The Best and the Worst Diets and Trends for 2020

January 5th, 2020

Every year media and news outlets put out lists of what the best and worst diets and food trends of the year will be. This year has been no different. Everyone has made their health and wellness resolutions and look to these guides for inspiration and guidance. The top three overall diet plans listed in U.S. News are the Mediterranean Diet, DASH and The Flexitarian plan. These are my favorite plans and I will discuss all three. They can actually be combined/refined to create a plan that works for you.

  • The Mediterranean Diet: A plan focused on plants, whole grains, healthy fats such as olive oil, beans, legumes and fish. Moderate amounts of chicken , low fat dairy and eggs. Limiting red meat, sweets and processed foods. Stresses the importance of daily physical activity. It even allows for some red wine. This is a manageable  program that can improve heart health, liver function and help to manage weight and increase longevity.
  • DASH: An acronym that stands for: Dietary Approaches to Stop Hypertension was promoted by the U.S. based National Heart, Lung and Blood Institute to lower blood pressure but was found to have the side benefit of aiding in weight loss. It is similar to the Mediterranean Diet in that it focuses on fruits, vegetables, whole grains, low fat dairy and lean proteins. It stresses reducing processed foods, moderate amounts of sodium and increasing potassium, magnesium, calcium and fiber.
  • Flexitarian Diet: This diet encourages a primarily plant based diet including vegetables, fruits, legumes and beans with the ability to occasionally consume animal proteins. It may seem optimal to be vegan or vegetarian, but this plan allows flexibility  which makes it easier to succeed. This plan also limits processed  foods and refined sweets.

The lowest ranking diets of 2020 were the Keto Diet and the Dukan Diet.

  • Keto Diet: A Ketogenic Diet was initially created to stabilize pediatric seizure disorders.  It is a plan in which 70-75% of your calories  come from healthy fats and limiting carbs. Although the Ketogenic Diet has shown benefit with initial weight loss and blood glucose control, there are some serious concerns. This plan has been shown to increase risk of kidney stones, osteoporosis as well as risk of gout. There is great potential for nutrient deficiencies and feelings of overall unwell health “keto flu”. 
  • Dukan Diet: This plan, started in France,  is similar to the Atkins plan, which is a high protein, fat/low carb program, however it is more restrictive. NO carbs other than small amounts of oat bran are allowed and some low carb vegetables are not allowed initially such as spinach. This plan also limits fats such as steak and eggs. Due to these restrictions, it would be difficult to meat adequate nutrient needs and is very hard to follow long term.

Discussing food trends is also very popular in the New Year. A few of the predictions for 2020 are:

  • Sweet potato: The headlines are sweet potato is the new cauliflower. Over the last year we saw every permutation of cauliflower. Made into “steaks”, riced, mashed and even made into pizza and wraps. This year companies such as Banza and Caulipower are using sweet potato in new and innovative ways as a replacement for refined carbs such as sauce for Mac and Cheese to toast slices. No matter how you find it, sweet potatoes are a great addition to your diet for added fiber, beta carotene and other beneficial nutrients. 
  • Plant based meats: Everyone from Burger King to Dunkin Donuts has already jumped on the trend of plant based meats. You can’t escape this trend, and it isn’t a great one. They may be  better for the environment, but not your body. These plant based burgers/patties are considered “ultra processed”, which is not a good thing. Loaded with fillers, coconut oil and sodium, as well as other things, I would avoid.  If you want to avoid meat, consider traditional plant based burgers from companies such as Praegers, Boca or Morningstar and don’t go for the fake meat.
  • Mocktails: People are moving away from alcohol and to non alcoholic beverages. There will be an influx of non alcoholic beverages coming our way in 2020. From non alcoholic beers to gin. They may be tasty and interesting, but keep in mind they will still have non nutritive calories that we will have to be mindful of.
  • Oat milk: The age of only almond or soy milk as alternatives to dairy is coming to an end. Pay attention the the added sugars found in oat milk-just like other plant alternatives, always buy unsweetened products and use judiciously.
  • CBD infused products: We are still learning about the benefits and potential risks associated with CBD, but that will not stop food and beverage companies from pumping out as many CBD products as they can this year. Whether in your morning beverage drink or in a snack cookie, you will be finding this ingredient. CBD is most effective suspended in a fat/oil base. Always look for full/broad spectrum products. 
  • Plant butters: As we become more aware of the dangers of saturated and trans fats, food companies are looking for better alternatives to butter and margarine.  In comes plant based butters. These products will still have saturated fats, but the total amount will be lower. Look for blends of avocado oil, safflower oil and other alternatives. 
  • Probiotic and prebiotic enhanced foods: From smoothies to granola bars, pre and probiotics will be added as consumers look for more enhancement to their foods. It is important to know that these products will still come with added sugar and potentially sodium. Always look for products with less than 5 grams of sugar.
  • Fruit based flours: We are already starting to utilize alternative flours that are nut and legume based, but this year may show and influx of fruit based flours such as apple and banana flour. These flours are gluten free and have added fiber. These flours will also have the added benefit of nutrients not found in grain or other alternative flours.

Whatever the trends of the year are, it is always important to have a healthy, balanced diet that works for your lifestyle. Talk to your doctor or RD about plans that can work for you and maybe try incorporating something new in 2020. Every day is a new day to start fresh and get healthy!
