exhibited some malted nursery biscuits. Benger's well known digestive ferments were well displayed, together with an essence of rennet recently introduced.

Professor Johnston remarks that -- "The grain of wheat consists of two parts, with which the miller is familiar -- the inner grain and the skin that covers it. The inner grain gives the pure wheat flour; the skin when separated, forms the bran."

The Parisian white bread is prepared with the finest flour (1re marque), which does not contain any bran. If 100 parts wheat yield 70 parts of this flour, the remainder will consist of 10 parts bran and 20 parts coarse brown meal, this latter consisting of 3 parts fine bran and 17 parts white flour.

By allowing the germ and all but the outer, coarser layers of broad bran to mix in with the flour, we get the sweet-tasting brown meal producing the brown bread so much in favour amongst sections of the community.
