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 apple is much healthier than drinking apple juice or snacking on a fruit snack with apple juice added, can we really answer the question of why?  Processed foods are higher in sodium in most cases, leading to issues such as high blood pressure and cardiovascular disease.   However, although the science can sometimes be confusing, highly processed foods can also have other effects on the body.

What we do know is that a healthy diet concentrates on consuming more whole and minimally processed foods.  The best rule of thumb? The closer the food is to its form found in nature, the healthier it will be.  These whole foods contain less fat, oil, salt and sugar and more fiber.    When choosing foods, refer to the following tips:
  • Don’t be fooled by your taste buds.  Although some processed foods may not taste salty, the majority of American’s daily sodium intake comes from grains and meat.  Beware of commercially made baked goods and breakfast cereals.
  • Use alternative seasonings such as vinegar, lemon juice and fresh herbs.
  • Avoid processed meat products such as ground beef, deli meats and sausages – as over-consumption has been linked to colon cancer.
  • Read nutrition labels on packaged foods to compare sodium and sugar.
  • Eat more fresh fruits and vegetables.  Although canned and frozen alternatives are not bad, look for those with no added salt or sugar.
  • Limit your intake of fast food.
  • Buy your bread from a local bakery.
  • In addition to your bread choice, when selecting foods like pastas, cereals, rice, and crackers always go for the whole-grain option.
  • Fresh produce is less expensive and easier to find if you “eat seasonally”.  Visit your local farmers markets to buy your fruits and vegetables.
  • Remember, meats and dairy are processed to increase shelf life.  Find a store or vendor that offers fresh local meats and dairy.

Fish For Your Heart?

Cutting back on red meat is a common recommendation for both health and sustainability. What’s less clear is what we should replace the meat with. A recent study looked at this and the results may surprise you. If not red meat, what? Red meat appears on many lists of foods to eat less of due mostly to its saturated fat and cholesterol content, and the fact that we tend to eat too much of it. A recent study looked at what we should consider substituting for red meat when we follow the advice to cut back. Of all of the substitutions the study looked at, one stood out as the best choice – fish high in omega-3s. The fatty fish showed more benefits for heart health than poultry, unprocessed meat and even lean fish. Is fish safe to eat? Fish, especially the kind that gives us omega-3s, has long been considered a healthy choice. Warnings related to contamination by mercury and other toxins has left many people wondering if fish is safe to eat. For most people, the benefits of eating fish far ...

Superfood: Tomatoes

Fruit or vegetable? It is a fruit that works well as a vegetable! Tomatoes are considered a type of superfood because they are rich in lots of great nutrients. They contain lycopenes, which is an antioxidant that offers a protective effect in the body. Tomatoes are also a great source of vitamin A, E and C, which means tomatoes contain even more antioxidants than just lycopenes. Incorporate tomatoes and tomato products to help boost your immune system as well as promote skin and eye health!    Good News: You should eat pizza!!   Through research at the Harvard School of Public Health, it was determined that consumption of oil- and tomato-based products -- specifically tomato and pizza sauce – there was an association with cardiovascular benefits.  So, choosing 1-2 slices of pizza paired with a side salad can be a healthy meal option.

Cutting the Salt!

Salt is found in more food products than you may realize. The 2015-2020 Dietary Guidelines for Americans recommend that American's should consume fewer than 2,300 milligrams (mg) per day of salt (this is slightly less than 1 teaspoon of salt). Adults age 51 and older, African Americans of any age and people with high blood pressure, diabetes or chronic kidney disease should reduce their sodium intake to 1,500 mg a day. These new dietary guidelines emphasize the importance of making meals and snacks from scratch versus choosing processed foods too often. The most common salts available are table salt, sea salt and kosher salt with the major differences among these being taste, texture, and processing. Kosher and sea salt have a larger course grain providing more air space, which in turn provides less sodium when used in place of table salt. The chefs in our kitchen across campus use kosher salt in their recipes to provide an overall reduced amount of sodium. Using items lik...
