No, A High-Protein Diet Is Not Affecting Your Kidney

A recent study has debunked the myth that high-protein diets could cause kidney damage in healthy adults. The McMaster University meta-analysis has been published in the Journal of Nutrition. The scientists challenge the perceived dangers of a protein-rich diet, a notion first introduced in the 1980s, which suggested that processing large amounts of protein leads to a progressive decline in kidney function over time.

“It’s a concept that’s been around for at least 50 years and you hear it all the time- higher protein diets cause kidney disease,” said Stuart Phillips.

“The fact is, however, that there’s just no evidence to support this hypothesis in fact, the evidence shows the contrary is true: higher protein increases, not decreases, kidney function,” Stuart added.

 

Health experts routinely advocate the benefits of protein for many reasons. It boosts metabolism, increases satiety making one feel fuller for longer, promotes fat loss, helps build muscle during weight training and helps to preserves muscle, particularly in the elderly.

However, the impact of protein on kidney function is much more contentious, particularly its effect on the glomerular filtration rate (GFR), which is a test to measure how well the kidneys filter blood and remove waste.

“While there is a breadth of evidence showing the benefits of higher protein consumption, some people are still afraid it could cause kidney damage,” said Michaela Devries-Aboud, lead author of the study.

“With these findings, we have shown that a higher protein diet is safe. In fact, it should be viewed as an important tool for muscle health across an entire lifespan,” the author added.

Researchers analysed data from 28 papers dating from 1975 to 2016, examining the effects of a low or normal protein intake versus higher protein diets on GFR in healthy individuals.

The publications involved more than 13-hundred participants, including those who were healthy, obese, or had type 2 diabetes and/or high blood pressure. None of the participants was diagnosed with chronic kidney disease and all consumed either a high, moderate or low-protein diet.

A high-protein diet included either 1.5 grams of protein per kilogram of body weight per day, at least 20 percent of total caloric intake coming from protein or at least 100 grams of protein per day.

“There is simply no evidence linking a high-protein diet to kidney disease in healthy individuals or those who are at risk of kidney disease due to conditions such as obesity, hypertension or even type 2 diabetes,” says Devries-Aboud.

According to Phillips, “Protein causing kidney damage just lacks any support. I think we can put this concept to rest.

Fruit and Vegetable Juices That Enhance the Immune System

The Kashmir Monitor

Published

on

Everyone knows that fresh fruits and vegetables are loaded with nutrients that offer a wide range of benefits for the mind and body. Certain fresh produce help enhance your immune system, making it possible for you to easily avoid various infections and diseases. Juicing the following allows you to boost your immunity in a truly refreshing and delectable way:

Carrots

The sweetness of carrot juice makes it loved by kids and adults alike. Carrots get their characteristic bright orange color from its rich supply of beta carotene, a nutrient converted into vitamin A for sharper vision and better eye health. More importantly, vitamin A is an essential nutrient for a stronger immunity.

 

Lemon

Vitamin C in lemons makes these citrus fruits excellent boosters of your immune system. Vitamin C is a well-known powerful antioxidant that protects the body from colds, cough, flu and others. Lemon juice may be acidic, but it has an alkalizing property once ingested, helping to restore optimal pH balance in the body.

Apples

Other than vitamins and minerals, apples also contain plenty of insoluble fiber. This type of carbohydrates that cannot be digested by the body works as a broom that sweeps out toxins along the intestinal tract. With all of those accumulated poisonous substances out of your body, your immunity is in top-form.

Kiwi

When it comes to fruits, some of the best sources of vitamin C are kiwis. Other than this super antioxidant, kiwis also contain vitamins A and E, both of which are necessary for a stronger immune system. Insoluble fiber and potassium in these fruits are also highly favorable for your cardiovascular system.

Cranberries

Cranberry juice is admired for its ability to bolster the urinary tract system. However, it also contains plenty of vitamin C that helps safeguard you from illnesses brought about by invading microorganisms such as bacteria and viruses.

Broccoli

A vegetable that makes for an excellent immune-boosting juice is broccoli, thanks to its rich supply of beta carotene and vitamin C. Every glass of broccoli juice also provides your body with sulphur, a mineral with powerful antimicrobial properties. Sulphur promotes healing as well because it detoxifies the body at a cellular level.

Beets

What makes beet juice capable of supporting the immune system is its long list of vitamins and minerals. Some of them include vitamins A and C, iron, calcium, potassium and manganese. When juicing, it’s a good idea to mix beets with other fruits and vegetables of your choice due to its strong, earthy flavor.

Reduce asthma symptoms with Omega-3

A new study has found that consuming a diet rich in omega-3 fatty acids is linked to fewer childhood asthma symptoms which are triggered by indoor air pollution.

The study published in ‘American Journal of Respiratory and Critical Care Medicine’, lays out that families and health care providers may be able to protect children from harmful effects of indoor air pollution by serving a diet rich in omega-3 fatty acids while reducing foods rich in omega-6 fatty acids such as soyabean oil and corn oil.

“Our group is working on ways to reduce the levels of indoor air pollution in Baltimore City homes,” said lead author of the study, Emily Brigham. “Results are promising, but we don’t want to stop there,” Brigham added.
The study found that for each additional gram of omega-6 intake, children had 29 per cent higher odds of being in a more severe asthma category.

 

Conversely, with each 0.1-gram increase in levels of omega-3 fatty acids in the diet, researchers saw 3 to 4 per cent lower odds of daytime asthma symptoms.

Indoor air pollution, from sources including cooking, cleaning activities and cigarette smoke, is a known trigger for asthma symptoms.

Omega-3 fatty acids, which are found abundantly in fish and certain nuts and seeds, are considered healthy as they are known to reduce inflammation.

Omega-6 fatty acids, primarily found in vegetable oils (including corn, soybean, safflower, and sunflower), as came out in other studies, have mixed effects on health, but have the potential to promote inflammation.

The researchers, however, noted that it doesn’t prove the relationship between fatty acids and asthma severity.

“Among populations known to be disproportionately affected by asthma, we may find that improving diet and air pollution together has the greatest impact on health,” said Brigham.

New cell that can heal hearts discovered

The Kashmir Monitor

Published

on

Researchers have discovered a previously unidentified cell population which could lead to new treatments for patients with injured hearts.

The cell, described in the journal Immunity, was discovered in the pericardial fluid found in the sac around the heart of a mouse with heart injury. The researchers from the University of Calgary in Canada found that a specific cell, a Gata6+ pericardial cavity macrophage, helps heal an injured heart in mice.

The same cells were also found within the human pericardium of people with injured hearts, confirming that the repair cells offer the promise of a new therapy for patients with heart disease. “Our discovery of a new cell that can help heal injured heart muscle will open the door to new therapies and hope for the millions of people who suffer from heart disease,” said Paul Fedak, a professor at the University of Calgary.

 

“The possibilities for further discovery and innovative new therapies are exciting and important,” said Fedak. Heart doctors had never before explored the possibility that cells just outside the heart could participate in healing and repair of hearts after injury, researchers said.

Unlike other organs, the heart has a very limited capacity to repair itself which is why heart disease is the number one cause of death in North America, they said. “We always knew that the heart sits inside a sac filled with a strange fluid,” said Fedak. “Now we know that this pericardial fluid is rich with healing cells. These cells may hold the secret to repair and regeneration of new heart muscle,” he said.
