Eat More Healthy Fats

healthy fatsHere are some interesting benefits we see from including fat in our diet:
– Fat is an energy source
– Fat can keep you fuller for longer
– Fat is a key player in managing inflammation
– Fat can improve your hormonal profile
– Fat is high in certain vitamins and minerals

When looking at the metabolic processes and their ability to supply energy, it is very clear that fat is an essential component to anyone’s diet.

Fats as well as proteins have taken a lot of negative press over the years.

…As a result the popularity of ‘low fat, high carb’ came around and this is still present today.

The truth is, many people are still scared of fats, yet the research shows that adding fats to some of our meals will help with fat loss and also improve health.

The drive to demonise fats started in the 1980s, when Government guidelines and media messages told us that foods containing fat make us overweight and increase risk of cardiovascular diseases.

This was wrong!

What wasn’t made clear was that food choices and overall intake was the key factor.

To understanding fat, we need to know about the ‘right’ kinds of fat, and how much to eat. Get this right, and you’ll discover the incredible benefits that healthy fats have to offer, including better energy, increased nutrients, improved fat loss and enhanced flavour to your meals. But before you go off and start smothering all your meals with extra cheese and a side of peanut butter, let me give you a word of warning. With fats, moderation is key, as a little goes a long way.

Fat is the most concentrated source of energy, and 1 gram of fat provides around 9 calories (compared to 4 calories per gram for protein and carbohydrates). That’s why understanding portion size is so important, as calories from fats (even “healthy fats”) can quickly add up!

There are three major types of fat: saturated, monounsaturated and polyunsaturated.

The difference lies in the structure of the fatty acids they are made of. Examples of foods containing a high proportion of saturated fat include animal fat products such as cream, cheese, butter, ghee, and fatty meats. Certain vegetable products have high saturated fat content, such as coconut oil, palm oil and even cocoa. Many prepared foods are high in saturated fat content, such as pizza, processed dairy, bacon and sausages. Yep – most of the tasty stuff!

Poor old saturated fat has been at the forefront of the attack on fat

….with the World Health Organization and National Health Service all advising that we avoid this type of fat. However, if we actually look at recent research, we’ll find nothing to support fears that saturated fat contributes to cardiovascular diseases or increased obesity risk. It appears it’s not so bad after all.

Next, we have the family of unsaturated fats (polyunsaturated and monounsaturated)

…. typically known as ‘less stable’ than saturated fats, due to their chemical structure. That doesn’t mean they are more likely to harm you, but it does mean they shouldn’t be used for cooking at high temperatures.

Always use saturated fats for cooking.

There are two types of polyunsaturated fatty acids, linolenic acid (omega 3 fatty acid) and linoleic acid (omega 6 fatty acid) in foods. We call these the essential fatty acids, because they must be obtained from our diets. There’s also a lot of research to support the health benefits of a balanced omega 3 to 6 fat ratio, and you’ll often see people use omega supplements. Omega fatty acids are rich in foods such as walnuts, sunflower seeds, sesame seeds and natural oils like flaxseed and linseed.

Last but by no means least is monounsaturated fat. This has a higher melting point than polyunsaturated fat and a lower melting point than saturated fat. It is liquid at room temperature and semi solid or solid when cold. Monounsaturated fats are found in natural foods such as red meat, whole milk products, nuts and high fat fruits such as olives and avocados.

Olive oil is about 75% monounsaturated fat.

It’s also important to mention that fat products should come from high quality sources. Ideally, buy meats classified as ‘organic/grass-fed/wild’, and oils labelled ‘extra virgin’.

Potentially harmful toxins can be stored in the bodyfat of animals fed a poor diet or kept in less than ideal environments

For a healthy individual seeking a balanced diet, 30% of daily caloric requirements should come from healthy fat. This can be broken down into the three different types:

  • 10% should be consumed from monounsaturated fat
  • 10% should come from polyunsaturated fat (omega 3  and 6)
  • 10% should be from saturated fat
  • Hydrogenated fat should be avoided

Hydrogenated Fats (Trans Fats)

So far I’ve been raving about the benefits of healthy fats. What I haven’t spoke about is the fat that you should avoid; hydrogenated fats.

Hydrogenated fats are chemically classified as unsaturated fats, yet behave more like saturated fats in the body.

The term ‘hydrogenated’ means manufacturers are blasting the chemical structure of the fat, making the fat solid at room temperature, and creating a man-made saturated fat.

Here’s the bad news: hydrogenated fats are poisonous to our bodies. When we eat them, they replace normal saturated fat in our cells, and sometimes the essential fatty acids as well.

Hydrogenated fats have been linked to heart disease, diabetes, certain cancers and obesity. By limiting the amount of heavily processed foods in your diet, you’ll be avoiding these nasty fats.
