Does Eating Dairy Foods Increase Cholesterol? What the Research Says

Cholesterol is a type of fat. When it increases, different types of diseases occur in the body. The risk of heart attack and stroke also increases manifold. Cholesterol can not eat many things. Many people avoid milk and fatty foods when they suffer from cholesterol. But is that right? What nutritionists say.

To keep cholesterol under control, many people exclude milk and dairy products from their daily diet. But doctors say, the idea of ​​increasing cholesterol levels by eating milk or dairy products is completely wrong. Indian media News 18 said in a report that milk has no role in increasing cholesterol levels.

Cholesterol is not just fat. It is a type of lipid layer. Where both fat and protein are present. There are two types of cholesterol in our body. One is low density lipoprotein or LDL or bad cholesterol. Another is high density lipoprotein or HDL or good cholesterol. It absorbs bad cholesterol and keeps the body healthy, reduces the risk of stroke, heart disease. So it should always be kept in mind that the proper level of HDL should be maintained in the body.

When affected by cholesterol, people make many wrong decisions about food. For example, first of all, milk and dairy products and meat are excluded. Here is the big mistake. According to the report published in the research paper entitled "International Journal of Obesity", drinking milk does not increase the cholesterol level but milk reduces the level of bad cholesterol in the body. So cholesterol patients eat milk without fear.

According to the study, those who regularly consume milk have a 14 percent lower risk of heart attack. Eating milk in moderation does not increase cholesterol levels and keeps weight under control. Therefore, cholesterol patients do not need to avoid milk and any dairy products.

Many people stop eating meat and eggs in addition to milk if they are affected by cholesterol. But these foods contain many beneficial ingredients like antioxidants, calcium, protein.

According to doctors, eat everything in moderation. 4-6 eggs a week, chicken twice, a glass of milk is good for the body.

Dairy products like milk, cheese, and butter are staple foods in many diets around the world. However, one question that frequently comes up is whether consuming dairy can increase cholesterol levels and contribute to heart disease. Cholesterol is a key factor in cardiovascular health, and while some dairy foods contain saturated fats, the relationship between dairy consumption and cholesterol is more complex than it may seem.

In this article, we will explore what the research says about dairy foods and their impact on cholesterol levels and overall heart health.


What Is Cholesterol?

Before diving into the role of dairy, it's important to understand what cholesterol is. Cholesterol is a waxy, fat-like substance that is found in every cell of your body. It is essential for producing hormones, vitamin D, and substances that help you digest food. However, too much cholesterol in the bloodstream can lead to a buildup of plaque in the arteries, increasing the risk of heart disease and stroke.

Cholesterol is carried in the blood by two types of lipoproteins:

  • Low-density lipoprotein (LDL): Often referred to as "bad" cholesterol, high levels of LDL can lead to plaque buildup in your arteries.
  • High-density lipoprotein (HDL): Known as "good" cholesterol, HDL helps remove LDL from the arteries and transport it to the liver to be processed and eliminated.

How Does Dairy Affect Cholesterol Levels?

Dairy products vary widely in their fat content. Full-fat dairy products such as whole milk, butter, and certain cheeses are high in saturated fats, which have been linked to increased LDL cholesterol levels. However, not all saturated fats affect cholesterol in the same way, and recent research has shown that the relationship between dairy fats and heart health may not be as straightforward as once thought.

1. Saturated Fats in Dairy

Saturated fats in dairy have traditionally been seen as harmful to cholesterol levels. High consumption of saturated fat can raise LDL cholesterol, which may increase the risk of heart disease. For this reason, dietary guidelines in many countries recommend limiting the intake of full-fat dairy products.

However, recent studies suggest that not all saturated fats are equally harmful, and dairy fat may behave differently from other sources of saturated fat, like red meat or processed foods.

2. Full-Fat vs. Low-Fat Dairy

Some research indicates that full-fat dairy may not be as detrimental to heart health as previously thought. In fact, certain studies have shown that full-fat dairy may have a neutral or even beneficial effect on cholesterol levels and cardiovascular health. For instance, full-fat dairy products can increase HDL (good) cholesterol, which can help counterbalance the increase in LDL cholesterol.

Low-fat or fat-free dairy products, on the other hand, are recommended for those who need to manage their cholesterol levels because they contain less saturated fat.


What Does the Research Say?

1. The PURE Study (Prospective Urban Rural Epidemiology)

One of the largest studies looking at dairy consumption and heart disease risk was the PURE Study, which followed over 135,000 people across 21 countries. The study found that higher consumption of dairy products, particularly full-fat dairy, was associated with lower risks of heart disease and stroke. These findings challenge the traditional advice to avoid full-fat dairy due to its saturated fat content.

2. Meta-Analysis of Dairy and Cardiovascular Health

A 2017 meta-analysis published in the European Journal of Epidemiology reviewed 29 studies involving over 900,000 participants. The study concluded that dairy consumption, particularly fermented dairy like yogurt and cheese, was associated with a reduced risk of cardiovascular disease. Interestingly, full-fat dairy products did not increase the risk of heart disease, and some even showed potential protective effects.

3. The Role of Fermented Dairy Products

Fermented dairy products like yogurt, kefir, and certain cheeses may be especially beneficial for cholesterol management. These products contain probiotics, which have been shown to help lower LDL cholesterol and improve overall gut health. Research suggests that regular consumption of fermented dairy may reduce the risk of cardiovascular disease, despite the fat content.

4. Saturated Fat Debate

The relationship between saturated fats and heart disease has been widely debated in recent years. While some health organizations still advise limiting saturated fat intake, others argue that the type of saturated fat and its source matter more than the quantity. Dairy fats, in particular, appear to have a different effect on cholesterol than other types of saturated fat.


Factors to Consider When Eating Dairy

1. Type of Dairy Matters

Not all dairy products are created equal. For example, butter and cream are higher in saturated fat and calories compared to yogurt or milk. While occasional consumption of butter may not significantly affect cholesterol levels, overindulging in high-fat dairy could contribute to increased LDL cholesterol.

2. Portion Control

Even though full-fat dairy may not be as harmful as once thought, portion control is still important. Moderation is key when it comes to high-fat dairy products. Consuming large amounts of any saturated fat, including from dairy, could lead to weight gain, which is a risk factor for heart disease.

3. Other Lifestyle Factors

Diet is only one factor that affects cholesterol levels. Regular exercise, maintaining a healthy weight, and avoiding smoking are all essential for keeping cholesterol in check. Incorporating heart-healthy foods like fruits, vegetables, whole grains, and fish into your diet can also help balance the effects of dairy.


Conclusion: Should You Avoid Dairy for Cholesterol?

The answer to whether you should avoid dairy to manage cholesterol is not black and white. While full-fat dairy products do contain saturated fats, recent research suggests that they may not have the same harmful effects on cholesterol and heart health as previously believed. In fact, some studies indicate that full-fat dairy could have neutral or even beneficial effects on cardiovascular health.

The key is moderation and choosing the right types of dairy. Low-fat or fat-free dairy options are still a good choice for those looking to limit their saturated fat intake. Fermented dairy products like yogurt and cheese may offer additional health benefits and help improve cholesterol levels.

Ultimately, it’s important to consider your overall diet, lifestyle, and any existing health conditions when deciding how much and what types of dairy to include in your diet.
