Super foods, the ultimate health foods – Tomatoes

Super foods, the ultimate health foods – Tomatoes
No video selected.

Cherry, egg, vine-ripened, ox-heart or teardrop; raw, grilled, oven-roasted or sun-dried; canned, bottled or in paste form - whichever way you eat them, tomatoes are a versatile ingredient of any healthy diet and a top super food.

Tomatoes score so high for nutrition. They:

  • Are the best source of lycopene in our diets - see below
  • Contribute vitamin C
  • Are good for fibre
  • Supply folate and other B vitamins
  • Give you lots of the mineral potassium
  • Won't make you fat - 1/2 tomato has a mere 36 kilojoules (9 calories).

Is it a veggie or a fruit?

Eaten as a vegetable, but botanically classified as a fruit, tomatoes are our second favourite vegetable after potatoes. Much of this intake is in the form of tomato products like canned whole tomatoes, tomato pasta sauces, tomato paste, juice and more recently as sun-dried. And of course there's that humble childhood icon, tomato sauce.

Lycopene

The rich red colour of tomatoes isn't merely attractive to look at. It's due to lycopene, a strong antioxidant which has been shown to reduce the risk of cancer of the prostate and possibly cancer of the colon, bladder and lungs. And it appears to protect white blood cells, your body's first line of defence against infection. Several studies found that men who have the highest intakes of lycopene from tomato-based foods had a much lower risk of prostate cancer.

Cooked tomatoes are just as healthy

Interestingly processed tomato products - spaghetti sauces, tomato sauce, tomato juices - provide the most lycopene. Cooking and processing softens the tough cell walls of the tomato and increases the availability of the lycopene.

Tomatoes and arthritis

Tomatoes are sometimes avoided by arthritis sufferers, along with other members of the nightshade family like capsicum and eggplant. Reasons given are that they are too "acid" or cause a flare-up of swollen joints or stiffness.

Tomatoes and food intolerance

Along with their flavour, tomatoes contain high levels of salicylates, amines and glutamates, three natural compounds that are often the villains in migraines, digestive upsets and other allergic-type reactions collectively called food sensitivity. As with other culprit foods, it seems if a food consistently causes problems for someone, then it's best to avoid it (and it's estimated that around 30 % of arthritis sufferers have some sort of food intolerance).

At this stage, however, there's not enough evidence to ban tomatoes for everyone with arthritis. But if they upset your joints, it's wise to limit them especially the concentrated forms of tomato such as tomato paste or pasta sauce.

Nutrition stats

Per serve:

One medium tomato (weighing 130g or 4oz) supplies: 1g protein, trace of fat, 3g sugar, no starch, 2g dietary fibre and 73 kilojoules (17 calories).

Per 100g:

1 per cent protein, trace of fat, 2 per cent sugars, no starch, 2 per cent dietary fibre and 56 kilojoules (13 calories).

Easy ways to enjoy tomatoes

  • Dice a ripe tomato, removing the seeds. Mix with crushed garlic and a little olive oil. Pile the mix onto thick toasted Turkish or ciabatta slices. Add a grind of black pepper and chopped basil leaves.
  • Oven-roast Roma tomatoes and stir though risotto with basil, mushrooms and parmesan.
  • Seed and dice tomatoes and use as the basis of a quick summer salsa over barbecued steak or grilled chicken pieces.  Add chopped fresh basil, finely-chopped purple onion or green spring onions, a squeeze of lemon juice and fresh grind or two of black pepper.
  • Snack on tiny cherry or grape tomatoes.
  • Add sliced tomato to your sandwiches or melts - it's a perfect partner to cheese or ham (add a little Dijon mustard as well).

    Product snapshot: Tomato pasta sauces

    18 September 2023 by, Catherine Saxelby

    What’s in your favourite tomato pasta sauce, and how much of it? Here are the most popular sauces reviewed for your reading pleasure.

    I’ve rated nine of the most popular tomato pasta sauces in terms of their nutrition, ingredient lists and jar size. You’ll find many of these in your local supermarket. The sauces are ranked:

    • from Italian (Italy grows the reddest full-flavoured tomatoes) to Australian
    • per 100 grams, which is equivalent to 3½ ounces (the standard for comparing food products)
    • by serving size (varies between brands but is generally 100–175 g in size)
    • by ingredient list, jar size and where made (with each product’s website as the source)

    The bottom line

    When you’re next out shopping, run your eyes down the per 100 g column and look for products containing less than 400 mg sodium AND less than 5 g fat (which equals 5% fat). Most of the brands are below these levels. I like Barilla, Sacla, Leggo’s, La Gina and Mutti – but that’s just me!

    Want something to drink before dinner? Something that’s LOWER in alcohol than wine? To match his beer? Then look no further than Bundaberg’s low-sugar alcoholic ginger beer.

    You can drink Bundaberg low-sugar ginger beer straight from the can, or pour it into a long glass over ice with a slice of lime.

    Intermittent fasting vs daily calorie restriction

    3 May 2023 by, Catherine Saxelby

    As you probably know already, intermittent fasting (IF) has gained favour as an alternative regimen to daily caloric restriction (DCR). Fasting is shown to extend the lifespan of rats, and has been associated with metabolic benefits in humans, yet the results so far have been inconsistent. So, which regimen is best for healthy weight loss?

    What sort of a diet should you follow to lose that excess weight? These days, it’s pretty confusing with high-protein Keto advocates clashing with plant-protein followers … as well as intermittent fasters, juice-only dieters, no-carb dieters and no-animal (aka plant-based) dieters. Plus all the ads for anti-hunger supplements, meal-replacement shakes and home-delivered meals, more of which somehow appear every day. So, what sort of diet should YOU follow to lose that excess?

    Protein shakes for weight loss

    9 November 2022 by, Catherine Saxelby

    These days, protein shakes aren’t bought by just body builders – they’re so popular that you can readily buy a 400 g tub at your local supermarket or service station. And with tempting claims such as ‘Facilitates muscle toning’, ‘Contains transformation-making protein’ and ‘Tastes incredible, mixes easily’, why wouldn’t you grab one? But protein shakes aren’t the magic answer to all your weight-loss woes. Let’s take a look at what you get for your money.

    How to lose weight WITHOUT going on a diet

    14 October 2020 by, Catherine Saxelby

    The word 'diet' is a turn-off for most people. It sounds hard, unpleasant and unpalatable. Losing weight doesn’t have to be hard AND it doesn’t have mean sticking to a 'diet'. You can forget Paleo, Keto, Vegan and Raw, Gluten-free and Intermittent Fasting. To lose weight, you don’t have to follow any specific diet. What you need is simple, healthy, nutritious food and a few tips and tricks.

    What IS a healthy balanced diet for weight loss?

    16 September 2020 by, Catherine Saxelby

    Healthy weight loss happens when you lose weight slowly and steadily (around 1 kg or 2 pounds weight loss a week). Your goal is to lose weight while still getting your essential nutrients but from smaller portions. You certainly don’t want to be tired with no energy! That’s why you need regular healthy meals and snacks on hand to ensure your vitamins, minerals, omega-3s and fibre needs can be easily met. There is a new range of healthy weight loss meals available and it’s one that I’d like to recommend. With these ready meals, you’ll say goodbye to meal planning, shopping, meal preparation and cooking.
