Popular health superfoods such as chia seeds and flaxseeds are often praised for their many benefits. From improved skin health to reduced cholesterol levels, health and fitness experts often recommend incorporating these so-called “magic foods” into your diet.

While it is certainly true that these foods contain many important vitamins and minerals, not everyone should rush to consume high quantities of these popular foods. Although foods such as chia seeds have great anti-inflammatory properties and contain a high level of beneficial antioxidants, they could cause more harm than good in certain situations. For example, people with known food sensitivity may want to avoid these superfoods. Here’s why.

What are superfoods?

The term superfood is often thrown around in the health space without a clear definition. There are no clear, defining guidelines as to what classifies a food as a superfood. However, most health experts agree that superfoods, such as cranberries or goji berries, are foods that have a number of health benefits. These “health benefits” can vary depending on the type of food.

Should everyone consume superfoods?

Although health and food products may be labeled with the term “superfood,” you’ll want to clearly read ingredient labels to discover what’s truly in a product. Superfoods can be a part of a healthy, well-rounded diet; however, those with food sensitivity should take extra caution. Recent research suggests that certain superfoods can cause a spike in IgG antibodies, which are released by the immune system. These adverse reactions could take place in people who have a food sensitivity to certain ingredients, causing uncomfortable symptoms instead of the health benefits they claim.

Every person will react differently to specific foods, which is why a food sensitivity test is a great place to start. Testing for food sensitivities will help measure a person’s individual IgG antibody response, helping to fine-tune the superfoods they can comfortably consume. According to one recent study, experts estimate that every one in ten adults is likely to have a food sensitivity response to at least one food.

What symptoms does food sensitivity cause?

The symptoms of food sensitivity to a superfood vary from person to person. However, people who are sensitive may experience uncomfortable GI symptoms such as gas, bloating, or diarrhea. In addition, other common symptoms include fatigue, brain fog, heartburn, and joint pain. People who experience these symptoms after consuming “superfoods” are best off avoiding these foods and consuming other nutritious and healthy foods that do not cause symptoms.

Most common superfood sensitivities and alternatives

According to a recent test by Yorktest, chia seeds are one of the most common superfoods that can elicit a response in those with food sensitivity. Chia seeds offer great health benefits, such as high levels of omega-3 fatty acids and healthy fiber levels. However, nearly 8.9% of people in the study reacted negatively to these tiny health food seeds. Other common superfoods that may cause food sensitivities include goji berries, green tea, cranberries, and flaxseeds.

If you’re sensitive to one or more of these superfoods, there are many great health food alternatives you can safely enjoy. For example, raspberries and strawberries can be used instead of cranberries, and pumpkin seeds can be substituted for flaxseeds. Investing in a food sensitivity test is the best way to determine which superfoods you should and shouldn’t consume.

Get the “Extraction” body before Chris Hemsworth’s threequel
Extraction Workout

Movies lied to me when I was a kid. When I joined the Army, I had dreams of being an Army Ranger. Too many movies made me think I could be a special operator and maybe even get myself a great nickname like the GI Joes. Instead, I told one of the sergeants of my aspirations, and he flat out said I wouldn’t make it. Not that I couldn’t do it, but that they wouldn’t let me. I was too big. 6’5″ and 220 pounds was going to require too many calories. You see, Arnold Schwarzenegger, Sylvester Stallone, and Dwayne Johnson made me think that the elite soldiers needed to be hulking giants. Or world-class martial artists like Bruce Lee, Chuck Norris, or Jean-Claude Van Damme. And since I couldn’t do a roundhouse, I decided to follow the more practical path of the everyman like Bruce Willis, Nic Cage, and Tom Cruise.

You see, special operators need to be agile. They need mobility. That is why Chris Hemsworth adopted a workout with that goal to prepare for his third turn as Tyler Rake in his new Netflix film, Extraction 3.

Ditching the boring golf gear: Travis Mathew and Liberty London collaborate to bring personality to the course
Chair, Furniture, Person

I remember watching golf when I was a kid; everyone, and I mean everyone, looked the same. There are rules on a golf course. A collared shirt, no denim, a very specific look is what they go for. It is tradition, and tradition is hard to argue with. Then came Tiger Woods and John Daly. Tiger found a way to make this boring tradition a uniform. You could see the red Nike polo and black pants and knew exactly who it was. Daly? Well, he went the other way and patterns became a wild calling card. Travis Mathew and Liberty London found a way to mix both of these concepts to bring a bold new look to the game of golf.

What makes this collaboration particularly exciting is seeing Liberty’s heritage designs and colour language brought into the world of golf in such a fresh way. The striking print combinations, considered handfeel, and balance of high-performance golfwear with relaxed lifestyle pieces create a collaboration that feels both unexpected and distinctly Liberty. – Pere Bruach, Design Manager at Liberty London
