    • Fat-Free Milk vs. Whole Milk Nutrition: What’s The Difference ...
      • Fat-free milk is literally fat free, containing 0% milkfat by weight. Whole milk, on the other hand, contains 3.25% milkfat by weight and is most like its original state when it comes from the cow. The calorie differences between the two are due to their differing fat content.

    Recent studies suggest that skim milk might not always be the best health-promoting choice. Though many official guidelines have long recommended avoiding whole milk, it can actually be a great addition to a nutrient-focused diet.

    Milk is one of the most naturally nutritious beverages on the planet, which explains why it’s often a staple in school lunches and a popular drink for people of all ages.

    For decades, nutrition guidelines have recommended low fat dairy products for everyone over 2 years old. However, in recent years, scientists have called this recommendation into question (1).

    This article will review how the different types of milk stack up to determine which is the best option.

    There are several types of milk available in the dairy aisle of most grocery stores, which mainly differ in their fat content.

    Whole milk is sometimes referred to as “regular milk” because the amount of fat in it has not been altered. Skim and 1% milk are produced by removing fat from whole milk.

    Fat content is measured as a percentage of the total liquid by weight. Here’s the fat content of popular milk varieties:

    •whole milk: 3.25% milk fat

    •low fat milk: 1% milk fat

    •skim: less than 0.5% milk fat

    For years, nutrition guidelines have been instructing people to avoid whole milk, mainly due to its saturated fat content.

    Mainstream nutrition recommendations advise limiting saturated fat because it can increase cholesterol levels, which is a risk factor for heart disease (11).

    Based on this information, experts made the assumption that saturated fat must increase the risk of heart disease. However, there was no experimental evidence to prove that this was true (12, 13).

    In the 1970s, public policy was adopted based on this assumed connection between saturated fat and heart disease. As a result, official guidelines instructed people to reduce their saturated fat intake (12).

    A cup (237 mL) of whole milk contains 4.5 grams of saturated fat, which is about 20% of the daily amount recommended by the 2020-2025 Dietary Guidelines for Americans. For this reason, the guidelines recommend consuming only low fat or skim milk (4, 13).

    In recent years, this recommendation has been called into question. There is emerging experimental data to indicate that eating moderate amounts of saturated fat does not directly cause heart disease (14, 15).

    While those with high cholesterol levels or heart disease may need to defer to their doctor’s recommendations and monitor their intake of saturated fat, it can still be enjoyed as part of a balanced diet for individuals without those two conditions.

    In fact, multiple studies suggest that increased saturated fat intake is not directly associated with a higher risk of heart disease, stroke, heart attack, or heart disease-related death (16, 17, 18).

    Originally, researchers believed that saturated fat increased cholesterol levels, which in turn increased the risk of heart disease. However, the relationship between saturated fat and cholesterol is much more complicated.

    For starters, although saturated fat does increase levels of LDL (bad) cholesterol, it also increases levels of HDL (good) cholesterol, which can actually help protect against heart disease (19, 20).

    Additionally, there are different types of LDL, and it’s the very small, dense particles of LDL that have the most damaging effects on the heart and arteries. Though saturated fat can increase cholesterol levels, it actually changes LDL from the small, dense particles to the large, less harmful particles (21, 22, 13).

    Furthermore, other research suggests that certain foods high in saturated fat may impact heart health differently. For example, one review showed that cheese and yogurt were actually linked to a lower risk of heart disease, while red meat and butter were tied to a higher risk (23).

    Many people avoid drinking whole milk because they assume the extra fat and calories will cause them to gain weight. However, many studies have shown that consuming high fat dairy products may actually help support weight management instead.

    According to one 2016 study of 18,438 women, increased intake of full fat dairy products was linked to a lower risk of weight gain over an 11-year period. On the other hand, there was no significant association between low fat dairy intake and weight gain (27).

    Another study from 2017 found that dairy fat intake was not linked to a higher risk of weight gain, heart disease, or type 2 diabetes (28).

    Similarly, one 2020 review of 29 studies concluded that full fat dairy consumption was not associated with weight gain or fat gain in children (29).

    The relationship between milk and weight management has been a research topic for several years, and findings have been inconsistent. However, most of these studies either include all types of dairy products or focus on low fat dairy (30, 31, 32).

    In studies that look at only high fat dairy products, like whole milk, there is a pretty consistent connection between full fat dairy and lower body weight, suggesting that whole milk can be a great addition to a well-rounded, nutrient-dense diet and may help you maintain a moderate weight.

    Studies have found that whole milk could be linked to a lower risk of several chronic conditions, including:

    •Metabolic syndrome. Multiple studies show that drinking whole milk may be associated with a lower risk of metabolic syndrome, a group of risk factors that can increase the risks of heart disease, stroke, and type 2 diabetes (33, 34, 35).

    •Type 2 diabetes. In one large study, people with the highest amount of dairy-derived fatty acids in their bloodstreams had a 44% lower rate of diabetes. However, more research is needed, as some other studies have found that full fat and nonfermented dairy products may be associated with a higher risk (36, 37, 38).

    •Infertility. Although more research is needed, some studies suggest that drinking milk may be associated with improved reproductive health and fertility in women (39).

    It’s important to note that many other factors, such as physical activity, daily diet, and personal health history all play a role in the development of chronic diseases. Therefore, drinking whole milk is one small part of a much larger equation.

    Summary

    There are some situations where skim milk may be the best choice for you.

    For example, if you’re following a very low calorie diet, choosing skim milk may be a better option as it’s lower in calories but contains about the same amount of protein per cup (237 mL) (2, 4).

    Skim milk is also considered a nutrient-dense ingredient, meaning it provides a large dose of vitamins and minerals with very few calories.

    In fact, skim milk is one of the richest food sources of calcium, providing around 325 mg per cup. This is even higher than the calcium content of whole milk, which is 306 mg per cup (2, 4).

    It can also be a great way to increase your intake of several other important vitamins and minerals, including vitamin D, phosphorus, and potassium (2).

    Summary

    One of the main reasons whole milk was called out was because of its saturated fat content, which was previously directly connected to issues like heart disease.

    However, new research questions this direct connection. While individuals who are already living with high cholesterol and heart disease should defer to their doctor’s advice and limit their intake of saturated fat, people without such conditions may be able to consume it in moderate amounts without it impacting their overall health.

  5. While milk isn’t high in fat (even whole milk is four per cent fat, putting it in the ‘medium’ category), if you have it frequently, it adds up. The good news is that it’s easy to switch to lower-fat milk.

  6. Apr 11, 2024 · While skim milk and fat-free milk are generally healthy options, some individuals may find them less satiating due to the lower fat content. Additionally, the reduced fat content in these milks may affect the absorption of fat-soluble vitamins.
