If you prefer a healthy lifestyle or maintain less body fat from the time and effort you devote to exercise, you must supply yourself with proper nutrition. There are some nutrition facts that almost everyone agrees on. Some people even agree that the way you eat dictates as much as 80% the way you look. Here are the 10 nutrition facts everybody agrees on.
1. Refine Carbs are Bad for Health
There are a bunch of contrasting points of view about macronutrients, such as protein, carbohydrate, and fat. Some believe fat is the source of all diseases, while others think carbs are the key performers in obesity and different chronic diseases. However, processed carbohydrates are not healthy.
What are refine carbs?
Refined carbohydrates are also known as high glycemic carbs or processed carbohydrates. There are two primary kinds of refined carbs include:
Sugars: Carbohydrates that have been processed, such as sucrose (table sugar), high fructose syrup in sweet products that contain added sugar.
Refined grains: These are grains that have been stripped off from their fiber and nutritious parts. White bread made from refined flour (white flour) is the most common source.
When high-carb foods such as cereals, grains are refined, the most nutritious parts are removed. Only some amounts of digestible carbohydrates are left behind. Those who base their diets on processed carbs may need fiber and many other healthful nutrients . As a result, they are at risk of chronic diseases, such as diabetes and heart disease .
Whole-grain cereals, beans, vegetables, and many fruits are examples of unprocessed carbohydrates. Sugar and refined flour (white bread) are examples of processed carbohydrates. Whole foods contain a variety of vitamins and antioxidants. Many that eat a lot of refined carbs may lack in fibre and other essential nutrients. It is essential to eat unprocessed whole food in order to stay healthy.
2. Vegetables Are Good For You
According to the NOURISH by WebMD, the word “vegetable” refers to the edible parts of plants, which are usually their leaves, roots, fruits, or seeds. Vegetables are a staple food all over the world and a significant component of modern agriculture. Most health experts recommend you to eat vegetables regularly because they are low in calories but rich in nutrients. A rotating diet of different vegetables is one of the best ways to get nutrients from your food.
Benefits of vegetables
Vegetables are high in important vitamins, minerals, and antioxidants, all of which offer several health benefits to your body. Carrots, for example, are known for being high in vitamin A, which is essential for eye health as you get older. According to studies , , , eating vegetables can enhance health and a lower risk of diseases. Some health benefits of vegetables include:
Improved digestive health: Vegetables are high in dietary fiber. It aids in passing of food through the digestive tract. It can also increase vitamin and mineral absorption in the body.
Lower risk of heart disease: Vegetables contain vitamin K and potassium, which can prevent calcium buildup in the arteries. This will reduce your risk of arterial damage and help avoid many potential heart health problems. In addition, vegetables can keep your blood pressure in a normal range.
Helps Control Diabetes: Vegetables are high in fibre, which is needed for proper digestion. They have a low glycemic index, so the blood sugar will not spike immediately after eating them.
Vegetables are rich in essential vitamins, minerals, and antioxidants. Eating vegetables can help you avoid chronic diseases in the long run.
3. Supplements Cannot Replace Foods
Almost anyone will agree that nutrition is nothing further than the value of their nutrients. But it’s likewise a trap that many nutrition practitioners fall into. The minerals and vitamins you absorb from an inexpensive multivitamin are just a limited part of the entire volume of nutrients in meals. Thus, supplements cannot contest with vitamins and minerals you absorb from the whole food.
Whole food vs. supplements
Whole foods have three major advantages over dietary supplements:
Greater nourishment: Whole foods are versatile, providing a complete range of micronutrients that your body needs to function properly.
Essential fiber: Whole food contains fiber and can help minimise the risk of type 2 diabetes, colorectal cancer, stroke, and heart disease.
Protective substances: Many whole foods contain protective substances such as antioxidants, which slow down the process that causes cell and tissue damage by free radical oxidation.
Some supplements, such is vitamin D, which is hard to get it from an ordinary diet, are essential to the body. For several reasons, vitamin D is essential to preserve healthy bones and teeth. People who are on a vegan diet should also take supplements.
The minerals and vitamins you absorb from an inexpensive multivitamin are just a limited part of the entire volume of nutrients in meals. Supplements cannot compete with whole nutritious foods.
4. Whole Foods Diet is Good for Health
Processed food is usually not as healthy as whole food. As the food system gets more industrialized, the health of the people gets worse day by day. During food processing, many of the useful nutrients in the food are withdrawn to extend shelf life. Not only do food manufacturers remove healthy nutrients like fiber, but they also include other harmful ingredients like added sugar and trans fats. Processed foods are filled with many artificial chemicals, some of which have a doubtful safety profile.
What you can eat?
A whole foods diet is not a set meal plan and can be viewed in a variety of ways. The aim is to eat as much whole foods as possible. For example, whole foods are actual food that are not processed. You can eat potatoes but you can’t eat potatoes chips, which are processed and packed. These processed foods contain artificial ingredients, preservatives, and additives, which are not good for your health.
They removed many of the valuable nutrients in food during processing to increase shelf life. Many artificial chemicals are present in processed foods, some of which have a questionable safety profile.
5. Sugar is Bad for Health
Excessive added sugar consumption can increase blood pressure and chronic inflammation, both of which are pathological pathways to heart disease. Excess sugar intake, especially in sugary drinks, contributes to weight gain by tricking your body into turning off its appetite-control mechanism because liquid calories are less satisfying than calories from actual foods. Drinking sugary drinks makes it easier for people to add more calories to their daily diet , , , , , .
How much sugar to eat?
It’s difficult to tell because sugar isn’t a necessary nutrient in your diet. The Institute of Medicine, which establishes recommended dietary allowances (RDAs), has not set a formal RDA for sugar.
The high sugar (fructose) content of added sugar is usually criticized. This is because the liver metabolizes sugar. Thus, everybody agrees that high intake of sugar has been associated with a non-alcoholic fatty liver condition, insulin resistance, raised triglycerides, abdominal obesity, and high levels of LDL (bad) cholesterol.
6. Omega-3 Fats Are Essential
Omega-3 fatty acids are essential for proper functioning of your body. For instance, docosahexaenoic acid (DHA), an omega-3 fatty acid, represents 10–20% of fat composition in the brain . A low intake of omega-3 is related to a lower IQ, depression, different mental diseases, heart disease, and many other serious disorders .
What type of Omega-3 is the best?
There are three primary types of omega-3 fat:
- eicosapentaenoic acid (EPA)
- docosahexaenoic acid (DHA),
- alpha-linolenic acid (ALA)
ALA comes usually from vegetable oils, while the best sources of DHA and EPA are fatty fish and fish oils. Other excellent sources of EPA and DHA are grass-fed animal meat and omega-3 enriched eggs. The plant ALA requires conversion into DHA or EPA to function in our body. This alteration process is ineffective in humans . It is best to eat fatty fish or fish oils to fulfill the need for DHA and EPA.
Omega-3 fatty acids are important for the body to function properly. Not taking enough omega-3 fatty acids is linked to physical and mental health problems.
7. No Ideal Diet for Everyone
People are all different. Complex variations in genetics, body type, physical activity, and status can involve which type of diet you should pursue. Some people do well on a moderate-carb diet, while others are on a vegetarian high-carb diet. Any diet that works for one person may not work for another person. To figure out what you should accomplish, a genetic test is important. Try a few specific things until you discover something you realize you can stick to.
Any diet that works for one person may or may not work for another. As a result, a genetic test is essential to determine what you should do.
8. Preventing Vitamin D Deficiency is Important
Vitamin D is an essential vitamin that serves as a hormone in our body. The skin produces vitamin D when it is in contact with direct sunlight. This is how humans got most of their daily needs from the sunlight. A dominant part of the world population is deficient in this essential nutrient today. In many places, the sunlight isn’t available throughout most of the season. Even where there is a sun, many individuals live inside and apply sunscreen when they come out.
Danger of vitamin D deficiency
If you’re deficient in vitamin D, thus you’re losing a significant hormone in the body. VD deficiency can cause many severe conditions, including diabetes, cancer, osteoporosis and so on , , . If you think you are deficit in vitamin D, visit your doctor and have a blood test. Unfortunately, it is tough to get sufficient vitamin D from an ordinary diet. If getting more sunlight is not a choice, consuming a vitamin D supplement or a tablespoon of cod liver oil every day is the best way to avoid deficiency.
Vitamin D is a necessary vitamin that acts as a hormone inside the body. The deficiency can lead to a variety of serious conditions, including diabetes, cancer, and osteoporosis.
9. Artificial Trans Fat is Bad for Health
Trans fats are vegetable oils that are hydrogenated. Food industries use these oils in food products. The intake of trans fats may cause different chronic diseases, such as abdominal obesity, inflammation, and cardiovascular disease , , . Trans fat is widely regarded as the worst type of fat to consume.
Trans fat is the worst type of fat. A diet rich in trans fat raises the risk of heart disease. Heart disease is the leading cause of death in adults.
10. Lifestyle Change is Important
Weight-loss diets are for a short period. They may serve short-term results, but as quickly as the diet ends and you eat junk meals repeatedly, you will gain those weights back. Many people who lose a lot of weight on a diet finish up gaining it back. For this reason, the only thing that can provide you with actual long-term outcomes is to convert your unhealthy habits into healthy habits.
Many people who lose a lot of weight on a diet end up regaining it when they avoid dieting. The only thing that can provide you with long-term results is to make permanent lifestyle changes.
There are three major factors that dictate your overall wellbeing, such as diet, physical activity, and genetics. You can manage diet and exercise, but you don’t have manipulation over your genetics, which is believed to be the most important factor. In addition, everyone agrees to that lifestyle changes are important for your overall wellbeing.
