Juicing and Smoothies- How Healthy Are They?

Smoothie vs juicing Fruit and veg is good for you. No one would argue with that.

There has been a great deal of research in recent years to support the claim that eating more fruit and veg may be able to reduce the risk of heart disease, stroke, and cancer, while also helping to manage your weight. It can be a challenge to eat five portions of fruit and veg each day, even when you like vegetables. And now a new report suggests that eating 10 portions is what we need to stay healthy for longer. Most people don’t come nearly close to having enough, and I bet you’re wondering how on earth you’re going to manage that!

You’ve probably heard about the benefits of juicing and smoothies. Both are trending right now and there’s a huge debate. But what is better for your health – and losing weight- and are there any downsides? I’m going to give you the lowdown on both so you can get the hard facts from a nutrition professional and make an informed choice.

SMOOTHIES

The Benefits of Smoothies

When you make a smoothie, the whole lot is whizzed up in a blender. The juice and the pulp go in. This means that smoothies contain fibre. Fibre is good for you for so many reasons. It’s great for the digestive tract, helping to bulk out stools which helps you ‘go’ more regularly. Fibre supports weight loss because it helps slow down the absorption of sugar into the body, meaning that fruit and sugar-rich vegetables like beetroot and carrots are less likely to give you a blood sugar spike – ­ albeit a natural one. Fibre absorbs cholesterol in your digestive tract and flushes it out of your body, which is helpful for reducing risk factors for heart disease.

Dietary fibre also activates a few hormones really helpful in weight loss (called PYY and CKK and GLP-1, since you ask). These are appetite suppressors, meaning you’ll want to naturally eat less the more veg you consume. Fibre also decreases levels of the hunger hormone ghrelin, and increases another hormone called leptin, which tells your body you’re full. So, all in all fruit and veg are the good guys.

Fibre isn’t the only good thing in a smoothie. In a 2012 study in which scientists blended and juiced grapefruit, researchers found that the blended fruit had a higher concentration of the beneficial phytochemicals than juices because that compound is primarily found in the fibrous membranes of the fruit.

Given a smoothie can be packed with fibre, it can even serve as a meal replacement if you’re smart about what you add in it- more on this next (breakfast would be the perfect example).

The Downsides to Smoothies

When you eat fruit and veg you have to chew them which helps breaks down the fibre This in turn slows down the release of the sugars, helping to prevent a blood sugar spike which can lead to fatigue, low mood, increased hunger, weight problems, sleep problems etc.

On the other hand, when you blend fruits and vegetables in a machine, although the smoothie still contains fibre, it’s been broken down (literally pulverized) super-fast during the blending process- basically, the blender is doing the work your digestive system should be doing, which takes both energy and time to digest.

Even if you’re making your smoothie at home, using only fruits and vegetables with no other added ingredients, you can drink it in just a few minutes, compared with the time it would take to eat the same fruits or vegetables whole. It’s very likely that you are also getting more calories and sugar when you drink a smoothie than when eating whole fruits or vegetables. Research shows that we don’t register liquid calories as accurately as food we’ve chewed. So, smoothies enjoy a “health halo” that can be misleading.

The Best Way to Have Smoothies

If your idea of the perfect smoothie is only fruit and some liquid … Well, that’s a sugar bomb waiting to happen and is likely to upset your blood sugar balance. Plus, if consumed too frequently, this will have you start piling on the pounds.

But, if you combine a little bit of fruit and mostly veg, with a healthy source of protein such as yoghurt, a handful of nuts and seeds, nut butter  or a protein powder that would be best. Why? Firstly, with the addition of protein you’ll have a healthy, nutritious and filling meal to take with you on-the-go. And secondly, you’ll help avoid the blood sugar spike.

Also, quantity is important. To give you an idea, according to the national Eatwell Guide, we should only be having one serving of smoothie or juice, which is 150ml. That’s the same as a “mini” can of cola and less than half the size of a standard can of soft drink. If you’re using mostly veg in your juices and smoothies, and adding protein to your smoothies then the amount can be increased.

JUICING

The Benefits of Juicing

When you juice, your juicers extract the water and nutrients from what you feed it, leaving behind the pulp. Many juicers will also have a filter attachment, so you can remove even more ‘bits’ from your juice.

Given the lack of fibre, juices provide an almost immediate energy boost. The bulk of the vitamins and minerals found within a fruit are typically in the juice rather than the fibrous pulp. And without the fibre, the nutrients are absorbed into the body more efficiently. Additionally, the digestive system doesn’t have to work hard at all to process what you’re consuming. The cherry on top is that juicing allows you to eat a far higher range of nutrients from leafy greens and vegetables you wouldn’t normally eat in such quantity or blend – like cabbage and wheatgrass! Typically, juices (rather than smoothies) are a great way to detox.

 Downsides to Juicing

When you juice, the fibre is usually removed. And without the fibre slowing digestion of the sugar in fruit, the juice drives up your blood sugar rapidly which can lead to symptoms discussed above. This can also contribute to insulin resistance, a precursor to diabetes.

If you juice mostly vegetables, you’ll get a potent dose of phytochemicals and disease-fighting compounds without all the sugar. But do it incorrectly, and you can get more sugar than a soda. Thing is, many “green juices” actually do have more sugar than a can of soda. Why? Because people don’t like bitter green juices and so most contain lots of fruit juice, carrots, and beets. A study in 2014 found that, on average, fruit juices contain 45.5 grams of fructose per litre, not far off from the average of 50 grams per litre in fizzy drinks.  If it has more than 5 grams of sugar, stay away.

Verdict

Which is better depends very much on what your health goal is. Juicing offers the possibility of getting in a greater concentration of nutrients, increasing your fruit and vegetable consumption, and possibly making it easier on your tummy if have a hard time digesting the fibre in vegetables.

On the other hand, fibre IS super important in your diet, and in juices you are missing out – plus you could also be losing other important elements like antioxidants.

For weight loss, energy, mood, PCOS, high cholesterol the added fibre is a huge bonus for balancing your blood sugar levels. Smoothies provide this. They also bring the possibility of adding other beneficial ingredients, like collagen (for arthritis suffers), protein powders, prebiotics, nuts or seeds.

Ultimately, you need to consume more fruit and veg than you are currently eating. Both smoothies and juices give you options to consider.

 HEALTHY JUICES

Green juice

2 apples

4 stalks celery

1 orange

½ lemon

5 handfuls spinach

½ thumb ginger root

Start with the spinach. A good tip is to try to roll it into a ball in your hands before feeding through the juicer. Peel the orange and lemon, then juice. Cut the apples into halves, then juice the rest.

Green goddess

3 cups spinach

6 stalks celery

2 pears

½ cup parsley

½ lemon

Start with the spinach and parsley, rolling them into a ball in your hands before feeding through the juicer. Follow with the lemon (peeled), then juice the remaining ingredients.

Liver cleanse

1 apple

1 beetroot

3 beet leaves (or a small handful of spinach)

4 carrots

1 stalk celery

½ thumb ginger root

Cut the beetroot and apples in half to juice. Add the ginger and celery. Roll the leaves into a ball (makes it easier to juice). Cut the skin from the pineapple (but leave in the core – it has extra enzymes), peel the orange and then juice.

HEALTHY SMOOTHIES

Put all the ingredients in the blender with a cup of liquid (water or almond milk, etc.) to start with and increase liquid to desired consistency.

Food to boost your mood

by London Nutritionist Sylvia Hensher

Can you alter your mood through your food?

Many people are seeking to take control of their mental health using self-help, and to find approaches to help reduce the need for, or to use alongside prescribed medication. One self-help strategy is to make changes to what we eat, and there is a growing interest in how food and nutrition can affect emotional and mental health. We don’t have the whole story yet, but there are some interesting clues. Food appears to affect our mood by bringing about chemical and physiological changes in our brain structure.

A survey in the UK (1) of 200 people found that 88% of participants reported that dietary changes improved their mental health significantly: 26% said they had seen large improvements in mood swings, 26% in panic attacks, 24% in cravings, 24% in depression, 22% in irritable/aggressive feelings, 19% in concentration/memory difficulties. People also said that cutting down on food “stressors” and increasing the amount of “supporters” they eat had a beneficial effect on their mood. Stressors highlighted included sugar (80%), caffeine (79%), alcohol (55%), chocolate (53%), wheat-containing foods (48%), additives (47%) and dairy (44%). Mood supporters included water (80%), vegetables (78%), fruit (72%), oily fish (52%), nuts and seeds (51%), ‘brown’ (wholegrain) food (50%), fibre (48%) and protein (41%).

In addition, Mind, a charity which helps people take control of their mental health, has received numerous reports of improvements in a wide range of mental health problems by people making dietary changes, including: mood swings, anxiety, panic attacks, cravings or food ‘addictions’, depression (including postnatal depression), irritable or aggressive feelings, concentration, memory difficulties, premenstrual syndrome (PMS), obsessive-compulsive feelings, eating disorders, psychotic episodes, insomnia, fatigue, behavioural and learning disorders, and seasonal affective disorder (SAD) (2).

Which foods can negatively affect mood?

The foods and drinks that most often cause problems are those containing alcohol, sugar, caffeine, chocolate, wheat (such as bread, biscuits, and cakes), dairy products (such as cheese), certain artificial additives (or E numbers) and hydrogenated fats. Other commonly eaten foods, such as yeast, corn, eggs, oranges, soya and tomatoes may also cause symptoms for some people. A qualified nutritionist can help identify suspect culprits.

How can your food boost your mood?

1. Don’t avoid carbohydrates, but choose the right ones-The connection between carbohydrates and mood is all about tryptophan, a non-essential amino acid. As more tryptophan enters the brain, more serotonin is synthesised in the brain, and mood tends to improve (3). Serotonin, known as a mood regulator, is made naturally in the brain from tryptophan with some help from B vitamins. Foods thought to increase serotonin levels in the brain include fish and vitamin D.

There’s a catch though: while tryptophan is found in almost all protein-rich foods, other amino acids are better at passing from the bloodstream into the brain. Thus, by eating more carbohydrates you can help boost your tryptophan levels; carbohydrates seem to help eliminate the competition for tryptophan, so more of it can enter the brain and help boost your mood. However, it’s important to make good carbohydrate choices like whole grains, fruits, vegetables, and legumes, which also support positive mood in other ways by helping to stabilise blood sugar levels and contributing important nutrients and fibre (4).

2. Eat More Omega-3 Fatty Acids-your brain is 60 % fat if you take out all the water. This fatty tissue needs replenishing, but you need to know which fats will nourish your brain the best. Essential fatty acids known as Omega-3 and Omega-6 are intimately involved in brain function and deficiencies or imbalances in brain fats are now known to be associated with numerous mental health problems.

In particular, researchers have noted that omega-3 polyunsaturated fatty acids (found in oily fish, flaxseed, and walnuts) may help protect against depression. This makes sense physiologically, since omega-3s appear to affect neurotransmitter pathways in the brain. Past studies have suggested there may be abnormal metabolism of omega-3 in depression, although some more recent studies have suggested this association may not be as strong as previously thought. Aim for two to three servings of fish per week, of which at least 1 should be oily (5).

Some common symptoms of omega-3 deficiency or omega-3: omega-6 imbalance include:

  • Excessive thirst
  • Chronic fatigue
  • Dry or rough skin
  • Dry hair, loss of hair or dandruff
  • Premenstrual syndrome (PMS) or breast pain
  • Eczema, asthma or joint aches
  • Dyslexia or learning difficulties
  • Hyperactivity
  • Depression or manic depression
  • Schizophrenia

The best foods to feed your brain are:

  • Omega-3: flax seeds (linseeds), hemp seeds, pumpkin seeds, walnuts, salmon, mackerel, herring, sardines, anchovies, eggs.
  • Omega-6: sunflower seeds, sesame seeds, pumpkin seeds.

3. Eat a Balanced Breakfast- eating breakfast regularly can lead to improved mood, along with better memory, more energy throughout the day, and feelings of calmness (6). It seems sensible then to reason that skipping breakfast would do the opposite, leading to irritability, anxiety and fatigue.  So what should you be eating for a good breakfast? Lots of fibre from whole grains, nuts or seeds, as well as legumes (such as baked beans), some lean protein, omega-3 and/or omega-6 fats

4. Follow a Mediterranean Diet– the Mediterranean diet is a balanced, healthy eating pattern that includes plenty of fruits, nuts, vegetables, cereals, legumes, and fish — all of which are important sources of nutrients linked to preventing depression.

In particular, the low levels of the B vitamins folate and B12 status have been found in studies of depressive patients, and an association between depression and low levels of the two vitamins is found in studies of the general population (7). These B vitamins help to control “methylation”, a chemical process which goes on throughout the brain and body and helps to turn one neurotransmitter into another.  The brain uses these neurotransmitters to communicate, sending messages from one brain cell to another. Folate is found in Mediterranean diet staples like legumes, nuts, many fruits, and particularly dark green vegetables. B-12 can be found in all lean and low-fat animal products, such as fish and low-fat dairy products.

5. Balance your blood sugar levels- The most common underlying imbalance in many types of mood disorders is fluctuating blood sugar levels. The negative effects of imbalanced blood sugar levels include irritability, poor concentration, fatigue, depression and food cravings- especially for sweet foods or stimulants such as tea, coffee and cigarettes, all of which in turn send your blood sugar levels on a roller coaster. Here are the most common symptoms of blood sugar imbalances:

  • Difficulty concentrating
  • Heart palpitations
  • Fainting, dizziness or trembling
  • Excessive sweating or night sweats
  • Excessive thirst
  • Chronic fatigue
  • Frequent mood swings
  • Forgetfulness or confusion
  • Tendency to depression
  • Anxiety and irritability
  • Feeling weak
  • Aggressive outbursts or crying spells
  • Cravings for sweets or stimulants
  • Drowsiness after meals

Antioxidants and Safe Suntanning

by London Nutritionist Sylvia Hensher

How Antioxidants and Vitamins Can Help Prevent Sunburn

The amount of antioxidants that you have in your skin plays a major role in your development of sunburn. The more antioxidants you consume, the lower your risk of sunburn. Studies on UVA and UVB sunlight have taught us that our cells essentially “shut down” when the damage caused by sunlight becomes too great. When certain kinds of skin cells (called keratinocytes) are overexposed to UVA and/or UVB sunlight, they experience one particular type of stress called oxidative stress which can overload our antioxidant levels. Damage to our DNA is also part of what happens in sunburn cell formation. Foods containing effective antioxidants to boost your “internal sunscreen” include:

  • Goji berries (not the juice)
  • Raspberries
  • Blackberries
  • Blueberries
  • Green tea
  • foods rich in the carotenoids lutein and zeaxanthin ,including dark green leafy vegetables, kale, spinach, broccoli, corn, peas, Brussels sprouts, and romaine lettuce
  • vitamin C rich foods such as bell peppers, broccoli, papaya, Brussels sprouts, and strawberries
  • selenium rich foods such as mushrooms and different types of fish, including cod, pawns, tuna, snapper, halibut, and salmon
  • vitamin E rich foods such as sunflower seeds, almonds, olives, and dark green leafy vegetables

Safe Tanning Guidelines

If your skin is unused to the sun, it is important to build up your tolerance regularly and gradually. To start with, limit your exposure to 10 minutes a day, then progressively increase your time in the sun so that you can have normal sun exposure with little risk of skin cancer.

Time of Day – Early morning is the best time to sunbathe if you have not already built up a base tan, because you’re less likely to burn in the mild morning sun than later in the day.

Regular Intervals – Regular sunbathing is extremely important; you can’t cram all of your sun exposure into a two or three week vacation period and expect to experience the benefits. Intermittent overexposure can increase the danger of skin cancer. Thus, frequent, short periods of exposure are best.

Skin Exposure– For optimal benefit, strive to have at least 40 percent of your skin uncovered.

Optimal Exposure Time – A light-skinned person fairly far from the equator (such as in the UK or the northern U.S.) needs at least three 20 minute sessions per week, in bright midday sunlight and with few clothes. Longer will be needed if sunbathing occurs at off-peak times for ultraviolet light (before 12 PM or after 3 PM) or at the beginning or end of the summer (April or September).  A dark-skinned person, of course, should be outside significantly longer.
