Lean proteins such as chicken, legumes, and oily fish can help balance blood sugar
Lean proteins are an essential component of a healthy diet, and they can play a crucial role in managing blood sugar levels. While carbohydrates are the body's primary source of fuel, proteins help control the absorption of sugars into the bloodstream, preventing spikes in glucose levels. This is especially important for individuals with diabetes or hyperglycemia, as it helps maintain stable blood sugar levels.
Lean proteins such as chicken, legumes, and oily fish are recommended for balancing blood sugar. Chicken is a versatile lean protein option that can be prepared in various ways to suit different tastes and preferences. Legumes, including beans, offer a plant-based source of lean protein and are a great choice for individuals looking for vegetarian or vegan alternatives. Oily fish, such as salmon or sardines, provide not only protein but also healthy fats, which have been shown to have beneficial effects on blood sugar regulation.
The combination of lean protein with fiber-rich carbohydrates and heart-healthy fats can be particularly effective in stabilising blood sugar. For example, a meal consisting of grilled chicken with a side of quinoa and steamed broccoli ticks all the boxes. The protein from the chicken, the fiber from the quinoa, and the healthy fats from the broccoli work together to slow down the digestion of carbohydrates, preventing a rapid rise in blood sugar levels.
It is important to note that the impact of protein on blood sugar levels may vary depending on other factors, such as insulin levels and overall diet composition. While lean proteins can help balance blood sugar, they should be consumed as part of a balanced diet that includes a variety of whole grains, vegetables, nuts, seeds, and healthy fats. Portion sizes are also crucial, and it is generally recommended to keep the protein portion equal to or larger than the carbohydrate portion to ensure blood sugar control.
In summary, lean proteins such as chicken, legumes, and oily fish are valuable tools in managing blood sugar levels. By incorporating these foods into a well-rounded diet and paying attention to portion sizes, individuals can effectively contribute to stabilising their blood sugar and overall health.

Whole grains, vegetables, nuts, and seeds are recommended for blood sugar control
A person's diet has a significant impact on their blood sugar levels. While it is not the only factor, the food we eat plays a crucial role in balancing our blood glucose levels and minimising extreme highs and lows. Eating nutritious foods with low glycemic index scores can help manage diabetes and keep blood sugar levels in check.
Non-starchy vegetables, such as leafy greens (romaine, kale, spinach), peppers, tomatoes, and onions, are also high in fibre, low in calories, and packed with nutrients. Filling half of your plate with these vegetables and eating them early in your meal can help you feel full faster and prevent overeating carbohydrates. Additionally, all nuts are a good source of protein and healthy fats, which slow down the digestive system and the release of sugar into the bloodstream. When choosing nuts, opt for no-salt or low-salt varieties, and avoid added sugars in nut butters. Seeds, such as chia, flax, pumpkin, sunflower, and sesame, are excellent alternatives, especially for individuals with nut allergies.
While all fruits contain natural sugar, berries have the lowest amount and are a good choice when paired with protein sources like Greek yoghurt, nuts, or cheese to counteract the glucose. It is important to note that while a balanced diet is crucial for controlling blood sugar, healthy lifestyle choices, such as exercise and staying hydrated, also play a positive role in maintaining stable blood sugar levels.

Refined carbohydrates and added sugars can increase blood sugar levels
Simple carbohydrates, such as those found in refined grains and added sugars, have simple chemical structures that are easily and quickly utilized for energy by the body. This often leads to a faster rise in blood sugar and insulin secretion from the pancreas, which can have negative health effects. These negative health effects include an increased risk for type 2 diabetes, heart disease, and weight gain.
To prevent spikes in blood sugar, it is recommended to consume complex carbohydrates that are low in added sugar and contain fiber. Whole grains, such as whole wheat bread, brown rice, and oats, are excellent sources of fiber. Fiber acts like an outer shell covering the carbohydrates, creating a slight delay in the flow of sugars into the bloodstream.
In addition to choosing complex carbohydrates, pairing carbohydrates with protein can also help control blood sugar levels. Proteins slow down the release of sugars into the bloodstream, allowing blood sugar to stay within a more normal range. O'Meara, an expert in diabetes management, recommends aiming for equal-sized portions of protein and carbohydrates to ensure you're getting enough protein to counteract the carbs.
Overall, a balanced diet and healthy lifestyle choices are key to controlling blood sugar levels. This includes incorporating a variety of whole grains, vegetables, nuts, seeds, lean protein sources, and healthy fats into your diet, while limiting refined carbohydrates and added sugars.

Leafy greens and non-starchy vegetables are high in fibre and low in calories
Food plays a crucial role in balancing blood glucose (blood sugar) levels. Carbohydrates, especially refined carbohydrates and sugar, can increase blood sugar levels. Therefore, people with hyperglycemia should avoid high-sugar foods and refined carbohydrates.
Filling half your plate with these vegetables, as suggested by O'Meara, can help you feel full faster and prevent overeating carbohydrates. Additionally, the low-calorie content of these vegetables allows you to consume large portions without worrying about excess weight gain. They are also composed of about 90% water, contributing to your daily fluid intake.
Including a variety of non-starchy and starchy vegetables in your diet is recommended. Starchy vegetables, such as potatoes, rice, and squash, contain higher amounts of carbohydrates and calories. However, they also provide health benefits, including resistant starch, which acts like soluble fibre and has positive effects on gut bacteria. Therefore, mindful portion sizes and cooking methods are important when consuming starchy vegetables.

Exercise, hydration, and weight management can positively impact blood sugar levels
Exercise, hydration, and weight management are key factors in maintaining healthy blood sugar levels. While diet plays a significant role in managing blood sugar, these factors can also help keep blood glucose levels in check.
Exercise
Regular exercise and physical activity can effectively lower blood glucose levels in the short term and reduce A1C levels over time. Physical activity increases insulin sensitivity, allowing your body to utilize glucose more efficiently. Additionally, exercise helps your muscles use blood sugar as energy, benefiting muscle contraction. The intensity and duration of exercise can influence the impact on blood sugar levels, and regular activity can help prevent blood glucose spikes. Checking blood glucose levels before and after exercise can help individuals understand how their body responds to different activities and adjust their workouts accordingly.
Hydration
Drinking adequate water is essential for maintaining healthy blood sugar levels. Research suggests that proper hydration is associated with lower fasting blood sugar and insulin levels. A 2021 review of observational studies found that individuals who consumed more water had a decreased risk of developing high blood sugar levels. Water helps prevent dehydration and assists the kidneys in flushing out excess sugar through urine. Staying hydrated is especially important for individuals with prediabetes or diabetes, as hyperglycemia can lead to dehydration.
Weight Management
Maintaining a healthy weight is crucial for regulating blood sugar levels. Even a modest weight loss of 5% can significantly improve blood sugar control and reduce the need for diabetes medication. Managing calorie intake and monitoring serving sizes are essential components of weight management, which positively impact blood sugar levels.
