So far, we have covered many different kinds of diets, including the Harvard Diet, the Paleo Diet, the Vestibular Migraine Diet, the Portfolio Diet and the F-Factor Diet. Another one that is on the list and something that people turn to for weight loss or help with digestive concerns is the Whole30 diet.
It is a strict 30-day elimination diet that cuts out alcohol, sugar, grains, legumes, dairy, and additives from your diet, straight for 30 days. It is advertised as a total lifestyle change, rather than a simple diet.
As the name suggests, it also focuses on a 30-day-long diet that promises a variety of health and emotional benefits. It was first developed in 2009 by two certified sports nutritionists who promoted it as a way to reset your metabolism and reshape your relationship with foods.
The Whole30 program is built on the idea that certain foods—like sugar, grains, legumes, alcohol, and dairy—may negatively affect your health and overall fitness. By removing these items from your diet, the program aims to help your body recover, reset, and achieve long-term health. Many people adopt this plan to lose weight, identify food intolerances, or improve their relationship with food.
The Whole30 diet is a strict, month-long elimination program that encourages eating minimally processed, whole foods while avoiding specific items believed to cause inflammation or disrupt hormones. This approach emphasizes a reset period where no deviations from the rules are allowed. The program claims to improve physical and emotional well-being by changing how you view food.
Unlike other diets, the Whole30 does not require calorie counting, portion control, or daily weigh-ins. Instead, weight tracking is only allowed on days 1 and 30 to keep the focus on overall health rather than just the scale.
For 30 days, participants completely avoid certain foods and focus on approved options. After this elimination phase, foods are gradually reintroduced to assess how they impact the body. This reintroduction phase helps identify triggers for bloating, skin issues, or other negative symptoms.
Adherence is key; any slip-ups mean starting the program over. The Whole30 encourages mindful eating and aims to reshape unhealthy food habits.
Despite these claims, there is no scientific evidence directly supporting the benefits of the Whole30 diet.
Even creating “healthy” versions of indulgent foods like paleo pancakes or cauliflower pizza is discouraged.
After completing the 30-day elimination period, the reintroduction phase begins. Foods are added back one group at a time, allowing participants to observe how their body reacts. For example, dairy might be reintroduced on day 1, followed by three days of Whole30 eating. This process helps pinpoint food sensitivities and identify which items to avoid in the future.

Black or forbidden rice, especially from Manipur, Assam and Meghalaya, has long been PM Narendra Modi's favorite superfood and experts say it has even more antioxidants than blueberries!
Registered dietitian Beth Czerwony, RD, noted: "Black rice has been slow to cross over to places outside of Asia, but we are finally starting to understand its benefits as a healthy, appetizing and beautiful food."
Belonging to the species Oryza sativa, the rice refers to a type of heirloom rice that is used in traditional Chinese medicine and was once reserved only for the wealthy and powerful, which is why it's known as 'forbidden'.
Black rice may be long-grain, medium or short-grain. Grown on a small scale, this rice is not as common as white, brown and red rice and is primarily grown in India's Northeastern states, as well as West Bengal, Odisha and Jharkhand.
Here are some of its health benefits:
Research shows that black rice contains high amounts of lutein and zeaxanthin, two types of carotenoids that work as antioxidants to help protect your eyes from potentially damaging free radicals.
In particular, lutein and zeaxanthin have been shown to help protect the retina by filtering out harmful blue light waves, which are transmitted from all electronic devices as well as LED lamps. While it helps with alertness and mood during the day, excessive blue light exposure at night can suppress melatonin and disrupt sleep-wake cycles.
Previous research also suggests that black rice's high antioxidants may play an important role in protecting against age-related macular degeneration (AMD), which is the leading cause of blindness worldwide. It may also decrease the risk of cataracts and diabetic retinopathy (a complication of diabetes that affects the eyes).
Black rice is especially beneficial for those suffering from Type 2 diabetes as antioxidants and phytochemicals can improve your body’s sensitivity to insulin. This helps the body to better use glucose, slows the rate at which the body absorbs sugar and lowers overall sugar levels in your blood.
Black rice stands out among rice varieties due to its high protein content. In comparison to brown rice, which contains 7 grams of protein per 100 grams, black rice offers 9 grams. It is also a valuable source of iron, a mineral crucial for oxygen transport in the body.
A quarter cup (45 grams) of uncooked black rice provides:
Calories: 160
Fat: 1.5 grams
Protein: 4 grams
Carbohydrates: 34 grams
Fiber: 1 gram
Iron: 6% of the Daily Value (DV)
High levels of oxidative stress have previously has been associated with an increased risk of several chronic conditions, including heart disease, Alzheimer’s, and certain forms of cancer.
While research on black rice and heart health is ongoing, its high flavonoid has been linked to a lower risk of cardiovascular disease.
Certain studies suggest that anthocyanins can improve cholesterol levels by increasing HDL (good) cholesterol and reducing LDL (bad) cholesterol. While further research is needed, early findings suggest black rice may help reduce plaque buildup in arteries, which can help prevent atherosclerosis and reduce the risk of heart attack.

Bread is a daily food for many households. Although it can be part of a balanced diet, not all breads support health in the same way, especially when it comes to blood pressure.
Sprouted whole grain bread emerged as the top choice for blood pressure support, according to dietitians, as per Healthline. Its advantage lies in its rich nutrient profile, particularly its fiber content and key minerals that play a role in blood pressure control.
Sprouted whole-grain bread is made using whole, intact grains. “The fiber present in these grains is linked to lower blood pressure, likely because it supports healthier blood vessels, helps regulate appetite, and aids in maintaining a healthy weight,” said Alexander LeRitz, MSc, RDN, CDN, CNSC, CPT, a registered dietitian at JM Nutrition, in an interview with Health.
Research shows that boosting fiber intake can be an effective way to bring down blood pressure. Studies suggest that women with high blood pressure may benefit from consuming around 28 grams of fiber daily, while men may need closer to 38 grams.
“As a general guideline, aim for bread that provides at least 3 to 5 grams of fiber per slice,” Vickie Klimantiris, RD, LDN, told Health.
Sprouted whole-grain bread also contains higher amounts of minerals that help regulate blood pressure, particularly magnesium, compared to bread made with refined white flour. For instance, two slices of Ezekiel Sprouted Whole Grain Bread provide about 12% of the Daily Value (DV) for magnesium, while the same serving of white bread offers only about 3%.
In addition, sprouted whole-grain breads such as Ezekiel bread tend to be much lower in sodium than white bread. Two slices of Ezekiel bread contain roughly 150 milligrams of sodium, compared to 268 milligrams in an equivalent serving of white bread.
“Sprouted whole grain bread also has a lower glycemic effect than white bread, so it doesn’t cause sharp spikes in blood sugar after meals,” said Rachael Ajmera, MS, RD, a dietitian, writer, and founder of Nutrimental, speaking to Health.
Here is the nutritional profile for one slice of bread:
Although sprouted whole grain bread ranked highest, dietitians also highlight sourdough as a blood pressure-friendly choice.
“I often recommend sourdough for people with high blood pressure because the fermentation process creates peptides that may help lower blood pressure by allowing blood vessels to relax,” Klimantiris explained.
For added benefits, it’s best to choose sourdough made with whole-grain flour. Whole-grain versions provide more fiber and minerals that support healthy blood pressure, including magnesium, compared to sourdough made with refined flour.
The best bread for blood pressure is one that delivers higher amounts of nutrients known to support healthy blood pressure levels, especially fiber and magnesium.
When choosing a bread that supports blood pressure health, keep the following in mind:
To support better blood pressure control, pair bread with nutrient-dense toppings such as avocado, hummus, low-sodium turkey, nut butters, or a variety of vegetables to build filling, heart-healthy meals.

A vitamin found in everyday foods may be quietly influencing how often people go to the bathroom. A large new study suggests that vitamin B1, also called thiamine, could play a role in gut movement, the process that pushes food through the digestive system.
Gut motility is more important than many people realize. When it slows down, constipation can become a problem. When it speeds up too much, people may find themselves rushing to the toilet more often than usual. Researchers wanted to understand what controls this pace and their findings pointed to an unexpected nutrient.
An international team of researchers analyzed genetic and health data from more than 268,000 people of European and East Asian ancestry. Participants were asked how frequently they had bowel movements, which researchers used as a practical indicator of gut motility.
By examining millions of genetic markers, the team identified 21 genetic regions linked to how often people passed stools. Some of these were already known to play a role in digestion, while others had never before been connected to gut function.
Using genetics allowed the researchers to map the biological systems that influence how fast the gut works. Many expected pathways appeared, including those related to nerve signaling and bile acid metabolism. But one result stood out clearly.
The strongest surprise came from genes involved in vitamin B1 metabolism. Two specific genes that help transport and regulate thiamine in the body showed a strong link to stool frequency.
Vitamin B1 is essential for energy production and nerve health. This includes the nerves and muscles that coordinate movement in the intestines. These rhythmic contractions are what push food through the digestive tract, making thiamine a plausible player in gut function.
To see whether this genetic connection translated into everyday habits, researchers analyzed dietary data from nearly 100,000 participants in the UK Biobank.
The data showed that people who consumed higher amounts of vitamin B1 tended to have more frequent bowel movements. This suggested that diet could influence gut movement, at least to some extent.
However, the effect was not seen equally in everyone. The relationship varied depending on a person’s genetic makeup. This suggests that some people may process or respond to vitamin B1 differently than others.
In simple terms, vitamin B1 may help regulate how fast the gut moves, but genes help decide how noticeable that effect is.
The researchers stressed that the findings have limits. Stool frequency alone does not capture the full picture of digestive health. It does not reflect stool consistency, abdominal pain, bloating, or discomfort, all of which are important symptoms.
The study also relied on self reported dietary information, which can be inaccurate. In addition, genetic associations do not prove direct cause and effect.
Crucially, the findings do not mean that taking vitamin B1 supplements will fix constipation or digestive issues. The exact biological pathway is still unclear.
This research adds to growing evidence that digestion is shaped by both diet and genetics. While vitamin B1 appears to be involved in gut movement, digestive problems are complex and highly individual.
People experiencing ongoing bowel issues should consult a doctor rather than turning to supplements on their own. What helps one person may not help another.
For now, the study opens an interesting door into how everyday nutrients may influence basic digestive functions.
