What's All The Hype About Kale?


Guest post by Northeastern graduate student Meghann Jurkowski

The mighty kale has been a hot topic on the rise. Everyone seems to be drinking green smoothies or doing juicing cleanses with kale as a main ingredient. It's also been popping up in dishes at restaurants across the country and promoted heavily in all kinds of grocery stores. October 2nd was even National Kale Day! You may be looking around and wondering to yourself, what's all the hype about kale? The truth is, this nutrient packed super leafy green is something to be raving about. There are so many different kinds of kale, so many ways to prepare and eat it, it tastes great and the nutritional benefits are outstanding!

What are the health benefits associated with kale?

Nutrient Density
Kale is extremely nutrient dense so when you eat this green you are getting more nutrient bang for your calorie buck. This means that the ratio of nutrient density to calorie intake is high. One cup of kale contains 33 calories. With these 33 calories you are taking in 9% of your daily value of calcium, 134% vitamin C, 206% vitamin A, and a whopping 684% of vitamin E. Kale is also a good source of iron, manganese, copper, phosphorus and potassium. Kale has more iron per calorie than beef does!

Antioxidants
Kale is an excellent source of antioxidants, especially from vitamins A, C and K. The antioxidants carotenoids and flavonoids have been shown to have anti-cancer health benefits while lutein and zeaxanthin have been associated with eye health.

Bone Health
Kale has more calcium per calorie than milk and is loaded with vitamin K. These nutrients support the building of bones and aid in the prevention of bone loss and osteoporosis.

Lowers Blood Cholesterol
The fiber content of kale helps in lowering blood cholesterol levels. Kale also reduces the risk of heart disease. These heart health promoting properties are at their maximum potential when kale is cooked.

Other Health Benefits
Kale contains 10% of the RDA for omega-3 fatty acids (the good fats our bodies need!) which act as an anti-inflammatory. Kale also has properties that support our bodies in its detoxification process.

How do we use kale to reap all its nutritional benefits?

Kale can be eaten raw, baked, steamed sautéed....its applications are endless!

Local Produce

Summer is the perfect time to enjoy local produce because of the sheer variety of fruits and vegetables that are available. I’ve waited all winter for ripe berries, juicy tomatoes and sweet stone fruit. We get a few months of this bounty and when the season is over, we wait patiently for summer to come again so we can enjoy our favorites. Connecting and eating with the seasons can be rewarding but also a tough challenge as many of us now rely on grocery stores to provide year-round produce. FUN FACT Did you know that the average food item has traveled 1,500 miles to get to your plate? Seeking out local food, understanding how it was grown and learning more about the people who grew it can be an empowering experience. Not everyone has the opportunity to shake hands with the person that grew their food but for those that do, it carries more weight than a certification.

Plant Forward

A New Way of Eating There’s a relatively new term buzzing around the food world that you may or may not have heard of, plant forward. What does that mean you ask? Plant forward focuses on more vegetable centric dishes with meat playing more of a supporting role. Think blended burgers, stir-fry’s or grain bowls where meat is almost like a condiment. Flavors are bold and it’s all about the dish’s deliciousness whether it happens to be vegan or vegetarian, or not. Diners aren’t interested in completely removing meat from their diets so embracing a diet that is mostly plants with some meat here and there provides a comfortable middle ground. The Challenge with Red Meat Conventional animal agriculture is resource intense and less than stellar for the environment. Ruminant animals release methane gas into the atmosphere which is about twenty five times more intense than carbon dioxide. Let’s face it, our country’s enormous appetite for beef is not so great for our health and the heal...

Focus on Whole, Minimally Processed Foods

With assistance from Northeastern graduate student Crystal (Sopher) Richardson What’s the WHOLE story on Processed Foods? Nutritionists and dietitians are often asked why processed foods are bad.  It’s not an easy question to answer.  Many refer to the fact that the “Diseases of Civilization” – heart disease, hypertension, tooth decay, diabetes and some cancers did not exist before the increased popularity of processed foods. Whole and minimally processed foods are prepared without copious amounts of added fat, salt or sugar, therefore maximizing the consumption of cancer-fighting nutrients and phytochemicals, that protect your body’s cells from damage. A 2017 study of 249 adolescents showed that the consumption of minimally processed foods was inversely associated with excess weight. 1 Another study in 2016, published by Anthony Fardet showed a link between minimally processed foods and satiety versus ultra-processed foods. 2 While most people know that eating a whole a...
