A study published in the journal Cell Metabolism found that participants who took small daily doses of inorganic nitrates experienced an improvement in the function of their mitochondria, the organelles that provide energy for human cells.

This allowed them to use less oxygen with each breath while riding an exercise bicycle.

Nitrate has long been considered of little value to the human body. In large doses it is toxic, and it can be found as an oxidizer in airbag propellants, solid rocket fuel and fireworks. However, previous studies have suggested nitric oxide, a compound derived from nitrates, may help blood vessels dilate, which relieves high blood pressure.

Researchers noted that the amount of nitrate needed to produce the mitochondrial effect was no more than may be found in spinach, beets and certain other vegetables.

They concluded that eating spinach may not only help improve heart health but contribute to muscle function as well.

Spinach is also a rich source of iron, calcium, lutein and antioxidants, according to the Centers for Disease Control and Prevention.

How do you know you are getting the most absorbable form of CoQ10? Let’s examine the methods of production and see which one has been shown to be most effective.

If your supplement is powder form, then you may not be getting the full benefits of CoQ10. Laboratory studies show that up to 99 percent of powder CoQ10 is not absorbed in your body. If your supplement is liquid form, then it may contain crystallized molecules formed in the heating and cooling process of manufacturing. These microscopic molecules can’t easily be absorbed so you’re not getting ample CoQ10 in this form, either. If your supplement doesn’t contain healthy fats, then you can’t absorb CoQ10. This nutrient needs fat to be absorbed into your bloodstream.

To get the most effective CoQ10, you should find a quality supplement that contains vitamins and healthy fats for optimum absorption. With this energy-boosting nutrient, you can help strengthen and protect your heart… prevent serious brain events… boost healthy circulation… stabilize and regulate your heartbeats… and more.

The research indicates that being physically active is an important lifestyle choice a person can make in order to improve their health. Leslie Alford, the study's lead author, said that individuals have control over some of the factors that contribute to how healthy they are, and this includes exercise.

Among physical activity benefits that the research highlights is that regular intense workouts can help to decrease the risk of coronary heart disease, as well as some types of stroke. Increasing the amount of exercise can also help to reduce the risk of some cancers, depression, obesity and high blood pressure.

The study also noted that physical activity is associated with a decreased risk of developing memory loss problems.

Alford suggested that for those who need to increase their levels of exercise, healthy adults could participate in a 30-minute brisk walk five days each week and that older adults could benefit from physical activities that focus on flexibility and balance.

While exercise could lead to a healthier lifestyle, only about 25 percent of the nation's population participates in physical activities, according to the Centers for Disease Control and Prevention (CDC).

Prior research has resulted in this compound improving liver and pancreatic health in mice. For this study, a team of researchers analyzed more than 19,000 molecules, including the bile acid, to determine the anti-aging effects of LCA.

The investigators discovered that regardless of one's daily caloric intake, the yeast longevity was improved by the bile acid. Furthermore, the results showed that during caloric restriction and stressor protein activity, the life-extending process continued to function properly.

"This leads us to believe that bile acids have potential as pharmaceutical agents for the treatment of diabetes, obesity and various metabolic disorders, all of which are age-related," said Alexander Titorenko, lead author of the study. He added that "they may indeed offer hope for a healthy aging life."

In addition to the longevity benefits of bile acid, taking natural supplements containing resveratrol, a powerful antioxidant, can help slow the signs of aging.

For this trial, a total of 62 older individuals were surveyed about their sleeping habits. As a result, the researchers found that while participants reported exhaustion during the day, they chose to avoid napping because they considered it lazy.

Also, in order to consistently sleep through the night, the individuals said they reduced their fluid intake throughout the day. Furthermore, many participants said they avoided seeing their doctors about sleeping problems because they didn't want to take sleeping medications.

Based on these findings, the team suggests that napping in the afternoon would prove beneficial for older people. By taking a short nap each day, the rest would allow them to be more energized and be able to function better throughout the day.

"Sleep is central to health and well-being, but as people get older, the quality of their sleep can deteriorate," said Susan Venn, lead author of the study. She added that "many older people are prescribed medications to help them sleep, but research has shown that sleeping medication may impact on the lives of older people."

Each year, approximately 70 million Americans are diagnosed with sleeping problems, according to the Centers for Disease Control and Prevention.

Prior research has shown that the use of a standard caloric calculation could lead to better weight gain and overall quality of life among those with the breathing disorder. In an effort to improve these people's energy levels during the day, a team of researchers altered the caloric calculation and treated a total 86 COPD patients with an average age of 64 years.

The researchers discovered that by enhancing the previous method, physicians may be able to determine a more accurate energy requirement for their patients, resulting in more specific caloric count and healthy weight gain.

Frode Slinde, lead author of the research, stated that "a better nutritional status has been linked with patients feeling better and not needing as much care as before, which could cut the cost of care to society in the long run." He added that "as far as COPD patients are concerned, a better nutritional status translates into better quality of life and a longer life."

According to the Centers for Disease Control and Prevention, approximately 190,000 Americans residing in nursing homes have been diagnosed with COPD.

In an effort to better understand how physical activity may improve joint and muscle pain among adolescents, researchers enrolled 104 individuals aged 11 to 18 years in a one-week trial. Participants wore actigraphs, a device that records each individual's physical activity levels.

The researchers discovered that one study participant exercised for 60 minutes per day, while approximately 23 percent of these individuals were active 30 minutes per day.

The team discovered that the most active adolescents were in less pain, and experienced fewer symptoms including depression and irregular sleep patters. However, the inactive participants slept poorly, and were in more pain and more depressed.

While increasing one's physical activity proved beneficial for young fibromyalgia patients, investigators suggested that further research will be needed to determine the long-term effects of regular exercising.

In addition to increased physical activity, other natural alternatives for fibromyalgia pain relief include acupuncture, therapeutic message and chiropractic treatments, according to the National Fibromyalgia Association.

During a recent study, researchers observed how delaying morning classes by 30 minutes would affect more than 200 high school students. Following the time change, participants were asked to complete an online survey about how they felt before and after the delay start time of their school days.

Students reported that following the time change, they were more motivated and slept better during the week. Also, results of the surveys showed that individuals were less fatigued, drowsy and experienced less signs of depression.

Furthermore, the number of students who were sleeping at least eight hours per night increased from 16.4 to 54.7 percent, while individuals who averaged less than seven hours of sleep decreased by 79.4 percent.

Kyla Wahlstrom, a researcher at the University of Minnesota, stated that "teenagers need and deserve [the] best informed thinking about all of this, [and] having the facts in hand is the best place to start." She added that later start times may lead to "several significant academic effects, such as decreasing the dropout rate, but a direct correlation between later start time and academic achievement on normed tests has not been substantiated."

According to the Centers for Disease Control and Prevention, adolescents need approximately 8 1/2 to 9 hours of sleep per night.
