White grain generally refers to refined grains such as white rice, white flour, and white bread that have had the germ and bran removed during processing. These refined grains lack important nutrients like fiber, vitamins, and minerals compared to whole grains. It is recommended to choose whole grains over white grains for better nutritional value.
Of course healthy food has more nutrients. Unrefined foods, such as vegetables, legumes, fruits, and whole grains, have fiber, vitamins, minerals, and phytonutrients that are often missing from refined or "junk" foods like white flour, white sugar, and butter.
The answer is absolutely yes. Refined white flour not only lacks nutrients, but the refinement process also removes all fiber from the grain which allows white flour to be metabolized very quickly. The metabolized carbohydrates from white flour have quite a drastic affected on a person's glycemic response, which in turn does several things. It lowers immune system response, creates inflammation in the body, and disrupts digestion. Consumption of refined grains (particularly white wheat flour) have been found to be linked to many so called "diseases of civilization" such as diabetes, obesity, autism, schizophrenia, depression, chronic inflammatory and autoimmune disease (arthritis, acne, chrones disease, roseacea, etc), irritable bowel syndrome, constipation, diahearra, and the list goes on. But don't just take my word for it, do your own research.
White bread is made from refined flour.
A refined food is a food that has had so much processing done to it that some of it's original nutrients have been lost. For example, wheat is ground into wholemeal flour, which can then be refined into white flour. Here, the germ and fibre are 'lost', diminishing nutrient content.
Unhealthy nutrients are anything artificial, refined, or processed. These include but are not limited to trans fats, sugar, high fructose corn syrup, iodized salt, white flour, anything you cannot pronounce easily, and aspartame. Some would also consider gluten and grains in general to be considered unhealthy, however this is debatable.
white flour
White flour. Enriched flour has had some nutrients added to it, while white flour has been ground and bleached.
Whole grains contain the whole grain kernel (made up of the bran, germ, and angiosperm) instead of having these nutrients stripped off. For example, brown rice is whole grain, and white rice is refined. They are the same type of rice, but white rice has had the outer layers, along with all the nutrients, scraped off. Some examples of whole grains are brown rice, wholewheat flour, Bulgar, oatmeal, and whole cornmeal. Also, anything that has "whole wheat" or "whole grain" on the label.
There is no general answer to this question. Some foods are heavily refined, which removes nutrients from them. Some examples are flours, breads made from refined flour, white sugar, white rice, etc. Other foods may have been grown in soil which does not contain all the nutrients and macro-nutrients, so those foods would be lacking in nutrients. It really depends on how much processing has been done on the food, whether high heat has been used on it, the soil it was grown in, etc.
Whole wheat flour is just that, wheat that is ground into flour with nothing removed. White flour is just the middle part of the wheat kernel without the bran or wheat germ. Enriched flour has vitamins added to it to make up for the bran and wheat germ. Refined could mean any of these other than whole wheat.
