We are all faced with the same decision every day. What to eat. We often consider the healthiness of food when making a purchase, along with other factors such as price, availability, and personal preference.
How can we be sure that we are getting all the nutrients our bodies need when we look at our diets in their entirety?
Researchers agree that we should eat a variety of foods. One way to achieve this is to eat all the colors of the rainbow. Is color the best way to get all the nutrients you need?
The proof may be in the Mediterranean diet, which contains a lot of fruit, vegetables, and healthy fats such as extra virgin olive oil and is frequent.
He adds that the colors are not different from other diets based on vegetables, like the vegetarian diet. The Mediterranean diet is also healthy for other reasons. Sofi says that Mediterraneans traditionally boil their vegetables rather than fry them, which preserves the nutrients.
The abundance of fruits and vegetables in the diet cannot be ignored. According to Deanna Minich of the University of Western Portland, Oregon, a functional nutritionist and adjunct University of Western States faculty, a diet high in fruits and vegetables is beneficial for our hearts and brains.
You may be able to reduce your risk of not getting all the nutrients you need by eating a variety of colors.
Minich says that if we are missing one of the colors of the rainbow, we could be missing out on a food’s function.
Plant foods are rich in phytonutrients such as carotenoids, flavonoids, and flavonoids that have anti-inflammatory properties. Different colors of plants have other benefits.
Anthocyanin is a plant pigment that gives blue and purple foods their color. It has been shown to reduce the risk of heart disease and type 2 diabetes. Flavones give yellow foods their color. They may lower the risk of heart disease.
Minich explains that certain plant pigments can travel to specific parts of the human body and settle there. “For instance, lutein can be found in yellow and green food and travels to macula, the retinal tissue at the back, where it could help reduce macular degeneration.”
Some studies show flavonoids can improve brain health by blocking the neurotoxicity of the brain. This is linked with Alzheimer’s.
Tian-shin Yeh is a research fellow at Harvard TH Chan School of Public Health. She studied the diets of 50,000 individuals over 20 years.
Yeh says that while there is no cure for cognitive impairment and dementia in older age, eating foods rich in flavonoids can reduce the risk. The participants who experienced the greatest benefits were those who had been consistently eating a diet rich in flavonoids for at least 20 years.
Yeh says it’s never too early to add these foods to your diet and reap the benefits of flavonoids.
Yeh says that eating a varied diet can help to avoid the adverse effects of eating too many of a particular food.
“Food is complex.” She says that, for example, studies have shown orange juice consumption is associated with lower cognitive decline, but too much is linked to type 2 diabetes. This is due to its sugar content and not flavonoids.
Victoria Taylor, senior dietitian with the British Heart Foundation, explains that eating a rainbow-colored diet can be complicated.
She says that it could be difficult to have every color every day. You could get yourself into knots.
She says we also need to consume other food groups in order to get the macronutrients that we need.
Minich also considers white food as part of the rainbow diet, including tofu, which contains numerous different isoflavones that have been associated with a lower risk of heart disease and some cancers, as well as cognitive decline. She considers white foods as part of the Rainbow Diet, such as tofu. Tofu contains many different isoflavones that have been linked with a reduced risk of heart disease, some cancers, and cognitive decline.
Eating more fruits and vegetables could be attributed to eating a range of colors. In one study, encouraging people to eat colorful meals led them to consume more healthy foods.
If you eat the same fruit every day, you will become satisfied. But if you eat a variety of fruits and vegetables with different colors, you are likely to linger over your meal. This is according to Rochelle Embling, a PhD student from Swansea University who was not involved in the research.
Embling explains that “this effect is specific to food eaten. So after a meal dessert remains appealing because it has different sensory qualities.”
A more colorful diet can also increase your risk of eating too much unhealthy food. Embling found that people are more likely to consume more pizza with a variety of colorful toppings. She recommends eating a variety of colors when it comes to fruit and vegetables but choosing fewer colors for indulgent food. It is also important to note that foods with artificial colors, like cake and sweets, do not count towards a healthy diet.
Researchers say that there are other ways to obtain a variety of phytonutrients and nutrients in your diet besides color. For example, paying attention to the taste. Researchers found that participants consuming bitter or strong-tasting vegetables for 12 weeks had lower blood sugar and blood pressure at the end of the study. This was due to the fiber and phytonutrients in these vegetables.
According to the study: “Root veggies and cabbages contain antioxidants like flavonoids and carotenoids. Combining them in whole foods can provide enhanced health-promoting benefits.”
They may also be healthier when combined.
Minich agrees that bitter foods such as celeriac, rocket, kale, and green tea are important to our diet. She also stresses the health benefits of the compounds in these foods reacting together.
Yeh suggests that you also consider the parts of plants that you are eating.
“Turnips have a similar nutritional value to swedes because they both are the roots; however, the nutritional value of cabbage and swede is not as similar because the one is a leaf and the other is the root.”
Yeh admits that “considering the colors may be the best way to guide consumers.”
