Fruit - Fact or Fictions



Fruit seems to be an all or nothing principal lately so it’s high time we cleared some myths and got down to the facts.

What foods are considered common fruits?

Acai berries, Apple, Apricots, Avocado, Banana, Blackberry, Blueberries , Cherries, Coconut, Cranberry, Cucumber, Dates, Fig, Goji berries, Grapefruit, Grapes, Kiwi, Lemon, Lime, Lychee , Mango, Melon, Nectarine, Orange, Papaya, Passion Fruit, Peach, Pear, Pineapple, Plum, Pomegranate, Prunes, Raspberries, Strawberries, Tangerine, Tomato, Watermelon.

What are the health benefits of having fruit?

Fruits are loaded with vitamins, minerals, antioxidants, water and fibre. They are naturally low in fat and in calories. Fruit can reduce of the risk of cardiovascular diseases, cancer, weight gain, bone loss, kidney disease. It can help fuel your body for exercise and to maintain a healthy weight and body shape.

What are the best fruits to have?

Each fruit has their own health benefits and a wide variety is important for optimum health. There is no one fruit that is better than another however some of the more ‘superior’ fruits because of their concentration of nutrients and antioxidants are:

·         Blueberries = antioxidants and vitamin C
·         Banana = starchy carbs and potassium
·         Grapes = resveratrol
·         Avocado = fibre, vitamin E and folate
·         Goji Berri = antioxidants and vitamin A
·         Kiwi fruit = vitamin A, E, magnesium and potassium
·         Pineapple = bromleain

When should I eat fruit?

Ideally at the beginning of the day to fuel your body and brain for the day as well as around your exercise. Fruit is fantastic source of carbohydrate for fuel for example if you are planning to go for a run in the evening ensure you have some fruit with protein at your afternoon tea.

Avoid eating fruit on its own to prevent spikes in your blood sugar levels, as well as late at night after dinner as that is when you are least active and will shortly retire to bed.  

Can you have too much fruit?
Yes. You can have too much of anything. Too much of any food whether it’s deemed ‘good’ or ‘bad’ for you can cause health concerns. For example too many carrots in your diet will cause your skin to have an orange pigment, just as too much tuna in your diet can lead to mercury poisoning and too much potato chips in your diet will increase your salt intake thus water retention, your blood pressure and puts you at greater risk for stroke and heart disease. 

Too much fruit in your diet can lead to lack of intake of other essential foods leading to displaced nutrients. What this means is you are consuming a more carbohydrate rich food which is low in essential fatty acids, heme-iron, calcium and protein. Too much carbohydrate intake and too little activity can lead to weight gain. It can also cause a disruption in your digestive system leading to an increased instance of diarrhoea, bloating, cramp and gas. It can also lead to elevated blood glucose levels and for those with insulin resistance concerns (diabetes, PCOS) can cause damage the blood vessels that supply vital organs increasing risk of heart disease, stroke, kidney disease, vision problems as well as nerve problems. 

If I am insulin resistant can I have fruit?

Absolutely. But limit yourself to about 2 pieces per day and be sure to team it with a slow release nutrient such a protein to avoid the glucose spike. An example would be a piece of fruit with some nuts and seeds

How much fruit should I have?

For the average person 2-3 pieces of fruit per day will suffice. 
·         Fruit with your morning oats and LSA
·         A piece of fruit and with some nuts as a snack
·         Some avocado in your chicken and salad for lunch

What if you don’t have fruit in your diet – are they health implications? 

Here is a list of possible health outcomes by removing fruit from your diet
·         Nutrient deficiency
·         Poor immunity
·         Poor wound healing
·         Poor eye health
·         More free radical damage (aging, cancer etc.)
·         Poor blood clotting
·         Poor digestion
·         High cholesterol
·         Fluid retention
·         Poor weight management
·         Increased risk of cardiovascular concerns
·         And so on.

Can I have fruit juice instead of the whole fruit?

Not all fruit juices are created equal.  Fresh with pulp is always best. Without the skin & pulp you are missing fibre and a lot of the vitamins. What you also need to consider is to make the 250ml glass of orange juice it takes roughly oranges. Whilst it is the nutrients of oranges it is also the sugar of 5 oranges. Try to have a mix of fruit and vegetable juice and always team it with some protein (i.e. protein powder, nuts etc.)

Egg-sposed : Myths & Facts

Are eggs good for you? Are they bad for you? How many is too much? Can I only eat egg whites?

These are things I hear on a regular basis & there is so much misinformation about eggs so I’m going to start clearing it up!

Egg stats
  • a large whole egg contains roughly 6g of protein 
  • contains choline (essential for cell membrane function, neurotransmission, prevents homosycstine build up), lutein (essential for eye & skin health) and zeaxanthin (carotenoid important for vision) 
  • contains just about every vitamin and most minerals (except vitamin C)

Myth: Eating eggs raises your cholesterol levels.
Truth Dietary cholesterol found in eggs has little to do with the amount of cholesterol in your body. Roughly ¼ of your body's blood cholesterol comes from your diet and the other ¾ of blood cholesterol is produced by your body. In fact Saturated and trans fats have much bigger effects on blood cholesterol levels. Studies show that people with high cholesterol, eating one egg a day, have shown no increase in their body’s cholesterol levels.  

Myth: Eggs are better stored on the bench top for better cooking results
Fact: Refrigerating eggs reduces the risk of salmonella & keeps them fresh

Myth: Raw eggs have more protein than cooked eggs
Fact: A large egg contains 6g of protein served raw OR cooked
Fact #2: Cooked eggs have 40% more protein than raw because Biotin (found in eggs yolks) is a b complex vitamin essential for cell growth, the metabolism of fats, and energy production. Raw eggs eliminates biotin because of avidin (found in egg whites) is a biotin binding protein when consumed in its raw form, thus cooking the egg avoids the possibility of biotin deficiency.  

Myth: Egg whites have more protein & nutrients than whole eggs
Fact: FALSE!!!! Egg whites less protein than compared with a whole egg, most of the sodium and very little of anything else. Egg yolks are one of the most nutritious foods known to man! They contain almost all vitamins & minerals our diets require (minus Vitamin C). The whole egg is ALWAYS better from a nutritional point of view, period.




Whole egg (per 100g) Egg White (per 100g)
Protein 12.4g 11.6g
Energy 583kJ 204KJ
Fat 9.5g 0g

Myth: One egg every day too much
Fact: FALSE; majority of people can’t have too many eggs. Those with significantly high cholesterol would be limited to one a day. Eggs are an amazing source of protein & nutrients that our bodies thrive on.

Great ways to have eggs:
  • boiled as a snack 
  • scrambled with smoked salmon, spinach tomato & mushrooms for breakfast 
  • frittata with vegetables & a side of salad as a quick dinner
  • omelette packed full of your favourite vegetables at any meal

Improve Your Mood With Food!

Picture Source

Here are some simple ways to improve your mood with the foods you’re eating.  Avoid refined foods & increases whole foods is a simple way to help improve your mood & here are some more examples.

Firstly about our neurotransmitters Serotonin and Dopamine. 

Serotonin is an important neurotransmitter in multiple functions including regulating sleep cycles, influencing mood, learning, pain perception and the immune system When serotonin is too high you may feel sluggish, when serotonin levels are low you will have intense food cravings particularly for carbohydrates. To increase your serotonin ingesting foods high in it’s precursor (tryptophan) is the most simple way. Foods high in tryptophan include, turkey, cream cheese, ricotta, meat , poultry, and some seeds and nuts

 Dopamine is a neurotransmitter that controls the brains pleasure centre. When dopamine is low it may enhance boredom, lack of interest and motivation, poor communication and depressive activity. When it’s too high it may cause you to be more aggressive, take more risks and have distorted perceptions of reality. It too has a precursor called tyrosine, which is also a precursor to L-dopa, dopamine, norepinephrine and epinephrine. These are responsible for alertness, increased energy with quicker, more accurate reaction times. Tyrosine is found in eggs, meats, poultry, fish, nuts, seeds, legumes grains and avocados,

Endorphins are chemicals that the body releases to cope with pain, and promote a positive state. A food substance that is closely related is phenylethylamine, which is found in chocolate! Yes that’s right chocolate. Phyenylalamine unfortunately only lasts in the body from 10-20minutes when ingested and why so many people reach for chocolate when they are stressed.

Feeling cranky? When was the last time you ate?? Regularly eating & keeping and your blood sugar levels level with good quality protein, low glycaemic index foods, plenty of fresh fruits & vegetables & essential fatty acids will improve your mood dramatically.

Feeling anxious? Omega-3 fatty acids found in salmon, tuna, mackerel, avocado, nuts and seeds have shown extensive research support for both the prevention and treatment of clinical depression, mood and anxiety disorders. They are essential for brain and nervous system function and are required for myelin synthesis.

Other nutrients suggested to improve mood are magnesium, folate and other B vitamins,.
