Thanks to all the sweet treats that go hand in hand with holiday gatherings, I have no doubt that I eat more sugar during the holidays than in the previous six months combined.
And, according to a new study by researchers from the University of Alberta, that’s a huge problem — but not just for my waistline.
So, if, like me, those holiday desserts are calling your name, here’s what you need to know about what they’re doing to your health and how to protect yourself, without giving them all up…
Just 2 days of a high-sugar diet leads to serious damage
The study, published in Scientific Reports, looked specifically at how eating a high-sugar diet for even a short amount of time can result in significant health issues — specifically, inflammatory bowel disease.
You see, the researchers already knew that many people who live with colitis report that small changes in their diet can make their symptoms flare up. But the team wanted to know just how small (and for how short a time) those changes could be to lead to damage.
And, they got their answer…
They found that after only 2 days on a high-sugar diet, mice had an increased risk of inflammatory bowel disease compared with those on a healthy, balanced diet.
Yup, all it took was two days of sugar-rich foods to change their susceptibility to the disease!
In fact, the changes caused by the high-sugar diet were so extreme and fast that even the scientists were surprised…
“We wanted to know how long it takes before a change in diet translates into an impact on health. In the case of sugar and colitis, it only took two days, which was really surprising to us. We didn’t think it would happen so quickly,” said Karen Madsen, who led the study.
The antidote to sugar damage
But what could drive such a significant change in such a short time, turning the sugar-rich holiday season into a minefield of inflammatory bowel dangers?
Well, according to the research team, it all comes down to your gut bacteria and the impact food has on them.
Madsen says that when you eat a high-quality diet, rich in fiber, it serves as fuel for the “good” bacteria in your gut, which produce short-chain fatty acids critical for an efficient immune response.
However, when you switch to a high-sugar diet and decrease your fiber intake, you instead feed the “bad” microbes in your gut, such as E. coli, which lead to inflammation and a defective immune response.
Basically, you set yourself up for health failure.
But the team found a way around the problem…
The researchers found that even when mice ate a high-sugar diet, as long as they were supplemented with the short-chain fatty acids their good bacteria would normally produce on a balanced diet, their immune response and intestinal tissue normalized.
That means instead of giving up all the desserts this holiday season to protect your intestinal health, you could instead simply eat more fiber. Just make sure you eat foods with inulin fiber, which boosts your short-chain fatty acids.
“Changing someone’s diet is one of the hardest things to do, even if you tell them that it will fix their health problems,” said Marsden. “People want to eat what they want to eat, so short-chain fatty acids could possibly be used as supplements to help protect people against the detrimental effects of sugar on inflammatory bowel disease.”
Where to find short-chain fatty acids
If you choose to go the more fiber route so that your body makes its own short-chain fatty acids, good options to include in your daily diet are these foods that provide inulin fiber:
- Garlic
- Leeks
- Asparagus
- Beans
- Legumes
- Bananas
- Apricots
- Carrots
- Oranges
- Chicory root
