Bulletin: Tangerine a Day Keeps Obesity Away

We’ve all heard that an apple a day keeps the doctor away.

But have you ever heard that a tangerine a day keeps obesity away?

Well, a new study done at the University of Western Ontario has found just that. Scientists have discovered that a certain substance found in high concentrations in tangerines prevents obesity and offers protection against type 2 diabetes in lab mice.

It’s a substance called nobiletin.

Scientists fed one group of mice a diet something similar to that of what most of western society is used to – a diet high in fats and high in sugars. This group of mice quickly and efficiently became obese, showing signs of elevated insulin and cholesterol levels – all symptoms that boost your chances of cardiovascular disease and type 2 diabetes.

A second group of mice were on the exact same diet but with one exception – they had small doses of nobiletin added to their diet.

The result?

The second group of mice experienced NONE of the symptoms of the first group.

“The nobiletin-treated mice were basically protected from obesity,” Murray Huff, a scientist at the University of Western Ontario said.

Scientists have discovered, in the second group of mice, nobiletin prevented the buildup of fat in the liver by blocking the specific genes responsible for manufacturing fat.

Nobiletin is one of the citrus bioflavanoids. Found naturally in citrus fruits and juices, nobiletin is known for having a healthy, strengthening effect on the walls of blood vessels. It’s mostly known for its anti-inflammatory and antioxidant properties as well as its cholesterol-lowering effects.

The study, which was published in the journal Diabetes, found that the naturally occurring substance nobiletin also helped to protect against atherosclerosis – the disease responsible for majority of heart attacks and strokes.

“In longer-term studies, nobiletin also protected these animals from atherosclerosis, the buildup of plaque in arteries, which can lead to a heart attack or stroke.”

I think it’s time to jump on the tangerine bandwagon.

  1. wow. what bizarre timing… I was sitting here this morning and I flipped to this blog reading this while I was eating a tangerine.:) I think this study makes a lot of sense though and I’ve seen some other studies in the past confirming the same thing.

    1. The thing I find most interesting is that many experts tell you to stay away from fruit when trying to lose weight because fruits are packed with natural sugars. But this study shows that there are some nutrients (“substances”) in fruits that actually help with weight loss. In my opinion, if you’re already fighting obesity, try incorporating tangerines into your diet. Eliminate majority of fruits you’re eating now and eat only tangerines for 4 weeks. Don’t make any other changes, track your progress and see if tangerines make a difference. That would be a good test. (Maybe you can write me back and tell me what results you find :))

      Remember that you always have to take these kind of studies with a grain of salt. I still believe it’s important to be aware. Hope that helps!

  2. I think my mom told me something like this when I was a kid. She loves tangerines. I don’t. But sometimes the best tasting stuff is not the healthiest. Fruits and vegetables is usually a great option to consider in any diet. Time to eat me some tangerines.


    1. You’re the first person I’ve met that doesn’t like tangerines! I think more often than not the healthy stuff is not the tastiest. I’m going to try to run some sort of study to see if tangerines really do make a difference when it comes to weight loss. Any ideas? Maybe a future post ๐Ÿ™‚

  3. Just a another myth to help people give them a reason why they are over weight.
    They don’t say how much it helps to lower obesity?
    Here is my guess:
    Eat Less = 100% to lose weight,
    Tangerines = 1% at the best โ€ฆ which one to choose?
    Don’t get side tracked ‘eat less if you have a lot of weight to lose’, if you are lean and want to lose more still eat less but a few tactics like carb or calorie cycling with some cheat meals to get you there! I can guarantee that will work.

  4. Very interesting study. I agree with Raymond’s comment that overall eating less is more impactful but I never mind getting another fat burning advantage, even if it’s marginal at best. Is it just tangerines that this substance is found in or other fruits/foods as well?
