What are the benefits of coffee with milk?

In this brief article, we will provide you with the answer to the query: “What are the benefits of coffee with milk?”. In addition, we will discuss the proper ratio between milk and coffee and why you should add milk to your coffee.

What are the benefits of coffee with milk?

While it’s true that adding milk to coffee can increase its fat content and coffe and milk have health benefits of their own,  the combination of milk proteins and coffee antioxidants actually amplifies the anti-inflammatory properties within immune cells. 

These health benefits primarily stem from the activity of coffee polyphenols. Polyphenols, however, are prone to oxidation and decomposition during the process of digestion. 

Furthermore, their bioaccessibility is often reported to be low, which limits their physiological effects. As a result, researchers are currently exploring the potential of macromolecular components as encapsulation carriers to safeguard polyphenols from degradation during digestion.

Proteins, polysaccharides, and lipids found in milk can influence the presence of polyphenols and significantly affect the release and absorption of these compounds during digestion. (1)

What is the nutritional value of coffee with milk?

The nutritional value of coffee, considering the example of 1 cup of espresso coffee with approximately 100 g, is:

  • Between 0 to 2 kcal
  • 0.2g of fat
  • 0.1g of protein
  • 97.8g of water
  • 40mg of caffeine

Bearing in mind that 1 cup of regular coffee has a capacity of about 2 grams of coffee, we can say that its composition is well balanced.(2)

Adding whole milk to coffee increases its nutritional composition by 40 calories, and each teaspoon of sugar adds an extra 25 calories. Opting for skimmed milk reduces the calorie content from 40 to 21 calories.(3, 4)

What bioactive substances are present in coffee?

Coffee is a beverage that contains a diverse combination of compounds, with caffeine being the most well-known. However, coffee is also abundant in other bioactive substances that have a broad range of physiological effects. 

In fact, there are approximately 1000 phytochemicals that have been identified in coffee. 

These include phenols such as chlorogenic and caffeic acid, lactones, diterpenes like cafestol and kahweol, niacin, and trigonelline, which is a precursor to vitamin B3. Additionally, coffee is a good source of vitamin B3, as well as magnesium and potassium. (2)

What bioactive substances are present in milk?

Milk has several elements that are good for health, it is a high-protein, calcium-rich beverage. It is also an important source of: Riboflavin, phosphorus, vitamins A and B12, potassium, magnesium, and zinc.

Whole milk includes the vitamins A, E, K, and D found in milk fat. Skim milk, on the other hand, loses essential nutrients since it has no fat.(4, 5)

What are the health benefits of coffee?

Research has demonstrated that coffee can play a preventive role in degenerative disorders due to its neurostimulating, antioxidant, and anti-inflammatory effects. 

The consumption of coffee has been associated with a significant reduction in the risk of mortality related to heart disease, respiratory disease, stroke, injuries, accidents, diabetes, and infections.

While scientific studies can establish connections between specific compounds and their mechanisms of action, it is highly probable that the overall risk reduction for certain diseases is a result of synergistic or additive effects among the various compounds present in coffee. (6)

What are the health benefits of milk?

Whole cow’s milk, or milk with its original fat, provides the following health advantages when consumed on a regular basis:

It provides calcium, phosphorus, magnesium and proteins essential for bone formation and repair, it can help prevent osteoporosis since it is high in calcium and includes vitamin D.

Because it is high in protein, it aids in muscular building, it includes oligosaccharides, which are nutrients consumed by the good bacteria present in the colon, hence it helps to improve the intestinal microbiota.

Because it is high in vitamin B complex, it helps the neurological system work better. Because it is heavy in amino acids with anti-hypertensive characteristics, it can help regulate high blood pressure. (4, 5)

Does coffee consumption have any adverse effects?

It’s important to note that coffee does have some modest cardiovascular effects, such as tachycardia (increased heart rate), high blood pressure, and occasional arrhythmia. 

These acute effects on the cardiovascular system can occur shortly after consuming coffee, especially in individuals who are more susceptible to such reactions.

While any contribution of coffee consumption to the development of hypertension is likely to be small, it may still be significant for individuals who consume coffee infrequently. 

It’s worth considering that caffeine can slightly reduce the efficiency of calcium absorption in the gastrointestinal tract. (7)

What elements in milk are possibly not good for your health?

Potential health concerns arise from the fact that milk is not easily digested and absorbed by everyone, especially individuals with metabolic diseases and allergies. 

In cases such as lactose intolerance and cow’s milk protein allergy, the primary treatment involves excluding milk from the diet. Lactose intolerance, affecting approximately 75% of the world’s population, can occur in people of all ages due to a deficiency of the lactase enzyme. 

This deficiency hinders the proper digestion of lactose, leading to symptoms like flatulence, abdominal pain, and diarrhea after consuming milk and dairy products. In contrast, cow’s milk protein allergy primarily occurs during the first three years of life. 

This allergy is a result of the body’s immune reaction against the protein components of milk, triggering the release of antibodies, histamines, and other defensive agents. (5)
