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.

Infants birth to six months
Making the right choices when it comes to feeding new babies will help them get a good start in life. BreastfeedingThe Department of Health recommends that, wherever possible, infants are breastfed exclusively until six months of age.Breastmilk is the best source of nutrition for newborn babies, as it provides easily digestible nutrients in the right quantities. It's also packed with antibodies and helps to establish the baby's immune system.Babies breastfed exclusively are reported to be at less risk of stomach upsets and ear, respiratory and urinary tract infections than those who are bottle-fed formula milk. They're also less likely to become obese or experience constipation and vomiting. If there's a family history of allergies or diabetes, breastfed babies are less likely to develop these.Breastmilk contains substances that help the development of a baby's brain, retinas, gut lining and protective sheath for the central nervous system. Breastmilk also contains hormonal factors that help the baby's growth and development. It carries digestive enzymes, too, which help to digest the nutrients in milk, helping the baby's immature digestive tract.When not to breastfeedBreastfeeding isn't recommended for all women. For example, those who are HIV-positive risk transmitting the disease to their baby through their milk. If you're taking any medication, you should also check with your doctor or midwife before breastfeeding.Types of breastmilkDuring the first few days after birth, the mother's breasts produce a substance called colostrum. This yellowish fluid is packed with antibodies and is rich in protein, making it ideal for newborn babies. The colostrum soon changes and becomes thin and white (transitional milk). Then, after three or four days, the mature breastmilk starts to come through. At each feed the breasts produce two types of milk: foremilk, produced at the beginning of a feed; and hindmilk, which has more fat, energy and essential nutrients. As babies grow, it's important they receive the hindmilk in order to meet their nutritional needs.

Maintaining health as we age can be challenging, so a diet rich in nutrients is increasingly important as we grow older. Factors that affect nutritionThere are many factors that influence nutritional status in older adults, and they can be broadly grouped into four main areas: Those that naturally occur during the ageing process, such as a reduced ability to absorb nutrients efficiently, or a sore mouth due to denturesDisease-specific conditions such as cancer, which place greater nutritional demands on people Some drugs that interact with nutrients and prevent absorption, for example aspirin, which can interfere with the absorption of vitamin CSocial influences, such as not being able to get to shops, or social isolationContinuing to enjoy food and to eat a diet that maintains nutritional status is key to coping with illness. Poor nutrition has been shown to increase the risk of infections, bed sores, chest infections and poor wound healing. Good nutritional status will help ensure a quicker recovery. Other common problems:Loss of tasteThe ability to taste flavours declines as we age. Food can often taste bland to older people so try:Using herbs and spices, tomatoes and other flavouring such as lemon juice to flavour food, but avoid using too much saltChoosing foods with a strong taste - go for strong-flavoured meats, sauces, dressings, mustards and picklesLoss of interest in foodOlder people can lose interest in food for a variety of reasons. Depression due to loss of independence or bereavement, or simply eating alone can reduce appetite.Explore the possibility of lunch clubs in your areaEat with company when you canMake meal times special by laying the table and presenting food in an attractive wayChoose a variety of foods where possible to keep the experience interesting Poor appetiteIf you're unable to eat much, try small appetising meals and calorie-rich snacks in between meals to boost nutrient intake. To increase your calorie intake, try the following tips:Fats and sugars provide energy and help food to taste good, so use these generously. Add extra cheese to sauces or grate on potatoes, add butter or margarine to vegetables, or enrich full-fat milk by adding dried milk powder. Try using sugar or honey on breakfast cereals.Eat pudding once or twice a day, such as yoghurt, milky puddings, ice cream, trifle, cake, fruit pie, sponge puddings with custard and ready prepared desserts. Cakes, biscuits, chocolate and crisps provide extra energy when eaten with meals, but ensure they don't spoil the appetite for more nourishing foods.Enriched-nourishment drinks, available from pharmacies and supermarkets, may be taken between meals to increase calorie intake, but shouldn't replace meals.Alcohol in small amounts can actually stimulate the appetite, but check with your GP first, especially if you're taking medication.
Health And Beauty: Children's weight

In the UK, the number of obese children continues to rise. Currently, just under one in five children between the ages of two and ten is obese.Obese children tend to become obese adults. This increases the risk of developing certain diseases, such as type 2 diabetes. If you think your child might be overweight or obese, check with your GP. They'll be able to advise you on how to provide the right support for your child to help slow or halt their weight gain and allow them to grow into their weight.Even if your child doesn't have a weight problem, it's important to establish healthy eating habits early on so they don't gain any excess weight.Good nutrition in childhood is vital for growth and development. Establishing healthy eating and activity patterns while children are young can lead to life-long habits that will help to determine whether or not they're healthy as adults.What's a healthy diet?Children need a varied diet that provides enough energy and protein for growth and repair, and contains all the essential vitamins and minerals. Encouraging by exampleThe best way to improve your child's diet is for them to see you enjoying healthy food options.Introduce new foods from an early age. It's normal for children to reject new foods at first, but this doesn't mean they'll never like them. Research shows most children will eat them if you try again a few days later.Don't pressure your child to clear their plate. Encouraging them to eat when they're not hungry can result in them eating more calorie-rich foods. It may also lead weaken your child's innate ability to respond to signals of hunger or fullness, so that they overeat.Small children need to eat regularly, but keep snacks to defined times rather than allowing continual grazing. Snack foods don't have to be sweets or biscuits. Try slices of fruit or vegetable sticks instead.Portion sizePortion sizes have increased over the years, especially when it comes to ready meals and snacks. This means children have become used to eating more calories than they need. High nutritional quality is more important than large quantities. Small children don't need as much food as adults. Think twice when serving meals and make sure theirs is smaller than a typical adult serving.Avoid the supersize, kingsize and '25 per cent extra' foods. Seek out mini and fun-size foods instead.TreatsSnacks during the day should be planned rather than spontaneous, so children can establish feelings of hunger and fullness. Offering a sweet pudding as a reward when your child eats their greens reinforces the idea that vegetables are unpleasant and something to be endured, while desserts are a treat. Try offering non-food rewards, such as a story or trip to the park, instead.Foods such as cakes, sweets, crisps and sugary drinks should be kept as party or holiday foods, not everyday items.How many calories?The following table shows the estimated average daily calorie requirements for young children. The figures assume the child is of average weight with reasonable physical activity levels. It should be used as a guide only.[an error occurred while processing this directive] Encouraging activityChildren are naturally active, so don't stop them tearing round the house even if you're craving a few minutes of peace and quiet.Some sedentary behaviour, especially watching TV, is linked to increased intake of food, especially those high in fat, salt and sugar. If your child demands snack foods, try plain popcorn, vegetable sticks or slices of fruit instead.Better still, turn off the TV or computer and get them out riding their bike, playing in the park or doing any physical activity they enjoy.
