The Power of Nitric Oxide: Benefits and Nitrate-Rich Foods

What is Nitric Oxide?

Nitric Oxide (NO) is an important gaseous signalling molecule that plays an integral part in many physiological processes within the human body.

Chemically speaking, NO is an extremely simple molecule consisting of one nitrogen and one oxygen atom with its formula being NO. Due to this structure, NO can easily diffuse across cell membranes and influence various biochemical pathways.

The production of nitric oxide occurs through an enzyme family known as Nitric Oxide Synthases (NOS).

These enzymes convert L-arginine into nitric oxide while simultaneously producing L-citrulline.

Nitric oxide synthases come in three primary isoforms, known as:

• Endothelial NOS (eNOS),

• Neuronal NOS (nNOS), and

• Inducible NOS (iNOS).

Each one serves a distinct function and may be expressed across multiple tissues.

Endothelial NOS plays an essential role in blood vessel health as its production of nitric oxide leads to vasodilation (the relaxation of vascular smooth muscle) and increased blood flow with lower blood pressure.

Nitric oxide plays an integral part in both cardiovascular and nervous systems, modulating neurotransmission and communication among neurons as well as modulating synaptic plasticity which is vital for learning and memory formation.

Nitric oxide also plays an integral part of our immune systems; produced by immune cells to fight pathogens and regulate inflammation processes.

Furthermore, due to its many uses, nitric oxide plays an integral role in maintaining homeostasis and optimal physiological functioning within the body.

This molecule's ability to control multiple processes exemplifies its significance for health and disease, making it a significant area of scientific inquiry.

The Benefits of Nitric Oxide for Running

Nitric oxide (NO) has gained significant traction within the fitness world due to its multitude of health benefits, especially related to cardiovascular health.

Nitric oxide's primary benefit lies in its ability to stimulate better blood flow.

By relaxing the blood vessels, NO can assist with vasodilation and facilitate an increase in circulation, leading to better oxygen and nutrient transport across various tissues in your body - thus supporting overall wellness.

Nitric oxide has also been linked with lower blood pressure.

Research indicates that nitric oxide's vasodilatory effect can reduce resistance in blood vessels and thus ease their workload on the heart, therefore decreasing the workload.

Individuals living with hypertension or at risk for cardiovascular diseases will especially find this to their advantage.

Nitric oxide offers another key benefit - improving exercise performance. As athletes frequently search for ways to increase endurance and strength, nitric oxide shows positive results in the published data.

These studies indicate that adequate levels of nitric oxide may help enhance oxygen utilization during physical activity and enable longer sustained efforts and quicker post-exercise recoveries.

Nitric oxide also assists with recovery by relieving muscle soreness and speeding the repair of tissues damaged during strenuous activities. In addition, it has anti-inflammatory properties. By decreasing inflammation in the body, nitric oxide may protect from various chronic illnesses.

Nitric oxide's numerous benefits, supported by scientific research and expert opinions, emphasise its significance in improving not only cardiovascular health but also physical performance that is accessible for everyone.

Nitric Oxide Mechanisms

Nitric oxide is produced through complex biochemical pathways in our bodies by converting certain foods containing nitrates to nitric oxide.

Beginning in the mouth, bacteria convert nitrates to nitrites which then undergo further degradation by stomach acids into nitric oxide.

The upper gastrointestinal tract absorbs dietary nitrates, resulting in high circulating nitrate levels.

About 25% of circulating nitrates are taken up by salivary glands, where they are then converted into nitrites by nitrate reductases produced by bacteria in the mouth.

The stomach protonates some of the nitrite that is formed in the mouth to create HNO 2. This then decomposes into NO.

The remaining nitrates are absorbed from the upper gastrointestinal system where they mix up with the nitrates that have been formed by the body.

There are several pathways in the circulation by which nitrites may also be converted to NO, including deoxyhaemoglobin or cytochrome P450.

As explained, nitric oxide serves to regulate both blood flow and pressure by relaxing blood vessels, or vasodilation. This vasodilation is key for controlling both flow and pressure.

When stimulated, endothelial cells lining blood vessels release nitric oxide which diffuses into smooth muscle cells of blood vessels and then into other areas.

There, it activates the guanylate cyclase enzyme, leading to an increase in levels of cyclic guanosine monophosphate (cGMP).

Accumulated cGMP induces relaxation of smooth muscles, leading to dilation of blood vessels and improved blood flow while decreasing resistance in vascularized regions.

As a result, nitric oxide is essential in improving blood flow, not only by providing oxygen and nutrients directly to different tissues but also by clearing away metabolic waste products from these tissues.

This effect can significantly boost athletic performance as adequate blood flow facilitates oxygen delivery to muscles during physical exertion.

Nitric oxide's role extends far beyond muscle contraction and endurance; it plays an integral part in improving exercise performance by optimizing oxygen supply and encouraging glucose uptake within muscle cells.

Understanding how nitric oxide functions within the body illustrates its significant contributions to cardiovascular health and athletic performance, underscoring its vitality as an essential molecule.

Top Foods High in Nitrates

As we can see, a diet rich in nitrate-rich foods can boost overall health and exercise performance.

Though receiving less recognition than beetroot juice, green leafy vegetables that contain high concentrations of nitrate have demonstrated promising blood pressure-reducing and endothelial functioning-improving benefits among healthy adults.

Vegetables that are high in nitrates include spinach (as used in beEnergy) and lettuce as well as other green leafy veggies such as fennel, rocket, radishes, Chinese cabbage and parsley.

The leafy vegetables contain more than just nitrates; they also offer various other vitamins, nutrients, and phytochemicals such as C, E and K vitamins, carotenoids (lutein and beta-carotene), flavonols (quercetin and kaempferol) folate, iron zinc calcium magnesium.

All of these nutrients are great for athletes as they are more susceptible to nutrient deficiencies as their bodies have a higher nutrient turnover: whereby their bodies have a higher rate of nutritional demand.

According to a recent review, six studies have demonstrated inverse associations between the consumption of leafy greens (primarily spinach and lettuce) and cardiovascular disease.

The vegetables with the highest concentrations of nitrates per 100g of fresh weight in a sample published by The American Journal of Clinical Nutrition were spinach (740mg/100g), collards greens (320mg/100g), mustard greens (12mg/100g), broccoli (40mg/100g) and tomato (39mg/100g).

The nitrate concentrations in banana, apple sauce and oranges were respectively 5 and 0,009, 0.3 and 0,08, and 8 and 0.015%.

The nitrate/nitrite content of vegetable and fruit juices was 27.6 mg/L (carrot juice), 26.9 mg/L (V8 juice), 12.9 mg/L (pomegranate), 9.1 mg/L (cranberry), and 0.6 mg/L (acai).

Incorporating Nitrate-Rich Foods into Your Diet

I would start with meal prepping as an effective means of including more nitrate-rich options in your week.

Prepare a nutritious salad featuring arugula or spinach mixed with other nutrient-rich ingredients like berries and nuts for a quick meal to go.

Beetroot can also be cooked in bulk for use throughout the week in various dishes like soup or grain bowls. Roasted beets make a tasty addition to quinoa salad.

Snacks can also help to boost your nitrate intake. Enjoy raw vegetables like celery sticks with hummus for extra flavour and nutrition!

An afternoon boost is available through a smoothie made of leafy greens and beet juice.

Utilizing these strategies and suggestions in your diet will allow you to easily increase the consumption of foods high in nitrates, thus improving health and increasing nitric oxide production in your body.
