Celebrating Spring Onions!

Although available all year-round in supermarkets, spring onions are now just about coming into season and are at their peak in taste and flavour…well they didn’t get that name for nothing!

They’re basically a normal onion picked early, before the bulb has had a chance to swell up, and they belong to the same family as garlic, leeks, shallots and chives.

Spring Onions are Good for You Because…

They contain no fat, no cholesterol, and are low in calories and salt. They’re also packed full of good stuff including vitamins A and C, iron, calcium and fibre.

Research has shown that eating onions may help to lower blood pressure and cholesterol levels, and prevent the formation of blood clots. They’re also thought to protect against cancer and heart disease.

There’s More to Them Than Crispy Duck Pancakes!

Despite being small and immature, spring onions can still pack a punch! They’re ideal for quickly injecting a burst of flavour and a dash of colour into your food.

Raw spring onions are great for adding an earthy kick to salads, sandwich fillings and salsas. The greens are also a tasty alternative to chives, and can be tossed into scrabbled eggs, cottage cheese, omelets and dips.

When cooked, they can bring a subtle hint of onion flavour into a wide range of dishes, especially stir-fries and soups. They’re also delicious partnered up with ginger in Thai, Chinese and Japanese-style meals.

Handle Your Onions With Care!

Look for a bunch that’s got bright green and perky leaves. The bulbs should be hard, crisp and unblemished. Steer clear of any specimens that are slimy, wilting or limp!

What is the difference between Clementines and Satsumas?

Citrus Celebration - The Ultimate Guilt Free Snacks with Health Benefits

For me, the deliciously tangy aroma of a Clementine or Satsuma being peeled and eaten goes hand-in-hand with the festive season. At this time of year, there are so many pleasurably calorific foods and drinks around, and these sweet fruits, which come in their own convenient and natural packaging, are one of the few Christmassy things that can be enjoyed guilt-free.

Clementines and Satsumas are in season just when we need them. They’re loaded with vitamin C, so can help prevent colds and flu at a time when our bodies have to battle hard to ward off infections. They’re also a bright and sunny addition to the fruit bowl on dull, grey winter days (and you may find a few jumbled up with nuts and chocolate coins at the bottom of your Christmas stocking…but only if you’ve been good!)

But Is There Any Difference Between Them?

Lets first talk about mandarins and tangerines. Mandarin is the collective name for all small orangey-type fruit (but not the bigger oranges). Tangerines are a variety of Mandarin, and usually have seeds in them.

Clementines and Satsumas are similar to tangerines, but are cultivated to be seedless (although you’ll occasionally find seeds in them due to uninvited bees getting in on the breeding process) and are usually sweeter.

Clementines are traditionally from North Africa, whereas Satsumas originate from Japan. It’s not easy to tell the difference between the two, although the Clementines are meant to have a slightly tighter skin.

To make things even more confusing, different countries use different terms for defining the fruit. And shops have been known to mis-label the various varieties, so you may believe you’re eating a Satsuma, when actually it’s a Clementine!

The Weighty Ones are More Juicy!

As with most fruits, choose carefully and go for the ones that look shiny and healthy, without any bruising or discoloured skin. If you can, try and feel how heavy the fruit are. If they feel light, they’re likely to be disappointingly dry and juiceless.

Crunch Your Way Through Some Apples & Pears

Summer berries and salads may no longer be in season, but that’s no reason to cut back on your 5-a-day fruit and veg portions.

British apples and pears are delicious and definitely worth hunting down at the moment. Food that has been grown locally always tastes better, and you can feel virtuous for supporting British growers and reducing your food miles! Choose organic for the best taste-bud experience.

Both apples and pears have a stronger flavour if you eat them at room temperature, although storing them in the fridge will keep them fresh for longer.

Apples and pears are both low calorie and low GI, so make good weight-loss snacks. Nutritionally, they’re much better if you eat them raw with their skins on. 

Nice Pear!

One chin-dribbling, juicy pear will provide you with zinc, vitamins C and E, some B vitamins and lots of dietary fibre.

Pears are great on their own and are also really tasty in salads. Try combining the sweetness of pears with slightly bitter salad leaves such as radicchio, rocket and watercress.

For a special treat (that'll make your diet go a bit pear-shaped!) try poaching them in red wine, or drizzling baked pears with chocolate!

An Apple a Day…

Crunchy apples are full of lots of good stuff. They’re a great source of nutrients, such as potassium, calcium, vitamin C and dietary fibre.

Apples are a great snack when eaten raw, sliced up with yogurt or grated on muesli. They can also be made into a healthy sauce when pureed and served with meats such as pork.

Of course they can always be made into yummy, diet-demolishing crumbles, pies and strudels!

Did you know...

Conference pears are named after an international pear conference, where the variety won first prize in 1885.

All Bramley apples are descended from a tree that is still growing in Southwell, Nottinghamshire.

Fats: The Good, the Bad & the Ugly…

Most people are familiar with the terms trans, saturated, polyunsaturated and monounsaturated fat. But how do they differ, and what do they do?

The first thing to understand is that fats are classified by their "saturation". This means the amount of hydrogen atoms attached to the fat molecules.

The Loveable Rogue: Saturated Fat

Saturated fats are completely "saturated". In other words, each fat molecule is completely covered in hydrogen atoms.

Saturated fats remain solid at room temperature. They’re found in meat and dairy products, cooking fats and hard margarines. They're typically to blame for the high calorific value of most cakes, biscuits, chocolates and puddings!

Unfortunately, these are also the fats that raise blood cholesterol levels, promote hardening of the arteries, and contribute to blood clots, heart attacks and strokes.

Your Oily Ally: Polyunsaturated Fat

These fats are typically liquid at room temperature and are not "saturated" with hydrogen atoms.

Polyunsaturated fat may help prevent heart disease by lowering blood cholesterol levels, and could reduce the symptoms of joint problems and certain skin diseases. They include the healthy heart and brainfood fat, omega-3, which is found in oily fish salmon, mackerel, sardines and fresh (not canned) tuna.

Your Mediterranean Mate: Monounsaturated Fat

Found in vegetable oils that remain liquid at room temperature, monounsaturated fats are also not "saturated" with hydrogen atoms.

Monounsaturated fats are found in olives, olive oil, groundnut oil, nuts, and avocados. The so-called "Mediterranean diet" is rich in monounsaturated fat. Monounsaturates, have been shown to lower blood cholesterol levels and therefore help in reducing the risk of heart disease.

The Frankenstein Fat: Trans Fat

Trans fats are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid. They're found in processed, fried (especially doughnuts) and baked goods (including partries and biscuits).

They've been popular in the past because they're cheap, easy to use and last a long time. However, recent research has shown that trans fats raise your bad (LDL) cholesterol levels, lower your good (HDL) cholesterol levels, and increase your risk of developing heart disease.

How Much is Too Much?

All fats are equally high in calories and should be eaten in moderation. A good place to start is to look at the labels on the back of foods.

  • High fat is considered anything more than 20g fat per 100g
  • Low fat is 3g fat or less per 100g.
  • High levels of saturated fat is more than 5g saturates per 100g
  • Low levels of saturated fat is 1.5g saturates or less per 100g

Don’t be Fooled by “Low-Fat” Labels

Don't always assume that 'low fat' on a label means that it's a healthy choice.

All the 'low-fat" really means is that the food is 25% lower in fat than the standard equivalent. If the food is high in fat in the first place, then the low-fat version may still be high in fat!

What’s the Point of Sports Drinks & Gels?: Part 2

Re-fueling on the Run

There’s a variety of sports drinks, gels and bars on the market to provide you with a quick carbohydrate hit whilst on the run. All are designed to boost your energy levels and prevent you from resorting to using fat as a major fuel supply during endurance events.

Research suggests that you should consume between 30-60 grams of carbohydrate per hour (depending on your size and exercise intensity) when exercising. It's worth noting that this is the maximum amount that your body can deal with, so consuming more than this will not make you run faster or further!

As it takes at least 30 minutes for the carbohydrate to be absorbed into the bloodstream, it’s important to start consuming it before you start feeling tired.

Drink & Be Merry!

Sports drinks are a great way to replenish spent energy and also re-hydrate your drained body.

Most big city marathons have drinks like Lucozade Sport at regular intervals. However many people find that they can’t tolerate the taste or suffer from stomach cramps after drinking it. It's worth experimenting on training runs first!

You can buy other brands, such as the Science in Sport PSP22, which are easier to stomach. However carrying a couple of litres of liquid around 26.2 miles can be a bit cumbersome!

Get Gelled Up!

A logistically easier option is to carry energy gels, which can be tucked into shorts, belts and pockets etc.

They are essentially concentrated drinks of about 100 calories each, and they come in range of flavours and textures.  It's important to take on some water (usually around 200ml) with the gels to help them
get absorbed into your bloodstream.

Beans, Bars & Bananas

Some people carry jelly beans, bars and bananas and munch on them whilst running. These can all be good sources of quick-release energy if you eat a little and often. They also need to be consumed with plenty of water to help them be absorbed.

What Else Should You Know?

You ideally need to strike a balance between carbohydrate availability, performance and minimizing digestive distress. Practice is the best way to do this. 10 miles into your marathon is neither the time nor the place to discover that a particular sports drink gives you diarrhea!

A word of warning, if you're training for less than an hour, you should not be using sports gels or drinks. You only need to be taking on water to avoid dehydration.

Finally, the amount of glycogen stored in your muscles before you set off will have a huge impact on your performance. To boost your glycogen levels, you should eat plenty of carbohydrates in the days before, and morning of your marathon. This will mean that you will be able to run for longer and harder before you have to rely too much on your fat stores (see Part 1) for fuel.
