Once upon a time three meals a day was considered the foundation stone of healthy eating and snacking in between was strictly forbidden if you were watching your weight. But the very latest research tells us a very different story and snacking in between meals isn’t condemned anymore; in fact it’s highly recommended. Obviously snacking on a whole bar of chocolate and a family pack of crisps when you feel that mid afternoon slump isn’t going to do you any good at all but a few strategically timed, balanced snacks can help you get more nutrients, stop food cravings, increase your energy and even keep wrinkles away.

As far as weight loss is concerned the nutritional tide is really turning in favour of snacking between meals. This is because we now know that hanging on until lunch or supper puts your body into starvation mode. Your metabolism slows right down and encourages your body to hold onto fat stores and hinders attempts at weight loss. If, however, you make sure you eat every two or three hours your body doesn’t feel under threat from starvation and doesn’t cling to fat in the same way.

It’s not just your waistline that benefits from regular snacking, however, your brain does too. This is because your brain relies on a steady supply of energy in the form of glucose from the food you eat. If you skip meals or go for long periods as you would with a three meal a day diet plan your blood sugar levels start to fluctuate so your brain doesn’t get that steady supply. The result: you feel tired, forgetful and grumpy.

In addition, studies also show that fluctuating blood sugars can encourage the release of the stress hormones – adrenaline and cortisol – which can not only contribute to the likelihood of weight gain, particularly around the middle, but can also aggravate the symptoms of the menopause, such as hot flushes, mood swings, insomnia and memory loss and increase pre-menstrual symptoms.

Finally, skipping meals or not eating often enough can make you deficient in nutrients that affect how you age. This is because snacks are a convenient and quick way to add more nutrients into your diet. For example, a handful of nuts and seeds, something you may be unlikely to add to a main meal, is bursting with skin friendly antioxidant vitamin E and essential fatty acids. Snacking also allows you to increase your intake of unprocessed, raw foods like fresh fruit and vegetables, which often shed nutrients during the cooking process, especially the antioxidant, anti-ageing vitamin C.

How, what and when?

To reap all the benefits of snacking you need to make sure you eat something small, like an oatcake or some nuts and seeds, every three or so hours. For example, after breakfast you should aim for a mid morning snack at around 11 am and then after lunch you should aim for a mid afternoon snack at around 4 pm and then after supper you could also have a very light snack just before bedtime, if you wake up in the middle of the night, so that everything adds up to three meals a day with two to three snacks in between.

This regular intake of calories and nutrients beats hunger pangs and mood swings because your blood sugar levels stay even and this sends a message to your brain that your body is not under stress and that it can keep revving your metabolism up and use your old fat stores for energy instead of clinging onto it.

Do make sure you pay attention to portion sizes though. Snacking is great for weight loss but not if you end up eating more than you normally do. If you add in snacks you do need to adjust your meal size accordingly. To do this, eat the amount of food you usually do, but spread it over five to six smaller meals and snacks instead.

Your snacks could be something like a handful of nuts and raisins, a small piece of fruit like a banana or an apple, or an oat cake spread with hummous. Remember, your meals should fit on a regular sized dinner plate and should not be piled high and your snacks should fit easily into the palm of your hand.

Your snack prescription:

The snack suggestions below can help if you want to:

• Fight Fatigue: One of the most common symptoms of blood sugar imbalance is fatigue. Eating little and often will help keep your blood sugar and your energy levels steady. Don’t forget to add some protein to your snacks though as protein slows down the rate at which your stomach empties and helps keep your blood sugar levels on an even keel. Try an organic natural yogurt with a palmful of berries and a table spoon of mixed nuts and seeds; a boiled egg with a slice of wholemeal bread or hummous with crudités.
• Lower high cholesterol: A study in the Journal of the American Heart Association found that eating a few ounces of oats a day could lower cholesterol by 16 per cent in three months so snack on a couple of oat cakes or a small bowl of porridge made from organic soya or rice milk.
• Beat Insomnia: Low blood sugar could be one of the reasons why you find it hard to get to sleep or wake up regularly in the night so try to have a snack at least 40 minutes before you go to bed. Aim for foods high in tryptophan, an amino acid that encourages sleep. Good sources are oats, peanuts and sunflower seeds so try a small bowl of oat porridge, a slice of wholemeal toast with peanut butter or a handful of sunflower seeds with a cup of camomile tea.
• Beat Memory loss/poor concentration: Study after study has confirmed the beneficial effect of omega 3 rich oily fish, like tuna, mackerel or salmon and nuts and seeds on brain function. To stay alert for longer aim for a few pieces of oily fish or a selection of sunflower, sesame or linseeds for your mid morning or mid afternoon snack when your concentration is most likely to be at its lowest ebb.
• Beat Mood swings: Snacking on low GI complex carbo-hydrates that release a steady supply of glucose to your brain is a great way to keep your blood sugar levels and your mood stable so try some mixed bean salad or a delicious bowl of comforting oat porridge with a spoon of honey or maple syrup for sweetness.
• Protect yourself against osteoporosis: To keep your bones healthy you need a steady supply of calcium, antioxidants and vitamins; so try a handful of raspberries, blueberries or strawberries and top them with a few tablespoons of organic natural yogurt and a teaspoon of ground linseeds (flaxseeds) to give your bones and joints a boost.
• Lose weight: One of the best ways to shift weight is to boost your nutrient intake so your food is digested more efficiently and to keep your blood sugar levels stable because weight gain is often a symptom of blood sugar imbalances. Snacking is the perfect way to achieve both these objectives, especially if you snack on negative calorie foods like broccoli, carrots, courgettes and celery. These foods are negative calorie foods because they use up more calories in digestion than they provide. To make them more interesting dip them into hummous or guacamole.
• Fight wrinkles: The secret of healthy skin is essential fat which keeps it hydrated and keeps wrinkles and dry skin at bay. To keep your skin glowing, try snacking on four or five olives or whole almonds (both rich in essential fats) with a piece of fruit.
• Beat symptoms of menopause: Foods rich in calming phytoestrogens will help balance your hormones and by so doing ease menopause related symptoms such as hot flushes, poor concentration and bloating. You could snack on a tablespoon of flaxseeds (linseeds) a day with some anti-ageing berries. Remember you don’t always have to eat soya; other legumes, such as chickpeas and lentils, are good sources of phytoestrogens too.

Girls who take magnesium supplements as adolescents may be giving themselves stronger bones for the future.

Researchers at the Yale University School of Medicine took a selection of girls aged 8 to 14 and gave them either a daily 300 mg supplement of magnesium – taken in two doses – or a placebo. The year-long test was double-blind. Researchers found the girls who were given the magnesium had significant increases in body mineral content, meaning stronger bones.

The U.S. Department of Agriculture says the daily recommended intake of magnesium is 240 mg for boys and girls aged 9 to 13, and 360 mg for girls aged 14 to 18, levelling off at 300 mg as adults. Boys between the ages of 14 and 18 should take in 410 mg and keep it up as an adult.

Magnesium is found in plenty of foods, but it is found in the largest quantities in nuts (especially almonds and cashews), halibut and porridge. Good amounts of magnesium can also be found in yogurt and beans. Approximately 50 percent of the magnesium found in the average human is found in our bones, according to the web site of the National Institutes of Health.

The Yale research was reportedly the first of its kind involving children and it is published in the February, 2007, Journal of Clinical Endocrinology & Metabolism.

The benefits of apple cider vinegar have been touted by the ancient Egyptians and claims of its benefits go back to Hippocrates. It has traditionally been used to treat many ailments including cancer, joint pains, arthritis, high cholesterol, osteoporosis, high blood pressure and many more.

Cider vinegar is made by the fermentation of apples and it is this fermented fruit acid which contains a host of beneficial vitamins and minerals including potassium, magnesium, calcium, iron and other trace minerals, as well as pectin. It is thought that pectin, which is a fibre, can attach itself to cholesterol globules and remove excess from the body. It is also thought to help with the thinning and circulation of blood and in reducing high blood pressure.

Cider vinegar is known traditionally as a powerful detoxifying food as it breaks down mucus and phlegm in the body. It has also been used as a remedy for arthritis as it is supposed to be able to break down the acid crystals which can harden in the joints causing pain.

Research has shown that when vinegar is added to food, calcium absorption from that food is increased, so good for your bone health and prevention of osteoporosis.

Cider vinegar is also helpful in controlling negative bacteria. Adding a few drops of tea tree essential oil to your bath, together with 3 cups of pure apple cider vinegar, can be very helpful when you have a vaginal infection.
