Acidic Food Cause Aging?

The key to having healthy skin lies with what I eat. Cliche as it may sound but the adage, “we are what we eat” is indeed true. So instead of reading materials that only suggest beautifying our skin with external aids like creams and lotions, I’ve begun to read books on how to eat for healthier skin. Two books that I’m currently reading are “The Healthy Skin Diet” by Karen Fisc and “Stop Aging, Start Living” by Jeanette Graf, M.D. with Alisa Bowman.
Both books were randomly picked from the library shelves but coincidentally, they both dealt with the same topic – balancing the body’s pH with alkalizing foods to maintain healthy skin. As I read on, I realized this balance is crucial and has direct connections to what I was trying to achieve with my detox to maintain a healthy liver and a digestive tract. In fact, all the topics that I’ve written before about sleep, caffeine, exercise, diet, stress, and hormones were basically about balancing our body’s pH but I never knew it. So you can say that reading about this was definitely an Eureka moment for me!
Optimal pH level should be slightly alkaline
I’m not about to reproduce the contents of the books here but in a gist, both books suggest that we need a slightly alkaline pH level for optimal health and functioning. On a scale of 1 to 14 and 7 being neutral, our blood should be slightly alkaline at a pH of 7.365 to be precise. If our blood pH becomes too acidic, it can damage the cells and tissues in our body. And in terms of our skin, except for our epidermis that function best at a slightly acidic pH of 5.4 to kill bacteria, cells in the dermis function best at an alkaline pH of 7.35. An acidic pH level can reduce the amount as well as quality of collagen and elastin being produced, thereby causing us to end up with premature aging and wrinkles. In addition, too much acids in the body can also cause demineralisation, which can lead to dry and cracked skin, fingernails that split easily plus thin, brittle hair. Finally, an acidic pH level will damage our red blood cells and this in turn can cause our skin to look dull and greyish from low oxygen supply.

Acid forming foods
When our body has too much acid, we may develop symptoms of acidosis, such as lethargy, poor digestive system, constipation, acne, skin bumps, skin allergies and so on. Causes for this include too much stress, alcohol, smoking, chemicals, dehydration and most importantly, a poor diet consisting of acid forming food. And what are acid producing foods? Common ones include meat, sugar, cereals, as well as processed foods. However, the interesting information I picked out was that a food that is considered as acidic may actually be alkaline when eaten. For instance, oranges, lemons, and limes are considered acidic, but the end-product is an alkaline residue. Dairy products and meats usually test alkaline before digestion and assimilation, but actually leave acidic residue when ingested. You can run a search on the Net to look for acidic/alkaline food chart but here is one that I found with a rather detailed listing.
Testing pH level in your body
You can actually test your body’s pH level by using pH test strips to test your urine continuously for five days in the mornings but a more accurate reading is to have a doctor measure your blood’s pH level. And the trick to the whole issue is to achieve a balance, which I consider tough. I’ve learnt that we can still eat acidic food in moderation but my experience tells me otherwise. Some weeks ago, I drank some beer and immediately felt so lethargic the day after. So for some foods, abstinence is possibly the best solution.
Remedies to release acids in the body
Two good remedies I found that can help our body release acids: one is to take a warm glass of lemon drink in the morning, which is also good to cleanse the liver and the other is to engage in moderate exercise for about 20 to 30 minutes a day. Anyway, I’m going to come out with a plan to do this right for myself. I have a lot of information swirling within my head at the moment and I need to sieve them through. But going with my initial thoughts, I think my plan is going to be a long one and it will need some time to materialize. So if you’re interested, stay tuned.

Excessive Exercise ! Good or Bad ?


A   new study  has found that strenuous, long-term exercise may have anti-aging properties by virtue of its effect on telomeres.


Exercise may have beneficial properties at a chromosomal level, specifically on telomeres, the ends of chromosomes that are believed to have an impact on aging.

What are telomeres ? 
 A telomere is a region of repetitive DNA sequences at the end of a chromosome, which protects the end of the chromosome from deterioration or from fusion with neighboring chromosome

Telomeres have been compared with caps on the ends of shoelaces, protecting against genetic unraveling, which, in turn, can lead to diseases.
When telomeres become too short after repeated cell divisions, cells die.

 As people get older, telomeres get shorter.

The study found an association between telomere length and leisure time exercise. It concluded that a sedentary lifestyle may accelerate the aging process as the result of telomere shortening.


Too Much Exercise cause Aging?

'Excessive exercise promotes the biological aging of middle-aged women'
according to Shin Yun-a, professor of physical education at Seoul National University.
Heavy exercises consume more oxygenShin released a paper regarding the effect of heavy exercise on middle-aged women’s telomeres, an aging indicator in cells and discovered telomeres got shorter when women in middle age in their 30s to 60s do excessive exercise. According to her, sudden and heavy exercise requires excessive oxygen consumption, causing aging.
Shin explained that after heavy exercise, the women’s lipid peroxidation, that damage cells, rapidly increased. Excessive exercise also caused superoxide dismutase (SOD) deactivation — SOD is an enzyme protecting cells against aging.
Free radicals cause cellular damageAnother article at the Department of Physiology in the University of Valencia also stated that exercise causes an increase in the generation of free radicals by cells and these radicals cause cellular damage.   However, this is only when exercise is exhaustive as strenous exercise causes oxidation of glutathione, release of cytosolic enzymes, and other signs of cell damage.
Antioxidant supplements can helpThe same article pointed out that the damage can be prevented by antioxidant administration and this is similar to what I read in Men’s Health Magazine, which encouraged those who exercise to supplement with antioxidants (vitamins A, C & E) in order toreduce the post-workout infllamtion.  Definitely something to consider, especially for those who exercises regularly.
So if you exercise, do exercise in moderation as well.

Vitamin C and E to fight aging


The two key sources of antioxidants are water soluble vitamin C and fat soluble vitamin E. Vitamin E is the most efficient antioxidant and is also the most abundant in our diet. It is the one you need the less of.



Antiaging antioxidant, Vitamin C being water soluble requires more and heftier intake as, unlike antiaging antioxidant vitamin E, the body cannot store it for long periods of time and needs to be replenished. This is where multi vitamins and supplements of vitamin C together with raw fruits and vegetables is important to top up our daily intake of vitamin C. Vitamin C is also excellent at fighting against the effect of free radicals created from smoking and pollution.

Most skin creams actually contain vitamin E. It’s listed on the label as alpha-tocopheryl acetate. This form of vitamin E is useful because it doesn’t get oxidized. That’s actually good because the alpha-tocopheryl acetate can penetrate through the skin surface and get to the living cells. About 5% of the amount that's smeared on the skin is actually converted to the free tocopherol once it’s inside those deep skin cells and provides beneficial antioxidant effects.

Synthetic vitamin E is cheaper than d-alpha-tocopherol, or natural source vitamin E, but only half as effective. The body is clever enough to figure out the one it wants. It’s really a wash. If you want to get 200 IU of natural vitamin E, you can buy 400 IU supplements of synthetic vitamin E at maybe half the cost of 200 IU natural vitamin E.
