Saturated fats are found in animal products like beef, milk, and cheese. This type of fat is solid at room temperature.
Saturated fats have been studied in diets for many years, but research is still mixed on whether they are good or bad.
In this article, we'll look at what saturated fats are, how they differ from other fats, their benefits and risks, and how they affect health and weight.
What are saturated fats?
Considered fats one of the major important nutrients along with both Protein andcarbohydrates, which play a key role in many aspects of body health.
Fats are made of carbon (C), hydrogen (H), and oxygen (O) molecules, andthere are three main types:-
-
Saturated fats.
-
Unsaturated fats.
-
Trans fats.
Saturated fats are filled up with hydrogen molecules and only have single bonds between carbon atoms. This saturation keeps saturated fats solid at room temperature, like animal fats.
Unsaturated fats have at least one double bond between carbon atoms. Because of this, they tend to be liquid at room temperature, like olive oil.
Also, there are many types of saturated fats depending on how long their carbon chain is. These include short, medium, and long chain fatty acids, all of which have different effects on overall health.
Foods high in saturated fats
Saturated fats are mainly found in animal products and tropical oils, andThese foods include:-
Research on saturated fats
Saturated fats are often called bad or harmful fats. They are grouped with trans fats as main causes of serious health issues like heart disease. But this is not set in stone.
For example, health groups like the American Heart Association (AHA) have advised lowering saturated fat intake to a minimum for the last 60 years. They say to replace them with nutrient-rich foods.
However, recent studies found many contradictions in old research. Like, no clear link between heart disease and saturated fats. Actually, health problems like heart disease, obesity, and type 2 diabetes have increased in the last 40 years despite these fat intake limits.
Effects of saturated fats on health
The American Heart Association (AHA) recommends that 5-6% of calories Daily intake of saturated fats.
Many studies showed that eating saturated fats raises risk factors for heart disease, including higher LDL cholesterol (bad cholesterol). LDL carries cholesterol through the blood, and too much can form plaques in arteries. This can raise risks for many health issues, including heart diseases and artery blockages.
Also, saturated fats affect levels of apolipoprotein B (ApoB), a main part of LDL cholesterol, which is also a strong indicator for heart disease risk.
So, eating saturated fats can increase risk factors for some health conditions, and it affects both bad LDL and good HDL cholesterol levels.
High-density lipoprotein or HDL (good cholesterol) protects the heart by carrying cholesterol from blood to the liver to be removed. Low HDL levels are linked to higher risks of heart disease and cardiovascular issues.
However, studies found no significant link between saturated fats and deaths from cardiovascular diseases or other causes.
Researchers also found that eating more saturated fats is linked to a lower risk of stroke, while diets high in carbs are linked to a higher risk of death.
Are saturated fats unhealthy?
Research shows eating a lot of saturated fats might harm overall health. But it’s important to know not all saturated fats affect us the same way.
For example, a diet high in saturated fats from fast food, fried products, baked goods, sugar, and processed meats probably affects health differently than one rich in saturated fats from dairy and grass-fed meats.
Also, instead of just focusing on big macros, we should look at the whole diet and its quality, and figure out which good foods can replace saturated fats.
Cutting out saturated fats from the diet
Research supports not focusing on bad or good food, but on the overall diet instead. For example, studies have looked into potential effects of butter (saturated fats) on heart health and blood sugar and found no clear link.
Similarly, other studies looked at the possible effects of butter, coconut oil, and olive oil on healthy adults aged 50 - 75. They found major changes in LDL bad cholesterol and HDL good cholesterol levels. But the research couldn't tell if cutting saturated fat overall can improve health.
Including saturated fats in the diet
You can enjoy foods high in saturated fat as part of a healthy diet. For example, some reviews found that eating saturated fat from full-fat dairy might have a neutral or protective effect on the risk of heart disease.
On the other hand, other reviews found that consuming saturated fats from processed and fried foods raises the risk ofobesity Heart disease and other health conditions, and these saturated fats differ from those in dairy and meat products.
Also, replacing saturated fats with a high carb diet might increase risks of health problems like heart disease and type 2 diabetes.
So, it’s important to focus on a balanced diet rich in nutrients andwhole grains and unprocessed foods, and it could include some foods high in saturated fats too.
The link between saturated fats and weight
Some reviews found saturated fats are more likely to be stored as visceral fat around the belly compared to unsaturated fats. Research shows eating more unsaturated fats may help with weight loss. Other studies found more saturated fat intake ties to more visceral fat.
In the end, saturated fats have been seen as unhealthy for decades. But current research shows nutrient-rich fatty foods, including saturated fats, can be part of a healthy overall diet.
