Danger of eating browned (焦 ) food?

 

TLDR; 

A current food scare is acrylamide found in browned food. Acrylamides has been shown to cause cancer in rats.  But browned foods e.g. freshly baked/roasted food are tasty! Should we avoid them 

and switch to bland steamed/boiled good.

A sensible approach is to eat smartly but not compromise quality of life ascetically. Foods low in sugars and high in antioxidants have lower levels of acrylamide i.e. standard dietary advice.  Eat lots of fruits and vegetables, and don’t eat too much junk food, and thus cross acrylamide off the list of food issues you need to spend much time worrying about.

Long story:

I noticed Jack not eating the brown parts on his naan (Indian bread) in the Indian restaurant. Those were the tastiest parts! It seems a waste of good food to me so I asked him why. He said it's bad for health based on some article.

I recall reading about it: 

certain cooking methods (roasting, baking, etc) of certain foods above 250F for a long time creates certain cancer-causing chemicals called acrylamides. 

Wow! that's scaaaary!  That would mean not eating almost everything that's tasty and restricting food to just boiled or raw food. 250F is low cooking temperature. Many tasty food in a  restaurant or home is at that temperature or with that method. 

It is also counter intuitive to human evolution. Humans learned to eat delicious food from that sweet smell that comes from browning i.e. Maillard reactions.

Since browning food contains acrylamides that causes cancer in rats, are we perversely designed to like food that kills us? What an affront to Intelligent Design!

My view:

1. the FDA does not recommend that we change our diet drastically because of the acrylamide scare in food. Instead, go for a balanced healthy diet 

2. acrylamide studies are done on non-humans (rats) at very high doses:

    a. rats are not humans and humans do not have the same reaction as rats to certain chemicals

    b. acrylamide doses in the studies are much higher than what humans normally consume. 

3. 99% of humans have acrylamides in their bodies already! 

4. Acrylamide formation need many conditions including asparagine (potatoes, wheat etc. i.e. not all food have asparagine), temperature, heat, frying oil, food        additives/seasoning, water content in food etc. In other words, browned food does not equal elevated acrylamide levels

5. Blanching (soaking food e.g. potatoes in boiling water for a short time)  before frying reduces acrylamides. Fortunately, many Chinese restaurants does it. I also do that at home to reduce frying times

6. reduce sugars when cooking. The standard cooking practice of adding sugar last before cooking helps. 

7. Limit use of microwave oven. Microwaving potatoes produces more acrylamides than frying!

8. Boiling/steaming vegetables for a short time cuts down on acrylamides production

Common sense

Foods low in sugars and high in antioxidants have lower levels of acrylamide i.e. standard dietary advice.  Eat lots of fruits and vegetables, and don’t eat too much junk food, and you can cross acrylamide off the list of food issues you need to spend much time worrying about.

http://www.thebeijinger.com/forum/2008/08/25/The-best-national-anthem

1. Italy "Fratelli D'Italia"

No doubt in my mind. I love a good march and this is so catchy and
full of energy. I love how it is divided into several great parts and
how you can scream your way through the ending. Goosebumps every time.
Love it so much that I've even taught myself the lyrcis.

2. Russian Federation "Hymn of the Russian Federation"

You can say what you want about the former communist east but they
sure knew how to put a great anthem together. You all know this one so
I am moving on. A close second.

3. The Netherlands "Het Wilhelmus"

A more low key anthem but I think it's beautiful. Not so much energy in this one but lots of emotion,, I really like it.

4. Peoples Republic of China "March of the Volunteers"

Another good march in 4th place. Nice classical music with a few
distinct Chinese traits. Very recognizeable and catchy and it offers a
nice powerfull ending.

5. Sweden "Du gamla du fria"

Now that my Swedish brothers failed to win a gold in Beijing (sorry,, being Danish I had to comment on that
) we didn't get the chance to hear their very emotional and quite
beautiful anthem. I hate to say it but I like theirs much better than
the Danish one.

Bad national anthems? there are probably a lot but I wouldn't know
or remember them. Never really enjoyed "God Save the Queen",, too
pompous and royalistic and the lyrics are kinda boring imo. "Star
Spangled Banner" isn't half bad but not in my top 5. Jamaicas anthem is
pretty good having heard it a couple of times lately.

The United States anthem is difficult as a song (musically
speaking), too many leaps in tone which, on the bright side, leads to
moments like this

Squaring Box Corners for Gluing

Whenever I'm assembling a box or drawer, I feel like I need two pairs of hands - one to hold the assembly square and another to apply the clamps. To make things a little easier, I came up with some squaring blocks to help hold the pieces square while I clamp them together. I made my squaring blocks out of plywood. The base is just a square piece of 3/4" plywood. The top layer is actually made up of three separate pieces of plywood, see detail drawing at right. The trick is to glue these three pieces down squarely to the base so that the space in between them matches the thickness of the workpieces you are clamping up. To use the squaring blocks, simply place one under each corner of the assembly before clamping the pieces together. Have a good weekend, Phillip Huber Online Editor, ShopNotes

Instructions on Using SystemRescueCD to copy files from dead PC to another HD (TARGET)
---------------------------------------------------------------------------------------
1. Find out where things are first
fdisk -l

2. create (readonly) mount for source (PC)
mkdir /PC
mount -t ext3 /dev/sda5 /PC -ro  (LINUX)
mount -t ntfs /dev/sda1 /PC -ro  (WINDOWS)
cd /PC
ls -alh

3. create mount for HDD target

/mnt/ntfs/Documents and Settings/

If you want to edit some Windows files, then you need to use the NTFS-3G driver:

mkdir /TARGET
% ntfs-3g /dev/sdb1 /TARGET

cd /TARGET
cp /PC/whatever .
