[]A whole food diet prioritizes minimally processed or unprocessed foods that are close to their natural states. Eating whole foods may help improve overall health and could reduce the risk of developing certain conditions.
[]Whole food plant diets are rich in fiber and phytonutrients, which are plant-based chemicals with various health benefits.
[]This article looks at what whole foods are, their benefits, and how to eat more of them.
[]Whole foods are minimally processed, close to their natural state, and do not contain additives such as added sugars or flavor enhancers.
[]Whole foods are high in fiber, vitamins, and minerals and have many health benefits. They are also free from ingredients like trans fats and added sugars that may contribute to certain health problems, such as high blood pressure, heart disease, and diabetes.
[]Whole food diets are not specific diet plans. Rather, they prioritize eating certain foods, such as fruits, vegetables, grains, and legumes, and minimize processed foods that contain additives, chemical preservatives, and artificial ingredients.
[]A whole food diet may include minimally processed animal products such as meat and poultry but generally prioritize plant foods.
[]Following a whole food diet may improve a person’s overall health, and affect weight and chronic disease management.
[]
Effect on weight management
[]Whole food diets do not typically aim to restrict calories or control portion sizes but can still result in weight loss.
[]Research suggests that eating whole plant foods while limiting calorie-dense foods high in added sugars and fats may be an effective way to reduce and manage weight.
[]A small 2021 study highlighted the effect of an 8-week plant-based program on health. The participants, including vegetarians and nonvegetarians, lost weight and improved their blood pressure and cholesterol levels. Those with a higher body mass index (BMI) lost the most weight, averaging 5.5 kilograms (kg).
[]
Effect on chronic diseases
- Heart disease: About 18.2 million adults have coronary artery disease.
- High blood pressure: Around 45% of adults have high blood pressure or hypertension.
- Obesity: Around 74% of adults have obesity.
- Diabetes: About 11% of Americans have diabetes.
[]A 2021 study found that following a whole food diet reduced the risk factors of many chronic diseases, including:
[]These improvements could reduce the risks of chronic diseases, such as heart disease, heart failure, and stroke.
[]A whole food diet emphasizes minimally processed plant foods and may also include minimally processed animal products. These include:
- Fruits and vegetables: Whole fruits and vegetables, such as apples, berries, citrus fruits, grapes, dark leafy greens, peppers, cucumbers, and carrots.
- Whole grains: These include brown rice, quinoa, barley, and buckwheat.
- Lean proteins (including plant-based options): Plant proteins include beans, nuts, and tofu. Animal proteins include meats, seafood, and poultry.
- Nuts and seeds: These include peanuts and tree nuts, and sesame, sunflower, flax, and pumpkin seeds.
- Healthy fats: These include avocados, nuts, olives, and olive oil.
[]Transitioning to a whole food diet involves learning to identify and avoid highly processed foods and replacing them with whole foods.
[]Processed foods, such as refined sugars, dairy products, refined vegetable oils, alcohol, and cereals, account for 72.1% of people’s total calorie intake in the United States.
[]A person can learn to identify heavily processed products, such as fruit-flavored drinks and ready-made jarred sauces, and replace them with whole food alternatives, such as whole fruits and homemade vegetable sauces.
[]These tips can help people stick with a whole food diet:
[]
Plan ahead
[]Creating shopping lists and meal plans focused on whole foods can help a person manage their diet, reduce decision making before meal times, and ensure meals are varied and interesting.
[]
Prepare ahead
[]Setting aside time to prepare snacks and meals in advance helps people avoid turning to processed convenience foods when hungry. Having healthy snacks on hand and knowing what the next meal will be can help people stay on track.
[]
Try different foods
[]There is a huge variety of whole foods and recipes to choose from. People can search online or ask friends and family for tried-and-tested recipe ideas. Setting a challenge of trying one new food or recipe each week can help keep meals interesting and maintain motivation.
[]
Replace foods gradually
[]Gradually swapping out processed foods for whole alternatives may help a person adjust to a whole food diet over time. Adding one whole food at a time can help maintain changes in the long term.
[]Expecting to transition from a highly processed diet to a whole food diet in one go can make people feel restricted and lead to feelings of failure if they deviate from their whole food diet. Uncomfortable emotions like this may lead to eating more unhealthy foods.
[]
Keep a food diary
[]Some people find it helpful to record the foods they eat and how those foods make them feel. Tracking positive health changes, such as a reduction in bloating or indigestion, could help motivate a person to maintain their whole food diet.
[]
Consider supplements
[]If a person chooses to follow a whole food vegetarian or vegan diet, they may require dietary supplements to compensate for the lack of animal-derived nutrients. These supplements include:
[]Learning to read food labels to identify and avoid processed ingredients can help people transition to whole foods.
[]It may be helpful to look for foods with short ingredient lists containing simple, recognizable whole food components. A helpful rule is to exclude foods with ingredients that are uncommon in a home kitchen.
[]Whole foods generally do not contain chemical coloring additives or flavor enhancers.
[]A person can also read nutrition facts labels on food packaging, which include information on added sugars, saturated and trans fats, and nutrients. Highly processed foods often contain added sugars and high amounts of unhealthy fats.
[]A whole food diet prioritizes eating minimally processed foods close to their natural states. Some people include minimally processed animal products in their diet, while others focus on plant foods only.
[]Focusing on a whole food diet could help improve a person’s overall health, prevent certain chronic diseases, and help with weight management. However, if a person follows a whole plant food diet only, they may need to take supplements to replace key nutrients that people typically get from animal products.
