Vegetables in the Cruciferous family
Cruciferous vegetables, which are known for their popularity, are abundant with exclusive bioactives that can have a direct and beneficial effect on your immune system. A study published in Cell, a scientific journal, revealed how those vegetables significantly influence the chemical signal responsible for activating intra-epithelial lymphocytes - an imperative category of immune cells that play an essential role in initiating defense against invaders.
The researchers further observed through studies conducted on animals as models that when deprived of cruciferous veggies from their diet, there was a drastic decline of about 70% to 80% in these safeguarding cells.
Sweet Potatoes
The bright, orangey flesh of sweet potatoes signifies the high content of antioxidants in this healthy root vegetable, remarks Sarah Schlichter, MPH, RDN, a registered dietitian. The antioxidants don't only provide general health benefits but they also help to strengthen the body's immune defenses.
A single medium-sized sweet potato gives more than 100% of your daily requirement for vitamin A—in its beta-carotene form—according to one study. Additionally, consuming sweet potatoes might be an effective way to ward off vitamin A deficiency. Besides that, you'll get nearly half (40%) of your recommended daily dose of vitamin C from these root vegetables on top of other essentials like fiber, potassium and magnesium.

Almonds
Almonds are frequently considered food that boosts the immune system, primarily due to their high vitamin E content, characteristic of tree nuts. These nutritious powerhouses supply 4 grams of dietary fiber and healthy unsaturated fats. They also offer other nutrients such as plant-based protein (6 grams), magnesium, selenium, copper, zinc, along with Vitamin E.
Almonds have the highest Vitamin E concentration among all nuts. Research supports that vitamin E contributes positively towards T-cell production – these cells play a crucial role in our immune system by combating pathogens. Additionally,other research evidence suggests that almonds can facilitate gut microbiota improvement which also strengthens immunity.
Seeds
