Your body is in a constant state of renewal. Every 35 days, your skin completely regenerates, shedding old cells and replacing them with new ones. This means that the food you consume quite literally becomes part of who you are. The saying “you are what you eat” is more than just a catchy phrase—it’s a biological fact.
But what does this mean for your health? How can you make sure your body is rebuilding itself with the best possible materials? Let’s dive into the fascinating world of cellular regeneration, nutrition, and how your diet directly influences your body’s renewal process.
Your Body Is Constantly Rebuilding Itself

Many people think of their body as a static entity, but in reality, it is continuously changing. Cells die and new ones take their place in an ongoing cycle of renewal. Different tissues regenerate at different rates, and some renew more frequently than others.
How Often Does Your Body Replace Cells?
Here’s how long it takes for different parts of your body to regenerate:
- Skin: Every 35 days, you get completely new skin cells. This is why wounds heal, and why skincare routines can have long-term effects.
- Stomach Lining: Every 2-3 days, your stomach regenerates its lining to protect itself from harsh digestive acids.
- Liver: The liver, an essential detox organ, regenerates every 5 months, allowing it to recover from damage if given the right nutrients.
- Red Blood Cells: These cells last about 120 days before being replaced with fresh ones.
- Bones: Your skeleton renews itself every 10 years, replacing old bone with new, stronger tissue.
Since your body is constantly replacing old cells with new ones, the quality of these new cells depends on what you feed them.
The Impact of Nutrition on Cell Regeneration
Everything you eat contributes to the raw materials your body uses to create new cells. This means that poor nutrition can lead to weak or unhealthy cells, while a nutrient-rich diet helps your body regenerate with strength and vitality.

Essential Nutrients for Healthy Cell Renewal
To ensure that your body builds strong, healthy cells, focus on the following nutrients:
1. Protein – The Building Blocks of Life
Proteins are essential for cellular repair and growth. They provide amino acids that are needed to build everything from muscle fibers to enzymes.
Best sources:
- Lean meats (chicken, turkey, beef)
- Fish and seafood
- Eggs
- Dairy products (Greek yogurt, cheese)
- Plant-based sources (beans, lentils, tofu, nuts)
2. Healthy Fats – Supporting Cell Membranes
Your cells are surrounded by protective membranes made of fat. Consuming the right types of fat keeps these membranes strong and flexible.
Best sources:
- Avocados
- Olive oil
- Nuts and seeds
- Fatty fish (salmon, mackerel, sardines)
- Coconut oil
3. Vitamins and Minerals – Fuel for Regeneration
Your body needs a variety of micronutrients to fuel cell regeneration.

Key vitamins and minerals:
- Vitamin C: Boosts collagen production for healthy skin and tissue repair. (Sources: citrus fruits, bell peppers, strawberries)
- Vitamin D: Supports bone renewal and immune function. (Sources: sunlight, fatty fish, fortified dairy)
- Iron: Helps form new red blood cells. (Sources: red meat, spinach, legumes)
- Zinc: Essential for wound healing and cell growth. (Sources: nuts, seeds, shellfish)
4. Antioxidants – Protecting Your Cells
Antioxidants help neutralize harmful free radicals that can damage your cells. They support healthy aging and reduce the risk of chronic diseases.
Best sources:
- Dark leafy greens (spinach, kale)
- Berries (blueberries, raspberries, blackberries)
- Dark chocolate (at least 70% cocoa)
- Green tea
- Turmeric
How Poor Diet Choices Affect Your Body’s Regeneration
If your diet is filled with processed foods, sugary drinks, and unhealthy fats, your body struggles to build strong, healthy cells. Here’s how bad nutrition can negatively impact cellular regeneration:
- Fast Food and Junk Food: Processed foods are often low in essential nutrients and high in trans fats, which can damage cell membranes.
- Sugar Overload: Excess sugar leads to inflammation and premature aging of cells. It can also accelerate the breakdown of collagen, leading to wrinkles and joint pain.
- Lack of Hydration: Your cells need water to function properly. Dehydration slows down cell turnover and can lead to fatigue, brain fog, and dry skin.
- Deficiency in Key Nutrients: If your body lacks essential vitamins and minerals, your cell renewal process slows down, leading to poor immunity, brittle nails, and slow wound healing.

Lifestyle Habits That Boost Cellular Regeneration
Besides eating a nutrient-rich diet, certain lifestyle habits can enhance your body’s natural ability to regenerate.
1. Prioritize Sleep
Your body repairs itself during sleep. Growth hormone, which plays a key role in cell renewal, is released at night. Aim for 7-9 hours of quality sleep to maximize cellular regeneration.
2. Exercise Regularly
Physical activity increases blood flow, delivering oxygen and nutrients to your cells. Strength training, cardio, and yoga all contribute to improved cell health.
3. Reduce Stress
Chronic stress leads to increased inflammation, which can damage cells over time. Practicing meditation, deep breathing, and mindfulness can help protect your body from premature aging.
4. Stay Hydrated
Water is essential for every cell function. It helps flush out toxins, transport nutrients, and maintain proper hydration levels. Drink at least 8 glasses of water daily.
5. Avoid Smoking and Excessive Alcohol
Both smoking and excessive alcohol consumption accelerate cell damage and impair regeneration. Cutting back or eliminating these habits will dramatically improve your overall health.

Conclusion: You Truly Are What You Eat
Every 35 days, your body replaces its skin cells. Over time, your entire body is constantly renewing itself. What you eat provides the raw materials for this process—so make sure you’re feeding your body the nutrients it needs to thrive.
By choosing a diet rich in protein, healthy fats, vitamins, and antioxidants, and maintaining healthy lifestyle habits, you can optimize your body’s natural regeneration process. Your future self will thank you!
Now, take a moment to think—if your body is rebuilding itself right now, what do you want it to be made of?
Harrison Ford was married twice before he met and fell in love at 67 with his third wife, actress Calista Flockhart.

Harrison Ford fell in love at 67 with a much younger woman after two failed marriages, and he even adopted her son. The actor felt like a little boy again and gushed over his wife, with whom he lives a quiet life on a farm where they enjoyed spending time in the woods.
Harrison Ford was married twice before he met and fell in love at age 67 with his third wife, actress Calista Flockhart. In 1964, the actor tied the knot with his first wife, Mary Marquardt.
Harrison began working as a carpenter to support their two sons because he wasn’t a famous actor. In 1977, he was featured in “Star Wars” and found fame, but his marriage wasn’t equipped to handle the Hollywood lifestyle.
Carrie Fisher, his “Star Wars” co-star, confessed years later that they had an “intense” illegal substance-fueled affair while he was married. Long after his marriage to Marquardt ended in 1979, Harrison went into union with Melissa Mathison in 1983.However, before tying the knot, the duo failed to sign a prenuptial agreement. The “E.T.” screenwriter and the actor welcomed a son and a daughter, but their relationship was also not meant to last.
The “Raiders of the Lost Ark” star paid a whopping $85 million when he and his second wife divorced in 2004. Their separation was described as amicable, but it was rumored that Harrison had been adulterous.
In 2003, Harrison, then 60, who was usually reserved about his personal life, admitted, “I’m in love” when speaking about his relationship with Calista, then 38. He said romantic love was one of the most fulfilling and exciting kinds of love, adding:
“I think there is a potential for it at any stage of your life.”
The star revealed he wasn’t surprised that he could fall in love and did. At the time, the “Ally McBeal” actress and Harrison had been dating since January 2002 when they met at the Golden Globe Awards.
However, until that interview, the actor had been reluctant to open up about his relationship with Calista. The “Indiana Jones” star was so serious about the actress that he proposed on Valentine’s Day in 2009!

Harrison’s proposal to make Calista his third wife happened while they were on vacation. The couple didn’t waste much time before making their relationship official and married in Santa Fe, Mexico, in June 2010.
Before the actress began dating Harrison, she’d become a single parent by adopting her son, Liam, in 2001. However, after marrying the actor, he formally adopted Calista’s son, adding him to his other four children from his previous marriages.
In 2008, the star, then 65, confessed that being a father again to a young child “made me just a bit less self-centered.” He revealed how Calista had brought a child back into his home.
At the time, Harrison shared how his youngest child was 17, other than Liam. He reveled in having the “wonderful opportunity” to be a part of a child’s upbringing, which he described as “always an endless springtime.”
The star gushed about seeing how the growing, blossoming, and nurturing were paying off. The People magazine’s 1998 Sexiest Man, Alive’s other two older sons with Marquard were Benjamin, then 40, and Willard, 39.
With Mathison, Harrison had a son Malcolm, then 21, and a daughter Georgia, then 17. When speaking about the sort of mother Calista was, the actor said she was the best in the world!

He explained that she was a mother by choice and took on a great responsibility when she adopted her son as a single parent. The actor noted how his wife had devoted herself to Liam and was doing a fantastic job raising him.
Harrison shared how he was pleased to be helping with the job of parenthood. However, he noted that he was “naturally” different with Liam compared to his other children because now he was a little more mature.
Calista and her husband were completely in love, and this time around, the marriage might not end in divorce. The couple was so in tune that they had activities they did together, and the actress once had the role of caretaker for Harrison.
Finding True Love and Companionship at 67
When Harrison met Calista in 2002, he wasn’t looking for love. The former explained that there were times when he felt lonely, but he didn’t want to live his life mitigating “against loneliness.”
The actress, who had allegedly dated many celebrities in her past, including comedian Garry Shandling and actor Ben Stiller, had never had an interest in Harrison before. She once confessed:
“I remember loving him in ‘Mosquito Coast,’ but I didn’t really think about him.”

On the other hand, Harrison also seemingly didn’t have sights on the actress but recalled watching “Ally McBeal” once in a while before meeting Calista. However, now that they were together, she wasn’t allowing him to watch the comedy series because she didn’t like seeing herself.
In 2003, the couple opened up about the age gap between them. The actress admitted that it didn’t “faze” her, and she sometimes would forget that Harrison was 22 years older than her!
Calista said the age difference didn’t factor into their relationship in any way. Instead, the star liked how the actor looked first thing in the morning; she said he wasn’t handsome but more cute and looked like a “little boy.”
There were also conflicting stories about how the couple met. Some reports claimed that the actress threw a drink over Harrison, but he explained that she didn’t intentionally spill her glass of wine on him.
She said they conversed for around 20 minutes before the wine spilled, and Harrison was the one who did the spilling! In 2015, the couple discussed the mutual activity that they enjoyed together.
Years before, in 2003, Harrison had shared with the public that Calista loved flying. He said it thrilled him because it was important to him, as it was more fun when done with someone who enjoyed it.
The actor shared how the actress liked the process, what she saw from the air, and seeing him happy. He speculated that she enjoyed it most because she loved seeing him do something he loved.
Calista revealed that she had complete confidence in his piloting abilities. She confessed to having been a bit nervous about flying, but surprisingly, when she went to Santa Barbara with her husband for the first time, she didn’t feel any nervousness; instead, the star loved it!

The actress believed she loved the sport because she trusted her husband, and she revealed they would take Liam flying all the time, and he loved it too! Besides flying, Calista and Harrison tried to be a giving family.
On November 21, 2007, the couple and their son, then 6 1/2, went together to assist in feeding the homeless in Los Angeles. The couple was photographed wearing Los Angeles Mission aprons as they dished up food.
The actors even wore gloves as they taught Liam about the blessing of giving back to the less fortunate. Then in 2015, tragedy struck the family when, at age 72, Calista’s husband was involved in a plane crash and suffered a nasty laceration on his face.
The actor had to be rushed to a local hospital where his wife, then 50, son Benjamin, and daughter Georgia rushed to be by his side. The actress stayed with her husband at the E.R. section of the hospital until late at night after his vintage plane crashed.
The following day, a Friday, she was photographed driving away from the hospital. Calista allegedly looked tired and was seen holding a tissue, but later that day, she returned to the hospital to be by his bedside.
Sources said the actress “looked concerned” when she arrived shortly after her husband. The following morning she allegedly drove Liam to school before returning to the hospital and remaining there to take care of Harrison.

An insider described the couple and their family as normal, “super loving,” and down to Earth. The couple, who waited for over eight years before getting married, whose shared love for flying was mentioned by the source, before adding this about Harrison’s hospital stay:
“This whole thing must be terrifying.”
Ultimately, Harrison recovered from his injuries and returned to his family. The actor, his wife, and his adopted son now live on a ranch where they keep busy with various activities.
Calista and Harrison’s Quiet Life on a Farm
In August 2022, it was reported that Harrison and his family live on a Jackson Hole, Wyoming ranch. “The Fugitive” star’s home boasted 800 acres of land and was located along Snake Rover.
It was revealed that year that Harrison said he had lived there for 35 years. He even confessed that when he was in Wyoming, he had the leisure of just walking out of the door and continuing.
The farm was described as a “personal sanctuary” for the actor, his wife, and Liam. In 2020, it was revealed that Harrison split his time between his Wyoming ranch and Los Angeles home, which he shared with the “Brothers & Sisters” actress.

Besides living quietly on their properties, Calista’s husband kept busy with his career. That year he was back on the big screen starring in “The Call of the Wild,” an adaptation of the classic Jack London novel.
According to reports, the actor also used to own a home in Brentwood, California, but in 2012 he put it up for sale for $8,295,000. The property had been his home for almost 30 years when he sold it.
Harrison bought the Gerard Colcord-designed country Colonial home in June 1983 for a mere $1 million. The house was initially built in 1951, and its 7,164-square-foot space boasts four bedrooms, an additional poolside, a one-bedroom guesthouse, and two separate guest/staff suites.
He put it on the market after buying another mansion with his wife in Brentwood that cost $12.65 million. The property was described as their longtime primary residence in Los Angeles.
When on the ranch, Harrison spent his days balancing his time between doing a little work and a little play. He once revealed that when his chores were done, and there was nothing more pressing waiting for him, he liked flying when the weather was good.
The “Blade Runner” star admitted that he loved flying in Wyoming. However, sometimes he opted to walk in the woods, do some work, and ride his road or mountain bikes.
Calista’s husband also shared that he had chores given to him by his wife, and he was always working on fixing something on the property. He did the home maintenance, worked in his woodshop, or discussed putting in a new roof with some people.
When the “Air Force One” actor wasn’t doing all those things, he enjoyed spending quality time with his wife while raising Liam. In 2010, the star opened up a little about what he did with his adopted son.
Harrison [Ford] shared some things he’d learned over the years to help make his marriage last.
He revealed that he did whatever his wife and son wanted to do on weekends. Sometimes on Sunday mornings, they went hiking, or motorcycle riding, or he and Liam would make a birdhouse, which took him three days!
Speaking about his son, Calista’s husband said having a then nine-year-old child was something he hadn’t expected. The star grinned when he shared that it was also a joyful experience.
He recalled Liam was around six or eight months old when he met him and his mother; they’ve been together since! In 2020, the couple celebrated their tenth wedding anniversary.
Harrison shared some things he’d learned over the years to help make his marriage last. The “Supergirl” actress’ husband joked that it was best not to talk and nod your head.
He also hilariously admitted that he had no idea where his dry humor came from. The actor said he’d never thought about his humorous side and noted, “I see funny, I think.”
