Some science behind the scenes
Sucrose
Sucrose, commonly named sugar or table sugar, is cane and beet sugar. Fructose, or fruit sugar, found in many plants, is often bonded to glucose to form sucrose. Sucrose is then a compound with one molecule of glucose covalently linked to one molecule of fructose.
A description of how fructose is processed by the digestive system is provided in Fructose and sucrose digestion.
Table sugar (sucrose) comes from plant sources. Two important sugar crops predominate: sugarcane (Saccharum spp.) and sugar beets (Beta vulgaris), in which sugar can account for 12% to 20% of the plant's dry weight. Minor commercial sugar crops include the date palm (Phoenix dactylifera), sorghum (Sorghum vulgare), and the sugar maple (Acer saccharum). Sucrose is obtained by extraction of these crops with hot water, concentration of the extract gives syrups, from which solid sucrose can be crystallized. In 2013, worldwide production of table sugar amounted to 175 million tonnes.
I have provided a list below from the USDA National nutrients database to provide more precise information on which foods it is found in. In the list that follows I have excluded a number of food types as the USDA database contains over 2000 products that include sugar. In general I have tried to exclude manufactured items, as most are only available in the USA and the food labelling normally tells you if sucrose is in the product anyway. Food types excluded which are known to contain sucrose, often in quite large amounts, include :
- breakfast cereals;
- ice cream - ice cream contains sugar
- meat stuffings - for all meats - turkey, chicken, pork, lamb etc
- baby foods - often contain sugar;
- catsups and other ketchups
- dips
- various mustards
- pickles – some sweet pickles – piccalilli for example
- chutneys - all chutneys contain sugars as this is what preserves them
- canned fruit, which is usually canned in fruit and sugar syrup
- soft drinks - colas, pops, ginger ale and other fizzy sweetened drinks;
- yoghurts - those containing fruit or those which are sweetened
- fast foods;
- ready meals - numerous ready meals contain sugars including salads such as coleslaw;
- restaurant foods;
- dehydrated or canned vegetables - sugars are added to act as preservatives
- frozen vegetables – freezing vegetables may cause degradation in the taste of the vegetable and then sugar may be added to ‘enhance’ their taste
- snacks - crisps/chips, pretzels etc;
- ready-made soups - tomato soup for example contains sugars
- sauces and gravies - which often contain a surprisingly large amount of sugar. Included in this is not just sweet sauces, which are an obvious source, but sauces such as horseradish sauce or the various tomato sauces for pasta;
- salad dressings, which again can often contain large amounts of sugars;
- sweets - which by definition contain sugars.
For those who think some cereals are 'healthy' it might be of interest to know that Kellogg's raisin bran [as an example] contains 12g of sugars for every 100g of cereal.
Foods with little or no sucrose
Dairy products - Simple unprocessed dairy products are sucrose free. Thus cheese - cheddar, cottage, cream, mozzarella, parmesan, queso, Neufchatel; cream – sour, cultured, ordinary; milk; yoghurt are all sucrose free. Some cream cheeses are sweetened, but cream cheese is normally without sucrose; something called ‘swiss cheese’ [which does not exist in Switzerland] is a processed cheese to which the American manufacturers add sugar.
It also appears the Americans have no access to milk - in other words milk from the cow. All their milk is processed with things taken out and things stuffed in - and the processing appears to add sugars to the milk.
Eggs – fresh unprocessed hen and duck eggs are sucrose free
Herbs – dried herbs in the USA appear to be processed using sucrose and are not sucrose free, but fresh basil, for example, is sucrose free and so are many other fresh herbs.
Fresh Spices – the USA appears to process its spices using sugar. The difference may be that the spices found are ground and grinding tends to cause more rapid deterioration in the spice. The sugar is possibly added to slow the process. Many whole spices appear to contain little if no sucrose.
Vinegars – cider vinegar and balsamic vinegar, although not fructose free, are sucrose free
Raw plain meat – Turkey, chicken, beef, pork, veal, duck, venison are all sucrose free. Some hams contain sucrose, some don’t, it depends on the curing process. There is one oddity in the USA where some turkeys appear to be being sugar coated or processed in sugar – perhaps for the holiday season. Natural turkey meat contains no sucrose [according to the tables]
Processed meat – In general processed meat contains a great deal of sucrose – hamburgers, chicken nuggets, luncheon meat and meatballs may all have added sugar. Ham may or may not contain sugar, it depends on the curing process. The same is true of bacon. Sausages are usually sugar free, though they may contain other preservatives. Salami is not sugar free.
But some processed meat - brockwirst, pepperoni, and pastrami is sucrose free, though it may not be fructose free.
Fruits – wild blueberries - commercially produced blueberries appear to have sucrose in them but wild blueberries don’t; avocados – this entry is very unclear in the USDA – seem to depend on the type of avocado, as avocados are listed as both having sucrose and not having sucrose; raw papayas and pomegranates have no sucrose, but do have fructose.
Beverages – most American beers do not contain sucrose, although they might contain other sugars and sweeteners, no European or Asian etc beers are listed. Tea, coffee and chocolate are sucrose free in their unadulterated ‘raw’ form, although fairly obviously chocolate bars and drinking chocolate are not sucrose free. Dry dessert wine is listed as being sucrose free, note that sweet dessert wine is not sucrose free. The sugars are converted into alcohol which is why these alcoholic beverages are sucrose free.
Seeds – seeds in general do not contain sucrose, even sprouting seeds like alfalfa. Seeds only contain sucrose if they have been processed, for example, roasted and then sprayed with sugars
Raw Vegetables – a number of raw vegetables have no sucrose – cauliflower, cucumber and lettuce [most sorts], for example. They may contain fructose. How much sugar a vegetable contains is dependent on how long it has been picked. New potatoes straight out of the ground are so sweet they are almost like a fruit. Baby, freshly picked carrots are much the same. The longer out of the ground a vegetable is, the more 'starchy' it becomes and thus measuring the sugar content of vegetables is fraught with problems. Most vegetables contain sugars. Onions, peas, carrots and sweetcorn contain more sugars in general than most.
Mushrooms – shiitake, chanterelle, morel, portabella, white, enoki, oyster, maitake, etc are sucrose free
Tomatoes – some canned varieties of tomatoes including tomato paste do contain sucrose, but a number of tomato products do not, according to the tables, although they will contain fructose, for example:
- Tomatoes, red, ripe, raw
- Tomatoes, red, ripe, cooked
- Tomatoes, red, ripe, canned, packed in tomato juice
- Tomato juice, canned, with salt added but no sugar
- Tomato products, canned, puree, without salt or sugar added
Peppers – there appears to be some confusing information regarding peppers. Raw green peppers are listed in both the section of those foods containing sucrose and the section of those containing no sucrose. Sweet red raw red peppers are according to the USDA sucrose free, as are raw jalapeno peppers
Pickles – a number of pickles are listed as having no sucrose including cucumber, dill, and kosher dill, but they may have fructose
Raw fish and shellfish – all raw, unprocessed fish and shellfish is sucrose free including flatfish, salmon, crab, lobster, shrimp, prawn, clam, oyster, scallop and so on. This is not true of processed fish including fish fingers
Soy products – Miso and soy sauce are sucrose free
Bakery products – The vast majority of bakery products contain sucrose – sugar – for example many pastries, crackers, 'cookies', biscuits, pancakes, bagels, pies, muffins, rolls, sponges, cakes and some sweet breads often contain fructose and sucrose; even tacos, rolls and pizzas can contain sugar.
But a very small number of breads and crackers are sucrose free, although they may not be fructose free – care is needed here. Naan bread, for example, appears to be sucrose free from the charts; some [not all] tortillas appear to be sucrose free
Sweeteners – the natural sugar syrup from agaves is sucrose free
Rice – it appears that American manufacturers parboil, boil or process a considerable amount of the rice for the American market – both long grain and not, both wholegrain and not. This processed rice often contains added sucrose. Wild rice is not actually a rice, but a sort of grass and contains sucrose, this can be seen from the table.
There is confusing evidence as regards brown rice. It appears that the bran in brown rice does contain sucrose and thus even raw unprocessed brown rice contains sucrose. In contrast, white rice whether long grain or short grain, because it has been stripped of its bran is sucrose free
Pasta - the majority of pasta, including noodles, contains no sucrose. In the USA it appears manufacturers do add sugar to pasta, particularly macaroni and spaghetti, a process which does not seem to take place in Europe.
Nuts - the majority of simple plain unprocessed nuts, blanched or with their skins on, contain no sugar or only trace amounts. The exceptions appear to be pistachio nuts, cashew nuts, almonds, hazelnuts, pecans, pine nuts and macademia nuts. But the problems with the USDA tables are that it is very unclear whether these have been processed or not. Dry roasting adds sugar, frying appears to be a process involving sugar. Some of the nut butters have added sugar. But a nut can appear in the list of products with no sugar and with sugar, as such it is clearly a processing issue and the overall information is very unclear, in this instant you have to read the packet labelling.
Foods with sugars - sucrose
As you can see from the following chart sucrose can be found in table sugar, honey, molasses and maple syrup, as well as fruit and some vegetable fruits. Dried fruit contains more sugars per gram than fresh fruits.
Smoothies, though not listed are thus a source of considerable amount of sucrose and fructose.
