When you achieve healthy eating it can have a big influence on the following factors:
Nutrient Supply: A balanced diet provides your body with all the essential nutrients it needs to function correctly. This includes macronutrients like protein, carbohydrates, and fats, and micronutrients such as vitamins and minerals.
Weight Control: Eating balanced meals helps control weight by ensuring you consume enough nutrients without consuming too many calories. Overconsumption of calories leads to weight gain and associated health issues such as obesity, diabetes, and heart disease.
Heart Health: A diet low in saturated and trans fats, cholesterol, and sodium can lower your risk of heart disease. Foods rich in fibre and omega-3 fatty acids are beneficial for heart health.
Bone Health: Foods rich in calcium and vitamin D, such as dairy products, are necessary for bone health. They help in maintaining bone density and prevent osteoporosis.
Digestive Health: A diet high in fibre aids in proper digestion and can prevent digestive issues such as constipation and diverticular disease.
Prevent Diseases: A healthy diet can help prevent a range of chronic diseases, including diabetes, heart disease, stroke, some cancers, and osteoporosis. Nutrient-dense foods boost your immune system, helping protect you from illness.
Brain Health: Certain nutrients, like omega-3 fatty acids and antioxidants, are crucial for brain health. They can improve memory and concentration and may reduce the risk of neurodegenerative diseases like Alzheimer's.
Mental Health: Recent research has found links between diet and mental health. Nutrient-rich diets can help reduce the symptoms of depression, anxiety, and other mental health disorders.
Energy Levels: Eating a balanced mix of nutrients ensures you get sustained energy throughout the day. This can improve your productivity, physical performance, and overall well-being.
Longevity: Healthy eating, along with other lifestyle factors such as physical activity and not smoking, has been associated with a longer lifespan.
Healthy eating in detail
Eat plenty of fruits and vegetables
The U.S. Department of Agriculture (USDA) recommends that adults eat at least 1½ to 2 cups of fruit and 2 to 3 cups of vegetables per day. This can be a challenge, but it is important to try to get as many fruits and vegetables into your diet as possible.
The exact amount of fruits and vegetables you should eat can vary based on factors such as age, sex, and level of physical activity. However, a general guideline promoted in most European countries is to aim for at least 5 portions of a variety of fruit and vegetables each day. This recommendation is widely accepted and often referred to as the "5-A-Day" rule.
A portion is generally defined as:
- 1 medium-sized piece of fruit (like an apple or banana)
- 1/2 cup of chopped, cooked, or canned fruit or vegetables
- 1 cup of raw leafy vegetables (like spinach or lettuce)
- 1/4 cup of dried fruit
- 3/4 cup (6 ounces) of 100% fruit or vegetable juice (but limit juice intake as it can be high in sugar)
So for example, you might have a banana and a cup of strawberries at breakfast, a large salad (2 cups of mixed lettuce and vegetables) at lunch, an apple in the afternoon, and a half cup of cooked vegetables at dinner. That would be five servings for the day.
It's also good to aim for a variety of colours among your fruits and vegetables, as different colours often represent different types of nutrients. For instance, orange and red fruits and vegetables are often high in vitamin A, while green vegetables are high in vitamins K and C.
Remember, fresh, frozen, canned, and dried fruits and vegetables all count towards your daily intake. There are also many frozen and canned fruits and vegetables that are just as nutritious as fresh fruits and vegetables. Just be cautious about added sugars in canned and dried fruits, and sodium in canned vegetables.
There are many ways to incorporate fruits and vegetables into your diet. You can eat them as snacks, add them to meals, or drink them in juice or smoothies.
If you are not used to eating a lot of fruits and vegetables, start by adding one or two servings per day. Gradually increase the amount of fruits and vegetables you eat until you reach the recommended amount.
Choose whole grains over refined grains
Whole grains are a good source of fibre, vitamins, minerals, and antioxidants. They are also a good source of complex carbohydrates, which provide the body with sustained energy.
Refined grains, on the other hand, have had their bran and germ removed. This process removes many of the nutrients and fibre that are found in whole grains. Refined grains are also higher in calories and carbohydrates than whole grains.
Eating whole grains instead of refined grains can help you maintain a healthy weight, reduce your risk of chronic diseases, and improve your overall health and well-being.
Choosing whole grains over refined grains is a healthier choice for several reasons:
Nutrient Content: Whole grains are packed with nutrients including fibre, vitamins (like B vitamins and vitamin E), minerals (like iron, zinc, and magnesium), and various beneficial plant compounds. On the other hand, the refining process strips grains of the bran and germ, removing much of the fibre and many other key nutrients. While some refined grains are enriched, meaning certain vitamins and minerals are added back in, they still usually have less fibre and fewer nutrients than whole grains.
Dietary Fiber: Whole grains are a great source of dietary fibre. Fibre is important for digestive health as it adds bulk to your diet and helps prevent constipation. It can also help you feel full, which can help control your weight. Furthermore, dietary fibre has been linked to a lower risk of heart disease, type 2 diabetes, and certain types of cancer.
Blood Sugar Control: Whole grains have a lower glycemic index compared to refined grains, which means they are absorbed more slowly and cause a slower rise in blood sugar levels. This can help prevent spikes and crashes in blood sugar, making you feel full for longer and providing a steady source of energy. This is particularly beneficial for people with diabetes but is also beneficial for everyone else.
Heart Health: Regular consumption of whole grains has been linked to lower cholesterol and lower levels of triglycerides (a type of fat in the blood), both of which are risk factors for heart disease. The fibre in whole grains can also bind to cholesterol and help to remove it from the body.
Weight Management: Because whole grains can make you feel full with fewer calories, they can help prevent overeating and aid in weight management. Some studies have also suggested that people who eat more whole grains may have lower body weights and less belly fat.
Gut Health: The fibre in whole grains can also help promote a healthy gut microbiome, which is linked to a reduced risk of several chronic diseases.
To make sure you're buying whole grains, look for the word "whole" before the grain's name on the ingredient list (like "whole wheat" or "whole grain barley"). If it just says "wheat" or "barley," it's likely refined.
Here are some examples of whole grains:
- Whole wheat
- Brown rice
- Wild rice
Here are some examples of refined grains:
- White bread
- White rice
- White pasta
- White crackers
- White bagels
- White flour
Choose lean protein sources such as fish, chicken, and beans
Choosing lean protein sources such as fish, chicken, and beans is an important part of a healthy diet for several reasons:
Low in Saturated Fat: Lean proteins are typically lower in saturated fat compared to fattier cuts of meat. High intake of saturated fats has been associated with increased levels of "bad" LDL cholesterol and an elevated risk of heart disease.
Essential Nutrients: Lean protein sources are packed with essential nutrients. For example, fish is high in omega-3 fatty acids, which are important for heart and brain health. Chicken is a great source of vitamins B3 and B6, while beans provide plenty of fibre, vitamins, and minerals.
Weight Management: Protein is more satiating than carbohydrates and fats, which can help control your appetite and contribute to weight management.
If you're following a vegetarian diet, there are many protein-rich foods you can include in your meals. Here are a few examples:
Legumes: Beans, lentils, and chickpeas are all excellent sources of protein and are rich in fibre and various other nutrients. They can be used in a wide variety of dishes, from salads and soups to stews and curries.
Tofu and Tempeh: These are made from soybeans, which are a complete protein, meaning they provide all the essential amino acids your body needs. Tofu and tempeh can be used in stir-fries, salads, sandwiches, and more.
Quinoa: Unlike many plant-based proteins, quinoa is a complete protein. It's also a good source of fibre and various vitamins and minerals.
Greek Yogurt: Greek yoghurt is a great source of protein. It's also high in calcium and probiotics.
Nuts and Seeds: These are not only good sources of protein but also provide heart-healthy fats and fibre. Examples include almonds, walnuts, chia seeds, and flaxseeds.
Seitan: Also known as wheat meat or wheat gluten, it's high in protein and can be used in a variety of dishes to mimic the texture of meat.
Eggs: They are a great source of high-quality protein, as well as several important nutrients like vitamins B2, B12, D, selenium, and choline.
Remember, it's important to eat a variety of protein sources to make sure you're getting all the essential amino acids your body needs. And as with any food, moderation is key. Too much protein can be harmful, especially for people with kidney disease or other health conditions.
Limit unhealthy fats such as saturated and trans fats
Limiting unhealthy fats like saturated and trans fats is an essential part of a balanced, healthy diet. Here's why:
Heart Health: Saturated fats and trans fats have been linked to an increased risk of heart disease. These types of fats raise your level of low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol. High levels of LDL cholesterol can lead to the buildup of plaque in your arteries, which can increase your risk of heart disease and stroke.
Weight Control: Foods that are high in these types of fats are often high in calories. Consuming too many of these high-calorie foods can lead to weight gain, which can increase your risk of a variety of health problems, including heart disease, type 2 diabetes, and certain types of cancer.
Diabetes: A diet high in trans fats can also increase your risk of developing type 2 diabetes.
While it's important to limit these types of fats, it's equally important to replace them with healthier types of fats. Monounsaturated fats (found in foods like avocados, nuts, and olive oil) and polyunsaturated fats (found in foods like fish, walnuts, and flaxseeds) can help lower your LDL cholesterol levels and increase your high-density lipoprotein (HDL) cholesterol, often referred to as "good" cholesterol.
It's also worth noting that not all saturated fats are the same. The type of saturated fat found in coconut oil, for example, might not be as harmful as the type found in animal-based foods. However, more research is needed in this area and it is still recommended to use such fats sparingly.
As with any part of a healthy diet, balance and moderation are key. You don't need to completely eliminate all unhealthy fats from your diet, but you should aim to limit your intake of these fats and replace them with healthier alternatives when you can.
Limit added sugar
Limiting added sugars is a crucial aspect of a healthy diet for several reasons:
Calories without Nutrients: Added sugars contribute calories to your diet but provide virtually no essential nutrients. Foods that are high in added sugars often displace healthier foods that offer vitamins, minerals, fibre, and other nutrients that your body needs. This is why they're often referred to as "empty calories."
Weight Gain and Obesity: Sugary foods and beverages are often high in calories and can contribute to weight gain if consumed in excess. Over time, this can lead to obesity, which increases the risk of numerous health problems, including heart disease, type 2 diabetes, and certain types of cancer.
Tooth Decay: Consuming too much sugar can lead to cavities and tooth decay. When you eat sugary foods or drink sugary drinks, the sugars interact with the bacteria in your mouth to form acids, which can damage tooth enamel.
Heart Health: High-sugar diets can lead to obesity, inflammation, high triglyceride levels, diabetes, and other risk factors linked to heart disease. Moreover, consuming too much added sugar can increase blood pressure, a major risk factor for heart disease.
Blood Sugar Levels and Diabetes: Consuming a lot of added sugar can cause blood sugar levels to spike and then crash, leading to fatigue, irritability, and cravings for more sugar. Over time, this can lead to insulin resistance and the development of type 2 diabetes.
Fatty Liver Disease: Overconsumption of added sugars, particularly fructose, can lead to an accumulation of fat in your liver, which can result in non-alcoholic fatty liver disease.
To limit added sugars in your diet, it's advisable to read food labels carefully, as sugar is often hidden in foods where you least expect it, such as bread, pasta sauces, and salad dressings. Additionally, try to limit processed foods and opt for whole foods whenever possible, as these tend to be lower in added sugar.
Drink plenty of water
Water plays a vital role in the functioning of your body, which is why it's essential to drink plenty of it. Here are several reasons why water is crucial in a healthy diet:
Hydration: Your body is about 60% water and needs to be continually hydrated throughout the day. Water aids in maintaining your body's fluid balance, which is important for digestion, absorption, circulation, creation of saliva, transportation of nutrients, and body temperature regulation.
Calorie Control: Often, people mistake thirst for hunger, leading to consuming more food than necessary. Drinking water can help manage your calorie intake because it helps you feel full without adding extra calories.
Metabolism Boost: Proper hydration helps optimize your metabolism, allowing your body to burn calories more efficiently. Even mild dehydration can slow down metabolic functions and lead to fatigue.
Digestion and Nutrient Absorption: Water helps break down food so your body can absorb nutrients. It also prevents constipation by adding bulk to stools and making them softer.
Detoxification: Water is needed for the kidneys to remove waste products and toxins from the blood. If you don't drink enough, you may be at higher risk for kidney stones and other health problems.
Physical Performance: Adequate hydration is essential for optimal physical performance. Dehydration can lead to diminished athletic performance, including reduced endurance, increased fatigue, and lower motivation.
Cognitive Function: Proper hydration is important for brain function. Even slight dehydration can impair functions like concentration, alertness, and short-term memory.
The amount of water you need can vary based on factors like your age, sex, weight, physical activity level, and overall health. A common recommendation is to drink eight 8-ounce (240 ml) glasses of water a day, which equals about 2 litres, or half a gallon. This is known as the "8x8 rule" and is easy to remember.
However, it's important to note that individual needs for hydration can greatly vary, and you might need more water if you're physically active, live in a hot climate, or are pregnant or breastfeeding. Always listen to your body's signals for thirst, and ensure you're consuming enough water throughout the day to stay properly hydrated.
Using the advice when you come to make your meals should really help you with your daily needs to eat healthily and give you the best chance in life.
