Body in shape-wefornews

London, Oct 14, 2017: Want to live a long life? Reducing excess weight and staying in shape may prolong life expectancy by two months, researchers suggested.

The study showed that people who are overweight cut their life expectancy by two months for every extra kilo of weight they carry.

Cigarette smoking and traits associated with lung cancer also had the greatest impact on shortening lifespan.

In addition, body fat and other factors linked to diabetes also have a negative influence on life expectancy, the researchers mentioned.

“Our study has estimated the causal effect of lifestyle choices. We found that, on average, smoking a pack a day reduces lifespan by seven years, whilst losing one kilogram of weight will increase your lifespan by two months,” said Peter Joshi, researcher at the University of Edinburgh in Scotland.

The team took the data from 25 separate population studies and analysed genetic information from more than 600,000 people alongside records of their parents’ lifespan.

People share half of the genetic information with each of their parents. Therefore, certain lifestyle factors become highly influenced by some genes that further impacts life expectancy of people, like, increased alcohol consumption and addiction, the researchers explained, in the paper published in the journal Nature Communications.

The study also identified two new DNA differences that affect lifespan. The first in a gene that affects blood cholesterol levels and reduces lifespan by around eight months.

The second is a gene linked to the immune system which adds around half a year to life expectancy.

“The power of big data and genetics allow us to compare the effect of different behaviours and diseases in terms of months and years of life lost or gained, and to distinguish between mere association and causal effect,” said Jim Wilson, Professor at the varsity.

Heart patients who walk faster hospitalised less

London, April 22 (IANS) Increasing the pace of walking may bring some added benefits as researchers have found that faster walking patients with heart disease are hospitalised less.

“The faster the walking speed, the lower the risk of hospitalisation and the shorter the length of hospital stay,” said study author Carlotta Merlo, a researcher at the University of Ferrara in Italy.

“Since reduced walking speed is a marker of limited mobility, which has been linked to decreased physical activity, we assume that fast walkers in the study are also fast walkers in real life,” she added.

The study was conducted in 1,078 hypertensive patients, of whom 85 per cent also had coronary heart disease and 15 per cent also had valve disease.

A total of 359 patients were identified as slow walkers, 362 intermediate and 357 fast walkers.

The researchers recorded the number of all-cause hospitalisations and length of stay of the participants over the next three years.

During the three year period, 182 of the slow walkers (51 per cent) had at least one hospitalisation, compared to 160 (44 per cent) of the intermediate walkers, and 110 (31 per cent) of the fast walkers, according to the study published in the European Jo

urnal of Preventive Cardiology.

The slow, intermediate and fast walking groups spent a total of 4,186, 2,240, and 990 days in hospital over the three years, respectively.

The average length of hospital stay for each patient was 23, 14, and 9 days for the slow, intermediate and fast walkers, respectively.

Each 1 km/hour increase in walking speed resulted in a 19 per cent reduction in the likelihood of being hospitalised during the three-year period.

Compared to the slow walkers, fast walkers had a 37 per cent lower likelihood of hospitalisation in three years, the findings showed.

“Walking is the most popular type of exercise in adults. It is free, does not require special training, and can be done almost anywhere. Even short, but regular, walks have substantial health benefits. Our study shows that the benefits are even greater when the pace of walking is increased,” Merlo said.

New Delhi, April 21: Yogurt, the versatile dairy product, is filled with nutrition and is equally useful for skin and hair. Treat sunburns, acne and improve your immunity with yogurt, say experts.

Himanshu Chadha, Founder, APS Cosmetoofood, and Nmami Agarwal, Nutritionist and Dietician, have listed the goodness of yogurt:

* Treat sunburn: Spread yogurt on the affected area, leave it for 20-25 minutes and then wash it off with lukewarm water. Yogurt is rich in zinc and has anti-inflammatory properties. It also contains probiotics that will help restore your skin’s natural barrier.

Take a cup of yogurt and whip it. Apply it on your scalp, hair and hair ends by massaging it well. Cover your hair with a shower cap and let it rest for 20 minutes, then wash your hair with a mild shampoo.

* Using yogurt, which is full of nutrients that are good for your hair, can help stop hair fall. Due to the presence of vitamin B5 and D, yogurt helps nourish the hair follicles.

A mixture of pepper and curd used daily for washing the hair helps in reducing hair fall. Curd and Amla powder can be mixed together to make a paste that can be applied on the scalp and hair to reduce hair loss.

* Since it is a well-known probiotic food, it helps to flourish the healthy bacteria in your gut which can improve the gastro immune system. Along with this, it aids in digestion by reducing the side effects of the irritant stomach such as diarrhoea, bloating and irritable bowel syndrome.

* Strengthen your bones by adding yogurt to your everyday diet. It will add that daily dose of calcium which your body requires for stronger bones as well as for regulating the bone mineral density.

By having a diet in a combination with calcium and vitamin D, it can work as a treatment for osteoporosis.

* Yogurt works perfectly for women. It is often advised for women to consume freshly prepared yogurt in their diet considering they are powerful for fighting against the yeast infections such as Candida which can be a causing trouble to a lot of women.

Switch to stevia for a sweet, healthy lifestyle

stevia leaf
Stevia leaves have almost no calories and does not increase blood glucose.

New Delhi, April 20: In the midst of today’s hectic lifestyle, let’s spare a thought for one of the biggest threats to our health and general well-being: Excess of processed high calories and sugar. It is said that “prevention is better than cure”. Does this mean we should stop consuming food and drinks which have sugar? Maybe not.

What if someone told you that you can maintain the sweetness in your life without adding any calories? And this, from a natural source with the same sweet flavour that your taste buds love? And, yes, with no harmful side-effects? Sounds too good to be true, but nature has gifted us “stevia” — a plant which has sweetness in its leaves — a sweetness that surpasses that of sugar, sugarcane juice, honey or coconut sugar.

Given that stevia can replace unwanted sweetener calories, it can be the one tool for cutting calories from the Indian diet without affecting blood sugar or insulin levels. Plus, it is safe for people with diabetes and is also tooth friendly.

Here are some of its advantages:

Stevia does not increase blood glucose: Numerous studies have been conducted on the use of stevia and its effects on consumption. The stevia plant’s leaves contain naturally sweet molecules called steviol glycosides, which can be up to 400 times sweeter than sugar, but studies have shown that stevia has no effect on blood glucose levels. Thus, one can consume it without fear of affecting the blood sugar level.

Stevia leaves have almost no calories: It’s a gift of nature that has been used in various parts of the world. The leaves have been used by Guarani Indians in Paraguay for several hundreds of years to sweeten their “matte” (tea). In the 1970s, the Japanese picked it up as a natural sweetening option. Today, it is the No. 1 sugar substitute in Japan and the fastest-growing sweetener in most markets in the developed world like France and the US.

Global safety recognition: Stevia sweeteners are permitted for use in foods and beverages in countries around the globe. Over 200 global studies have illustrated stevia’s safety for the entire family. Studies have also shown that it is safe for pregnant women. Stevia is safe for people with diabetes as it does not contain any calories or carbohydrates and therefore does not affect blood glucose or insulin levels. It has zero glycemic index.

Stevia v/s artificial sweeteners: Realisation of the harm caused to health from consuming excess calories from sugar was the reason that ignited the search for substitutes, or artificial sweeteners. Saccharin, aspartame sucralose and the like became popular substitutes and then went out of favour owing to concerns from public about their origin and perceived lack of safety.

What evidently seals the deal in stevia’s case as a sugar substitute is the fact that it is zero-calorie, zero-fat and 100 per cent natural.

Imagine your rassogulla or gulab jamun without an overload of sugar, serving your child tomato ketchup without thinking of the extra sugar and calories, enjoying a serving of ice cream, cool carbonated drink without any sugar at all. The latest varieties of star leaf stevia can make the greatest taste possible without any harm or guilt.
