Detoxify your body

Today we live at a pace that would have seemed unbelievable and indeed impossible to our grandparents. With the increasing demand of jobs, long travel, odd working hours, bringing up children and hectic social lives, we tend to become tired and rundown. Besides our bodies are under constant assault from pollutions, stress, bad posture, sedentary jobs and own bad eating habits. Over a period of time, these effects build up and emerge in many different forms; everything from passing infections, skin eruptions, headaches and digestive problems to serious conditions, such as ulcers, cancers and heart diseases.

The more we overload over body, the more it sinks under the strain. When we begin detoxification, we give our bodies the chance to repair and cleanse and restore a more balance state to the entire system. Detoxification shows up in number of ways. Besides achieving a healthy weight, you can expect to have a clearer skin, healthy looking hair, strong nails and more energy. Detox also has a very calming effect on the mind, particularly if it is combined with meditation. Above all this, it puts you on the right course of long term health.

 

How it works?

Our bodies are completely complex organisms in a state of constant growth and renewal on cellular level. When we pour toxins into our bodies, it treats these as a matter of urgency and works on processing them to render them harmless. This leaves the body with less energy for everyday processes of cleaning, healing and renewal. With increasing demands over a period of time, the body is unable to keep up the pace and the strain begins to show on the overworked liver and kidneys, leading to slowing down of body's performance.

When we detox, two things happen; first, we stop overloading the body with harmful substances and secondly, we give it plenty of the right nutrients to actually speed up the elimination of old toxins and promote cell renewal. As you rejuvenate, the cells become healthier and you look and feel younger.

 

Super scavengers

The World Health Organisation (WHO) had clearly stated that Vitamin A, C and E are vital for health. These vitamins, together with mineral selenium are known as antioxidants. They can protect us not only against minor infections but also serious degenerative diseases such as cancer and heart diseases, as well as conditions that come with premature ageing. They work by acting as scavengers for free radicals.

We clearly need as many anti-oxidants as we can get. One of the best places to find them is in fresh fruit and vegetables and that is why these foods are vital for detoxification. Many nutrients are destroyed by cooking and that is why raw food is much more effective as a source of health and forms the core of a healthy diet plan.

Raw food and fresh juices have remarkable cleansing and regenerating effect on the entire system, as they retain, all their nutrients which might get destroyed while processing and cooking. Juices, both fruit and vegetable are essential part of the whole process. Besides, they are easily assimilated by the body and contain all the nutrients present in raw fruits and vegetables. You can also choose from a wide range of delicious soups and salads. Try to incorporate these eating habits into your daily diet. You can eat as much as you want of the salad and soup meals. Remember to snack on as much fruit as you want during the day, as well as having at least two fresh juices daily, herb teas and of course, lots of water.

The detox diet helps to cleanse your system. The plan begins with a juice fast, which eliminates toxins at a very low level, and then continues with a highly nutritious food that promotes cellular renewal. The diet might last for two to four weeks. By the fourth week you will be on your way to establish a healthy diet for future. Below is an example of what a detox diet, might look like to begin with:-

The first two days

Breakfast: Natural yogurt with seeds, apple and carrot juice.

Mid Morning: Apple

Lunch: As much salad as you like, made from any of the following raw ingredients; cucumber, peppers, radishes, sprung onion, any kind of salad leaves.

Mid afternoon: Apple

Supper: As much as fruit salad you like made from fresh fruits with orange or apple juice as sweetener.

You might drink plenty of water and herb tea throughout the day.

The whole idea of a detox programme is to remove the toxins from your body caused by substances such as alcohol, tobacco and food consumed during the festive period. This programme helps your body by cleaning out the toxins that you have absorbed, by passing them from your skin, liver and kidneys, which act as cleansing filters. The whole idea of a detox diet is to strengthen up the organs that your body uses to carry out detoxification of the toxins on a normal day-to-day basis and release the toxins that have become stored up in your body. The programme involves fasting on liquids for two days, followed by a carefully planned five day diet to allow the digestive system to rest.

 

Different ways to detox

The best and probably the most cost effective way of being able to remove the toxins from your body is to start eating more fresh fruits and vegetables, try not to add too many spices or oil to them. Steamed vegetables are a better option in order to retain the vital nutrients that you require to assist your body during the detoxification period. Orange, yellow and red-orange foods are rich in carotenoids such as beta-carotene, lutein and lycopene. More than 600 carotenoids occur naturally, but carotenes are the most widely known. Carotenes, destroy free radicals in lipids, enhance immune response and protect cells against UV radiation. Green plants on the other hand, contain particularly large amounts of chlorophyll, which is a detoxifier.

Scary truths about your bones

While bones become more fragile with age, structural weakening begins much earlier and is invisible. One in two women over fifty will have an osteoporosis related fracture in her life-time and some women might have to face it in their twenties and thirties…

If you think youíre too young to be worrying about osteoporosis think again. While bones become more fragile with age, structural weakening begins much earlier and is invisible. One in two women over fifty will have an osteoporosis related fracture in her life-time and some women might have to face it in their twenties and thirties.

When youíre in your mid 20s to mid 30s you build bone as fast as you lose it. But once youíre about 35 your start to lose more bone than you gain meaning that your skeletal framework slowly erodes. Osteoporosis is the cause of almost all hip fractures in women over 50 (usually elderly and frail they have other medical conditions that worsen when they are bedridden.)

Even if your doctor isnít talking about osteoporosis that doesnít mean itís not happening to you. Ignorance about bone disease whether on your doctorís part or your- is an unrecognised risk factor.

Here are seven scary truths that could be threatening your skeletal health.

Calcium supplements arenít a cure: Calcium is critical to keeping your bones healthy but itís not all you need. Indeed many studies are finding that certain foods protect bones more effectively than pills. You can help maintain your bones by eating foods containing vitamin D needed for absorption of calcium (milk fortifies breakfast, cereals, egg yolks) and vitamin K which may also aid calcium absorption (dark green leafy vegetables like spinach broccoli and cabbage).

Preliminary findings by US researches indicate that postmenopausal women who ate broccoli at least three times a week over one year were 80 percent less likely to fracture a hip, than those who consumed broccoli less than once a week.

Donít assume your doctor is checking for osteoporosis: Getting shorter is a tell tale signs of bone loss but your doctor wonít notice it unless he or she measures you periodically after menopause. In addition if you have risk factors for osteoporosis ask your doctor if you need a bone density test and whether you should change your diet or exercise habits. If your doctor doesnít take your concerns seriously find another one.

Breaking a bone in your 30s isnít just bad luck: Unless itís from a high speed car crash or a fall out of a window a young woman shouldnít break a bone. If you break a bone after tripping and falling or get a fracture for not apparent reason your doctor should refer you for a bone density test. If he or she doesnít find one who will.

Researches recently found that women and men with unexplained foot fractures had low bone density. Mysterious fractures appear to be a bad omen for your health too. "A fracture increases your risk of subsequent fractures elsewhere in the body," says Dr Beatrice Edwards director of an osteoporosis programme in Chicago.

A bone density test may not reveal your risk: Youíve probably run across one of those non-invasive ultrasound machines which look for signs of thinning bones in wrists fingers and heels. But a normal result based on a peripheral site may not be a precise assessment of your skeletal health.

Bone loss is not uniform throughout the body. People may lose more in one site than in another. The crucial points to measure are the hip and spine where the most serious fractures occur.

One highly recommended test is the specialised x-ray known as DEXA (dual energy x-ray absorptiometry). This measures bone density in the hip spine or less accurately forearm.

Your parentsí poor posture is your problem too: Osteoporosis runs in families. "Genetics can be very important in this disease and it looks like it can be transmitted through both maternal and paternal sides," says Dr Felicia Cosman, Clinical Director of the (US) national osteoporosis foundations. Whatís more recent research suggests that a hereditary link may be especially strong at specific sites such as the spine hip and wrist.

If your father mother or grandmother lost more than two inches in height or developed a stoop or either parent suffered any fracture as an adult take preventive steps. Ask your physician if you would benefit from hormone replacement therapy (the oestrogen in it could protect your bones) in additions to modifying your diet and exercise routines.

Thereís no pill to cure osteoporosis: "Medications called bisphosphonates replace some bone that was lost and reduce the risk of fractures but nothing can completely reverse whatís gone," says Cosman. With hormone replacement therapy while osterogen increase calcium absorption decrease calcium loss and inhibits the destructions of bone any bone protections quickly ebbs one you stop HRT.

Parathyroid hormone being reviewed new drug currently being reviewed in the USA for its potential to make new bone cells. PTH is a natural hormone protein that regulates calcium and triggers new bone formation. In a study reported in the Massachusetts medical societyís Health News women with osteoporosis who took daily injections of PTH showed a marked increase in bone mineral density.

Brain wired for adventure

Brain is the key organ of the human body. It can be extremely complex but adventurous at times. Brain is the one that compels us to shift our desires from one object to the other. Scientists have identified a key region of the brain which encourages us to be adventurous. The region, located in a primitive area of the brain, is activated when we choose unfamiliar options, suggesting an evolutionary advantage for sampling the unknown.

The experimental evidence was gained by University College London (UCL) researchers who carried out tests on volunteers while using an FMRI scanner to observe the brain at work. The volunteers were shown a selection of images, which they had already been familiarised with. Each image had a unique probability of reward attached to it and over the course of the experiment the volunteers would be able to work out whose selection would provide the highest rewards. However, when unfamiliar images were introduced, the researchers found that volunteers were more likely to take a chance and select one of these options than continue with their familiar (and safer) options.

UCL's Dr Bianca Wittmann showed that when the subjects selected an unfamiliar option, an area of the brain known as the ventral striatum lit up, indicating that it was more active. The ventral striatum is in one of the evolutionarily primitive regions of the brain, suggesting that the process can be advantageous and will be shared by many animals.

'Seeking new and unfamiliar experiences is a fundamental behavioural tendency in humans and animals. It makes sense to try new options as they may prove advantageous in the long run. For example, a monkey who chooses to deviate from its diet of bananas, even if this involves moving to an unfamiliar part of the forest and eating a new type of food, may find its diet enriched and more nutritiousî, said Dr Wittmann.

The ventral striatum is one of the key areas involved in processing rewards in the brain. Although the researchers cannot say definitively from the FMRI scans how novelty seeking is being rewarded, Dr Wittmann believes it is likely to be through dopamine release.

Interestingly, however, whilst rewarding the brain for making novel choices may prove advantageous in encouraging us to make potentially beneficial choices, it may also make us more susceptible to exploitation.

Red meat consumption linked to colorectal cancer

Colorectal cancer, or cancer of the rectum and large intestine (colon), is a major public health problem in every corner of the world. Roughly speaking, a diet containing less than 40 grams of animal fat per day conveys one-half the risk of colon cancer of a diet containing 65 grams or more per day. According to recent findings, consuming more than 18 ounces, or a little over a pound, of red meat each week can significantly increase a person's risks for developing colorectal cancer. Every ounce and a half of red meat a person eats over 18 ounces increases their risks by 15 percent.

 

Automated, wearable kidney offers continuous dialysis

UCLA team develops device giving patientís freedom of movement and better quality of life. An automated artificial kidney that can be worn on the body may one day be to dialysis patients what the insulin pump is to diabetes patients.

The automated, wearable artificial kidney (AWAK) works better than conventional dialysis. UCLA-VA has already signed an exclusive licensing agreement with AWAK Technologies Pte. Ltd., Singapore, to develop the design. The AWAK, which is bloodless, improves upon a previous artificial kidney that was portable but not actually wearable. It improves greatly on conventional dialysis, which requires patients to be connected to a machine for hours. The new machine would function 24/7, as do actual kidneys, so it would present fewer shocks to the patient's system.

 

Blood pressure drugs may protect against Alzheimer's

The use of blood pressure drugs called angiotensin receptor blockers (ARBs) is associated with lower incidence and slower progression of Alzheimer's disease, researchers at the Boston University School of Medicine report. The study found that people with Alzheimer's disease or dementia who take ARBs are up to 45 percent less likely to develop delirium, to be admitted to nursing homes, or to die. The results indicate that ARBs might protect people against Alzheimer's disease and dementia, the researchers said. It's not clear why ARBs may be beneficial, but it may be because they help prevent nerve cell injury from blood vessel damage or help promote nerve recovery after blood vessel damage, the researchers said.

 

Some sweeteners inhibit enzyme tied to type-2 diabetes

Certain kinds of sweeteners such as date sugar and dark brown sugars may help manage type-2 diabetes and related complications, American and Brazilian researchers say. Depending on their origin and grade of refining, many sweeteners contained significant amounts of antioxidants, which have the potential to control diabetes-linked high blood pressure and heart diseases, Kalidas Shetty, University of Massachusetts Amherst said. The researchers analysed a wide variety of sweeteners and found that date sugar and dark brown sugars contained much higher levels of antioxidants called phenolic compounds than white sugar. Diabetes is characterised by a rapid rise in blood glucose levels after meals. Replacing sugars in processed foods and beverages with low-calorie and noncaloric sweeteners are one long-term strategy for type-2 diabetes, Shetty said.
