Food as Medicine

It can be very tempting to follow the latest headlines claiming that certain foods will prevent disease, make you live longer or get you to your perfect pants size. Unfortunately the science of nutrition just doesn’t work that way. This October as pink pops up everywhere and talk focuses on prevention, treatment and finding a cure for breast cancer, what do we actually know about food and cancer?

Antioxidants: Fruits, vegetables and whole grains are credited with many health benefits, including the possibility of reducing cancer risk. One possible reason is the presence of antioxidants such as beta-carotene, lycopene, and vitamins A, C, and E. Antioxidants have the ability to protect us from damage by free-radicals that could lead to cancer. Our bodies don’t produce enough antioxidants on their own, so we need to get them from food. The results around antioxidant supplements, however, are not so good. In some cases, risk of cancer actually increased with supplements. Eating more whole plant foods is a relatively safe and delicious approach that may help to reduce cancer risk.

Tea: Tea is one of the most popular drinks around the world, and also one of the most studied. Tea contains catechins, a type of polyphenols, which are thought to be responsible for tea’s health benefits. Catechins, like the nutrients found in fruits and vegetables, have antioxidant activity. The evidence for tea’s role in cancer prevention isn’t strong enough to put it in the category of an official recommendation. The risks of drinking tea, especially green tea with its high catechin and low caffeine levels, however, are low. To keep the risks even lower, choose green or white teas more often and drink them between, instead of with, meals.

Garlic: Garlic belongs to the Allium family of plants, which also includes onions, chives, leeks, and scallions. Garlic contains a variety of bioactive compounds which may be beneficial to health. Like other foods, the evidence for garlic’s benefits in fighting cancer are inconclusive, but shows some potential. Eating garlic, as opposed to taking a supplement, has few risks beyond the telltale garlic breath.

While we may be able to improve our overall health and possibly help to reduce our risk of cancer with what we eat, it is important to remember that getting regular medical care with appropriate screening tests is still key.

4 Tips To Avoid Stress Eating During Finals

It's the week of finals and suddenly there's so much to do and not enough time to do it. With projects, papers, studying, all-nighters, and early wake-ups, indulging in your favorite (and maybe not so good for you) foods seems like the perfect way to relieve some of that finals stress. When we turn to food to relive stress, it tends to be food that comforts us and makes us feel good, which a lot of times is a carton of ice cream, a slice of pizza, or your favorite piece (or bag) of candy. The truth is, finals may not only be a stressful time of the semester but a time where weight gain occurs in stressed out students. The combination of a large amount of sedentary time studying and test taking, little to no exercise, and stressful or late-night eating is a recipe for weight gain. Another truth is that we may not even recognize that we are in fact stress eating due to being completely preoccupied. So how do we avoid this stress eating before it takes place? Here are four tips to...

To Juice or Not To Juice?

Depending on who you talk to, juice is either part of the latest health trend or on the list of things to avoid. Understanding what juice does and doesn’t offer can help you decide if it is right for you. The Up Side: Fruits and vegetables offer a variety of health-promoting nutrients, many of which are still available in the juice squeezed from them. Juices can be a convenient and tasty way to get those nutrients. Juices also offer a way to get fruits and vegetables that you may not usually eat in the whole form. For example, cranberry juice is a popular alternative to whole cranberries and a great way to get some important antioxidants. People who don’t normally eat spinach may find that when juiced with other vegetables and fruit, they enjoy it. The Down Side: With about 50-115 calories per cup, fruit and vegetable juices are not low calorie drinks. For that reason, drinking a lot of juice could potentially make weight management more difficult. Research suggests that people who dri...

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...
