Three Reasons You Shouldn’t Worry About Antioxidants

You would have to be living under a dietary rock to not have heard of antioxidants – a kind of supernutrient extolled for their miraculous, age-defying, disease-thwarting properties. Accordingly, antioxidants are now used in marketing campaigns of everything from coffee to aloe vera skin cream.

But what is an “antioxidant” anyway? And do they actually do anything?

Simply put, antioxidants are thought to fight something called “free radicals”. Free radicals are reactive molecules that float around the body wreaking havoc. Antioxidants are molecules that neutralise free radicals, and your body produces them naturally or consumes them in ordinary food.

One thing is for sure: free radicals are bad. They have been linked to all sorts of health problems and diseases, including ADHD, cancer and Alzheimer’s disease.

So if free radicals make you unhealthy, and antioxidants fight them, consuming more antioxidants will make you more healthy, right?

That’s the prevailing wisdom behind the antioxidant craze, anyway. Unfortunately, things are a bit more complicated…

1. There isn’t only one kind of “antioxidant” or “free radical”

These terms aren’t names of specific chemicals so much as broad categories. There are loads of different antioxidants and different free radicals, and only specific antioxidants metabolised in specific ways can be of any use to the body.

So just because a food technically contains “antioxidants” doesn’t necessarily mean those antioxidants can be of any use to the body at all. It’s like saying: spice makes food taste better, therefore you should put nutmeg in your eggs Benedict.

2. Antioxidants are in ordinary food, too

Here are some foods known to contain antioxidants:

  • Coffee
  • Dark chocolate
  • Green tea
  • Acai berries
  • Kale

And here are some foods that also contain antioxidants:

  • Carrots
  • Spinach
  • Broccoli
  • Oranges
  • Apples

Simple ol’ vitamin C – yep, the same stuff that’s found in oranges and carrots – is one of the most common types of antioxidant. Also on the antioxidant list: vitamin A, vitamin E, manganese and even capsaicin, the oil that makes a chilli pepper spicy.

In fact, almost all foods contain antioxidants in some form. And even if one food contains “more” antioxidants than another, those particular antioxidants might not be beneficial to the body at all.

3. There is basically no evidence that consuming more antioxidants is healthy

It isn’t that the antioxidant craze is totally off base – adding more antioxidants to your system to fight free radicals has a certain logic to it. But there is basically no evidence that consuming more antioxidants than usual has any benefit at all. It’s kind of like taking vitamin pills: good in theory, mostly useless in practice.

As a meta-analysis by the Harvard School of Public Health put it: “The studies so far are inconclusive, but generally don’t provide strong evidence that antioxidant supplements have a substantial impact on disease.”

Of course, this doesn’t necessarily mean that there are no benefits to eating more antioxidants, only that we haven’t found any yet.

So relax, follow regular, old fashioned dietary science, and eat lots and lots of acai berries – not because they’re a superfood, but because they’re delicious!

Food Forest Farm: Permaculture in Commercial Farming

For Khoo Peng Keat, the name “Food Forest Farm” is a reminder that the farm should function like a forest. It also reflects Khoo and Food Forest Farm co-founder Billie Tan’s backgrounds in permaculture and interest in sustainable living. Permaculture is when “every little thing, every plant works together and is productive,” says Khoo. The combination of two words, “permanent” and “agriculture”, the practice was sought as a solution to the unsustainability of conventional annual agriculture. A design based on …

Brown Rice and Quinoa Loaf Bread (Vegan and Celiac Friendly)

Making this bread had been a mission more complicated than we would have anticipated. Because we were trying to create a version of gluten free bread that was free of eggs but would rise normally and retained its softness and moistness inside. After several attempts, we had successfully achieved a recipe that could pass on as loaf bread itself, with the additions of quinoa and brown-rice of course.
