Do you see everyone talking about Korean skincare and often think what the hype is about?
Do you come across the 10-step Korean skincare routine on the internet and wonder if it makes sense?
Well, K-beauty has become the new buzz word in skin care products for various reasons. It’s not only popular in Asia but is among the top 10 beauty markets in the world.
Bran. This is the hard, outer shell. It contains fiber, minerals, and antioxidants.
Endosperm. The middle layer of the grain is mostly made up of carbs.
Germ. This inner layer has vitamins, minerals, protein, and plant compounds.
Grains can be rolled, crushed, or cracked. Nonetheless, as long as these three parts are present in their original proportion, they’re considered whole grains.
Refined grains have had the germ and bran removed, leaving only the endosperm.
Though enriched refined grains have had some vitamins and minerals added back, they’re still not as healthy or nutritious as the whole versions.
Products made from these foods are considered whole grain. These include certain types of bread, pasta, and breakfast cereals.
When you purchase processed whole-grain products, read the ingredient list to make sure they’re made entirely from whole grains, not a mixture of whole and refined grains.
Also, keep an eye on the sugar content, especially in the case of breakfast cereals, which are often loaded with added sugar. Seeing “whole grain” on the packaging does not automatically mean that the product is healthy.
SUMMARYWhole grains contain all three parts of the grain. There are many different kinds, including whole wheat and whole corn, oats, brown rice, and quinoa.
1. High in nutrients and fiber
Whole grains deliver many important nutrients. These include:
Fiber. The bran provides most of the fiber in whole grains.
Vitamins. Whole grains are particularly high in B vitamins, including niacin, thiamine, and folate (3, 4).
Minerals. They also contain a good amount of minerals, such as zinc, iron, magnesium, and manganese.
Protein. Whole grains boast several grams of protein per serving.
Antioxidants. Many compounds in whole grains act as antioxidants. These include phytic acid, lignans, ferulic acid, and sulfur compounds (5).
Plant compounds. Whole grains deliver many types of plant compounds that play a role in preventing disease. These include polyphenols, stanols, and sterols (6).
The exact amounts of these nutrients depend on the type of grain.
Nevertheless, to give you a sense of their nutritional profile, here are the key nutrients in 1 ounce (28 grams) of dry oats (4):
Fiber: 3 grams
Manganese: 69% of the Reference Daily Intake (RDI)
Phosphorous: 15% of the RDI
Thiamine: 14% of the RDI
Magnesium: 12% of the RDI
Copper: 9% of the RDI
Zinc and iron: 7% of the RDI
SUMMARYWhole grains deliver a variety of important nutrients, including vitamins, minerals, protein, fiber, and other healthy plant compounds.
2. Lower your risk of heart disease
One of the biggest health benefits of whole grains is that they lower your risk of heart disease, which is the leading cause of death worldwide (7).
A review of 10 studies found that three 1-ounce (28-gram) servings of whole grains daily may lower your risk of heart disease by 22% (8).
Similarly, a 10-year study in 17,424 adults observed that those who ate the highest proportion of whole grains in relation to their total carb intake had a 47% lower risk of heart disease (9).
Researchers concluded that heart-healthy diets should include more whole grains and fewer refined grains.
Most studies lump together different types of whole grains, making it hard to separate the benefits of individual foods.
Still, whole-grain breads and cereals, as well as added bran, have been specifically linked to reduced heart disease risk (8).
SUMMARYEating whole grains may lower your risk of heart disease, especially when they replace refined grains.
Whole grains may also help lower your risk of stroke (10).
In an analysis of 6 studies in nearly 250,000 people, those eating the most whole grains had a 14% lower risk of stroke than those eating the fewest (10).
Furthermore, certain compounds in whole grains, such as fiber, vitamin K, and antioxidants, can reduce your risk of stroke.
Whole grains are also recommended in the DASH and Mediterranean diets, both of which may help lower your risk of stroke (11).
SUMMARYAs part of a heart-healthy diet, whole grains may help lower your risk of stroke.
4. Reduce your risk of obesity
Eating fiber-rich foods can help fill you up and prevent overeating. This is one reason high-fiber diets are recommended for weight loss (5).
Whole grains and products made from them are more filling than refined grains, and research suggests that they may lower your risk of obesity.
In fact, eating 3 servings of whole grains daily was linked to lower body mass index (BMI) and less belly fat in a review of 15 studies in almost 120,000 people (12).
Another study reviewing research from 1965 to 2010 found that whole-grain cereal and cereal with added bran were associated with a modestly lower risk of obesity (13).
SUMMARYDecades of research suggest that whole grains are linked to a lower risk of obesity.
5. Lower your risk of type 2 diabetes
Eating whole in place of refined grains may lower your risk of type 2 diabetes (14).
A review of 16 studies concluded that replacing refined grains with whole varieties and eating at least 2 servings of whole grains daily could lower your risk of diabetes (15).
In part, this is because fiber-rich whole grains can also help with weight control and prevent obesity, a risk factor for diabetes (16).
Moreover, studies have linked whole grain intake to lower fasting blood sugar levels and improved insulin sensitivity (17).
This could be due to magnesium, a mineral found in whole grains that helps your body metabolize carbs and is tied to insulin sensitivity (16).
SUMMARYFiber and magnesium are two nutrients in whole grains that help lower your risk of type 2 diabetes.
6. Support healthy digestion
The fiber in whole grains can support healthy digestion in various ways.
First, fiber helps give bulk to stools and lowers your risk of constipation.
Second, some types of fiber in grains act as prebiotics. This means they help feed your beneficial gut bacteria, which are important for digestive health (5, 18).
SUMMARYDue to their fiber content, whole grains help support healthy digestion by giving bulk to stools and feeding your beneficial gut bacteria.
7. Reduce chronic inflammation
Inflammation is at the root of many chronic diseases.
Some evidence suggests that whole grains can help reduce inflammation (19).
In one study, women who ate the most whole grains were least likely to die from inflammation-related chronic conditions (20).
What’s more, in a recent study, people with unhealthy diets replaced refined wheat products with whole wheat products and saw a reduction in inflammatory markers (21).
The results of these and other studies support public health recommendations to replace most refined grains with whole grains (22).
SUMMARYEating whole grains regularly could help lower inflammation, a key factor in many chronic diseases.
8. May reduce your risk of cancer
Research on whole grains and cancer risk have provided mixed results, though they show promise.
In one review of 20 studies, 6 showed a reduced risk of cancer, while 14 indicated no link (23).
Current research suggests that whole grains’ strongest anticancer benefits are against colorectal cancer, one of the most common types of cancer (24, 25).
Additionally, some health benefits linked to fiber may help lower your risk of cancer. These include its role as a prebiotic (24, 26, 27).
Lastly, other components of whole grains, including phytic acid, phenolic acids, and saponins, may slow the development of cancer (24).
SUMMARYWhole grains may help prevent colorectal cancer, one of the most common types of cancer. Still, research on whole grains’ anticancer effects is mixed.
9. Linked to a reduced risk of premature death
When your risk of chronic disease is reduced, your risk of dying prematurely also goes down.
In fact, one study suggested that whole grain intake specifically lowered the risk of dying from heart disease, as well as any other cause (28).
The study used data from two large cohort studies, adjusting for other factors likely to influence death rates, such as smoking, body weight, and overall eating patterns.
Results indicated that every 1-ounce (28-gram) serving of whole grains was linked to a 5% lower risk of death (28).
SUMMARYWhole grains are linked to a lower risk of dying prematurely from any cause.
Whole grains are not for everyone
While whole grains are healthy for most people, they may not be appropriate for all people at all times.
Celiac disease and gluten sensitivity
Wheat, barley, and rye contain gluten, a type of protein that some people are intolerant or allergic to.
Having a gluten allergy, celiac disease, or gluten sensitivity can cause a range of symptoms, including fatigue, indigestion, and joint pain.
Gluten-free whole grains, including buckwheat, rice, oats, and amaranth, are fine for most people with these conditions.
However, some have difficulty tolerating any type of grain and experience digestive distress and other symptoms.
Irritable bowel syndrome
Some grains, such as wheat, are high in short-chain carbohydrates called FODMAPs. These can cause symptoms in people with irritable bowel syndrome (IBS), which is very common.
SUMMARYSome people have difficulty tolerating grains. The most well-known issue is gluten, which affects people with gluten allergy, celiac disease, or gluten sensitivity.
How to incorporate whole grains into your diet
You can incorporate whole grains into your diet in many ways.
Perhaps the simplest thing to do is to find whole-grain alternatives to refined grains in your diet.
For instance, if white pasta is a staple in your pantry, replace it with a 100% whole-wheat or other whole-grain pasta. Do the same for breads and cereals.
Swap out white rice with brown rice, or for a different whole grain like quinoa or farro.
Add barley to vegetable soups.
Try using whole-grain flours, such as whole-wheat pastry flour, in baking.
Use stone-ground corn tortillas rather than white tortillas in tacos.
SUMMARYThere are many ways to work whole grains into your diet. Replacing refined grains with whole grains is a good place to start.
The bottom line
Whole grains deliver a variety of health benefits.
Regularly eating whole grains may reduce your risk of heart disease, type 2 diabetes, and obesity. This is particularly true when they replace the refined grains in your diet.
High-fiber foods like whole grains also significantly improve your digestive health, though people with gluten intolerance must avoid wheat, barley, and rye.
For improved health and longevity, consider adding whole grains to your diet every day. Healthy, whole-grain breakfast cereals, such as steel-cut oatmeal, are a popular choice.
Whether you’re travelling for pleasure or for business, following the right dining etiquettes of the country you go to is extremely important. Why? It shows you’re polite and you’re respectful of their culture, which helps you climb a lot of stairs on your social ladder.
If you’re travelling to East Asia soon, and don’t want to walk on cultural eggshells, read this blog to learn the most important eating etiquettes you need to follow when dining in Korea, China and Japan.
Korea
Let’s begin with the country that’s making a huge impact on the world’s cultural scene these days. If you’re one of the many who can’t wait to visit Korea and try the Korean BBQ, then this guide will be very helpful.
Imagine you’re going out to eat at a Korean restaurant accompanied by an older person, don’t take a seat at the table before they do! And also wait till they’ve started eating or picked by their spoon before you dig into your meal.
Moving on, during the meal, if you feel the need to blow your nose (Korean food sure is spicy), make sure you excuse yourself to another room, using a tissue at the table is considered rude because it spreads germs. Moreover, eat slowly and put your chopsticks back on the table once you’re done. Ensure they’re not sticking straight up in your bowl as that’s considered as a sign of bad luck.
Japanese
One of the most important things to keep in mind while dining in Japan is, to wait for the signal of the eldest person to start. Before you dig into your meal, make sure you thank the host for the meal. Similar to the Korean culture, you’re always supposed to keep your spoon or chopsticks straight on the table when you’re not using them.
It’s also common to see Japanese people pick up their bowls, close to their mouth when eating, but you should never raise the food above your mouth!
Chinese
Finally let’s talk a bit about how to eat in China. First, make sure you’re always on time and that you’re well-dressed. Again, seating is an important component of Chinese dining. The most senior person takes the seat furthest from the entrance. And you’re not supposed to start eating until they have done so.
One unique thing about China is that, you’re supposed to wash all your dishes before you start eating. You’ll have a cup, bowl and a small saucer at your placemat along with a spoon and chopsticks. All you need to do is drain hot water or tea over your utensils and dishes, swirl it and empty it out in the larger dish on the table.
