A Nitrate Rich Diet is Good for Heart Health
Our diet is an important, it is a Key factor for the maintenance of a healthy heart well into old age.
Healthy dietary fats Top the list of heart-healthy foods, but aside from that, a nitrate-rich diet can go a long way toward protecting the heart.
Nitrates should not be confused with nitrites, found in bacon, hot dogs, ham and other less-than-healthy cured meats.
Nitrites can convert into potentially dangerous nitrosamines, especially if heated, which is why processed meats are best avoided.
In fact, after examining over 7,000 clinical studies, the World Cancer Research Fund concluded there is no safe lower limit for processed meats, and they should be avoided.
On the other hand, many vegetables contain naturally occurring nitrates.
When consumed, the bacteria in your mouth convert these nitrates to nitrites, but since vegetables are also rich in antioxidants, these nitrites do not pose a health hazard.
More importantly, the human body transforms the nitrates in vegetables into nitric oxide (NO), a soluble gas continually produced from the amino acid L-arginine inside of our cells.
NO is a gas and free radical that is an important biological signaling molecule that supports normal endothelial function and protects the little powerhouses inside your cells, your mitochondria. Acting as a potent vasodilator, NO also helps relax and widen the diameter of your blood vessels, allowing a greater volume of blood to flow through.
Healthy blood flow helps the body function at its best, as our blood carries oxygen and nutrients to our heart, brain and other organs. It nourishes and oxygenizes your immune system and muscles, and helps keep your heart beating. It also carries away waste material and CO2 (carbon dioxide).
A diet high in nitrate is a natural strategy recommended for the treatment of prehypertension and hypertension (high blood pressure), “and to protect individuals at risk of adverse vascular events,” i.e., heart attacks.
Raw beets, high in nitrates, have been shown to lower blood pressure by an average of 5 points within a matter of hours.
Some studies have shown a glass of beet juice can lower systolic blood pressure by more than 8 points, far more than most blood pressure medications.
In conventional medicine, nitrates are used to treat angina and congestive heart failure, and research shows a glass of beetroot juice has the same effect as prescription nitrates.
In a recent study, patients diagnosed with high blood pressure who drank beet juice an hour before exercise, 3X a week for 6 weeks, experienced increased tissue oxygenation and blood flow. It also improved brain neuroplasticity by improving oxygenation of the somatomotor cortex.
NO is a vital biomolecule that “goes to the areas of the body which are hypoxic, or needing oxygen, and the brain is a heavy feeder of oxygen in our body. The heart requires NO and oxygen for optimal function.
As noted by cardiologist Dr. Stephen Sinatra: “Adequate NO production is the first step in a chain reaction that promotes healthy cardiovascular function, while insufficient NO triggers a cascade of destruction that eventually results in heart disease… NO promotes healthy dilation of the veins and arteries so blood can move throughout your body. Plus, it prevents red blood cells from sticking together to create dangerous clots and blockages.”
Leafy greens Top the list of nitrate-rich foods. Beets, which are a root vegetable, are well-known for their high nitrate content, but leafy greens contain even more nitrates per serving.
In fact, beets barely made it onto the Top 10 list, which is as follows:
1. Arugula, 480 mg of nitrates per 100 grams
2. Rhubarb, 281 mg
3. Cilantro, 247 mg
4. Butter leaf lettuce, 200 mg
5. Spring greens like mesclun mix, 188 mg
6. Basil, 183 mg
7. Beet greens, 177 mg
8. Oak leaf lettuce, 155 mg
9. Swiss chard, 151 mg
10. Red beets, 110 mg
Arugula,I eat is every day, is in the # 1 spot, contains more nitrates than any other vegetable, and by a wide margin too, 480 mg per 100 grams.
The 2nd-highest source, rhubarb, contains about 280 mg per 100 grams, which is about the same amount found in a 100-gram serving of beet root juice, whereas 100 grams of whole red beets provide a mere 110 mg of nitrates.
Other foods high in nitrates include the following.
Note: While garlic is low in nitrates, it helps boost NO production by increasing NOS, which converts L-arginine to NO in the presence of cofactors such as vitamins B2 and B3.)
Source Mg of nitrates per 100 grams
1. Bok choy 70 to 95 mg
2.Carrots 92 to 195 mg
3. Mustard greens 70 to 95 mg
4. Spinach 24 to 387 mg
5. Chinese cabbage 43 to 161 mg
6. Winter melon 16 to 136 mg
7. Eggplant 25 to 42 mg
8. Parsley 100 to 250 mg
9. Leeks 100 to 250 mg
10. Turnips 50 to 100 mg
11. Cauliflower 20 to 50 mg
12. Broccoli 20 to 50 mg
13. Artichoke Less than 20 mg
14. Garlic Less than 20 mg
15. Onion Less than 20 mg
Research has shown that the more vegetables and fresh fruits we eat, the lower the risk of heart disease, with leafy greens being the most protective. The reason for this is likely their NO-boosting nitrates.
This was confirmed in a May 2017 study published in The American Journal of Clinical Nutrition.
In this study, nearly 1,230 Australian seniors without atherosclerotic vascular disease (ASVD) or diabetes were followed for 15 years.
A food-frequency questionnaire was used to evaluate food intake, while nitrate intake was calculated using a comprehensive food database. As expected, the higher an individual’s vegetable nitrate intake, the lower their risk for both ASVD and all-cause mortality.
According to the study’s authors: “Nitrate intake from vegetables was inversely associated with ASVD mortality independent of lifestyle and cardiovascular disease risk factors in this population of older adult women without prevalent ASVD or diabetes. These results support the concept that nitrate-rich vegetables may reduce the risk of age-related ASVD mortality.”
Most competitive athletes understand the value of NO, and the wise ones take advantage of Mother Nature’s bounty.
While research has shown nitrate supplements can boost sports performance and enhance fast-twitch muscle fibers, you can get the same results using Real whole foods.
For example, research shows raw beets can increase exercise stamina by as much as 16%, an effect attributed to increased NO.
In another study, 9 patients diagnosed with heart failure who experienced loss of muscle strength and reduced ability to exercise were found to benefit from beet juice.
The patients were given 140 milliliters (mL) or 2/3rds cup of concentrated beet juice, followed by testing, which found an almost instantaneous increase in their muscle capacity by an average of 13%.
There’s one important caveat though: Avoid using mouthwashes or chewing gum, as this actually prevents the NO conversion from occurring. The reason for this is because the nitrate is converted into nitrite in your saliva by friendly bacteria. That nitrite is then converted into NO in other places in your body.
NO, not to be confused with nitrous oxide, commonly known as laughing gas, a chemical compound with the formula N2O25 serves as a signaling or messenger molecule in every cell of your body.
Hence, it’s involved in a wide variety of physiological and pathological processes, it causes arteries and bronchioles to expand, but it is also needed for communication between brain cells, and causes immune cells to kill bacteria and cancer cells.
The human body loses about 10% of its ability to make NO for every 10 years of life, which is why eating a nitrate-rich diet is so important. NO is further synthesized by nitric oxide synthase (NOS).
There are 3 isoforms of the NOS enzyme, they are, as follows:
- Endothelial (eNOS): a calcium-dependent signaling molecule that produces low levels of gas as a cell signaling molecule
- Neuronal (nNOS): a calcium-dependent signaling molecule that produces low levels of gas as a cell signaling molecule
- Inducible (immune system) (iNOS): calcium independent; produces large amounts of gas, which can be cytotoxic
Problematically, when fluoride is present (such as when you’re drinking fluoridated water), the fluoride converts NO into the toxic and destructive nitric acid.
As noted in “Pharmacology for Anesthetists 3,” “[NO] will react with fluorine, chlorine and bromine to form the XNO species, known as the nitrosyl halides, such as nitrosyl chloride.”
Hence, avoiding fluoridated water and other halide sources, such as brominated flour, is important to optimize your health and avoid damaging interactions.
Aside from eating a nitrate-rich diet, 1 efficient way to increase NO production is a series of callisthenic exercises.
I use a modified version of a routine originally developed by Dr. Zach Bush. This routine takes about 4 mins and is ideally done 3X a day, at least 2 hours apart.
