We have all heard the phrase that too much of a good thing is not good. The same is true with food. A new buzzword that is becoming more common online is “superfood”. The problem with all the hype around superfoods is that you are quickly led to believe that the more you eat them, the better they will be for you. That is not always the case. Here are seven “superfoods” that if consumed excessively can be bad for your health.
1) Fatty Fish
Salmon, mackerel, and sardines are loaded with omega 3 which is great for your brain and your heart. Many people pop omega 3 supplements on a daily basis in the hope of finding their inner Einstein, or at the very least hoping to lose their car keys so often. The problem with too much omega 3 is that it can cause blood thinning in healthy people. You therefore may want to limit your fatty fish consumption to once or twice a week.
Tuna is also a fatty fish but deserves its own special mention because it contains large amounts of mercury. Mercury is a neurological toxin that can adversely affect your vision, coordination, and your hearing, and speech. Tuna that is older, and therefore larger, tend to be served as premium steaks in restaurants and high-end grocery stores. On account of their age, they have accumulated more mercury. Smaller tuna tends to find its way into the cans and therefore have lower levels of mercury. As oceans become more polluted, so too do mercury levels increase.
Cinnamon is delicious. In the cult TV show Seinfeld, Jerry says: “People love cinnamon. It should be on tables at restaurants along with salt and pepper. Anytime anyone says, ‘Oh This is so good. What's in it?’ The answer invariably comes back: cinnamon. Cinnamon. Again and again.” Cinnamon is also known to be high in antioxidants and can fight inflammation and lower blood sugar levels. The problem is that cinnamon contains a compound known as coumarin which may be harmful in large doses.
Coffee is a wonderful beverage that is loaded with antioxidants and other active compounds. It is believed to reduce the risk of liver diseases, type 2 diabetes, and neurodegenerative diseases. Consuming excess coffee, however, which would mean more than 6 cups per day, could lead to insomnia, nervousness, irritability, stomach cramps, heart palpitations, and muscle tremors.
Organs are the most nutritious part of an animal, and the liver is the most dense organ in terms of nutrients. It is packed with iron, copper, vitamin B12, and vitamin A. Too much copper is not good for your brain and can increase your risk of Alzheimer's.
6) Cruciferous Vegetables
Leafy greens like kale, spinach, arugula, and broccoli have been linked to reduced risk of heart disease and cancer. The problem is that excessive consumption of these greens can hamper your body's ability to absorb iodine, and this can lead to weight gain, dry skin, constipation, and reduced energy levels.
7) Brazil Nuts
These nuts are one of the best sources of selenium which helps to make DNA and protect against cell damage and infections. Too much selenium can lead to selenium toxicity which can result in hair loss, memory problems, and digestive issues.
The bottom line when it comes to diet is the secret is to eat in a balanced fashion. In order to improve your health, you definitely want to increase your intake of superfoods. The problem is that many people latch onto a handful of superfoods and start to consume them every day. These seven foods mentioned above need to be consumed in moderation because excessive consumption can have negative consequences.
