Why Nuts Aren't Part of the 5 A Day
The most frequent reason nuts are not included in the '5 a day' fruit and vegetable target is their unique nutritional composition. Nuts are valued for their healthy fats, protein, and fiber. Fruits and vegetables are prioritized because of their high water content and low energy density. Most dietary guidelines place nuts in a different food group, often with meat, fish, and other protein sources.
When the '5 a day' campaign was first developed, nuts were seen as a high-fat snack, which is why they were not included. Although this perception has changed, the official guidelines have remained consistent. Due to their high energy density, nuts would contribute a disproportionate number of calories compared to fruit or vegetables. Portion control is important with nuts, which makes them unsuitable for the volume-based metric of the '5 a day' target.
The Extensive Health Benefits of Nuts
Even though they are excluded from the '5 a day' count, nuts are nutrient-rich and offer many health benefits. Regular nut consumption can have a significant positive impact, especially on heart health.
Heart Health and Cholesterol
Studies show a link between regular nut consumption and a reduced risk of coronary heart disease. Their rich profile of monounsaturated and polyunsaturated fats, fiber, and plant sterols helps to lower unhealthy LDL ('bad') cholesterol and triglycerides. These healthy fats also contribute to better overall blood vessel health and may help reduce inflammation.
Antioxidant and Anti-inflammatory Properties
Nuts contain antioxidants, such as polyphenols, which fight oxidative stress by neutralizing free radicals that can damage cells. This has been linked to promoting healthy aging and reducing chronic, low-grade inflammation, which is a risk factor for many diseases.
Weight Management
Nuts may aid in weight loss. This is due to the fat in nuts not being fully absorbed by the body, their high fiber and protein content increasing feelings of fullness, and they can help reduce overall calorie intake from other sources.
How to Include Nuts in a Healthy Diet
A moderate portion of nuts should be a regular part of your diet. A recommended portion is about 30 grams, or a small handful. Here are some ways to enjoy them:
Healthy Ways to Eat Nuts
- As a snack: A small handful of plain, unsalted nuts is a great way to curb hunger between meals.
- Topping for dishes: Sprinkle chopped nuts over yogurt, porridge, or salads for added crunch and nutrients.
- Nut butter: Choose natural, unsalted nut butters without added sugar. A serving is typically two tablespoons.
- Ingredient in cooking: Add nuts to stir-fries, curries, or homemade trail mix to boost flavor and nutritional value.
Nuts vs. Seeds: A Nutritional Comparison
Seeds are also discussed alongside nuts for their similar nutritional profiles, and like nuts, they do not count towards the '5 a day' target. However, both are valuable for a diverse and healthy diet. The concept of aiming for 30 different plant foods a week, which includes nuts, seeds, whole grains, and legumes, is gaining traction as a way to support gut health. This broader perspective acknowledges the importance of these foods beyond the '5 a day' framework.
Nut and Seed Nutritional Comparison
| Food (per 30g) | Key Healthy Fats | Fiber (g) | Protein (g) | Notable Micronutrients | 
|---|---|---|---|---|
| Almonds | Monounsaturated | 3.5 | 5 | Vitamin E, Magnesium, Calcium | 
| Walnuts | Polyunsaturated (Omega-3) | 2.9 | 4.3 | Omega-3 fatty acids, Antioxidants | 
| Pistachios | Monounsaturated | 2.9 | 6 | Vitamin B6, Potassium, Lutein | 
| Chia Seeds | Polyunsaturated (Omega-3) | 10.6 | 5 | Omega-3s, Calcium, Iron, Antioxidants | 
| Pumpkin Seeds | Polyunsaturated | 1.8 | 7.7 | Zinc, Magnesium, Iron | 
Conclusion: Nuts and a Balanced Diet
The answer to whether nuts count towards your '5 a day' is no, based on standard dietary guidelines like those from the NHS. This is because they are classified as a healthy source of fats and protein, not a fruit or vegetable. However, this classification should not diminish their importance in a balanced diet. A small, regular portion of unsalted nuts provides a wealth of benefits, from supporting heart health and weight management to delivering essential vitamins and minerals. Rather than seeing their exclusion as a negative, view nuts as a separate, but equally crucial, part of a nutritious and varied diet.
