Beet juice consumed before workout increases brain performance

Many studies have so far confirmed that regular physical activity can have a positive effect on the functioning of our brain. This relationship is particularly noticeable especially in the elderly, when, together with age we suffer from weakness of brain function. According to recent research, it is possible to strengthen the exercises effects on the brain by drinking beet juice before taking the physical activity of moderate intensity.

Researchers studying this interesting relationship suggest that drinking beetroot juice may help improve brain function especially in older people, but drinking it earlier helps our brain for the future.

As is evident from the findings of scientists, the older adults, who consume beet juice before a moderately intense workout, have better connectivity in brain regions that are associated with motor functions, compared to individuals who do not drink beet juice before exercise.

The research team from the Department of Health and Exercise at Wake Forest University in Winston-Salem, North Carolina W. Jack Rejeski at the helm, notes that increased brain connectivity among adults who drink beet juice is comparable with connectivity that is noticeable in people that are much younger.

Beets are root plants, which are known for their wide variety of properties and applications. Their popularity has been fueled by potential health benefits including the ability to lower blood pressure and increase productivity during physical activity. Their ruby juice delights with taste and is a valuable source of vitamins, minerals, and antioxidants.

Many of the benefits associated with the consumption of beets, is attributed to the high content of nitrates. When ingested, they are converted into nitric oxide, which, as demonstrated by the study, lowers blood pressure and increases blood flow to the brain.

Many previous studies indicated that exercise has an excellent effect on the brain so in their scientific tests Rejeski and his team decided to examine whether the beet juice can increase the benefits of physical activity in our brain.

Beetroot juice strengthens the cerebral cortex

A study conducted by researchers from the Department of Health and Exercise at Wake Forest University in Winston-Salem, North Carolina, included 26 participants aged 55 years and over, who suffered from high blood pressure. None of the participants exercised regularly, and most of them consumed two different types of blood pressure lowering drugs.

Each test participant had to participate in a 50-minute moderate treadmill exercise three times a week for six weeks. An hour before the practice session, one group of participants consumed the beetroot juice containing 560 milligrams of nitrates, while the others drank a placebo beverage low in nitrates.

After six weeks, researchers investigated the brain function of individual participants using MRI.

As tests have shown, people who received beet juice before exercise, have a structurally reinforced cortex – the region, in particular, that help to control body movements and motor skills, as opposed to those consuming a placebo, who showed no difference.

Interestingly, people who used the only supplement of beet juice also showed greater connectivity between brain regions, in particular, responsible for cognition, emotion, and the like. As the researchers noted leader of the study, the activity of brain connections, is usually visible at similar levels in people at much younger age.

The cerebral cortex during exercise receives and processes signals from muscles, and beet juice enhances this effect by converting nitrate to nitric oxide delivering more oxygen to the brain.

Nitric oxide is a powerful molecule that allows hypoxic areas in need of oxygen or that need to gain an extra dose of this treasured component, and the brain is one of the sphere of the body most in need of it.

As scientists say, it will be necessary to carry out much more additional research on this subject, but as it is shown by the tests already, what we consume every day, has a very significant impact on our health in the future. Consumption of beet juice can, therefore, play an imperative role for our health and mobility of the brain in old age.

Many studies are highlighting the positive impact of exercise on the brain, especially in people suffering from hypertension, and now they can be modified by an element associated with the consumption of beet juice. Increased connectivity in the brain that can be gained through this ruby vegetables enables us to rejuvenate the brain, effectively preventing the weakening of its essential functions.

Olive oil can help reverse the damage associated with a high-fat diet

Benefits which carries virgin olive oil are known not from today. As it turns out, in addition to the more familiar advantages of this great vegetable fat, it has less known biological and physiological mechanisms that act on our body extremely positively. According to recent studies, a compound which contains a virgin olive oil can reverse the adverse effects posed by a diet high in fat.

According to a survey carried out on mice, virgin olive oil may reverse symptoms of the nonalcoholic liver disease.

Previous research has shown that olive oil, and especially virgin olive oil, can reduce the risk of cardiovascular diseases. Unfortunately, researchers have not found too many details on the mechanisms responsible for this significant relationship between olive oil and health benefits the cardiovascular system.

To explore this mystery, a team led by Dr. Rodrigo Valenzuela of the University of Chile in South America decided to investigate how the compound contained in virgin olive oil affects the health of mice.

The compound in question is hydroxytyrosol polyphenol with rich antioxidant properties, which combines the numerous health benefits associated with the consumption of olive oil.

Hydroxytyrosol – a compound contained in olive oil can have a protective effect on the liver.

The research team studied the effects of hydroxytyrosol on mice that were fed a diet rich in fats. In particular, certain enzymes have been considered that play a significant role in the synthesis of some polyunsaturated fatty acids.

Polyunsaturated fatty acids are beneficial to health since they help reduce the “bad” cholesterol, improve the health of the cardiovascular system, brain function and affect cell growth.

The so-called “bad” cholesterol, is known as low-density lipoprotein cholesterol – LDL. It is called “bad” cholesterol because it is a type of fat that often accumulates inside the arteries, and curing and blistering for a long time can cause numerous cardiovascular diseases.

High-density lipoprotein cholesterol – called “good,” in turn, transports cholesterol from other parts of the body to the liver, where it is processed and eliminated.

During the test, researchers from the University of Chile in South America were feeding four groups mice (each having 12 to 14 subjects rodents) using a high-fat diet (60% fat) or a control diet (10% fat). Also, some mice were treated with 5 mg hydroxytyrosol per kilogram body weight. The tests lasted 12 weeks.

Obtained by a team of researchers blood and tissues of the mice at the end of the experiment showed an interesting relationship. In studies, the scientist has analyzed the effect of diet on fatty acid composition, enzyme activity, and oxidative stress.

Hydroxytyrosol reverses the symptoms of the fatty liver disease.

In mice that were fed a high-fat diet, total cholesterol, and LDL increased, while HDL was maintained at a similar level. However, the addition of hydroxytyrosol in the diet seemed to reduce the negative impact of these types of cholesterol on the mice that took it.

A high-fat diet also appeared to increase insulin resistance markers, but those of the mice who were administered with the compound of olive oil, these markers were reduced. But they were not as low as in the mice consuming it regularly.

Importantly, mice with high-fat diets showed reduced levels of liver enzymes that helped synthesize polyunsaturated fatty acids. Decreased liver enzyme activity was associated with an imbalance of fatty acids in the liver, brain, and heart.

Mice whose diet has been enriched with hydroxytyrosol have shown enzymatic activity and a fatty acid composition similar to that obtained through the use of a regular diet. This may mean that the diet rich in olive oil can reverse the harmful effects of a high-fat diet.

The results seem to indicate that hydroxytyrosol could be a key element of the health benefits of olive oil extra virgin.

Mice fed a diet high in the fat, exhibit the symptoms of the non-alcoholic liver disease, which is combined with a noticeable reduction in the enzyme activity in the liver and the adverse effects of the fatty acid and organs. Similarly, oxidative stress associated with liver disease is also increased. But, as scientists say, promising research results, the use of regular doses of hydroxytyrosol in the diet can divert all these adverse effects, reduce the symptoms of liver disease and limit the negative effects seen in other organs.

Why in some cases exercises do not work?

Regular physical activities are considered as an essential element, supporting the prevention of obesity and related to extracurricular pounds health conditions. As it turns out, some of us derive much greater benefit from regular exercises than others. Recent studies seem to know the answer to the question why is this happening.

According to recent findings based on research in both mice and humans, higher levels of selenoprotein P – the protein secreted by the liver, might cause the less dynamic exercise effects and, consequently, limited benefits associated with the regular physical activity.

These studies were conducted by researchers from the Canadian College of Medical Sciences, Kanazawa.

Studies suggest that selenoprotein P can cause resistance to physical effort.

Current guidelines recommend that adults should practice an average of about 150 minutes deciding on the aerobic activity of moderate intensity or 75 minutes of intense activity a week because this amount will allow remaining healthy.

However, depending on the person, the response to exercise – both regarding strength and metabolic health, may be entirely different. Some people do not feel any results despite regular aerobic exercise. Similar relationships show that 15-20 percent of individuals who have type 2 diabetes, where, despite performing a routine physical activity, hypoglycemia does not show appropriate changes.

Recent discoveries show that some of us suffer from resistance to exercise, and therefore have limited opportunities to benefit from the regular physical activity.

The precise mechanisms of resistance on exercises have not been clear, but recent studies indicate that selenoprotein P may play a significant role in this relationship, which is why scientists from the Canadian College of Medical Sciences, Kanazawa undertook further study of this compound.

During the tests, the team assessed the effects of physical exercise on two groups of mice – some of them had a deficiency in selenoprotein P, and the other part of them was a randomized control group. Both groups ran on the treadmill for 30 minutes a day for one month. Researchers have found that those of the mice that were free of selenoprotein P had double exercise capacity as those in compared control group.

Interestingly, the mice exhibiting a limited amount of selenoprotein P at the end of the month-long test had reduced the blood glucose level after the injection of the insulin hormone.

It should also be noted that the control group of mice before the month of treadmill training, received an additional dose of selenoprotein P. Rodents in this group have shown, among other things, a reduction in the AMPK enzyme phosphorylation in muscle tissue, and as the scientists explain – AMPK phosphorylation is strongly linked to the many benefits that regular exercises can give to us.

Besides, the researchers showed that mice lacking LRP1 – selenoprotein P receptor in muscle, could not absorb the selenoprotein P into the muscles, and phosphorylation of AMPK hasn’t got any influence on their effectiveness on the exercise.

Conclusions from the study may support the discovery of medicines that stimulate the benefits of exercise.

A team of researchers from the Canadian College of Medical Sciences in Kanazawa took up further studies to demonstrate how the selenoprotein P may affect the effectiveness of exercise in humans.

Therefore, 31 healthy women who did not train regularly were subjected to the study. All women participated in aerobic training during the eight-week period, and their maximum oxygen uptake during exercise was monitored throughout the period to determine their exercise tolerance during exercise.

The team found that women with high levels of selenoprotein P in the blood before the start of the 8-week study showed lower maximal oxygen intake compared to those with lower levels of selenoprotein P. Researchers believe that this liver-induced protein promotes exercise by targeting the LRP1 receptor on the muscles.

Further studies are needed to obtain more detailed information on the effects of selenoprotein P on physical activity, but the team agrees that this study may pave the way for the development of medications that will help to reduce the production of selenoprotein P to increase exercise endurance.

So far, the present findings suggest that future screening for inhibitors axis (selenoprotein P) – LRP1 can help develop stimulant medication effort to treat diseases associated with a lack of physical activity, such as type 2 diabetes.
