Do you eat food more often? According to a study, longer daily fasting times or increasing the duration between meals, regardless of calorie intake as well as diet composition, can make men more healthy and help them live longer, compared to those who eat more frequently, researchers say. In the study, meal-fed and calorie-restricted male mice showed improvements in overall health — common age-related damage to the liver and other organs – and an extended longevity. The calorie-restricted mice also showed significant improvement in fasting glucose and insulin levels.
“Increasing daily fasting times, without a reduction of calories and regardless of the type of diet consumed, resulted in overall improvements in health and survival in male mice,” said lead author Rafael de Cabo, from the US National Institutes of Health (NIH).
“Perhaps this extended daily fasting period enables repair and maintenance mechanisms that would be absent in a continuous exposure to food,” de Cabo added.
For the study, published in the journal Cell Metabolism, the team randomly divided 292 male mice into two diet groups.
The first group of mice had access to food round the clock. The second group of mice was fed 30 percent fewer calories per day than the first group. The third group was meal fed, getting a single meal that added up to the exact number of calories as the round-the-clock group.
“This study showed that mice who ate one meal per day, and thus had the longest fasting period, seemed to have a longer lifespan and better outcomes for common age-related liver disease and metabolic disorders,” said Richard J. Hodes, Director at the NIH.
“These intriguing results in an animal model show that the interplay of total caloric intake and the length of feeding and fasting periods deserves a closer look,” he noted.
The findings may encourage future studies on how these types of time-restricted eating patterns might help humans to maintain healthy weight and reduce some common age-related metabolic disorders.
Fruit and Vegetable Juices That Enhance the Immune System
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:
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.
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.
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.
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.
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.
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.
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
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.
