In this article,  Choose Supplement will explore this beverage with you and provide insights into whether or not coffee consumption has an impact on height

What is Caffeine?

Caffeine is a natural stimulant found in coffee, cocoa, and tea. It is well-known for its ability to help individuals stay awake and reduce fatigue by stimulating the brain and nervous system. Upon consumption, caffeine is rapidly absorbed from the intestines into the bloodstream, where it is transported to the liver and broken down into compounds that affect various organs in the body.

Caffeine primarily affects the brain by blocking the activity of adenosine, a neurotransmitter that induces relaxation. Adenosine levels in the brain increase as one gets drowsy, so when individuals consume caffeinated beverages that block adenosine activity, they become more alert. Caffeine also elevates blood adrenaline levels, promoting the activity of the neurotransmitters dopamine and norepinephrine.

These two primary actions of caffeine in the body stimulate the brain, resulting in a heightened state of alertness, focus, and euphoria. This is why caffeine is classified as a psychostimulant. The effects of caffeine are rapid, with individuals typically experiencing wakefulness within 20-60 minutes of consumption


Coffee Ingredients:

Coffee is a popular beverage that is made by roasting or grinding coffee beans. It is cherished for its unique taste that has an invigorating effect on individuals. There are various types of coffee available, each with a distinct taste that caters to the preferences of different individuals. Coffee comprises several compounds, including caffeine, antioxidants, and other substances that contribute to its unique flavor and well-documented physiological effects.

Caffeine: This is the primary substance in coffee, and its concentration varies between 1-3% depending on the coffee type and cultivation conditions.

Protein: Although the protein content in coffee is low, it plays a vital role in the coffee’s flavor formation process. Proteins containing amino acids such as cysteine, proline, and methionine are responsible for the aroma of coffee after roasting.

Antioxidants: Coffee contains substances such as chlorogenic acid and melanoidin, which have antioxidant properties.

Enzymes: Coffee beans have a high concentration of enzymes such as protease, β-glucosidase, and lipase that are involved in the production of amino and fatty acids.

Lipids: The lipid content in coffee varies depending on the type and location of cultivation. Coffee contains crude lipids such as oils and waxes, accounting for 10-13% of its composition. When brewed in hot water, a small quantity of lipid dissolves in water, while the rest accumulates in the grounds.

Minerals: Nitrogen, potassium, chlorine, phosphorus, iron, copper, and other minerals are present in coffee, accounting for approximately 3-5% of its composition.

Flavor Compounds: Coffee comprises a small quantity of flavor compounds, primarily located in the coffee beans. The aroma becomes more intense as the acreage of coffee grown increases

Can drinking coffee affect height growth?

While the impact may not be significant, several studies have suggested that caffeine consumption can reduce calcium absorption. Calcium deficiency can lead to weaker bones and hinder the growth process, which is especially concerning for children and adolescents who are still in the stage of physical development. Regularly drinking a lot of coffee can cause some loss of calcium, which is not beneficial for growth.

Moreover, other effects of coffee can contribute to a decrease in growth rate:

Disrupting sleep

Caffeine in coffee can increase energy and promote alertness, which can interfere with sleep if consumed near bedtime. Caffeine stays in the bodies of young people much longer than adults, making it important for teenagers to be cautious.

The strong effect of caffeine can make it difficult to fall asleep and cause restless sleep. A good night’s sleep is crucial for the growth process as during deep sleep, the body secretes a lot of growth hormone. Inadequate duration and quality of sleep can hinder growth.

Coffee can contain a lot of sugar

Certain coffee drinks can be high in added sugar in the form of syrups, ice cream, and other additives. Excessive sugar intake can reduce the body’s ability to absorb beneficial nutrients, leading to weight gain. Higher weight and excess fat can also put pressure on the bones and hinder their ability to grow and stretch.

What to consider when drinking coffee to avoid affecting height?



Drinking too much coffee can lead to negative effects on various parts of the body, including the bones, brain, respiratory and cardiovascular systems. Nutritionists advise that children aged 12-18 should not consume more than 100 mg of caffeine and that caffeine supplements should not be recommended for children under 12 years old. Therefore, children under 12 should avoid drinking coffee, while children over 12 can consume a small amount of coffee to stay awake for studying and work, but should avoid excessive consumption.

Time of consumption:

Drinking coffee in the afternoon or evening can cause difficulty falling asleep and disrupt sleep at night. Caffeine remains in the body for a long time, making the brain alert and affecting sleep quality. Drinking coffee before 2 PM and after meals can ensure that coffee only has the effect of maintaining alertness without affecting other activities during the day.

Type of coffee:

Choosing low-caffeine coffee is better for children and teenagers. Avoid drinking coffee with too much sugar to prevent rapid weight gain. Choose clear coffee origins, reputable coffee brands, and quality assurance to retain beneficial nutrients for the body.

Healthy habits:

To reduce the negative effects of coffee and maintain healthy growth, it is recommended to adopt healthy habits every day, such as:

  • Following a balanced and nutritious diet
  • Regular exercise to promote bone and joint health
  • Getting enough sleep by going to bed early and sleeping for 8-10 hours a day
  • Drinking enough water daily
  • Getting sufficient exposure to sunlight for 10-15 minutes a day before 9 AM or after 3 PM to supplement vitamin D. Vitamin D helps with calcium absorption, promoting healthy and well-developed bones.

Some other health benefits of coffee

There are several health benefits associated with coffee consumption. Firstly, the antioxidants found in coffee can help reduce inflammation, which lowers the risk of developing type 2 diabetes. However, for those already suffering from the disease, it is recommended to avoid coffee as it can increase blood sugar levels.

Secondly, drinking coffee in moderate amounts can protect the brain, as evidenced by a 2012 study in the Journal of Alzheimer’s. This is because caffeine improves brain activity, memory, and reduces the risk of developing Parkinson’s disease in older adults.

Thirdly, regular coffee consumption can improve heart health, lowering the risk of heart disease and stroke by 15%. Those with blood pressure issues should limit their caffeine intake to better control blood pressure.

Fourthly, coffee can increase energy levels by blocking receptors of the neurotransmitter adenosine, resulting in increased levels of other neurotransmitters such as dopamine. This can help improve exercise performance.

Fifthly, drinking coffee in moderation can increase lifespan, provided it is consumed in the right amounts at the right times and combined with a healthy lifestyle.

Sixthly, coffee can support gut health and change fat storage, helping to stabilize weight. Men who drink coffee in moderation can also reduce body fat.

Lastly, it is important to note that while coffee does not directly affect height, excessive consumption can hinder growth in children and adolescents. It is recommended to choose fruit and vegetable juices to purify the body and maintain a healthy diet, exercise, and sleep routine to maximize growth potential.
