Did you know that over 40-year-olds might lose up to 8 per cent of their muscle mass every decade? After the age of 70, the pace of decrease may double.
Sarcopenia, or advanced muscle loss, affects roughly one-third of persons over the age of 50. Muscles are crucial for organ function, skin health, immunity and metabolism, as well as for common physical acts like picking things up, reaching for something, opening a jar or getting out of a chair. To put it another way, keeping muscle mass as you become older is critical to living a happy and healthy life.
"Muscle loss is an ageing factor that is rarely discussed, and people accept its signs, such as a loss of strength and energy, as a natural part of ageing," says Ganesh Kadhe, Associate Director Medical and Scientific Affairs at Abbott Nutrition.
"However, muscle fitness can often predict how we will age and remain active and independent."
The good news is that you may assist, prevent or delay muscle loss by taking the appropriate precautions. While muscle loss is unavoidable as we age, it does not have to be.
To stay strong as you age, start following the tips below to fuel and keep muscles fit for years to come!
1. Engage in regular exercise, including resistance training, to maintain muscles and strength.
2. Eat good source of protein from lean meats, eggs and beans; aim for 25-30 grams of protein at every meal.
3. Choose a balanced diet full of veggies, fruits, whole grains, proteins, healthy fats and key vitamins and minerals like calcium and vitamin D.
4. Consider taking other muscle health ingredients, like HMB.
5. Talk to your healthcare provider about nutrition, especially if you are ill, hospitalised or recovering from surgery, to manage illness-related muscle loss.

With a whopping 77 million people in India living with diabetes, a simultaneous and sharp rise has been observed in the prevalence of diabetes-related preventable vision loss, particularly among the young people, say experts.
Diabetic retinopathy is a chronic, progressive retinal disease that is a leading cause of vision impairment in today's young adults, working population. It's of major concern among children suffering from juvenile diabetes (Type-1 diabetes) and especially if they have had diabetes for over 10 years.
It is estimated that approximately 1.1-crore people are suffering from retinal disorders in India and more alarmingly, about one in every three people living with diabetes have some degree of diabetic retinopathy, a diabetes complication that affects eyes.
"With the growing incidence of diabetes, it has been estimated that diabetic retinopathy affects one in three people with diabetes and remains the leading cause of blindness in young working-aged adults," Dr Mahipal Sachdev, Medical Director and Chairman, Centre for Sight Group of Eye Hospital, told IANS.
"Approximately 7-10 per cent of young diabetics will go on to develop diabetic retinopathy, of which 2-4 per cent will have vision threatening sequelae if not taken proper treatment." added Dr. Aditya Sudhalkar, M.S. Ophthalmology, Consultant Vitreoretinal Surgeon.
The most common form of diabetic retinopathy is Diabetic Macular Edema (DME) which arises when the damaged blood vessels swell and flow into the macula of the retina causing visibility issues in the normal vision.
According to Dr. Chaitra Jayadev, senior vitreo-retinal consultant, Narayana Nethralaya Eye Institute Karnataka, studies have shown that the prevalence of DME and diabetic retinopathy is higher and more severe in young diabetics with a longer duration of diabetes.
"Diabetes in the younger is a distinct pathological entity characterised by a more aggressive presentation and manifestation. An earlier onset of diabetes leads to a longer exposure to insulin resistance and hyperglycemia. This gives rise to a greater propensity for developing long-term microvascular and macrovascular complications," Dr. Jayadev said.
Thus, screening for diabetes is of utmost importance, even if one is "young" and has no symptoms. It becomes more crucial if one has risk factors such as family history, obesity, sedentary lifestyle, or on long term steroid medications.
Dr. Sudhalkar said that in India, there is a general reluctance towards attending clinics and nearly 25 per cent of young patients with DME come late for diagnosis.
"It's important to know, only 11 per cent of diabetic retinopathy patients can actually reverse vision threatening sequelae once they set in. The rest continue to progress even with strict glycemic control," he noted.
"Retinopathy, unfortunately, is the most neglected complication of diabetes. We see so many patients come to OPD where eyes have not been checked for. So the screening, also known as Funduscopy, should be done at the time of diagnosis of Type-2 diabetes, in adults, and in children, five years after the onset of diabetes, and thereafter annually," Dr Dheeraj Kapoor, HOD, Endocrinology at Artemis, Gurugram, told IANS.
If diabetes occurs near puberty, then funduscopy should be checked for potential retinopathy.
"It is important because the condition poses no symptoms in the initial days. And once symptoms set in, such as bleeding in the eye, red vision, sudden loss of vision, it's too late," Kapoor said.
The doctors advised to adhere to the treatment and maintain a healthy lifestyle to effectively manage diabetes and to prevent the onset or progression of eye diseases.

Chronic inflammation caused by obesity may trigger the development of cells that break down bone tissue, including the bone that holds teeth in place, finds a new research.
The study, completed in an animal model, found that excessive inflammation resulting from obesity raises the number of myeloid-derived suppressor cells (MDSC), a group of immune cells that increase during illness to regulate immune function.
MDSCs, which originate in the bone marrow, develop into a range of different cell types, including osteoclasts (a cell that breaks down bone tissue).
"This research promotes the concept that MDSC expansion during obesity to become osteoclasts during periodontitis is tied to increased alveolar bone destruction," said researcher K.H. Kwack from the University at Buffalo.
"Taken together, this data supports the view that obesity raises the risk of periodontal bone loss," Kwack added.
Bone loss is a major symptom of gum disease and may ultimately lead to tooth loss.
Also known as periodontal disease, gum disease affects more than 47 per cent of adults 30 years and older, according to the Centers for Disease Control and Prevention.
For the study, published in the Journal of Dental Research, the team examined two groups of mice fed vastly different diets over 16 weeks -- one group, a low-fat diet that derived 10 per cent of energy from fat, the other group a high-fat diet that drew 45 per cent of energy from fat.
The investigation found that the high-fat diet group experienced obesity, more inflammation and a greater increase of MDSCs in the bone marrow and spleen compared to the low-fat diet group.
The high-fat diet group also developed a significantly larger number of osteoclasts and lost more alveolar bone (the bone that holds teeth in place).
Also, the expression of 27 genes tied to osteoclast formation were significantly elevated in the group fed a high-fat diet.

Sleep is an essential function that helps in recharging our bodies and minds. Moreover, healthy sleep also helps the body in remaining fit and it staves off any diseases. When we do not get enough sleep, our brain does not function properly and it can impair our abilities to concentrate, think clearly and process memories. An adequate amount of sleep that an adult requires ranges from seven to nine hours.
However, work schedules, day-to-day stressors, a disruptive bedroom environment and medical conditions can prevent us from receiving adequate and peaceful sleep. Hence, a healthy diet and good lifestyle habits can ensure a good amount of sleep each night. However, for some people chronic lack of sleep may be a sign of a sleep disorder.
Sleep reflects one's state of mind and overall health in general. A good sleep is one which is age appropriate in duration, qualitatively divided into various sleep stages of adequate periods and which eventually makes a person feel refreshed in the morning and through the day. Although there is a wide variation in the amount of total sleep required by healthy adults to maintain a good daytime function, it is widely accepted that a good, consolidated 8 hours of uninterrupted night-time sleep is essential for majority of adults.
An adequate amount of sleep duration is extremely important to maintain good mental and physical health. A sleep deprived person often experiences decline in cognitive function, poor memory, inability to concentrate on tasks at hand and easy irritability with frequent mood swings. Even if the sleep duration is adequate, an interrupted and disrupted sleep with poor sleep quality devoid of deep sleep is also associated with excessive daytime sleepiness with declining cognitive function.
Lack of good sleep, both in terms of duration and quality, can adversely affect the physical wellbeing with such individuals being more prone to develop both infectious as well as lifestyle related diseases. With the millennial generation adopting a 24-hour lifestyle without any defined periods of sleep, increase in the total screen time during COVID-19 lockdowns due to exponential increase in online classes and meetings, and poor sleep hygiene, have all resulted in a variety of sleep disorders.
Ultimately, this very important aspect of keeping people healthy is not only being ignored but also leading to abuse of sleeping pills, alcohol and smoking. With rising stress levels and a constant pressure to meet deadlines, it is extremely important to maintain a work life balance and give oneself adequate opportunity and time to have a good night sleep. If anyone experiences any kind of sleep related issues, these should be brought to the immediate notice of the sleep physicians and expert opinion must be taken for timely diagnosis and management.
All in all, sleep is good and necessary. For adults, getting at least seven hours of sleep ensures proper daytime functioning which involves being alert for the day and being able to concentrate and not moody and tired through the day. Creating a night time routine that ensures that your mind and body are relaxed can be helpful in ensuring a good sleep for all individuals.(By Ayush Gupta)

In many households, including in India, it is a ritual to step out for a walk after dinner before hitting the sheets. Many also take a quick walk after lunch. The goal? To improve digestion.
But, is walking after eating really beneficial for digestion? Turns out it is, and here's why:
After you finish your meals, your body gets to work, it breaks down and absorbs the nutrients. A significant portion of the food breakdown or digestion takes place in the small intestine. Research suggests that walking after a meal can help in the faster transit of food from the stomach and into the small intestine.
How does this help? "The faster the food transits from your stomach into the small intestine, the lesser is you the likelihood of common complaints like bloating, gas, and acid reflux. Evidence also indicates that a post-meal 30-minute walk, coupled with routine exercise, can improve bowel function and lower the chances of constipation.
Postprandial walks not only ease digestive symptoms but can be quite beneficial for individuals with type-2 diabetes. Research from the New Zealand's University of Otago indicates that for people with type-2 diabetes, walking after meals is better at reducing blood sugar levels, especially following carb-rich meals. How does that happen? The body converts food into glucose, which is a major source of energy for the body. After consuming a meal, the blood glucose levels start rising.
In order to deal with this spike, the body secretes insulin, which helps drive the glucose into the cells. However, for diabetic individuals, the action of insulin is impaired, preventing the process of managing blood sugar levels. This can lead to high levels of glucose in the blood, increasing the risk of health problems. During a post-meal walk, glucose is utilized by the body to produce energy for the activity, aiding in lowering the level of glucose in the blood.
Now to address a key question - how long should you wait after a meal before you set off on your walk? Walking immediately following a meal may cause acid reflux and upset your stomach. "It is advisable to walk after a gap of 30-45 minutes after your lunch or dinner to experience the most benefits," says Singh.
It is also recommended to walk at an easy to moderate pace after your meals as increased intensity workouts may cause more blood to be drawn towards the working muscles and away from the gastrointestinal tract. This may cause your digestion to slow down and may also lead to indigestion.
Along with health benefits, a post-meal walk will also bring you closer to your goal of hitting 10,000 steps (a popular aspirational fitness goal) a day. Any sort of physical activity also triggers the release of endorphins, or ï¿½feel-good hormones', thereby relaxing the body. A post-meal walk is a positive step in that direction.
Now that you know the many benefits of a quick post-meal walk, it is time to make this small lifestyle change for better health and overall fitness.(By Vikas Singh)

Negative calorie food refers to those items that consume more energy during their digestion, in comparison to the amount of energy they gives to the body. We can say that the calorie cost of digesting the food would be greater than its energy content.
These foods are typically high in fibre and have a low glycaemic index. Calories are an important component of food and everything we eat has calories. Calories are of two types. One is empty calories which don't have much nutritive value but just has calories and promotes weight gain. Foods with high fibre and water content usually have fewer calories and we need more energy to digest them, these are called negative calorie foods. These foods help to lose weight as they are not only low in calories but also help to burn out more calories than others. Most negative calorie foods are plant-based.
Here we are sharing the following 10 negative calorie foods:

Colourful berries such as blueberries, strawberries, raspberries typically contain just 32 kcal for a half-cup quantity. Berries are called negative calorie foods because of their low glycaemic index and their protein content. It also contains antioxidants, which protects us from various cancers.
It has 19kcal/100g. Apart from its water content, it is an excellent source of fibre, potassium and vitamin C. Tomatoes also contain lycopene, an antioxidant known to protect us from skin cancer.
They contain 41 kcal/100g. Its vitamin A content is good for the eyes. Carrot fibre content keeps the stomach full for a longer time thus helps in weight loss.
It contains 15 kcal/100g. This vegetable has high water content which is great to satisfy thirst along with providing all the necessary vitamins and minerals. The water content present in cucumbers is great for hydration. Along with quenching thirst, this fruit provides dietary fibre and is good for irritable bowel syndrome and diabetic patients.
It has 30 kcal/100g. Some of the benefits of watermelon rind include a healthy heart, provide hydration and regulation of blood pressure. Additionally, watermelon seeds also have many health benefits starting from the prevention of anaemia to immune-boosting properties. The water content present in watermelon and vitamins A, B6, C along with lycopene act as an immune-boosting food.
It provides 52 kcal/100g. Apple contains a good amount of antioxidants, vitamin C and fibres. Apple's high fibre content helps in weight loss and it also helps to boost cognitive performance. Quercetin, an antioxidant present in apples, is also associated with lowering the risk of type 2 Diabetes.
It contains 34 kcal/100g. Its vitamin A content improves vision. Calcium, Phosphorus, vitamin K content is essential for healthy bone development. Iron and folic acid help to prevent anaemia.
