There are numerous individuals across the globe who advocate for coffee consumption, yet there are also those who deny the benefits associated with its ingestion. While certain individuals extol the wonderful properties of coffee, others challenge everything that is associated with it. Nevertheless, coffee remains a favored subject for many debates. Should we even contemplate whether it is worth consuming?
Coffee and its impact on the responsiveness of cells to insulin
The ability of muscle, fat, and liver cells to respond to insulin is referred to as their insulin sensitivity. The greater the capacity to respond to insulin, the better the hormone can regulate blood glucose levels in the body and distribute them appropriately among cells, ensuring proper functioning. Coffee contains a substantial amount of polyphenols, particularly chlorogenic acid, which have antioxidant properties, enhance cellular insulin sensitivity, and inhibit the development of type 2 diabetes. Chlorogenic acid might slow down glucose absorption in the digestive tract, leading to improved insulin sensitivity. Additionally, coffee has anti-inflammatory properties that can protect against type 2 diabetes. Coffee consumption reduces the level of pro-inflammatory interleukin 18 in the body, which is recognized as a risk factor for the development of diabetes. Studies have shown that drinking coffee in individuals of normal body weight can improve cellular insulin sensitivity and reduce the risk of developing type 2 diabetes. However, the exact mechanism of action of coffee in this regard requires further investigation.
It's coronary artery disease
It is not possible to definitively state that atherosclerosis is directly linked to diabetes, although they often occur together. Coffee consumption may also be associated with an increase in homocysteine levels in the blood, which increases the risk of cardiovascular disease. However, coffee also contains polyphenols, which are known for their antioxidant properties and may help prevent the development of diabetes. It is also important to consider the type of coffee and the method of brewing, as unfiltered coffee may be responsible for an increase in homocysteine and LDL cholesterol levels compared to filtered coffee.
Arterial tension of His
The most hotly debated topic in the context of coffee is its impact on arterial tension. Coffee does not increase the likelihood of hypertension in healthy and physically active individuals. Coffee elevates arterial tension, albeit as a transient effect, resulting from heightened cardiac activity, expanded excretory capacity, and increased vascular resistance. Those diagnosed with hypertension should exercise caution when consuming coffee, but they do not need to abstain from it. Research indicates that consuming 1-3 cups of coffee daily reduces the risk of mortality from heart diseases. It has been proven that the increase in arterial tension immediately after coffee consumption is higher in individuals who do not regularly drink coffee.
An awakening moment
The task of caffeine and its metabolites, such as theophylline and theobromine, is to activate dopamine receptors, leading to stimulation of the central nervous system and cerebral cortex, and an increase in the release of mediators such as serotonin, GABA, adrenaline and noradrenaline. This stimulation results in increased concentration and improvement of mood. In today's times, where the pace of life requires us to engage more and be more productive from the morning, caffeine plays a very important role. Coffee can also assist drivers by helping to combat the feeling of drowsiness. Studies show that drivers who have consumed caffeine show more concentration and focus than those who have not consumed coffee. However, it is important to note that excessive caffeine consumption can lead to overstimulation, increased diuresis, and tachycardia. Coffee assists athletes by increasing insulin sensitivity and accelerating metabolism. This is achieved through increased thermogenesis and increased oxidation of fatty acids. Additionally, caffeine helps prevent muscle fatigue by accelerating the regeneration of glycogen stores.
Coffee during pregnancy: a key question and answer
Can a pregnant woman consume coffee? A question that requires an answer. Research indicates that one can, but also cannot. It has been found that women who consume larger amounts of coffee have an increased risk of miscarriage. However, if the caffeine dose is appropriate (up to 300 mg), coffee consumption by pregnant women is considered acceptable. It is important to maintain the daily average balance of caffeine and its analogues (such as theine in tea or mateine in yerba mate).
Healthful Benefits of Coffee Consumption
It appears that the healthful benefits of coffee consumption far outweigh any potential drawbacks. There are no restrictions on consuming coffee, and it is sometimes even recommended due to its flavorful and healthful properties. However, it is always important to bear in mind that excess can be harmful. For individuals with digestive issues, coffee may not be recommended as it stimulates the production of gastric acid, which can act as an irritant to membranes, and reduces the pressure of the lower esophageal sphincter, which may exacerbate the symptoms of gastroesophageal reflux disease.
