Exploring Coconut Oil; Is it Truly a Healthy Choice for Cooking?

coconut oil

Coconut oil has gained significant attention both in the culinary world and health industry lately. It is often hailed as a superfood with multiple uses and numerous health benefits. However, amidst all the excitement surrounding it, there remains one question that bothers many; Is coconut oil genuinely healthy for cooking?

Should I Be Concerned About the High Saturated Fat Content of Coconut Oil?

One of the primary concerns raised against coconut oil is its saturated fat content. Approximately 87% of its fat comes from saturated fats, which makes it one of the highest sources of this type of fat.This has caused concern among health experts as consuming a lot of saturated fats may lead to increased levels of 'bad' LDL cholesterol in the bloodstream. This can potentially lead to blocked arteries and raise the risk of heart disease and stroke.

However, it's important to note that not all saturated fats are the same. Coconut oil contains primarily lauric acid, which is a medium chain fatty acid. Unlike the long chain fatty acids found in some animal based saturated fats that are harder for the body to digest and may contribute to unhealthy cholesterol levels, medium chain fatty acids are absorbed more quickly by the body and can be used by the liver for energy or ketone production. Some studies suggest that this particular type of saturated fat may not pose the same risk for heart disease. However, it's worth mentioning that there is not enough strong evidence yet to recommend a high intake of coconut oil.

In addition to its saturated fat content, virgin coconut oil (obtained from coconut meat) is also rich in antioxidants and possesses anti inflammatory and antibacterial properties. In simpler terms, it offers more than just fats. It is considered one of the best plant based sources of MCTs (medium chain triglycerides), which have been shown to provide good energy sources, enhance brain function and potentially aid weight loss.

Coconut oil is a great option for sautéing, searing and frying because it can handle high heat without smoking. It adds a distinct and delicious taste to dishes, especially those with a tropical flair like prawn and pineapple curry or Indonesian nasi goreng. In vegan baking, coconut oil works well as a substitute for butter and gives cakes, cookies and muffins a rich flavor. You can even try adding it to smoothies for a touch of tropical goodness and the energy boosting properties of MCTs.

In summary, while coconut oil has its benefits, it's important to use it in moderation. It is not inherently harmful when part of a balanced diet that includes plenty of fruits, vegetables, whole grains and lean proteins. However, keep in mind that it shouldn't replace all other fats in your diet—especially heart healthy options like olive oil, avocados or fatty fish such as salmon and mackerel.

Flaxseed oil (also known as linseed oil) is gaining attention for its impressive health benefits.

linseed oil

Derived from the edible seeds of the flax plant, this versatile oil offers numerous nutritional advantages.
However, there is ongoing debate regarding whether flaxseed oil is the best choice for cooking. Some question whether its reputation as a health hero is truly deserved. Let's explore this further.

Flaxseed oil contains a significant amount of alpha linolenic acid (ALA), which is a type of omega 3 fatty acid known for its positive impact on heart health. ALA has anti inflammatory properties that can potentially reduce the risk of heart disease and stroke by combating inflammation in the body.

Additionally, flaxseed oil is rich in lignans, which are plant compounds with antioxidant and estrogen like properties. These compounds have been associated with protecting against cancer and improving hormonal balance. It's worth noting that flaxseeds contain an impressive amount of lignans compared to other plant based foods, making flaxseed oil a valuable source of these beneficial compounds.

In addition to its potential benefits for heart health and cancer prevention, consuming flaxseed oil may also have positive effects on digestive health by reducing issues like constipation, diarrhea and inflammation in the digestive tract. It has also been linked to improvements in skin health, weight management and eye health.

However, it's important to acknowledge that more research is required to definitively confirm some of these claimed benefits.

Additionally, excessive consumption of flaxseed oil, which is rich in ALA, can disrupt the balance between omega 3 and omega 6 fats. It's important to maintain a proper balance of these fats for optimal health.

While flaxseed oil offers various health benefits, it may not be suitable for all culinary purposes. Its low smoke point of 225°F (107°C) means it's not ideal for high temperature cooking methods like frying or sautéing. Heating flaxseed oil at high temperatures not only diminishes its nutritional value but also produces harmful compounds.

The best way to use flaxseed oil is in cold applications. It works well in salad dressings and sauces or as a finishing touch drizzled over cooked foods. You can also add it to smoothies, yogurt or oatmeal to boost the nutritional content of your meal.

To summarize, while flaxseed oil has earned the reputation of being a "health hero" due to its impressive nutritional profile and potential health benefits, it may not be the top choice when it comes to cooking oils because of its low smoke point. By understanding its optimal uses and limitations, you can make the most out of this valuable health product.

1. Palm Oil; This oil is commonly found in many processed foods and contains high levels of saturated fats. Regular consumption may raise LDL (bad) cholesterol and triglyceride levels, increasing the risk of heart disease. Additionally, it is strongly associated with environmental concerns like deforestation and loss of biodiversity.

2. Shortening; A hydrogenated vegetable oil that is rich in trans fats. A type of fat that raises LDL cholesterol while lowering HDL (good) cholesterol. Thereby increasing the risk of heart disease. Shortening also has a higher ratio of omega 6 to omega 3 fatty acids, which can lead to inflammation and other health issues when consumed excessively.

3. Margarine; Similar to shortening, most margarines are made from hydrogenated or partially hydrogenated oils containing trans fats and saturated fats. Regular consumption can trigger inflammation and contribute to the development of heart disease.

4. Soybean Oil: Although soybean oil has some heart-healthy omega-3 fatty acids, it is also high in omega-6 fatty acids, which can cause an imbalance in the body leading to inflammation. Plus, many non-organic soybean oils are made from genetically modified (GM) soybeans.

5. Corn Oil: Though it’s often promoted for its high polyunsaturated fats content, corn oil is unfortunately very high in omega-6 fatty acids. With the typical Western diet already far too high in omega-6 fats (and low in omega-3's), adding corn oil into the mix can promote inflammatory conditions.

6. Cottonseed Oil: This highly processed oil is filled with pesticides unless it's organic, and it's also high in omega-6 fatty acids. Plus, cottonseed oil can be contaminated with natural toxins and possibly even residual pesticides.

How to store and maintain cooking oils 

To ensure the nutritional value and flavor of cooking oils are preserved while preventing spoilage, it is important to store them properly. Here are some recommended guidelines for storing and maintaining cooking oils; 

1. Find a cool and dark spot to store your oils, like a pantry or cupboard. It is crucial to keep your oil away from direct sunlight and heat, as they can degrade its quality and impact its nutritional benefits. Oils such as olive oil, coconut oil, flaxseed oil and walnut oil are particularly susceptible to damage from exposure to light and heat.

2. Choose containers that are dark in color, preferably made of glass, to prevent light from affecting the quality of the oil.

3. Always make sure the lids or seals are tightly closed after each use to minimize exposure to oxygen, which can cause the oil to go bad over time through oxidation.

4. If you have oils high in polyunsaturated fats like walnut, flaxseed or sesame oil, you can consider refrigerating them. They might turn cloudy and thick when cold but will return to their liquid state at room temperature.

5. It's a good idea to buy oils in smaller quantities so that you can use them up quickly. The longer an oil is stored, the higher the chances of it becoming rancid.

6. Read our blog post on if cooking oils can be reused for tips on how to prepare used oils for storage.

Now let's move on and discuss how we can identify if an oil has spoiled;

1. One clear indication is a change in appearance – if an oil becomes cloudy or murky, it may have spoiled. However, keep in mind that some oils naturally solidify in colder temperatures and this doesn't necessarily mean they're spoiled.

2. Unpleasant Odor; Normally, fresh oils have a subtle scent. However, when oil becomes rancid, the smell can become quite noticeable and may resemble crayons, old nuts or stale popcorn.

3. Changed Flavor; If the oil tastes bitter, metallic or unexpectedly sour, it is likely that it has gone bad. It's always a good idea to taste the oil before using it in your cooking.

4. Thicker Consistency: Although not always evident, rancid oils may sometimes develop a thicker, more viscous consistency.
Always remember that consuming spoiled oil can lead to numerous health issues, including indigestion and foodborne illnesses. Ensuring proper storage and paying attention to indications of spoilage can help maintain the nutritional value of your cooking oils and your overall health.
