You give no analysis here, just printing this and touting the outcomes. Were you paid by the same people who funded the study? We look to folks like you to help interpret studies. Here's some analysis for the people reading this post:
Small Sample Size: Only 24 participants in the intervention (split across sites with slight method differences), making it a pilot rather than definitive. Subgroup analysis (e.g., per-protocol) further reduces power, risking overinterpretation.
No Control Group: Without a placebo or comparison (e.g., low-vitamin C fruit), it's hard to rule out placebo effects, seasonal changes, or other confounders. Participants knew they were eating kiwifruit for skin health, potentially biasing self-reported or biophysical outcomes.
Short Duration: 8 weeks is brief; longer studies are needed to assess sustained effects or clinical outcomes like reduced wrinkles or better wound healing.
Participant Bias: Mostly middle-aged women with low baseline vitamin C; results may not generalize to younger people, men, diverse ethnicities, or those with adequate vitamin C status (the study excluded high fruit-eaters).
Funding Influence: Partially supported by Zespri International (a kiwifruit marketer), though authors declare no conflicts and claim independent design/analysis. This raises potential bias, as industry-funded nutrition research sometimes favors positive outcomes.
Unexplained Findings: The slight elasticity drop and lack of change in collagen peptides or oxidative stress markers suggest not all skin functions improved uniformly. Ultrasound density is a proxy, not a direct collagen measure, so interpretations rely on assumptions.
Statistical Notes: While p-values indicate significance, effect sizes are moderate, and multiple tests increase false-positive risk without adjustments.
💯. I’d say this is a good start, sound preliminary evidence of kiwifruit’s skin perks via vitamin C, but not a slam-dunk. Larger, blinded, long-term studies without industry ties are needed to confirm the data, For now, it’s safe to say kiwi is a nutrient-dense option for low-vitamin C diets…I try to eat one a day. Time will tell if another non-biased study pops up.

I am so pleased you reported on the efficacy of eating gold kiwi and increased levels of skin Vitamin C. This study emphasizes the need to eat the whole food to get the desired result. You cannot simply dose with Viamin C and expect similar results. Kiwi has numerous antioxidants and phytochemicals and fiber which work in synergy to improve health. This is not news to the Whole Foods Plant-Based world.
Eat whole grains, beans, fruit, nuts, and seeds! Your body will then heal itself.
Kiwi, especially the Sun Gold variety, is very expensive, not to mention the waste when you find that, as soon as you cut into one, that it is spoiled. The Sun Gold variety, in particular, spoils quickly. I used to take it for a digestive ailment but gave up for these reasons. I tried using freeze dried kiwi thinking at least it wouldn’t spoil, but gave that up because I noticed no benefit. Kim currently taking powdered ascorbic acid since, at least, this contains no fillers or additives. I can’t afford fresh kiwi fruit.
Waaay too much sugar - which damage skin and other body tissues though glycation - leading to AGEs, advanced glycation end products: permanent damage.
If we can stop eating long enough to allow our bodies to switch from assimilation of nutrient to repair & maintenance. Then the body can break down damaged tissue, and rebuild, if we consume enough animal protein and fat. Yes, fat. Every cell in our bodies need fat & cholesterol for their structure & function. Nerve sheaths, many hormones, and our brains re made mostly of fat.
Kiwi fruit is also high in oxalates, which bind to minerals making them unavailable, and can create painful kidney stones, or sharp crystals in various parts of the body.
If this "rationale" were true, that is, if it worked and was repeatable, after 40 years of kiwifruit being sold and purchased, the complexions of a good portion of the world's population should be so healthy they glow in the dark...
But it doesn't seem like that at all to me.
Why flaunt a simple possibility, a "rationale" as if it were a certain fact and therefore verifiable over and over again?
This can't be done anymore; I don't expect it from you at the MacCullought Foundation. I didn't believe you continued to spout "rationales" as if they were truth without demonstrating the critical process that should be behind them, in light of so many failures.
Wouldn't it be better to gradually analyze in detail all the failures of foods deemed healthy and healing, including extracts or supplements, starting with those that were most widely distributed based on marketing data, but instead turned out to be mere foods, whose price was even inflated for this reason?
I can give you an example myself: 40 years ago the buzz began that yogurt was good for the intestines. In 40 years, I believe it has been one of the food processing industries that has filled supermarket shelves the most. Well, have you seen progress in people's intestinal health? I haven't, yet the psychosis generated by the deduction that the bacterial flora would improve has been so powerful that it has created a continuous sale of this product for over 40 years in much of the world. This perhaps should be analyzed better... for example, it shows that all or almost all of us are convinced that our intestines have problems, but it also shows that we believe we can solve them with foods that are absolutely not beneficial and unfortunately we always do what everyone else does.

At last something that tastes good, and is good for you! 😹😹
I love the gold kiwi. I germinated some seeds last year and have a few seedlings growing now. I'm hoping that they fruit soon.

Dietary vitamin̈ C: is this a way of on̈ly talking about vitamin̈ C that you get through fruit?
Or do these improvemen̈ts also happen̈ with pure ascorbic açid?
My kidney aches when I take Vitamin C - HOWEVER, I can take Liposomal Vit C without the ache.
I think the question is :where did the vitamin C come from ? corn ?
I am so pleased you reported on the efficacy of eating gold kiwi and increased levels of skin Vitamin C. This study emphasizes the need to eat the whole food to get the desired result.

Are Gold Kiwi GMO? I think they have more sugar than the green ones and I'm wondering if the green ones were studied
true, gold kiwi are a good source of vitamin K and E as well...

The Sun Gold variety, in particular, spoils quickly. I used to take it for a digestive ailment but gave up for these reasons.

Good news, great tasting. :)

Did SunGold finance the study? Only half kidding….
Two questions: Is eating the skin essential to getting the benefit? What is the "green" kiwi equivalent of 2 Sungold kiwis (an estimate will do)?
Uhhhhh…WTF!!! Why didn’t you tell us this before, Nic??
