" Ascorbic acid " Vitamin C has too many benefits
A natural whitening and skin care ingredient , together with other vitamins synergistic antioxidant (Related reading: When eating vitamin C, the effect is doubled, and the synergistic effect of antioxidants is synergistic.) , beneficial to bone health (a nutrition that is very important for bone density, which is ignored by many people, not calcium.) , assists the body to absorb and store iron.
helps treat scurvy, oral ulcers, bleeding gums; resists viruses and relieves severe illness ; (Related reading: Who is the most likely to get sick, aging, lack of vitamin C? The answer is it.) reduces inflammation, fights oxidative stress , etc. ( Related reading: Latest research: Frequent fire and toothache may be the culprit of hypertension .)
So, what population needs to supplement vitamin C?
There are many studies that people with heart problems actually need to supplement vitamin C more to help repair collagen , heal blood vessel damage, reduce oxidative stress levels, and reduce the risk of heart disease .
In this article today, let’s talk about the relationship between vitamin C and heart health↓
The arterial inner wall damage forms plaques, causing heart disease
First of all, let’s talk about something that subverts your views: the murderer of heart disease has someone else, not cholesterol . ↓
A study analyzed data published in 2012 in the late 1960s and early 1970s. It was found that removing saturated fat from safflower oil and increasing polyunsaturated fat can effectively reduce cholesterol levels , but will cause a 62% increase in subjects' all-cause mortality rate.
In addition, this large-scale study from the late 1960s and early 1970s found that although reducing saturated fat will lead to a decrease in cholesterol, this effect not only cannot reduce cardiovascular risk, but will increase all-cause mortality.
results part of the study showed that "There was a 22% higher risk of death for each 30 mg/dL (0.78 mmol/L) , and the risk of death for each 30 mg/dL (0.78 mmol/L) reduction in serum cholesterol.”
Why is cholesterol lowered and the risk of death higher? Here is the reason behind it.
→Damage to the blood vessel wall, causing plate
So, fundamentally speaking, what causes heart disease?
In addition to genetic factors, poor eating habits, and indirect effects of some dangerous behavioral factors lead to obesity and overweight, further increasing the risk of heart disease.
In fact, factual evidence has found that damage to the inner wall of the artery vessels will cause plaques to form in the blood vessels, leading to arteriosclerosis, blocking blood flow, and increases the risk of heart disease.
First, if the skin is cut, will form clot .If the artery is damaged, the same coagulation cascade will be initiated, and the wound will be scabbed, and then it will heal to form new skin.
However, if the scab skin is peeled off before it has healed, it will re-initiate the coagulation cascade, resulting in more swelling and larger clots, accelerates the progression of cardiac plaques, and narrowing of the arteries (stenosis), further causing arteriosclerosis.
and in turn, atherosclerosis can cause blood vessel blockage, which can cause heart attacks and strokes .
cholesterol in plaques is cholesterol crystals, which comes from red blood cells , further indicating that the plaque forms thrombus, which is the real cause of cardiovascular disease.
→Causes of arterial inner wall damage
causes damage to the arterial inner wall, generally may include:
High sugar diet causes High blood sugar , high inflammation , smoke or long-term exposure to excessively contaminated air , heavy metal toxicity exposure, cortisol levels, long-term chronic stress, leading to insulin resistance.
So, the "cholesterol hypothesis" and is not the real cause of heart disease . ( related reading: "Cholesterol", the biggest unjust case on Nutrition , is even more unjust than Dou E ....)
What is the relationship between supplementing vitamin C and it? .
Vitamin C synthesizes collagen, repairs blood vessels
→Vitamin C helps blood vessels repair
Research has found that collagen is the basis of the skin - it is also the main substance that constitutes blood vessels , and vitamin C helps increase protein collagen produces , which is exactly necessary for repairing collagen.
Therefore, when vitamin C is sufficient, , body will be more likely to repair various collagen damage, including repairing damage to blood vessels.
If the vitamin C level in blood vessel cells is too low to complete the repair of vascular collagen, the main component in the plaque cholesterol crystal Lp(a) will act as a substitute, captures amino acid exposed to the endothelial lining due to collagen damage, and starts the coagulation process .
When the blood vessel is damaged, the binding site previously buried in collagen will suddenly be exposed, binding to cholesterol (including Lp(a)) passing through the bloodstream, thus starting to form clots.
Then this process will absorb various substances and form clot matrix , including red blood cells and platelet .
Patients with higher levels of Lp(a) face greater risks of endothelial injury during this process, resulting in an increased risk of heart disease.
and sufficient vitamin C can help repair blood vessel damage.
In addition, in 2016, a epidemiological survey found that when the human body lacks vitamin C, it will lead to an increase in the risk of cardiovascular disease.
Deficiency of vitamin C, and the risk of cardiovascular disease is increased
2016, a study published in Int J Mol Sci. International Journal of Molecular Science found that vitamin C deficiency is related to a higher risk of death from cardiovascular disease (CVD).
It is known that vitamin C can inhibit LDL protein oxidation , thereby reducing atherosclerosis;
This research review covers the impact of vitamin C on cardiovascular in human studies.
The two most famous cohort studies that study the connection between vitamin C and CVD are HPFS and NHS:
NHS cohort study, more than 121,000 women in were followed up for 16 years.Dietary data were collected from the Food Frequency Questionnaire (FFQ) conducted at baseline and then performed every two to four years. This study found that there was a moderate negative correlation between the subjects' vitamin C intake and the risk of coronary heart disease .
Overall, these meta-analysis showed that vitamin C supplementation can improve vascular endothelial function and lower blood pressure . vitamin C and antioxidant vitamin E can also reduce arterial stiffness.
These meta-analysis of various components of heart disease risk provide evidence for possible mechanisms in which vitamin C may be associated with heart disease.
The key skin dragon says that
has many effects. It is a powerful antioxidant. Many literatures have recorded about vitamin C2 reducing the risk of heart disease .
is not only antioxidant, but also synthesizes collagen to repair blood vessel damage and prevent LDL from being oxidized by .
In addition, vitamin C has the effect of improving blood lipids , arterial stiffness and endothelial function.
Vitamin C is very important for immune function, and is particularly important for collagen synthesis, bone health, and resistance to free radical .
Generally speaking, there is no problem with vitamin C of about 2000mg for ordinary people. If you are particularly lacking, older people and severely ill patients, you can consume more vitamin C under the guidance of professionals.
You can adjust it based on this recommended value and your actual physical condition.
