You are what you eat, and to science it is true. People live longer based on what they choose to eat. With such a thought, Canadians took on to a UK-based challenge of eating vegan for a month. The challenge is called Veganuary (Vegan + January). For many, it is not a hidden fact that eating less meat and more plants is good for our health and it can cut food-related emissions, which make up to a third of the greenhouse causing climate change. However, going vegan isn't really a smooth change, rather a big step. It means to revamp our entire diet.

The good news is, that there have been researches that prove that even relatively small substitutions of red meat with plant-based proteins like tofu, lentils and beans can add months, sometimes years to our expected lifespan. It can also make a noticeable dent in our carbon footprint.

The Rise Of Vegetarianism

As per 2018, only 7.1% of Canadians were vegetarian and 2.3% were vegan. Olivia Auclair, a research fellow at the University of Oxford, who researched on Canadian's eating habits told CBC that Canadians get 65% of their protein from animal sources. Only 5% of the protein comes from the high-protein plant-based sources. Some of these are also included in Canada's Food Guide.

It is true that eating habits, along with shopping habits are hard to change, this is why Auclair's research tried to bring people more in line with the food guide. The Canada Food Guide recommends lots of fruits, vegetables and whole grain, along with protein from both animal and plant sources.

What is the study all about?

Her research was published last year in the journal Nature Food, titled Partial substitutions of animal with plant protein foods in Canadian diets have synergies and trade-offs among nutrition, health and climate outcomes, found that replacing half their red and processed meat would increase people's life expectancy an average of nine months, while cutting their diet-related carbon footprint by 25%.

For her research, she analyzed what 13,600 Canadians ate based on the Statistics Canada data from "food diaries" recorded by them in 2015. After that, she modelled what could happen if the same people substituted 25 to 50% of the red and processed meat they had been consuming with plant-based proteins. However, they did not change their poultry, fish or seafood intake.

The results were great, as mentioned above. In fact, there was more. The health benefits were double for men compared to women!

Men gained one full year of increased life expectancy, on average. This is also because men eat more red and processed meats and the climate benefits were also higher for men cutting down on the meat.

Plant-based Diets

In 2019, an international group of scientist recommended a planetary health diet, a plant-based diet rich in fruits, vegetables, legumes, nuts and whole grain, with small amounts of meat, dairy and fish, similar to what is recommended by the Canada Food Guide. The reason for such a recommendation was also to prevent 11 million deaths per year from processed meats and help keep greenhouse gas emission from food.

Another US study that looked at 200,000 US healthcare workers found that eating a plant-based diet could reduce a person's risk of dying by 30% from heart diseases, cancers, and respiratory diseases. Another 2021 Swedish study found a similar benefit, where it saw a 25% drop in mortality for those who adhere to a plant-based diets.

Collagen is essential for maintaining firm skin, prevent premature aging and regulates cell proliferation. While it is usually found in animal sources, many fruits and super foods acts rich sources.

Tiny but mighty, eating blueberries not only gives you a sweet taste but also can be extremely beneficial for your entire body.

Extremely rich in antioxidants called anthocyanins, they help with slowing down brain aging. Along with this, the fruit also helps regulates blood pressure and cholesterol levels, overall improving cardiovascular health.

Although they might sound beneficial, they are pricey and inaccessible to a majority of the public.

However, experts have now revealed that guava can provide the body with more benefits than blueberries at half the price.

Why Is Guava Better Than Blueberries?Guavas are living proof that appearances are deceptive. Packed with nearly five times more Vitamin C (about 228mg) and loaded with digestive fibers, this winter fruit is perfectly suited for everyday snacking.

According to Healthline, a single guava can fulfill 12 percent of your recommended daily intake of fiber. A 2025 overview by PubMed also shows that guava leaves have been researched for managing blood sugar levels.

Guavas contain soluble fibers which slow down the digestion and absorption of sugars, preventing sudden spikes in glucose levels. Previous research also shows that regular consumption can help improve insulin sensitivity and lipid profiles, benefiting metabolic health.

With significantly higher Vitamin C content than blueberries, this fruit supports collagen production and gives you brighter skin and protection against premature aging.

Which Other Fruits Are Rich in Antioxidants?

While cranberries support urinary tract health by preventing bacterial adhesion and reducing inflammation, strawberries are rich in Vitamin C and folate and help with blood sugar regulation which can help stabilize glucose levels.

While blueberries have been linked to improving skin texture, goji berries are far rich in flavonoids that can neutralize free radicals, boost collagen and protect against UV damage.

Blackberries and raspberries are excellent sources that reduce oxidative stress and inflammation.

Experts recommend incorporating a mix of these fruits in your diet to help repair your DNA, reduce inflammation and prevent chronic conditions.

If you drink 14 drinks per week, the American Cancer Society's peer-reviewed journal Cancer, noted that you have a 25% higher risk of developing colorectal cancer. This also means that you have a 95% higher risk of developing rectal cancer as compared to those who drink an average of one drink per week.

Moderate alcohol intake is measured as seven or less drinks per week, which is associated with a lower risk. However, experts have time and again stressed that there is no safe limit of drinking.

"While the data on former drinkers were sparse, we were encouraged to see that their risk may return to that of the light drinkers,” co–senior author Erikka Loftfield of the National Institutes of Health's National Cancer Institute said in a news release.

What the Study Found

The findings come from an analysis of U.S. adults who took part in the National Cancer Institute’s Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Researchers tracked 88,092 participants over a 20 year period and identified 1,679 cases of colorectal cancer during that time.

The data showed a clear pattern. Higher lifetime alcohol consumption was linked to a higher risk of colorectal cancer, with the strongest association seen for rectal cancer. However, the study also offered encouraging news. People who stopped drinking saw their risk decline, highlighting that lifestyle changes can still make a difference later in life.

Colorectal Cancer Is Rising in Younger Adults

These findings come at a time of growing concern about colorectal cancer rates, especially among younger people. Earlier this month, the American Cancer Society reported that colorectal cancer has become the leading cause of cancer-related deaths among people under 50 in the United States.

Dr. Ahmedin Jemal, senior author of the report and senior vice president of surveillance, prevention and health services research at the American Cancer Society, said the trend is alarming. He noted that the speed at which colorectal cancer rates have risen among younger adults means it can no longer be considered a disease that only affects older people.

Changing Guidance on Alcohol Consumption

Federal health guidance around alcohol has also shifted. Instead of specifying how many drinks are considered safe, the latest dietary guidelines advise Americans to drink less overall. People with certain health conditions are encouraged to avoid alcohol entirely.

Christopher Kahler, director of the Center for Alcohol and Addiction Studies at Brown University, has previously explained that no amount of drinking is completely risk-free. According to him, health risks increase with higher consumption, which is why current guidelines focus on reducing intake rather than defining a safe threshold.

What This Means for Individuals

Taken together, the research reinforces a simple message. Heavy drinking raises cancer risk, drinking less is better for health, and stopping alcohol use can help lower the chances of developing colorectal cancer. With rates rising in younger adults, experts say awareness and prevention efforts are more important than ever.
