Nutrition researchers continue to discover how antioxidants protect our health. These substances stop, and sometimes even repair, damage to cells that can occur from highly reactive molecules. Called free radicals, these molecules are generated naturally by many life processes (like breathing) and daily exposures (like sunlight). By preventing this damage, scientists say antioxidants can help prevent cancer, heart disease and other health problems, such as age-related eye diseases, for example, macular degeneration.

But these discoveries should not lead us to focus only on famous antioxidants, like vitamins C and E. A new study supports the advice of health organizations, including the American Institute for Cancer Research, that vegetables and fruits are preferable to supplements for harnessing antioxidant power.

More protection from fruits and veggies

In this recent study, participants ate the same basic diet that excluded all vegetables and fruits. One group, however, was also given about six servings of fruits and vegetables a day. A second group received a vitamin and mineral supplement in place of the vegetables and fruits. Before and after the 25-day program, researchers tested the participants for their levels of oxidation damage, as well as antioxidant nutrients and defense systems.

This study indicates that vegetables and fruits provide more antioxidant protection than supplements alone. The group that ate vegetables and fruits showed significantly less oxidation damage than the others. The group that took supplements showed a reduction in oxidation damage, but not as much. Levels of an enzyme system vital for antioxidant defense increased only in the group eating fruits and vegetables. The researchers concluded that vegetables and fruits offer sources of antioxidant protection not available from vitamin and mineral supplements alone.

In an earlier study, participants who had been eating an average of five servings of fruits and vegetables per day over the previous year were put on a diet that maintained their starting weight, but increased fruits and vegetables to a total of ten servings a day. Their antioxidant intake and antioxidant capacity measured by blood tests increased substantially. The researchers believe the increase in antioxidant power probably came from more antioxidants, like beta-carotene, lycopene and vitamin C, as well as more flavonoids and other phytochemicals that act like antioxidants. They also observed that the body’s antioxidant capacity seemed to level off at about ten to twelve fruit and vegetable servings a day.

Phytochemicals also important

While research shows that vegetables and fruits are vital sources of antioxidants, the plant-based diet recommended by the American Institute for Cancer Research is the most complete approach to healthy eating. Whole grains, beans and nuts also contain antioxidant vitamins and phytochemicals. Spices and herbs add even more.

It cannot be stressed enough that antioxidants are only part of the health benefits of a plant-based diet. Nonantioxidant properties of phytochemicals are another important part. For example, test tube studies at Cornell University ranked the ability of different vegetables to control the growth of one type of cancer cell. The results differed from the vegetables’ antioxidant content, probably reflecting the additional anti-cancer effects of phytochemicals.

To obtain phytochemicals – hundreds of which are known to exist – you need to eat a wide variety of vegetables, fruits, whole grains and beans. This is a major reason why supplements can’t supply the benefits of a plant-based diet.


I've always had this question in my mind whether vitamins alone can supplement a healthy lifestyle. Now I understand the power of food.

Yeah - I have found the subject of phytochemicals extremely interesting - they are apparently the parts of food which prevent against cancer, heart disease etc, perhaps to an even greater extent than vitamins and minerals.

However, I don't really see what this has to do with acne! :mrgreen:

The fact that food is a better source for vitamins, minerals, and anti-oxidants than buying supplements means that we can improve our health or particulary our skin health just through food consumption. This means that we can speed up the time necessary to make our skin heal faster and this includes combatting acne.

I take two multi-vitamin packs a day. Now I know that if I eat 5-10 servings of vegetables and fruit, I would not need to take any mutli-vitamins and I would have more anti-oxidant protection and more vitamins to help my body do what it needs to do..

However, bear in mind that vitamin/mineral supplements may still have a place:

leaching of minerals from soil due to over cultivation may have lead to a decrease in the amount of certain minerals avaliable in food.

certain vitamins are sensitive to storage/heat/processing, and their amounts maydecrease between the time the fruit/vegetable is picked and you buy it at the supermarket.

99.5% Clear (skin gets 'congested' PMS week, but no actual breakouts)


Fragrance-Free Baby Wipes + a few drops Rimmel Makeup Remover solution

3/4 AHA Toner* & 1/4 Glycerin (cotton pad) -- good toner, moisturizer, and makeup base (use less glycerin if not under makeup)

Occasional Treatments (2-3x/week): Exfoliating bp wash* in shower, 2.5% bp lotion* at night

CoverGirl TruBlend Powder Foundation


* = Klear Action Kit (Pro-Activ knockoff)


Gluten-free diet (for non-acne reasons, but it seems to have cleared my acne)

We can absolutely get nutrients from foods, but we do have to remember that if the soil isn't enriched or lacks certain nutrients, those fruits and vegetables won't have (as much of) it either. Not to mention, if you cook foods (regardless of the method), you deplete (and can alter) certain nutrients. I suppose that's why the raw diet is a big thing. They say that if bugs will eat it, then it's good for us too. I just don' bugs ;-)

These are not steps, but stages some people progress through when going from conventional to holistic medicine. Stage 2 is how I became 99%+ Clear, eliminated my dysmennorhea, significantly reduced my sebum & pore size, etc & is my predominant method.

Stage 1 (Treatment):

* (Daily) Isocare Skin Control Cleanser, Dream Products Customized Natural Face Lotion & Coppertone Sport Spray Sunscreen (mixed)

* (Sporadically) spot treat w/ anti-inflammatory (neosporin, hydrocortisone, salicylic acid) or a skin lightener (post-inflammatory pigmentation) to treat stubborn cystic/nodular acne that appears due to unknowingly or knowingly ingesting a food/ingredient that breaks me out (I do my best to avoid these foods). If you cover treated area w/ a bandaid, it makes product more effective.

Stage 2 (Prevention): "cheapest" method ~ Since Aug. 2002

* Follow a Gluten-Free, Trans-Fat Free, Dairy-Free and No Added Sugar diet for my Insulin Resistance/Hyperandrogenism (Silent Chronic Inflammatory Syndrome)

* Avoid ALL types of nuts and the Genus Prunus (almonds, plums, peaches, nectarines, apricots, cherries), Bananas, Pineapples, Cottonseed oil, Artificial Sweetners.

Stage 3 (Correction):

* Strengthen/Repair GI - Immune health


* Developing functional foods for those with acne & other special needs (assuming there's a defficiency).

* Developing good & "safe" formulas for various hormonal issues for women. Correction stage may resolve this for some.
