Don't panic, gluten free foods are readily available now in all the major supermarkets.
There is a much larger variety available now and it's virtually everywhere, with Tescos 'head and shoulders' above everyone else
According to the Coeliac Society Gluten Free food and Drink Directory:-
Tesco has a massive 1600 approx. GF products, up from 850 in 2007Sainsburys has about 1000 GF products, up from 550 in 2007
Marks & Spencers have about 650 products about the same or slightly less than 2007.
Waitrose have about 850 products up from about 600 in 2007
Boots have about 150 products up from about 100 last year
Somerfields have about 600 products, the same as last year
Asda have about 850 products up from 650 in 2007
Co-operative have about 450 products down from about 600 last year
This means that it really is much easier nowadays to cope with the needs of people who are wheat and gluten intolerant.
PS I checked out Tesco's in more detail:I did an analysis and Tesco's have 31 pages (up from 16 pages) of 'own label' goods all GF, - then there's the Free From Section (00's of products)
- then there's confectionery Cadbury's (a long list inc Roses), Bassetts, Beechs fine chocolates, Bendincks, Elizabeth Shaw, Green and Blacks, Nestle (Aero, After eight, Matchmakers, Polo, Quality Street,) Toblerone, Trebor, Wether's Original,
- then there's Sauces, Loyd Grossman, Meridian, Minara, Patak's, Sharwoods,Bertolli, Sacla, Knorr,and
- Desserts, 00's
- and Fish products John West, Glenryck
- and other major brands Heinz, McCain, Ross, Branston, Cottage Delight, Hellman's, Kraft, Leeora's, Golden Wonder, Walkers, Doritos, Baxters, and
- Stock Cubes, awt, Bisto, Bovril, Kallo, Knorr,
(For newcomers, this does NOT mean everything in their range(s) is gluten free but it does indicate that its much easier than you thought.)
