Expert advice to help you maintain a healthy weight

Dissatisfied with your weight?
We're bombarded with scare stories about weight, from size zero to the obesity 'epidemic'. But a healthy weight is determined by different factors for each of us. Our expert advice is designed to help you achieve and maintain a healthy, life-enhancing weight.

Overweight or underweight?
Being the right weight has a positive effect on wellbeing but also on our health, as being the wrong weight can cause a range of medical problems.

Many popular drinks contain the stimulant caffeine. It has a bad reputation, but what effects does it really have and does it bring any health benefits?

Effects of caffeine
Caffeine acts as a stimulant to the heart and central nervous system, and is also known to increase blood pressure in the short term, although there's no conclusive evidence of long-term effects on blood pressure.

The effects on blood pressure are most likely when caffeine is taken in excessive quantities or by people who are highly sensitive to it. People who are hypertensive (have habitual high blood pressure) are advised to avoid caffeinated drinks, and pregnant women should limit their intake of caffeine to less than 300mg a day.

Food Caffeine content
Coffee (mg/cup)
Instant 61 to 70
Percolated ground 97 to 125
Tea (mg/cup) 15 to 75
Cocoa (mg/cup) 10 to 17
Chocolate bar 60 to 70
Cola drinks 43 to 65
(mg/12oz can)

Caffeine and weight loss
Caffeine has been shown to have very modest effects on increasing metabolism, and is sometimes added as an ingredient to weight loss pills. These pills often make claims about speeding metabolism to 'effortlessly melt' excess fat, but in reality the amount of calories that slimming pills containing caffeine would actually burn is very small.

Caffeine may also suppress appetite, but without making other changes to your diet and lifestyle caffeine is unlikely to make a significant difference to your weight.

Coffee
Coffee has been linked with a number of the risk factors for coronary heart disease, including increased blood pressure and raised blood cholesterol levels. But no relationship has been found between drinking coffee and the likelihood of developing coronary heart disease.

Coffee may be beneficial in some areas of health - for example, research has found it may reduce the risk of developing gallstones and kidney stones.

It's difficult to suggest a safe limit for coffee intake because of the huge variation in caffeine content across different brands and an individual's sensitivity to the drug. People with high blood pressure and pregnant women are advised to limit their caffeine consumption.

For the rest of the population, there's no evidence coffee does any long-term harm. Caffeine does have a very mild diuretic effect but, drunk in moderation, you don’t need to increase fluid intake to any significant degree as the loss of fluid is very minimal.

Tea
Tea contains some useful minerals such as zinc, manganese and potassium, and scientists are researching its potential to reduce the risk of coronary heart disease and some cancers.

Tea contains antioxidant substances called flavonoids, which have been shown to help slow or inhibit the chemical reactions thought to take place during the development of coronary heart disease.

Green tea
There's also a lot of interest in the health benefits of green tea, particularly in relation to cardiovascular health. Again, this is due to flavonoids, which are powerful antioxidants found in high concentrations in both green and black teas. The concentration of these compounds depends on how long the tea has been brewed, but can range from 125mg to 140mg.

Some studies have compared the concentration of these antioxidant compounds to that found in fruit and vegetables. Flavonoids bring potential benefits to heart health, as well as possible reductions in the risk of Alzheimer’s disease and other neurodegenerative conditions.

Caffeine and iron absorption
Both tea and coffee contain polyphenols that can bind to iron, making it difficult for our bodies to absorb. Avoiding tea and coffee during and around mealtimes is important for people at risk of iron deficiency.

The Digestive System

Expert advice to help you maintain a healthy weight

Dissatisfied with your weight?
We're bombarded with scare stories about weight, from size zero to the obesity 'epidemic'. But a healthy weight is determined by different factors for each of us. Our expert advice is designed to help you achieve and maintain a healthy, life-enhancing weight.

Overweight or underweight?
Being the right weight has a positive effect on wellbeing but also on our health, as being the wrong weight can cause a range of medical problems.

When you eat, the food's journey through the body is governed by the digestive system.

What is digestion?
Digestion is the process of breaking down food so that it's small enough to be absorbed and used by the body for energy or in other bodily functions.

Digestion involves a number of different stages. The first phase is known as the cephalic (head) phase. It starts before food has even entered your mouth. The sight, smell, taste or even the thought of food will activate saliva in the mouth as well as digestive juices, which contain enzymes to break down food.

In the mouth
Once food is in the mouth, the tastebuds begin determining the chemicals within the food via their nerve endings, in order to give you the taste sensations of salt, sweet, sour or bitter. As your teeth chew and grind the food, breaking it down, it's mixed with saliva. This comprises many enzymes including salivary amylase, which begins to break down the long chains of starch found in foods such as bread, cereals, potatoes and pasta. Saliva also contains mucin, which moistens the food so it can pass easily through the digestive (gastrointestinal) tract.

The oesophagus
After the food has been swallowed, it's carried down the oesophagus (a muscular tube) towards the stomach. The oesophagus can contract and relax in order to propel the food onwards, and each mouthful of food takes about six seconds to reach the stomach once swallowed.

The stomach
The stomach is a sack made of muscle and, when it's empty, it has a volume of only 50ml but this can expand to hold up to 1.5 litres or more after a meal. The walls of the stomach are made of three different layers of muscle that allow it to churn food around and make sure it's mixed with the stomach's acidic digestive juices. The presence of hydrochloric acid in the stomach prevents the action of salivary amylase and helps to kill bacteria that might be present. The stomach also produces the enzyme pepsin, which breaks down proteins (mostly found in meat, fish, eggs and dairy products).

The hormone ghrelin is produced by cells lining the stomach. Ghrelin stimulates hunger and tends to increase before a meal and decrease after eating. This hormone forms part of the communication system between the gut and the part of the brain that controls hunger and satiety (how full you feel).

Food can stay in the stomach for a few minutes or several hours in the gastric phase where numerous acids and enzymes are released, including the hormone gastrin. When the food has been churned into a creamy mixture known as chyme, the pyloric sphincter (an opening controlled by muscle) opens and chyme passes gradually into the small intestine.

Prebiotics
These are mainly indigestible carbohydrates called oligosaccharides. On reaching the large intestine, they selectively stimulate the growth and/or activity of beneficial microorganisms already in the colon, such as bifidobacteria and lactobacilli.

The small intestine
About 3ml of chyme is squirted into the small intestine at short intervals as the pyloric sphincter opens. This is known as the intestinal phase and causes the secretion of many hormones, which all aid the digestive process. The sphincter is designed to open partially so that large particles are kept in the stomach for further mixing and breaking down.

Digestion and absorption of fats, protein and carbohydrates occurs in the small intestine. Three important organs are involved:

The gall bladder provides bile salts that help to make fats easier to absorb.
The pancreas provides bicarbonate to neutralise the acidic chyme from the stomach, and also produces further digestive enzymes.

The intestinal wall contains cells that make up the wall of the small intestine. These cells help to neutralise the acid and also produce enzymes to digest food.

The inner surface of the small intestine is folded into finger-like structures called villi, which greatly increase the surface area available for absorption - in fact the surface area of the villi is equivalent to that of a tennis court! Blood vessels receive the digested food from the villi where it's then transported through the blood stream to the liver via the hepatic portal vein.

Fat can take much longer to be broken down, with the process of fat digestion and absorption taking between three and five hours.

The unabsorbed residue of this process finally reaches the end of the small intestine and enters the large intestine.

Probiotics
Probiotics are live bacteria similar to the bacterial micro-organisms that live in the large intestine. They are often referred to as 'friendly bacteria', and come from food sources or dietary supplements. The mix of these 'friendly' bacteria and other gut microorganisms is important for good health, and many factors can alter this delicate balance, such as infection or use of antibiotics. Friendly bacteria are vital for proper development of the immune system, to protect against micro-organisms that could cause disease, and to aid the digestion and absorption of food and nutrients.

The large intestine
This is one of the most metabolically active organs in the body. It measures about 1.5 metres and contains over 400 different species of bacteria that break down and utilise the undigested residues of our food, mostly dietary fibres. As the watery contents move along the large intestine, water is absorbed and the final product - faeces - is formed, which is stored in the rectum before excretion from the body.

Attention Deficit Hyperactivity Disorder

Definition
ADHD is a problem with inattentiveness, over-activity, impulsivity, or some combination of these. For these problems to be diagnosed as ADHD, they must be out of the normal range for the child's age and development.

Overview, Causes, & Risk Factors

Is ADHD over-diagnosed? Under-diagnosed? Probably both -- and certainly real. ADHD affects children's school performance and their relationships with others. Parents who are wondering if their children have ADHD are often exhausted and frustrated.

Scientific studies, using advanced neuroimaging techniques of brain structure and function, show that the brains of children with ADHD are different from those of other children. These children handle neurotransmitters (including dopamine, serotonin, and adrenalin) differently from their peers.

ADHD is often genetic. Whatever the specific cause may be, it seems to be set in motion very early in life as the brain is developing. Other problems, such as depression, sleep deprivation, specific learning disabilities, tic disorders, and oppositional/aggressive behavior problems, may be confused with or appear along with ADHD. Every child suspected of having ADHD deserves a careful evaluation to sort out exactly what is contributing to his concerning behaviors.

Attention Deficit Disorder (ADD) is the most commonly diagnosed behavioral disorder of childhood, affecting an estimated 3 - 5% of school aged children. It is diagnosed much more often in boys than in girls.

Most children with ADHD also have at least one other developmental or behavioral problem. Every evaluation should include a search for possible additional conditions, including conduct disorder, oppositional defiant disorder, mood disorders, depression, anxiety, and learning disabilities.

Multiple Sclerosis or MS

Multiple sclerosis (abbreviated MS, also known as disseminated sclerosis or encephalomyelitis disseminata) is an autoimmune condition in which the immune system attacks the central nervous system, leading to demyelination. Disease onset usually occurs in young adults, and it is more common in women. It has a prevalence that ranges between 2 and 150 per 100,000. MS was first described in 1868 by Jean-Martin Charcot.

MS affects the areas of the brain and spinal cord known as the white matter, destroying a fatty layer called the myelin sheath, which wraps around nerve fibers and electrically insulates them. When myelin is lost, the axons of neurons can no longer effectively conduct action potentials. The name multiple sclerosis refers to the scars (scleroses – better known as plaques or lesions) in the white matter. Although much is known about the mechanisms involved in the disease process, the cause remains unknown. Theories include genetics or infections. Different environmental risk factors have also been found.

Almost any neurological symptom can appear with the disease, and often progresses to physical and cognitive disability. MS takes several forms, with new symptoms occurring either in discrete attacks (relapsing forms) or slowly accumulating over time (progressive forms). Between attacks, symptoms may go away completely, but permanent neurological problems often occur, especially as the disease advances.

There is no known cure for MS. Treatments attempt to return function after an attack, prevent new attacks, and prevent disability. MS medications can have adverse effects or be poorly tolerated, and many patients pursue alternative treatments, despite the lack of supporting scientific study. The prognosis is difficult to predict, it depends on the subtype of the disease, the individual patient’s disease characteristics, the initial symptoms and the degree of disability the person experiences as time advances. Life expectancy of patients is nearly the same as that of the unaffected population.

Importance Of Water Fluid

Dissatisfied with your weight?
We're bombarded with scare stories about weight, from size zero to the obesity 'epidemic'. But a healthy weight is determined by different factors for each of us. Our expert advice is designed to help you achieve and maintain a healthy, life-enhancing weight.

Overweight or underweight?
Being the right weight has a positive effect on wellbeing but also on our health, as being the wrong weight can cause a range of medical problems.


Water or fluid is a vital component of our diets, even though it's not considered a specific nutrient.

Why do we need water?
Water makes up 50 to 70 per cent of an adult's total body weight and, without regular top-ups, our body's survival time is limited to a matter of days.

Water's essential for the body's growth and maintenance, as it's involved in a number of processes. For example, it helps get rid of waste and regulates temperature, and it provides a medium for biological reactions to occur in the body.

Water's lost from the body through urine and sweat, and must be replaced through the diet. If you don't consume enough you can become dehydrated, causing symptoms such as headaches, tiredness and loss of concentration. Chronic dehydration can contribute to a number of health problems such as constipation and kidney stones.

How much do we need?
The body gets its fluid from three sources:

Drinks, either plain water or as part of other beverages including tea, coffee and squash
Solid foods, especially fruit and vegetables (even foods such as bread and cheese provide small amounts of fluid)
As a by-product of chemical reactions within the body

Most healthy adults need between one and a half to three litres a day, so aim to drink six to eight medium glasses of fluid daily. Beverages such as tea, coffee and fruit juices count towards fluid intake, and may bring with them other nutrients or benefits.

You may require more fluid if you're very physically active or during periods of hot weather.

You can judge whether you're drinking enough by the colour of your urine. If it's a pale straw colour then your fluid intake is probably fine. If your urine is dark yellow, you probably need to drink more.

How to maintain fluid levels

Start as you mean to go on, with a glass of water when you wake.
Find time to make yourself regular drinks during the day - don't forget that tea, coffee and juices can count. Just watch out for the amount of sugar consumed in some soft drinks.
Keep a bottle of water in your bag, as it's a convenient way of providing fluid if you're travelling or exercising.
Get into the habit of having a glass of water with every meal.
The sensation of thirst is not triggered until you're already dehydrated, so it's important to drink before you get thirsty.
Increase your intake of fresh fruit and vegetables, as they have a high water content.
Bottled water
There are two types: spring water and mineral water.

Spring water is collected directly from the spring where it rises from the ground, and must be bottled at the source. UK sources of spring water must meet certain hygiene standards, and may be further treated so they meet pollution regulations.

Mineral water emerges from under the ground, then flows over rocks before it's collected, resulting in a higher content of various minerals. Unlike spring water, it can't be treated except to remove grit and dirt. Different brands of spring and mineral waters have differing amounts of minerals depending on their source.

Is it necessary to buy bottled water?
The drinking water available from UK taps is perfectly adequate to replenish fluid loss, and undergoes many processes to bring it up to the standards set out in the UK Water Supply Regulations.

In some areas tap water has fluoride added, which can reduce the risk of dental decay.

There are certainly no proven health benefits of bottled water over tap water. Although there are growing concerns about the sustainability of bottled water, ultimately it comes down to personal choice.

Bread, Cereals and Other Starchy Foods

This food group is your body's main source of energy and contains bread, pasta, rice, potatoes, noodles, chapatti, cereals and other starchy carbohydrates.

Refined and unrefined grains
The foods listed above (apart from potatoes) are all produced from grains, such as wheat, corn or rice. They should be a part of all meals, filling about a third of your plate. They can come in two forms – refined or unrefined (often known as whole grains).

Refined grains have been stripped of their outer bran coating and inner germ during the milling process, leaving only the endosperm. They include white rice, white bread and white pasta.

In a whole grain the bran, germ and endosperm are all still present. The bran is an excellent source of fibre; the germ is a source of protein, vitamins and minerals; and the endosperm supplies most of the carbohydrates, mainly in the form of starch. Unrefined or whole grain forms provide far more nutrients than their unrefined counterparts.

Whole grains are rich in phytochemicals and antioxidants, which help to protect against coronary heart disease, certain cancers, and diabetes. Studies have shown people who eat more whole grains tend to have a healthier heart.

Most people get their whole grain from wholemeal bread or whole grain breakfast cereals such as porridge, muesli or whole wheat cereals. Choose a whole grain variety over processed or refined grains, and look out for added sugar or salt.

Other whole grains include:

Wheat
Oats
Maize
Barley
Rye
Millet
Quinoa
Wild rice

Fibre
Dietary fibre is found in plant foods (fruit, vegetables and whole grains) and is essential for maintaining a healthy digestive system. Fibre cannot be fully digested and is often called bulk or roughage. The two types of fibre found in food are soluble and insoluble.

Soluble fibre, which can dissolve in water, is found in beans, fruit and oat products, and can help to lower blood fats and maintain blood sugar.

Insoluble fibre cannot dissolve in water, so passes directly through the digestive system. It’s found in whole grain products and vegetables and it increases the rate at which food passes through the gut.

Evidence for health benefits of fibre
High-fibre foods take longer to digest, so keep you feeling fuller for longer. The slow and steady digestion of food through the gut helps control blood sugar and assists with weight maintenance
Fibre helps in the digestive process and can help lower blood cholesterol
Fibre promotes bowel regularity and keeping the gastrointestinal tract clean to help reduce the risk of developing diverticular disease and constipation
A high-fibre diet may reduce the risk of developing diabetes and colorectal cancer

To eat more fibre, try these healthy swaps:

Refined Swap Unrefined
Frosted flakes Bran flakes
White toast Porridge oats
Cereal bar Rice cakes
French bread Wholemeal bread
Normal pasta Wholewheat pasta
Breadstick Dark rye crispbread


How much is enough?
Bread, rice, potatoes, pasta and other starchy foods should make up about one third of your diet. Try these recipes from the BBC Food website:

Banana and Oat Smoothie
Wholemeal pizza baguettes
Ham and watercress sandwich on wholemeal bread
Creamy lentils and brown rice
Using wholemeal flour in baking, as in this Irish Soda Bread or half and half as in these Carrot and Pineapple Muffins

What about GI?
The glycaemic index (GI) is a way of ranking carbohydrate foods based on how quickly they increase blood sugar levels. Low GI foods are especially helpful for people with diabetes, who need to have more control over their blood sugar levels than the general population.

Ideally foods with a low GI, such as those rich in soluble fibre like oats and legumes, should be eaten more frequently than those with a high GI. But the texture, type of cooking or processing used, and the amount and type of sugars present can all affect the GI. Since foods are often consumed as part of a meal or snack, it can be difficult to calculate the GI. Focusing on unrefined, high-fibre, whole grain cereals and minimising rapidly absorbed, refined cereals and sugary foods will all help to lower the GI of your diet.

Importance Of Salt

Salt, also known as sodium chloride, is made up of 40 per cent sodium and 60 per cent chloride. Found predominantly in pre-prepared foods, excessive salt consumption has been linked with high blood pressure and stomach cancer, and can exacerbate osteoporosis and asthma.

Why is it needed?
The sodium component of salt is vital for controlling the amount of water in the body, maintaining the normal pH of blood, transmitting nerve signals and helping muscular contraction. Salt is present in all foods in varying degrees, and almost all processed foods contain added salt.

Daily requirements
Sodium, unlike all other minerals, is generally overconsumed, with the dietary intake of salt in the UK being far in excess of the recommended daily requirement.

Adults are advised to consume no more than 6g salt per day (about one teaspoon). Current intake is about 9g per day – a third higher than is recommended for good health. Babies and children should have less salt than adults. High salt intake in babies can be especially dangerous, as their kidneys cannot cope with large amounts. Recommendations for babies and children are given below:


Age (years) Salt (g/day)
1 to 3 2 (0.8g sodium)
4 to 6 3 (1.2g sodium)
7 to 10 5 (2g sodium)
11 plus 6 (2.4g sodium)


Reducing salt intake
The government has set a target of reducing the average salt consumption of adults to 6g per day by 2010. This is a challenging but achievable goal, which will bring measurable improvements in health. A study published in the scientific journal Hypertension in 2003 estimated that a reduction in salt intake to 6g per day would lead to a 13 per cent reduction in stroke and a 10 per cent reduction in ischaemic heart disease.

People who have experienced heart problems or have high blood pressure should follow a low-salt diet and take advice from their health care professional. Reducing sodium has been proven to be one of the best ways of lowering high blood pressure, especially in combination with broader dietary changes.

Choosing Healthier Options

Overweight or underweight?
Being the right weight has a positive effect on wellbeing but also on our health, as being the wrong weight can cause a range of medical problems.

More and more of us are eating out on a regular basis, whether it's for a business lunch, a girls' get together, or for a family meal.

The 2006 Family Food Survey found that households where the head of the household was under 30 years old were spending more than 40 per cent of their food budget on eating out.

Eating out usually means that we have little control over how the food is prepared or how large the portion is. Foods eaten out tend to be higher in fat and research has shown that those who eat out regularly generally have higher intakes of fat, salt and calories. Studies have also shown that eating with friends can tempt us to overeat. Meals with multiple courses eaten over longer periods and with alcohol are all associated with overindulgence. Large serving bowls and spoons increase the likelihood of piling more food on your plate than you usually eat.

Unlike packaged food, foods bought from cafes, restaurants etc don't have to carry nutritional information and so opting for the healthiest option might not always be obvious, or easy. However, with some knowledge and thought, eating out can be enjoyable and healthy!

General tips
If you're unsure as to what something is, or what it contains - ask! If the waiter/waitress doesn't know, then the chef will.
Think ahead, if you know you're eating out later and it could be a lavish affair, choose wisely earlier in the day to keep calories, fat, sugar and salt intakes under control.
Don't eat an extra course just to be polite.
Only order a sweet after the main course, and only if still hungry. Opt for sorbets, or fruit dishes to balance out a heavy main course.
Think about sharing a course with a companion if the portions look large.
Speak up about how you'd like a dish prepared eg ask for no mayonnaise, dressing on the side.
You're more likely to overeat at an 'all you can eat' style buffet.
Choose side orders of salad or vegetables to fill up on.
Cut off any visible fat from meat to keep saturated fat intake down.
Look out for smaller portions ie a main meal option as a starter size.
Opt for dishes which are grilled, baked, steamed, poached or cooked in own juice rather than fried.
Check the menu for dressings on salads and ask for it to be served separately. An otherwise healthy and nutritious salad could be drowned in a high fat sauce, bumping up its calorie content.
Avoid cheese, cream or butter-based sauces
If you're a cheese lover, think about sharing the cheese board option to keep saturated fat, salt and calorie intakes in check.

Fats and Sugar

These foods, although an important energy source, often contain few other nutrients, so it's healthier to limit their consumption.

What are they?
This group, which includes foods such as cakes, biscuits, sweets, sugar-sweetened drinks and crisps, makes up the smallest section of the Food Standards Agency's 'eatwell plate'.

Fat facts
Fat transports the fat-soluble vitamins A, D, E and K around the body
It can often improve the flavour and perception of foods, increasing their palatability
It supplies essential nutrients such as fat-soluble vitamins and essential fatty acids (EFAs)
EFAs must be supplied from the diet, and are thought to have a positive effect on heart health and the immune system
It has a key role in membrane structure
It cushions, and so protects, the internal organs
It's stored in adipose tissue (a thick layer of tissue under the skin) as a long-term fuel reserve. Excess fat may also accumulate around your organs, especially in the abdominal cavity

Fat is a concentrated source of energy. Just 1g provides nine calories - more than double the calories in 1g of protein or carbohydrate.

This means it's much easier to consume too many calories when eating high-fat foods. People trying to manage their weight should reduce fatty foods to help cut calories. We all need some fat in our diets, but small quantities of EFAs are the key to good health.

The two types of fat
Fat can be divided into two main groups - saturated and unsaturated.

Saturated fat is generally solid at room temperature and is usually from animal sources. It's found in lard, butter, hard margarine, cheese, whole milk and anything that contains these ingredients, such as cakes, chocolate, biscuits, pies and pastries. It's also the white fat you can see on red meat and underneath poultry skin.

How much saturated fat you eat is associated with increased blood cholesterol concentrations and an increased risk of heart disease. Eating less helps to minimise the risks it poses to heart health.

Unsaturated fat is usually liquid at room temperature and generally comes from vegetable sources. Monounsaturated and polyunsaturated fats are both included in this group.

Unsaturated vegetable oils are a healthier alternative to saturated fat and can be found in sesame, sunflower, soya and olive oil, soft margarine and in foods such as oily fish, including mackerel, sardines, pilchards and salmon. Where possible, you should ensure the fat you eat is unsaturated.

Did you know...?

A jam doughnut contains 10.9g fat
A slice of malt loaf contains 0.7g fat
A teaspoon of peanut butter contains 5.4g fat
A pint of whole milk contains 22.8 g fat
A handful of mixed nuts contains 21.6g fat

How much is enough?
Government guidelines recommend fats make up no more than 35 per cent of the energy in your diet, and that saturated fats should provide less than 11 per cent of total energy intake.

For the average woman, this means about 70g of total fat a day; for men, roughly 95g.

The latest National Diet and Nutrition Survey showed that, on average, UK adults consume about the right amount of fat, but that the intake of saturated fats is currently too high for good health (at present they provide about 13 per cent of total energy).

To reduce the amount of fat in your diet, try the following:

Look for alternatives to cakes, biscuits and savoury snacks, which are often high in fat - try fresh fruit, dried fruit and cereal-based products
Trim any visible fat off meat and poultry
Buy lean cuts of meat and reduced-fat minces
Poach, steam, grill or bake food rather than fry it
Swap whole milk for semi-skimmed or skimmed
Opt for low-fat dairy products
If you use lard, butter or hard margarine, switch to vegetable oil and low-fat spreads

Sugary foods
There are two types of sugar - those found naturally in fruit and milk (which are fine and don't need to be cut down) and those that are added to the diet.

These added sugars can be found in a variety of foods including confectionery, soft drinks, desserts and breakfast cereals. Added sugars are a great source of energy, but provide no other nutrients.

Sugary foods and drinks pose a threat to dental health, especially if consumed between meals.

Even the sugars in honey and fruit juices can cause tooth decay if good oral hygiene isn't followed and you consume a lot of these foods.

Only have sugary foods at mealtimes, when other dietary and oral factors can help to minimise the risk they pose to your teeth.

Sugary drinks have been identified as a possible cause of obesity. These drinks do not trigger the same sense of fullness as food with similar calories, increasing the risk of overeating.

How to reduce consumption of sugary foods
Swap sugary drinks for water, low-fat milk or artificially sweetened drinks to reduce your calorie intake
Try swapping sugary snacks for fruit or bread-based options such as fresh whole fruit or teacakes/malt loaf
Try to halve the amount of sugar you put in hot drinks, or cut it out completely
Buy reduced-sugar varieties of jam and marmalade
Choose tinned fruit in natural juice rather than syrup
