Tinh chất gạo lứt (Stabilized Rice Bran): một "siêu thực phẩm" In Email

Stabilized Rice Bran là gì (SBR - tạm dịch ra tiếng Việt là tinh chất của gạo lứt). Chắc hẳn bạn sẽ ngạc nhiên nếu biết SRB là lớp cùi bao bọc bên ngoài hạt gạo lứt, được bóc tách và xử lý công nghệ bằng công nghệ chống phân hủy. Nếu không được xử lý, lớp cùi giàu vi chất dinh dưỡng quý giá sẽ phân hủy rất nhanh và trở thành cám có mùi ôi khét. Bao nhiêu lâu nay nhân loại đã không hiểu và bỏ phí mất một nguồn thực phẩm tự nhiên "siêu dinh dưỡng" từ lớp cùi - tinh chất quý nhất của gạo lứt. Khoa học gần đây đã chứng minh giá trị dinh dưỡng đặc biệt của SRB và phát hiện ra rằng chính lớp cám là nguồn cung cấp chính cho những tác dụng tuyệt vời của hạt toàn phần và gạo lứt.

Nếu bạn tìm kiếm trên Google với từ khóa "Stabilized Rice Bran" và "whole grains", bạn sẽ thấy rất nhiều thông tin về tác dụng kỳ diệu của nó và những hợp chất quý giá mà nó chứa đựng, nhiều hơn bất kỳ loại thực phẩm nào mà bạn từng biết.  

Rất giản dị nhưng để sử dụng được nó thì không đơn giản chút nào vì nếu tách khỏi hạt, cám phân hủy rất nhanh và cần phải được xử lý bằng công nghệ đặc biệt. Sau quá trình xử lý, cám gạo được ổn định và gọi là SRB. Tùy công nghệ mà có thể giữ lại cám gạo gần như nguyên vẹn sau khi xử lý. Vì thiếu thông tin, thiếu công nghệ xử lý và chưa hiểu rõ tác dụng và giá trị của SRB mà chúng ta đã bỏ phí một nguồn siêu thực phẩm quan trọng hoặc dùng nó vào những việc không đúng với giá trị thật sự. Có rất nhiều nghiên cứu khoa học đã tìm ra mối liên hệ giữa SRB và khả năng phòng chống, giảm nguy cơ các bệnh tiểu đường, tim mạch, ung thư... Đã đến lúc chúng ta cần suy xét lại một cách nghiêm túc về việc cần phải bổ sung SRB vào bữa ăn hàng ngày để thay thế cho việc dùng thực phẩm hạt toàn phần (gạo lứt) vốn không thể áp dụng một cách rộng rãi trong cả cộng đồng.

Sau đây là một bài giới thiệu về SRB trên trang web của Nutracea, một công ty sản xuất SRB hàng đầu của Mỹ.

Stabilized Rice Bran Super Food

For Your Total Health



Stabilized rice bran is the new natural health super food! Rice bran contains an amazing number of advanced nutrients and antioxidants which help you maintain your overall health. The nutritional value of rice bran is phenomenally superior to other brans and works with your body naturally for optimal total health benefits.

Stabilized rice bran has over 100 antioxidants & co-factors  which means it contains all the essential vitamins and minerals you would ever need for natural health maintenance, daily nutrition, fitness, weight management and instant energy for your healthy lifestyle.

Rice bran doesn't stop there —it also contains an astounding quantity of other healthy nutrients such as phytosterols, polysaccharides, carotenoids, natural fiber, Vitamin E complex, plus a large complement of B vitamins.

Rice bran boasts an array of essential vitamins and minerals including potassium, calcium, magnesium, iron, phosphorus, zinc and gamma oryzanol (only found in rice bran), plus it is packed full of omega-3 & omega-6 fatty acids.

The Rice Bran Issue

Rice Bran KernalHowever, there is a natural enzyme called lipase in the rice bran that causes the oil to become rancid. When the rice is growing, the lipase and the oil are isolated from each other, in separate types of cells. However, as soon as any mechanical processing occurs - such as when the rice is hulled or when the bran is removed from the kernel in the process of "polishing" white rice - the cell walls are ruptured and lipase meets rice bran oil. From there it only takes a few hours for the fragile components of the oil to become oxidized and rancid.

The problem with rice is that the brown part (the bran) contains oil which is very prone to rancidity, occurring within a few hours. The stabilization process deactivates lipase, the enzyme found in rice bran that causes the fat to spoil and stops this rancidity from happening.

So What Can Stabilized Rice Bran do for Me?

Well, let's start with rice bran's super antioxidants, particularly the special vitamin-E complex (which is only found in rice bran, barley and palm oil). Stabilized rice bran is the source of a newly discovered complex of vitamin-E and tocotrienols, along with tocopherol the compound generally called vitamin-E. The tocotrienol compounds are 40-60 times more potent as antioxidants.

Antioxidants are the vital nutrients which fight off free radicals in our bodies. Free radicals cause premature aging and many of the degenerative diseases of old age. Rice bran contains over 100 of these antioxidants & co-factors to help keep you young, maintain your health and supply your body with more than its daily nutritional needs.

Now, let's look at another special element of stabilized rice bran called lipoic acid. Lipoic acid is an advantageous compound for producing energy in muscles and is another important part of the antioxidant system. Lipoic acid directs calories into energy production and away from fat production. Lipoic acid is known as the "universal antioxidant" that directly and indirectly helps protect every body component from the damage of oxidative stress.

Rice Bran Studies

Stabilized Rice bran is continually being tested and so far it has displayed great promise in the use against a myriad of modern diseases, including arthritis, joint health, peripheral neuropathy, cardiovascular disease, high cholesterol and diabetes*. Rice bran's naturally filling fiber content can also aid as a healthy weight loss supplement in the fight against obesity.

From the most recent Rice Bran Studies, rice bran certainly has earned the accolade of a true natural health super food! Rice bran is the single most nutrient rich food source there is.

Rice Bran OR Vitamins?

Most vitamins you would buy today are synthetic (not natural) and these types of vitamins could possibly do more damage to your body than good. When taken separately, vitamin supplements are not as readily available in the body as are the vital nutrients & natural antioxidants in rice bran.

Why?

It is a well established fact that a soluble powder (ability to dissolve in liquid) is more readily distributed and digested in your body; along with its almost immediate availability of vital nutrients to your body, when compared to a vitamin pill and/or capsule (The Physician's Desk Reference shows that vitamins and minerals in a pill form are only 10% to 20% absorbed by the body).

This is called Bioavailability and refers to the availability of nutrients to your body on a cellular level. Nutrients that are bioavailable are naturally absorbed into your system very quickly (unlike synthetic vitamins), digested and then distributed to the various parts of the body where they are required to support total health, increased immunity and disease prevention.

Which means that Rice Bran can be more efficient, with less waste, in the distribution of it's vital nutrients and antioxidants to your body than vitamins.

Where Has Stabilized Rice Bran Been all my Life?

Thrown away, is the sad answer to that, or used for things other than supplying nutritional supplements and nourishing people. Rice bran is one of, if not the, biggest squandered food resource in the world. Rice bran is the brown part of the rice kernel, the part which is discarded to make the white rice that most of us consume. All around the world rice bran has been used for burning as fuel and/or dug back into the soil.

I Eat Rice - Don't I get my Rice Bran that Way?

Sorry, but no. Eating brown rice might give you more fiber. The bad news is that most of the essential nutrients, vitamins and minerals plus the potent antioxidants found in rice bran are denatured during processing. Rice bran products are whole foods in themselves. This is basically concentrated brown rice, without all the white carbohydrate eaten with a rice-based meal.

What Does Stabilized Rice Bran Mean?

The problem with rice is that the brown part (the bran) contains oil which is very prone to rancidity, occurring within a few hours. The stabilization process deactivates lipase, the enzyme found in rice bran that causes the fat to spoil and stops this rancidity from happening.

This enables rice bran to be made into a various number of natural health products for you.
