GOOD FATS vs. BAD FATS

Fats may have gained a negative reputation over the years but without them, our body would not function properly. Symptoms such as dry skin, thinning hair and brittle nails are signs of a diet deficient in natural fats. Having said this, we need to ensure we are eating the correct fats and within moderation. To get a better understanding of the ‘good fats’, we spoke with Clinical Nutritionist and Nordic Naturals Spokesperson, Warren Maginn.

 

Q. What are good fats and where can we find them?

 

A. There are 2 key types of nutritional fats: polyunsaturated fats and monounsaturated fats. Both should be incorporated into our diet, in the correct amounts and balance, for optimal health.

 

Polyunsaturated Fats

 

Polyunsaturated fats provide structure and fluidity to various organs throughout our body, including the heart and muscles, optimising their function.

 

Omega-6 fatty acids, whilst technically essential, are also pro-inflammatory and the modern diet usually contains an excessive amount (even from seemingly ‘healthy’ foods such as seeds and grains). So most of us could do with avoiding these foods and the heavily processed products stemming from them (including all refined ‘vegetable oils’ – i.e. the ‘yellow’ oils found in clear plastic bottles at the supermarket).

 

Omega-3 essential fatty acids (EFAs) are the polyunsaturated fats that we really need and these are found mostly in fatty fish such as wild-caught salmon, lake trout and sardines. These types of fish contain the omega-3 that our bodies cannot produce themselves and are, therefore, essential.

 

Some seeds such as hemp and flax do also contain some omega-3, but in a much less active form, and would need to be eaten in almost prohibitively large amounts in order to be converted into the same ‘active’ forms (eicosapentaenoic acid, or EPA, and docosahexaenoic acid, or DHA) that are found in fish.

 

Monounsaturated Fats are considered the best for our health when eaten (in healthy moderation) to replace refined carbohydrates in supporting our energy needs. Having a moderate amount of monounsaturated fats in our diet may help reduce excessive cholesterol levels in our blood and lower the risk of heart conditions[1].

 

Foods that contain high levels of monounsaturated fats include olive oil. Avocados and macadamias are also high in monounsaturated fats and can be used in everyday cooking.

 

Peanut butter is also another source of monounsaturated fats and can be used in a variety of ways, such as on sandwiches or as a dip for vegetables.

 

Q. What is the key role that essential fatty acids play in our health, and why do we need them?

 

A. Omega-3

 

Omega-3 is one of the EFAs essential to optimal health. Omega-3 can benefit various aspects of our body such as brain health, joint health, heart health, skin health, and eye health. Our bodies do not produce omega-3, so we need to ensure we are getting enough of this important type of fat.

 

Omega-3 can only be obtained through certain foods or supplements. Good sources of omega-3, as mentioned before, include cold-water fish and some seeds. Two servings of wild-caught, cold-water fatty fish per week are highly recommended. When it comes to seeds, we would have to eat copious amounts of them to obtain an optimal level of ‘active’ omega-3. High-quality, purified fish oil is therefore a very effective source of omega-3 essential fatty acids. This is why supplementation of omega-3 through fish oil is so beneficial.

 

Omega-6

 

The one ‘good’ omega-6 fat we should opt for is gamma-linolenic acid (GLA), found in the seeds of evening primrose and borage plants, and in supplements made from them. Unlike the rest of the omega-6 fatty acids, GLA has unique anti-inflammatory mechanisms involved in keeping our skin hydrated. This EFA particularly benefits the skin through supporting cell membranes. In those with atopic dermatitis, it can also help support the skin barrier function.

 

The other, less healthy types of omega-6 are typically abundant in refined vegetable oils including corn and soybean oils, processed foods, and meat and eggs from grain-fed animals. This type of omega-6 can instigate inflammation. Inflammation is the process responsible for swelling, redness, blemishes, rashes and eruptions on the skin. It is important to note that we need a balance of omega-3 to omega-6 fats in our bodies to maintain balance in our function and appearance.

 

Omega-9

 

Unlike omega-3 and omega-6, omega-9 is a class of fatty acid that our bodies can produce in small amounts. However, if we do not have an efficient level of omega-3 and omega-6, our bodies struggle to produce omega-9. This is why it is beneficial to have both omega-3 and omega-6 in balance through a healthy diet balanced in both and supported through fish oil supplementation.

 

Omega-9 is a monounsaturated fat, and can easily be found in various foods in our diet. So although important, omega-9 supplementation is not as crucial to our health as omega-3.

 

 

Q. Why should we choose fish oil supplementation over eating certain foods?

 

A. It’s not that we have to choose fish oil supplementation over eating foods that contain omega-3, but we often need to, in order to compensate for the fact that our modern Western diets generally don’t provide the minimum amounts required.  Considering that our bodies cannot produce omega-3, and we are invariably getting an over-abundance of omega-6 from our diet, it is important to incorporate sufficient omega-3 supplementation to reap the benefits of well-balanced fat nutrition.

 

Q. What should we look for in a fish oil product?

 

A. With so many different types of fish oils on the market, it is important to know what fish oil is the most beneficial to your body. It is essential to research the fish oil company before purchasing to ensure it uses sustainable practices, surpasses pharmaceutical standards, has the highest purity possible, tastes great, and is in the true triglyceride form.

 

Q. The Triglyceride Form – what makes one fish oil more effective than another?

 

A. Many concentrated fish oils on the market today are in the ‘ethyl ester’ form – a ‘new-to-nature’ fat with only a few decades in the human diet. Validating many years of data, a 2010 study confirms that concentrated fish oil in triglyceride form is up to 70% more absorbable than fish oil in ethyl ester form[2]. Few fish oils are sold in true triglyceride form due to higher production costs. The benefits of omega-3 nutrition can only be enjoyed if your body actually absorbs these essential fatty acids, regardless of the amount described on the bottle label. True triglyceride form means superior absorption, greater freshness and therefore better taste and results. You can look on the label to see if the fish oil is in the true triglyceride form.

TESTIMONIALS

Hi Jessica, I believe in synchronicity so when I was guided to you .on FB I was intrigued and inspired. I turned 46 last week and my husband bought me your book. I wanted to thank you for sharing your wisdom in such a beautifully presented way. My  copy is now filled with tabs and post it notes with actual notes throughout. I am dairy intolerant since having my gallbladder removed 15+ years ago, I don't eat meat, very minimal gluten and was told 12 months ago my gut was not digesting my food properly so I wasn't receiving sufficient nutrients and taking supplements would be a waste of time.  My weight fluctuates tending to gain rather than lose but now I believe I have a tool to help me bring my body back into balance that I need for my health and longevity of life - so again thank you. The first few steps to creating a stronger path forward for my health has found its foundation in your beautiful book, The Healthy Life.

With kindest regards Samantha

I'm writing this email because I wanted to tell you how much I love your blog and how you really helped me in my health journey. Thank you for sharing all your advices and experiences.

When I started my studies, I was drinking lots of coffee and I was eaten the wrong foods, and feel bad about it, I wasn't at my best. So I had done some research on the net but at first I didn't found advices that are for me, and then I found your blog. It was exactly what I was looking for, good advices and healthy recipes. Now I'm following your advices on rest more, and snacks between meals and prep the meals and take time for myself to reconnect with my body and let go my anxiety, etc, and I have a more balanced life and have a new relationship with food thanks to you.

I bought your book and it's honestly the best book I have ever bought. I suffer from IBS and anxiety. I have paid so much money seeing naturopaths however after reading your book and all of your tips I'm noticing so much of a difference, so simple and easy to follow. And symptoms have dramatically decreased. Also you have helped me to relax. Currently drinking the protein health smoothie! Thankyou your amazing.

Hey Jessica!
I haven’t yet brought ‘The Healthy Life’, but I do have the clean life and your slim down plan! I would like to thank you so much for the knowledge your share and the message you put across about health and wellness. I’m studying Nutritional Medicine in Melbourne and absolutely love the philosophy that you share with your JSHealth community. The work you’ve done to show people that leading a healthy lifestyle isn’t boring, tasteless, difficult or depriving is amazing and hope to share the message myself one day. You’ve inspired me to start my own blog , to share the message and have taught me so many things about my own health! You should be proud of your achievements! Thank you again

- Jacinta

I searched for help and tips through the Internet and found Jessica Sepel. This is seriously not exaggerated, but she was the reason why I have dared myself to eat again, to have snacks in between, to nourish my body. I could slowly improve my negative thoughts about my body image and my stupid anxiety of gaining weight. Besides, The Cleanest Gut was awesome too! A huge thank you! Especially from my mum. Seriously, without you I wouldn’t be where I am now!

@mariashealthytaste

Congratulations on your new book! It looks absolutely gorgeous. I’ve been following you on Instagram for a few years and you’ve inspired me to slowly but surely eat healthier without giving myself a hard time when I don’t. It made me so happy (and weirdly proud) to see the Daily Mail article on The Healthy Life. I remember trying out your recipes before you even had your eBook out! I can’t wait to get my hands on the book. Keep up the great work.

– Sophie

Cooking in this way truly brought out the foodie in me and has instilled a huge passion for health and wellness! Life throws you hard and frustrating things sometimes but I truly believe that this is where we learn more about ourselves and what our passions in life are! Thank you for inspiring me on my journey to health and wellness!

@freed_from_foodie

I am a yoga teacher in Johannesburg and am thrilled to have bought your book today. I love making healthy, nutritious food for my family, friends and fellow yogis! Thank you for this book and your inspiration (had to share a pic of my book on my recipe stand in the kitchen).

– Helene

I bought your beautiful book during the week and told my bestie to go out and buy it also! I love love love it. It is the book I would give to my younger self if I could (I am 41 years old). Everything is just so sensible and informative and is definitely a book all teenagers should have. This should be a text book for girls becoming teens. I will love going back and re-reading it many many times and can't wait to make more of the recipes. Thank you Jess - you are an incredibly inspiring woman and you should feel so proud

Michelle Curtis
